Summary: Forests play a critical role in the hydrologic cycle and it is important to accurately represent forest dynamics in watershed models. This study focuses on improving the representation of forest dynamics in the widely used Soil and Water Assessment Tool (SWAT) through species-specific re-parameterizations. The results show that the re-parameterized model outperforms the default model in simulating forest dynamics and has significant implications for water yield in the studied sites.

Summary: This study focuses on the application of the semi-distributed hydrological model in the semi-arid regions of India. The SWAT model was used to simulate stream flows for a total basin area of 32,927 km(2) over a period of 20 years. The SCS runoff curve number (CN2) was identified as the most sensitive parameter. The model performed well in calibration and validation, showing good to satisfactory results based on R-2, NSE, and PBIAS indicators. DEM data was used to delineate the watershed and identify the highest groundwater, surface discharge, and evapotranspiration in specific subbasins. The wettest year was 2006, while the driest was 2000.

Summary: The aim of this study is to evaluate the distribution of hydrological responses towards water balance components for a watershed. The study focused on the water balance in the Mahanadi river basin of India, analyzing the impact of Landuse Land Cover (LULC) on runoff using the SWAT model. The results showed that significant increases in runoff and decreases in groundwater contribution were observed from 1994 to 2014 due to changes in LULC.

Summary: A hydrological simulation study in the Xiaoxingkai Lake Basin, China, reveals that climate change has a greater impact on streamflow than land use/land cover changes. The volume of Lake Xiaoxingkai slightly increased during 1961-2017, with climate change contributing the most, followed by direct human activities and land use/land cover changes having a negative effect.

Summary: Hydrological modeling using the SWAT model was conducted to simulate and evaluate the hydrological behavior of the Nashe watershed. The sensitivity of parameters and performance of the model were assessed using different algorithms. Seasonal water balance analysis revealed the variations in water budget for different periods in the catchment.

Summary: Understanding hydrological processes using hydrological model parameters is crucial for effective water resources management. This study employed the Soil and Water Assessment Tool (SWAT) model to analyze the water balance in the Yeongsan River Basin, South Korea, which is dominated by summer monsoon rains. A new multi-site calibration approach-based SWAT hydrological model was developed and successfully reproduced the hydrological trend and average discharges of the basin for 42 years. The study also revealed the importance of monsoon rains in sustaining the water supply in the basin.

Summary: Land use and land cover change significantly impact watershed hydrological processes, with implications for water balance monitoring. This study examines how changes in land use and cover in the Nashe watershed affect hydrological parameters, predicting increases in surface runoff due to agricultural and urban expansion. The gradual increase in grassland and rangeland from 2035 to 2050 may help mitigate these effects on water resources management.

Summary: Himalayan rivers play a crucial role in water supply for northern India, with snowmelt runoff being the main contributor to river discharge. Climate change is expected to increase precipitation and temperature, leading to a rise in streamflow by over 11%-19% at the end of the century under different emissions scenarios.

Summary: This study highlighted the importance of considering LULC scenarios in rural catchment hydrology for future water dynamics. By involving stakeholders, a mapping protocol was developed to assess the impact of different scenarios on water balance components. Results showed that allocating permanent land covers such as grassland could help buffer water dynamics, promoting land and water conservation.

Summary: This study assesses the hydrological responses of land cover changes in the Muger watershed from 1986 to 2020. The key findings are that changes in cultivation land, forest land, and settlement have significant impacts on the hydrological processes. The study outcome can assist decision-makers and planners in preparing adaptable strategies under changing land cover conditions within a watershed.

Summary: Water resources are crucial for economic prosperity, food security, and human habitats, but their deterioration and inadequate use have significant impacts on the environment and humans. This study used a hydrologic model to simulate and quantify water balance components in the R'Dom watershed in Morocco, revealing the distribution of precipitation, evapotranspiration, surface runoff, and groundwater recharge.

Summary: Groundwater in Ethiopia is threatened by rapid urbanization and industrial expansion, with recharge mostly occurring from July to October. SWAT model was used for recharge estimation, while MODFLOW 2005 was utilized for groundwater flow system numerical simulations, revealing areas of interactions between the river and groundwater. The study suggests that increasing pumping rates or reducing recharge poses significant risks to groundwater sustainability in the area.

Summary: This study examines the responsiveness of hydropower projects to flow variation and introduces the concept of flow elasticity of power (e). The research analyzes the characteristics of run-of-river (ROR) and storage type (ST) projects and their responses to topographical parameters. The findings highlight the importance of topography in power production and its elasticity. The concept of e contributes significantly to the hydropower sector and has practical applications in project planning, designing, operation, and updating stages.
