The precise estimation of surface runoff from rainfall is critical for water resource management. In the recent past, remote sensing and Geographic Information System (GIS) technologies have been widely used in the estimation of surface runoff from watersheds, and from agricultural fields in part...

This study examines the global patterns and impacts of droughts through the mapping of several drought-related characteristics - either at a grid or a country scale. Characteristics cover various aspects of droughts from global distribution of meteorological and hydrological drought risks to soci...

Streamflow data play a key role in water resources management; however these data are not often available. One of the alternatives then is to use the rainfall-runoff models, but in most cases the required inputs such as rainfall and evapotranspiration are not available to use these models. Freely...

Estimation of actual evapotranspiration (AET) and its spatial distribution are important to understanding of catchment hydrology. The AET is driven by net energy available to evaporate water from soil and vegetation surfaces, and to transpirate water from vegetation. However, estimating AET is di...
