The main purpose of the present study was to monitor actual contamination levels and execute a comparative assessment of results in a mid-sized Hungarian city for two different years. The first citywide soil investigations were completed in 2011. In 2018, the most prominent properties (pH, CaCO3, texture, and trace metals Cd, Co, Cu, Ni, Pb, and Zn) were reanalyzed and were supplemented with mesofauna on selected sites. The available trace metal elements of urban soils showed the following tendency in 2011: Zn > Cu > Pb > Cd > Cr = Ni = Co. In 2018, the previous order changed to Zn > Pb > Cu > Cr > Cd = Ni = Co. Cd and Pb enrichments were found, especially near the M7 motorway. The comparison between 2011 and 2018 revealed soil contamination was, on average, higher in 2011. Soil microarthropod communities were sampled and assessed using abundance data and diversity measurements. Soil biological quality was evaluated with the help of the Soil Biological Quality (QBS-ar) index. Acari and Collembola appeared to be the most abundant, ubiquitous taxa in the samples. Simultaneously, important groups like Symphyla, Protura, and Chilopoda were completely absent from the most polluted sites. For the most part, lower taxa richness, diversity, and QBS-ar index were observed with higher available Cu Zn, and Pb concentrations.

In the Hidegvíz Valley experimental catchment in Hungary the meteorological data have been collected since the 1990s and used for various purposes including hydrological studies. Current research began in 2018–19, that aimed to reveal the connections between the hydrological and botanical characteristics in riparian forests and a wet meadow. Changes that occurred in both ecosystems in the groundwater levels, soil moisture and vegetation, showed that the local meteorological events influence these factors. Therefore we decided to analyse longer periods in which meteorological extremes
strongly influenced hydrological conditions and so status of ecosystems. Further measurements and their analysis were also required because more accuracy and detail were needed for future water balance modelling.
The measured data between 2017–2020 were chosen as a starting database. For the first analysis we selected three meteorological parameters, i. e. the precipitation, the air temperature, and the air humidity. These parameters were measured by automated instruments, except for the precipitation. We found that the automated tipping-bucket rain gauge needs validation by a manual measurement (Hellmann-type rain gauge), because the data that collected by the automated device will be invalid if the rain intensity is too high.
In 2017 and 2018, the annual precipitation was distributed evenly, but in the following two years we observed some extremes. In 2019 and
2020, the spring was especially dry, the lowest monthly sum was 1.2 mm in 2020 April. 2019 April was similar (19.5 mm), but after the drought
period intense rainfall events arrived in May, resulted a monthly total of 214.1 mm. Air temperature and air humidity has not been showed such extremes as the precipitation.
This study showed that detailed analysis of meteorological parameters is crucial for hydrological modelling data preparation because errors and extreme event can cause serious problems during modelling process and, also in case of evaluation of model results.

The current climatic conditions of the Hungarian Great Plain is not adequate for the forest cover. Surplus water is essential to maintain good ecological status and growth rate of forests. Moreover, in the drying climate of the Great Plain without excess water the survival of forest vegetation is questionable.
In this study, we try to indicate the positive effect of the excess water on the growth of the trees next to the Danube in Gemenc wetland (close the southern border of Hungary). The logging data were collected from 2000 to 2009. Sampled forest compartments were clustered into two groups based on the stand position to the levee (exposed to inundation of Danube or not). The effects of the Danube are evaluated using local hydrological measurements (e.g. gauge at Mohács).
The forest growth itself is not the best indicator because it is also influenced by several other ecological variables. To control better these variables two forest stands were selected aged about 110 years. One of them is located behind a summer levee (low crown height levee), which is inundated only by the high floods. Another forest compartment is outside the main levee and never inundated. These stands are sampled to prepare dendrochronological analysis, which gives us higher time-resolution data. We hope these analyses will help us to interpret the relationship between forest growth and water
conditions.

Climate change induced drought periods are likely to cause decline in groundwater level,
which can degrade riparian ecosystems (such as riparian forest). With a reasonable water
supply, water scarcity can be stopped and these valuable ecosystems can be preserved.
The aim of the research was to evaluate the impact of water supply interventions regarding
habitat reconstruction of Doroszló meadows near Kőszeg (west Hungary). Groundwater
monitoring wells have been installed at 4 representative sites of the area. Groundwater wells
were 3–5 m deep and screened at their bottoms (2–4 m). The water level of the wells was
recorded manually, on a weekly basis, with an accuracy of 1 mm. In the neighborhood of the
wells surface close soil moisture values were also measured. Data from April 2019 to
October 2020 were collected. Local meteorological data measured in Kőszeg were also
used for analysis.
Evaluating the data from each well in the pre-intervention period (the analysis of the
relationship of the wells with the control well), we came to the conclusion that the Well-1 and
Well-2 behave similarly. The impacts of the water supply on the groundwater level were
analysed using a “double mass curve” and a “treatment-control space-time deviations”
approach. Result showed that the intervention had a positive effect only on the Well-3 from
the examined wells. The data evaluation denoted that unfortunately the control well was also
affected by water supply interventions.

The reconstruction of a wood pasture area and a marsh meadow and thereby achieve a more complex biodiversity are the aims of an ongoing project in Western Hungary (Kőszeg Mountains, Őrség National Park Directorate). Previously, the project area (70 hectares) was used as pasture and as meadow. Later it was abandoned, resulted in an increased spread of shrubs and weeds. Climate change may harm the water balance of the vulnerable wetlands. To ensure and manage the water supply and retention in the project area several interventions are planned. The hydrological investigations started in April 2019. Groundwater levels and surface soil moisture (at the surroundings of the wells) are monitored manually once a week at the four selected points in the area. According to the initial results, the groundwater levels and the surface soil moisture values follow the typical seasonal change. A decrease can be detected during the vegetation period, while an increase started in the dormant season. Since the measurements started before the installation of the water control structures and the grazing, the current results can be interpreted as the results of the control period. Thus, the effects of the water supply and retention will be subsequently analyzed.

Manual throughfall gauges can not apply to explore the temporal properties of precipitation redistribution. To follow the interception temporarily it is necessary to use automatic gauges. Commercial rainfall data-loggers are suitable but in a spatially heterogeneous environment, like agroforestry systems, need a large number to represent the spatial differences. To reduce the cost, we started to develop a microcontroller-based data logger.
As a test case, we develop new auxiliary equipment for an already working custom trough in our riparian alder plot. It is a large surface trough with a big container where water level change is sensed. This gauge works with a commercial data logger which will be used for validation purposes. The planned addition is a tipping bucket, which provides a digital signal directly. The simple task is to log the timestamp of the tips. After many iterations, an ARM
Cortex-M0+ based architecture was selected, which integrates all the necessary components of a simple data logger. The development is fully open-source shared through git (https://github.com/kaliczp/hvlog). The presentation shares the experiences accumulated during the continuous development.

Spatially distributed evapotranspiration (ET) data are crucial for the water balance calculations of the different ecosystems. The increasingly used remote sensing-based ET estimation methods allow to obtain information about spatial variability of ET at the field and regional scales. For Hungary, the most reliable actual evapotranspiration mapping model is the CREMAP (Calibration-Free Evapotranspiration Mapping), which uses MODIS surface temperature data. However, its 1 km2 resolution is too coarse to be effectively used for smaller scale operations such as precision forest management or agroforestry systems. Therefore, the CREMAP ET was statistically downscaled to the resolution of 250 m * 250 m with MODIS NDVI data as a co-variable. The downscaled data were used for the comparison of ET of different forest stand types during a dry period and a wet period.

Climate extremes affect the vitality and health of the berry species. In some regions, if enough water is available, the impacts can be reduced. Long-lasting stress effect causes sunscald in case of leaves and berries. There are resistant and susceptible varieties of berry species. The disorder, likely caused by ultra-violet radiation, appears on susceptible varieties when the temperature suddenly increases (above about 30 °C), but the humidity is low. It can easily occur in the presence of wind.
Agroforestry systems offer a possible way to reduce direct sunlight by shading to sensitive agricultural crops. The humidity of the tree canopy can decrease the effect of hot dry air. Trees protect the berry species by slowing wind speed. This ongoing research focuses on how trees can influence the hydrological conditions.
We installed a research plot to study the spatial and temporal variability of soil moisture and groundwater level in an agroforestry system compared with agricultural field without trees (Fertőd, Hungary). The measurement is completed with local climatic parameters such as precipitation, air temperature, and relative humidity. The species of the measured plots are blackberry (Rubus fruticosus ‘Dirksen’), raspberry (Rubus idaeus ‘Fertődi zamatos’), and blackcurrant (Ribes nigrum ‘Otelo’) with integrated shadowing trees: hybrid poplar (Populus x euramericana).

Riparian zone forests are a special type of agro-forestry systems. As buffer zones protect stream systems against stress factors. These ecosystems are diverse so ecologically valuable, on the other hand, they are valuable (because of high productivity) from an economic viewpoint as well.
Riparian forests are very vulnerable because they strongly depend on surplus water (shallow groundwater or seasonally flooded condition). Long drought periods caused by changing climate induce lowering of the water table and shortening flooded periods. With reasonably designed water supply systems, these negative processes can be stopped, and valuable ecosystems can be preserved.
The effect of an artificial structures (new lakes and bottom thresholds) induced water supply was evaluated in Kaszó Forest (Somogy county, Hungary). Eco-Hydrological monitoring (groundwater and phenological) was conducted on 14 regular (under the effect of water supply interventions) and 4 control plots in different forest ecosystems. The impact of water supply interventions was interpreted with spatio-temporal groundwater level difference analysis and found that surplus water had a positive effect on the riparian zone water table (40-50 cm rise in the neighbourhood of new lakes) and vegetation.
A complex field monitoring (hydro-meteorological and phenological measurements) was conducted on three representative locations. 1-D Hydrus model was successfully calibrated for an alder and two common oak forest plots. Diurnal signal of groundwater levels was used for ET estimation in the model. Model results showed that groundwater uptake of forest vegetation was significantly increased (30%) regarding water supply interventions.

Eco-hydrology of hydrophyte forests and wet meadows are very important question in changing climate. Hydrological extremes can cause in these habitats droughts, intense rainfall events and floods. In this study, we investigated a riparian alder forest and its edge, and a neighbouring meadow in Hidegvíz Valley experimental catchment to compare different surface cover type hydrological and botanical characteristics. The research has conducted in 2018-2019 hydrological year.
Throughout the botanical study, a list has been made of the various plant species – trees, bushes, and herbs - of the elder woodland and its edge, and the grassland, in each vegetation period. The classifications of the habitats were made by the Á-NÉR system, which is a Hungarian classification system for Hungarian habitats.
The hydrological research was focused on three important factors in the one-year period: precipitation, the changes of the groundwater levels, and the soil moisture values. We summarised the monthly data, and from all this, we calculated an annual water balance graph. This graph showed us a correlation between hydrological extremes and soil moisture value changes.

Urbanization and related environmental pollution have strong effects on stream systems by inducing short duration high-peak floods, raised levels of nutrients and contaminants, altered channel geomorphology, sediment dynamics, and reduced biotic richness. The main purpose of this current study is to detect stream contamination levels in a mid-sized Hungarian city by comparing the results of two separate years (2011, 2018). Discharge, channel geomorphology, and water quality parameters were measured, and load-based contamination was calculated for the city's main watercourse (Gaja Brook). The pH, CaCO3, texture, and heavy metal contents – Cd, Co, Cu, Ni, Pb, and Zn – were reanalysed in the sediment for both investigated years. For comparison, enrichment factors were used to determine sediment accumulation. As a complex parameter, biological water quality was also determined using BMWP and MMCP protocols in 2018. The results show that conductivity and the nutrient concentrations were higher, but the discharge values were lower in 2011 than in 2018. The nitrate load doubled both times in the brook between the first and the last sampling sites. The enrichment factors decreased or stagnated when the values of the two years were compared, but severe enrichment of Cd was detected in the middle of the city and south of the city. The aquatic macroinvertebrate fauna structure defined clean, but slightly impacted watercourses north and south of the city as well, but the abundance and presence of sensitive taxa differed at the sampling sites. Székesfehérvár has better than expected water quality, which can be attributed to the good ecological states of the hydromorphology and the streamside zone.

The water balance of Zala County was analyzed using remote-sensing based actual evapotranspiration (ETA) (Kovacs 2011) and runoff (R) in the context of land cover types. The highest mean ETA rates were determined for water bodies (658 mm/year) and wetlands (622 mm/year). Forests have higher values than agricultural areas, and the lowest rates belong to artificial surfaces. Mean annual runoff is the largest on artificial surfaces (89 mm/year), and it decreases on the other land cover types. For climate change impact analysis a Budyko-model was used in spatially-distributed mode. The parameter of the Budyko-model (α) was calculated for pixels without surplus water. For the extra-water affected pixels a linear model with β-parameter (actual evapotranspiration / panevapotranspiration) was used. These parameters (α and β) can be used for evaluating future ETA and R in spatially-distributed mode. According to the predictions, the mean annual evapotranspiration may increase about 27 mm while the runoff may decrease to the one third to the present amount by end of the century

Models that describe hydrological processes in forests may help to estimate the consequences of forestry interventions or of climate change. The authors employed a hydrologic model for estimation of forest litter interception of a middle-aged sessile oak (Quercus petraea) stand. Antecedent water content and the storage capacity of the forest litter were the main parameters of the model. The antecedent water content of the litter was estimated by the daily precipitation and temperature data, collected in Hidegviz Valley research catchment in a three year measurement period (2006-2008). The measurements were done by an instrument we developed ourselves, where the undisturbed forest litter samples were enclosed in frames and measured in daily time steps.

The forest area in Hungary has increased during the last century from 1.1 to 2.0 million ha. The European Union supports further afforestation so roughly 15 -18 000 hectares are being planted each year, mostly on the Hungarian Great Plain. Water uptake of forests from groundwater can be significant in shallow groundwater areas of the Hungarian Great Plain especially in drought periods. Therefore forests can induce water table depression and subsurface salt accumulation above saline water table in areas with a negative water balance. The impact of forests is examined by a systematic study on the Hungarian Great Plain., An oak forest and a pasture groundwater uptake and salt accumulation effect were compared at the stand scale. Under the forest the water table levels were roughly 0.5 m lower than under the pasture, and the groundwater uptake of the oak plot was more than twice as great. Larger forest groundwater use is not followed by a higher salt uptake. Therefore slight salt accumulation was measured both in the soil and also in the groundwater. Higher groundwater uptake may cause more significant salt accumulation under pronounced drought conditions of a warmer climate.

Diurnal fluctuations of hydrological variables (e.g., shallow groundwater level or streamflow rate) are comparatively rarely investigated in the hydrologic literature although these short-term fluctuations may incorporate useful information for the characterization of hydro-ecological systems. The fluctuations can be induced by several factors like (a) alternating processes of freezing and thawing; (b) early afternoon rainfall events in the tropics; (c) changes in streambed hydraulic conductivity triggered by temperature variations, and; (d) diurnal cycle of water uptake by the vegetation. In temperate climates, one of the most important diurnal fluctuation-inducing factors is the water consumption of vegetation, therefore a detailed overview is provided on the history of such research. Beside a systematic categorization of the relevant historical studies, models that calculate groundwater evapotranspiration from diurnal fluctuations of groundwater level and/or streamflow rate have been reviewed. Compared to traditional evapotranspiration estimation methods these approaches may excel in that they generally employ a small number of parameters and/or variables to measure, are typically simple to use, and yet can yield results even on a short time-scale (i.e., hours). While, e.g., temperature-based methods of evapotranspiration are simple too, they cannot be applied or become inaccurate over shorter time periods. Similarly, traditional approaches (such as eddy-correlation or Bowen-ratio based) are accurate for shorter time steps but they require a number of measurable atmospheric input variables.
