In recent decades, Algeria has experienced rapid and irregular demographic growth, and this irregular change has inevitably led to periodic floods threatening human life. Urbanization, an anthropogenic cause, is rapidly evolving and has been considered as a non-negligible part in altering land use and land cover (LULC), despite the fact that precipitation characteristics are related to the climate of the region and may change over time. It is therefore essential to assess the changes in runoff as a result of LULC changes. Awareness of the relationship of rainfall and runoff is necessary for urban drainage network modeling and design. The implementation of Low-Impact Development (LID) is a popular strategy to minimize stormwater runoff and pollutant loads. In developed countries, software to estimate impacts of certain LID controls has expanded in recent years; however, readily available modeling approaches are still in high demand in developing countries, such as Algeria. In this article, we seek methods that can decrease runoff peaks and volume for the Guelma watershed located in northeast Algeria by integrating the Personal Computer Storm Water Management Model (PCSWMM) and a geographic information system (GIS). PCSWMM calibration is conducted by using the sensitivity-based radio tuning calibration tool. The Nash–Sutcliffe efficiency (NSE) (0.70–0.88), coefficient of determination (R2) (0.76–0.96), and relative error (RE) (0.018–0.23) indicated good model performance in this urban watershed. The implementation of five LID practices, including permeable pavements, bioretentions, rain gardens, infiltration trenches, and rainwater harvesting systems, in scenarios explored could reduce peak runoff by 54.7% and reduce total runoff volume by 75.2%. The current research will assist decision-makers in improving and choosing the most appropriate LID designs that are effective in view of future climate changes and changes in LULC. This study can contribute to further applications of rainfall–runoff models in Algeria.

Texas, USA Texas is a large state in the US that experiences a diversity of climate conditions and water demands. In this study, 130 stream gauging sites and their associated watershed physical and geological properties were used to develop multiple regression models to predict the Baseflow Index (BFI) across Texas. Calculated BFI was derived from daily streamflow data from 1980 to 2017 using the two-parameter recursive digital filtering approach of the Web-based Hydrograph Analysis Tool (WHAT). Three scenarios were developed and validated. The first two scenarios related BFI to topography, climate, and land use. The third scenario used surface geology, soil type and hydrogeology parameters. The models developed showed high performance, low bias, and low relative errors to predict BFI, with R2 values varying from 0.72 to 0.99, and strong agreement with filtered BFI values. The results further showed that there was no specific pattern for BFI variation across Texas ranging from 0.29 to 0.51. Outputs indicated that models developed for scenarios 1 and 3 had higher prediction performance. Additionally, evapotranspiration (ET) contributed to lower model accuracy, since the ET was not categorized as proportional to the percentages of cultivated areas within each basin, but was generalized to represent the whole catchment. The developed models that are reported here can support further research in groundwater modeling and baseflow prediction for ungauged sites that have similar characteristics.

Alteration of land use and climate change are among the main variables affecting watershed hydrology. Characterizing the impacts of climate variation and land use alteration on water resources is essential in managing watersheds. Thus, in this research, streamflow and baseflow responses to climate and land use variation were modeled in two watersheds, the Upper West Branch DuPage River (UWBDR) watershed in Illinois and Walzem Creek watershed in Texas. The variations in streamflow and baseflow were evaluated using the Soil and Water Assessment Tool (SWAT) hydrological model. The alteration in land use between 1992 and 2011 was evaluated using transition matrix analysis. The non-parametric Mann–Kendall test was adopted to investigate changes in meteorological data for 1980–2017. Our results indicate that the baseflow accounted for almost 55.3% and 33.3% of the annual streamflow in the UWBDR and Walzem Creek watersheds, respectively. The contribution of both land use alteration and climate variability on the flow variation is higher in the UWBDR watershed. In Walzem Creek, the alteration in streamflow and baseflow appears to be driven by the effect of urbanization more than that of climate variability. The results reported herein are compared with results reported in recent work by the authors in order to provide necessary information for water resources management planning, as well as soil and water conservation, and to broaden the current understanding of hydrological components variation in different climate regions.

The change in both streamflow and baseflow in urban catchments has received significant attention in recent decades as a result of their drastic variability. In this research, effects of climate variation and dynamics of land use are measured separately and in combination with streamflow and baseflow in the Little Eagle Creek (LEC) watershed (Indianapolis, Indiana). These effects are examined using land-use maps, statistical tests, and hydrological modeling. Transition matrix analysis was used to investigate the change in land use between 1992 and 2011. Temporal trends and changes in meteorological data were evaluated from 1980–2017 using the Mann–Kendall test. Changes in streamflow and baseflow were assessed using the Soil and Water Assessment Tool (SWAT) hydrological model using multiple scenarios that varied in land use and climate change. Evaluation of the model outputs showed streamflow and baseflow in LEC are well represented using SWAT. During 1992–2011, roughly 30% of the watershed experienced change, typically cultivated agricultural areas became urbanized. Baseflow is significantly affected by the observed urbanization; however, the combination of land and climate variability has a larger effect on the baseflow in LEC. Generally, the variability in the baseflow and streamflow appears to be heavily driven by the response to climate change in comparison to variability due to altered land use. The results reported herein expand the current understanding of variation in hydrological components, and provide useful information for management planning regarding water resources, as well as water and soil conservation in urban watersheds in Indiana and beyond.
