The impacts of floods and droughts are intensified by climate change, lack of preparedness and coordination. The average rainfall in study area is ranging from 200 mm to 400 mm per year. Rain gauge ge
The problem of black soil degradation is serious in the northeast of China. The aim of the present work is to evaluate the black soil loss due to water erosion in the 228,030 ha area of Ashihe river.
In recent years, integrated watershed management studies have gained importance in Turkey. In the adaptation of European Union full membership process of Turkey, integrated watershed management plans
Evaluating the ecological impacts of climate change on water resources is an integral part of hydrological and ecological investigations, land and resource management in the twenty-first century.
Alterations in climate variability and change will lead to changes in hydrological cycle, thus influencing the fate and transport of nitrogen pollutant. This impact assessment study evaluated the long
A modified SWAT is implemented to enhance the skill of the model to simulate streamflow in a complex tropical catchment characterised by wetlands, ponds, canals and braided channels. This landscape pl
The total nitrogen loss to receiving water bodies is the primary causes of surface water deterioration. The identification of critical source area(CSA) is extremely important and meaningful to prevent
The Soil and Water Assessment Tool (SWAT) model has been applied worldwide to support sustainable land and water management. However, the consequences of these practices for carbon cycling are not ade
Model calibration is an important process for the usage of watershed models, but the calibration process is often time-consuming and the result is often not quite satisfying. In this study, a universa
Hydrologically, Rietspruit sub-basin is located in the Vaal Basin, an environment that is inevitably highly threatened both in terms of water quantity and quality. Threats are a result of existing hig
