Evaluation of hydrological modeling using climatic station and gridded precipitation dataset

The conventional rainfall data estimates are relatively accurate at some points of the region. interpolation such type approximates actual rainfield however in scarce regions; resulted is rough estimate events. In regions like Indus basin Pakistan, obtained through remote sensing can be very useful. This research evaluates two types gridded i.e., European Reanalysis (ERA) interim and Japanese 55 years (JRA-55) along with climatic station for three small dams Pakistan. Since no measured flow available these dams, nearest possible catchments where calibrated parameters then used simulating from all using Soil Water Assessment Tool (SWAT). results comparison rainguage precipitation shows that highly overestimates data. Similar were observed simulated by SWAT model. Peak flood calculated JRA-55 while Era-Interim peak floods comparable to stations catchments.
