This paper is aimed at developing a geostatistical model to improve interpolated annual and monthly rainfall variation using remotely- sensed cold cloud duration (CCD) data as a background image. The data set consists of ...

A distributed GIS-based hydrological model is developed using GIS and computational hydrology techniques. The model is based on water balance consideration of the surface and subsurface processes. The surface water balance ...
