Meteorological drought is a natural hazard that can occur under all climatic regimes. The drought monitoring is a vital and important part of predicting and analyzing the drought impacts. Due to the fact that no single index can represent all facets of meteorological drought, a multi-index approach was used for drought monitoring in this investigation. The ability of eight precipitation-based drought indices was assessed based on analyzing the historical meteorological data (1988–2019) of In Guezzam in the South of Algeria. Those indices are the standardized precipitation index (SPI), percent of normal index (PNI), deciles index (DI), and Z-score index (ZSI), the dry flow index (ISD), normalized hydrological index (IHN), log-decimal index of hydrological deviations (ILDH), and precipitation deciles (PD). Thus, the methodology is tested on a real-world system which allows assessing its applicability within a Drought Watch System in river basins with significant storage works. The obtained results highlighted that the selection of database was more important than the selection of drought index and that the best combinations were the PD, PNI, and DI calculated with SPI and ZSI.

Drought is a slow-onset, creeping natural hazard and a recurrent phenomenon in the arid and semi-arid region of the Mekerra watershed. Numerous drought indices have been used in different countries to implement drought mapping and monitoring of water resources management. This investigation proves meteorological drought index combined with remote sensing drought index, but had unsteady spatial and temporal variation. The results highlight that droughts occur in semi-arid climatic region of Sidi Bel Abbes at the Northern part of the watershed. The various drought indices differ in their detection and classification of this extreme climatic event in the study area. There is high correlation (r > 0.68) among the eight indices, with PD (Precipitation deciles), DI (Deciles Index), and PNI (Percent of Normal Index) showing the highest relationship to SPI (r = 0.95 and r = 0.99 respectively). The differences observed among the drought indices in detecting drought events in the study area can be reduced by using multiple drought indices in addition to the use of SPI (Standardized Precipitation Index) in drought assessments especially at the area of Sidi Bel Abbes since technological advancement in drought monitoring software’s has made it easier. In addition, it is worthwhile to investigate on why drought detection varies with indices. Furthermore, considering the advantages and disadvantages of the mentioned drought predictors in this study area will enhance the understanding of vegetation responses to drought threatens.

Climate change projections predict the increase of no-rain periods and storm intensity resulting in high hydrologic alteration of the Mediterranean rivers. Intermittent flow Rivers and Ephemeral Streams (IRES) are particularly vulnerable to spatiotemporal variation of climate variables, land use changes and other anthropogenic factors. In this work, the impact of climate change on the aquatic state of IRES is assessed by the combination of the hydrological model Soil and Water Assessment Tool (SWAT) and the Temporary Rivers Ecological and Hydrological Status (TREHS) tool under two different Representative Concentration Pathways (RCP 4.5 and RCP 8.5) using CORDEX model simulations. A significant decrease of 20–40% of the annual flow of the examined river (Tsiknias River, Greece) is predicted during the next 100 years with an increase in the frequency of extreme flood events as captured with almost all Regional Climate Models (RCMs) simulations. The occurrence patterns of hyporheic and edaphic aquatic states show a temporal extension of these states through the whole year due to the elongation of the dry period. A shift to the Intermittent-Pools regime type shows dominance according to numerous climate change scenarios, harming, as a consequence, both the ecological system and the social-economic one.

The non-perennial streams and rivers are predominant in the Mediterranean region and play an important ecological role in the ecosystem diversity in this region. This class of streams is particularly vulnerable to climate change effects that are expected to amplify further under most climatic projections. Understanding the potential response of the hydrologic regime attributes to climatic stress helps in planning better conservation and management strategies. Bouregreg watershed (BW) in Morocco, is a strategic watershed for the region with a developed non-perennial stream network, and with typical assets and challenges of most Mediterranean watersheds. In this study, a hybrid modeling approach, based on the Soil and Water Assessment Tool (SWAT) model and Indicator of Hydrologic Alteration (IHA) program, was used to simulate the response of BW's stream network to climate change during the period: 2035-2050. Downscaled daily climate data from the global circulation model CNRM-CM5 were used to force the hybrid modeling framework over the study area. Results showed that, under the changing climate, the magnitude of the alteration will be different across the stream network; however, almost the entire flow regime attributes will be affected. Under the RCP8.5 scenario, the average number of zero-flow days will rise up from 3 to 17.5 days per year in some streams, the timing of the maximum flow was calculated to occur earlier by 17 days than in baseline, and the timing of the minimal flow should occur later by 170 days in some streams. The used modeling approach in this study contributed in identifying the most vulnerable streams in the BW to climate change for potential prioritization in conservation plans.

The study of the influence of climate change on the evolution of floods in areas under the influence of a Mediterranean climate is very important. This work aims to provide new analytical elements to decision-makers in flood management and forecasting in three Mediterranean catchments (Lonquen, Evrotas, and Azzaba), in order to better understand their hydrological behavior and to quantify the flow and its vulnerability to climate change. A semi-distributed conceptual model (HBV-A model) was used to simulate flows with a daily time step. The model results (simulated flows) were used to examine the evolution of high flows using two different approaches (linear regressions and statistical test). The Chilean and the Greece catchments show a decrease in flooding. However, the Moroccan catchment reacts differently, since a positive trend in high flows is observed. The overall results confirm the influence of climate change on the rainfall/runoff relationship.

Understanding the spatiotemporal distribution of future droughts is essential for effective water resource management, especially in the Mediterranean region where water resources are expected to be scarcer in the future. In this study, we combined meteorological and hydrological drought indices with the Soil and Water Assessment Tool (SWAT) model to predict future dry years during two periods (2035–2050and 2085–2100) in a typical Mediterranean watershed in Northern Morocco, namely, Bouregreg watershed. The developed methodology was then used to evaluate drought impact on annual water yields and to identify the most vulnerable sub-basins within the study watershed. Two emission scenarios (RCP4.5 and RCP8.5) of a downscaled global circulation model were used to force the calibrated SWAT model. Results indicated that Bouregreg watershed will experience several dry years with higher frequency especially at the end of current century. Significant decreases of annual water yields were simulated during dry years, ranging from −45.6% to −76.7% under RCP4.5, and from −66.7% to −95.6% under RCP8.5, compared to baseline. Overall, hydrologic systems in sub-basins under the ocean or high-altitude influence appear to be more resilient to drought. The combination of drought indices and the semi-distributed model offer a comprehensive tool to understand potential future droughts in Bouregreg watershed.

The “Merdja” is the shallow aquifer of Tebessa plain, located in the northeast of Algeria. The climate is typical of semi-arid steppes, where extensive agro-pastoral activities are dominating. It is still the main water resource used by major sectors. Due to its proximity to the City, it is vulnerable to pollution. According to earlier studies, this aquifer undergoes seasonal water quality fluctuations (between wet and dry seasons), induced mainly through anthropogenic activities. The study is utmost important, as it tracks the groundwater quality and aims to gain an understanding of how the local and natural conditions influence this resource at temporal (interannual) and spatial scales, by following up the evolution trend of hydrochemical parameters of the “Merdja” aquifer. Seventy-one groundwater samples were collected and analyzed from drinking/irrigation wells, through four field measurement campaigns (2001, 2006, 2009, and 2010). The results obtained confirm the fact of water pollution. Point-sources of pollution with nitrate and salinity are revealed on the respective maps of these parameters, especially downstream at the nearby areas of Tebessa City. Non-point sources of groundwater pollution are also manifested. The Piper diagram reveals a relative stability of water type and that rainfall plays a role in the natural remediation, by taking part in the aquifer recharge. The ionic ratios and the principal components analysis highlight that the temporal change of groundwater quality results respectively from: (i) ionic exchange process and the dissolution of evaporites; (ii) the sources of nitrate in groundwater remain the excess application of inorganic nitrogenous fertilizers, organic manures, and wastewater effluents.

Being a laborious approach, manual calibration of hydrologic model in a semi-arid context requires in-depth knowledge of the watershed and as much as possible field input data to obtain reliable simulations. In this study, manual calibration and relative sensitivity analysis approaches of the SWAT model (Soil and Water Assessment Tool) were applied for water balance in a 1993 km2 watershed (on the R’dom river) located in North-western Morocco. The watershed is located in a semi-arid area dominated by agro-forestry activities. The objectives of this study were (i) to perform a local sensitivity analysis of the SWAT model taking into consideration the watershed characteristics and (ii) to implement a detailed methodology of manual calibration and validation of the model in a semi-arid context. Sensitivity analysis has been carried out on 12 different SWAT input parameters, and has revealed that 4 input parameters only were the most influential ones on flow components of the R’dom watershed. Model manual calibration was conducted along 2006 and 2007 by comparing measured and predicted monthly and daily discharges and taking Nash-Sutcliffe coefficient (NSE), determination coefficient (R2), and percent bias (PBIAS) as goodness-of-fit indicators. Validation has been performed by the same approach through 2008 and 2009 period. All final NSE values were above 0.5, R2 values exceeded 0.7, and PBIAS lower than 25% demonstrating satisfactory model performances over the study watershed conditions. The SWAT model set-up with measured input data, manually calibrated and validated, reflects well the real hydrologic processes occurring in the R’dom watershed and can be used to assess current and future conditions and to evaluate alternative management practices.

The spatial assessment of water quality for irrigation is of great importance for agricultural issues. Assessing the suitability of groundwater for irrigation is carried out for the first time in the High Mekerra watershed. Groundwater samples were collected during the wet season (March 2013) and the dry season (July 2013) and analyzed for determining the physicochemical properties. The indices used in the quality assessment were the sodium adsorption ratio (SAR), residual sodium carbonate (RSC), sodium percentage (%Na+), permeability index (PI), magnesium hazard (MH), Kelly’s ratio (KR), and irrigation water quality index (IWQI), incorporating the spatial variation using the GIS-based multi-criteria system. Result showed that most of groundwater samples have low sodium hazard and high to very high salinity hazard and could be used for irrigation on almost all types of soil with little risk of exchangeable sodium. The GIS-based multi-criteria system highlighted the spatial variation of groundwater quality for irrigation in the study area. This spatial distribution indicated that groundwater is generally of moderate quality and that the Ras el Ma aquifer quality is better than for Mouley Slissen aquifer.

Groundwater constitutes the main source of water supply in the High Mekerra watershed of northwestern Algeria. This resource is currently under heavy pressures to meet the growing needs of drinking water and irrigation. This study assesses the geochemical characteristics of groundwater of the High Mekerra watershed at 21 points distributed across the two main aquifers (Ras El Ma and Mouley Slissen) in the region. Hydrochemical facies of Ras El Ma groundwater are dominantly MgCl and CaCl type, while those of Mouley Slissen groundwater are of CaHCO3 type. Principal component analysis shows a strong correlation between groundwater mineralization and Ca2+, Na+, Cl− and SO42− ions stemming from the dissolution of carbonates, gypsum and anhydrite. Groundwater mineralization evolves from south to north. Geochemical modeling shows that the High Mekerra groundwater is saturated with respect to calcite and dolomite and undersaturated with respect to gypsum and anhydrite. Nitrate concentrations that exceed the WHO standard (50 mg L−1) at several points are linked to the agro-pastoral activities in this region.

Environmetric techniques such as cluster analysis (CA) and principal component and time series analysis were used to evaluate variations in surface water in the Babar watershed. The River Arab is monitored at the Babar dam. The later was build for drinking and industrial water supply for the local population. The impounded water is experiencing a degradation of its quality due to different types of pollution, in addition to the natural processes of erosion and leaching of various toxic elements. A total of 21 samples were collected. Eleven variables were determined on every sample representing three different sampling stations. TDS in the saline water was high in the eastern part (S1), low in the western part (S2), and intermediate in the dam (S3). The water type is for S1, for S2 and , mixed water in the dam. In the CA, 7 variables were classified into 2 clusters controlled by and 21 samples are grouped into 3 statistical groups coinciding with the stations S1, S2 and S3. Principal component analysis indicates two principal components (PCs), which explained 87% of the total variance in water quality data set. Two PCs, which are salinization and sulphates, explain 73% and 14% of the total variance, respectively. Time series analysis showed that Ca2+, Mg2+, Na+, Cl− and have very similar trend to TDS and K+ have a similar pattern to . It suggests that five components control TDS.

The hydrochemical and multivariate statistical techniques such as the factor analysis (FA), the principal component analysis (PCA), and the cluster analysis (CA) were used to determine the main factors and mechanisms controlling groundwater chemistry of Ain Djacer Mio-Plio-Quaternary aquifer, Eastern Algeria. Twenty-one groundwater samples of this aquifer were monitored, during March 2013, with the objective of identifying the geochemical processes and their relation with groundwater quality as well as to get an insight into the hydrochemical evaluation of groundwater. The Piper diagram showed that water facies are of a Ca-HCO3-type near limestone limits and SO4–Na in the center part of the plain. The FA and the PCA revealed two factors that explained 65.1% of the total variance in water quality dataset. The first factor is salinization, which shows strong associations between total dissolved solids (TDS), , Cl–, Ca2+, Mg2+, and Na+. The second factor is mostly associated with chemical fertilizers and represents the high positive load of and K+ and the high negative load of pH and . However, the CA, based on major ion contents, defined three main groups, reflecting different hydrochemical processes. The first group has low salinity (TDS < 1,000 mg/l) and a Ca-HCO3 water type. Samples of this group are mostly located in recharge areas and suggest dissolution of carbonate rocks. The third group has high salinity (TDS > 2,000 mg/l) and a SO4–Na water type. Samples from this group are mostly located in the center part of the plain which constitutes the discharge area. The second group has intermediate salinity (1,000 < TDS < 2,000 mg/l) and Ca-Na water type. These three groups present a salinity increasing with groundwater flow direction. The chemical monitoring allowed relating the presence of nitrates in the study area to agricultural activity. This study highlights that reactions responsible for the hydrochemical evolution in this area are of three categories: (1) dissolution of evaporite minerals, (2) precipitation of carbonate minerals, and (3) anthropogenic action.
