Estimation of hydrological changes in a tropical watershed using multi-temporal land-use and dynamic modelling

The response of a watershed due to changes in its physical environment might result in floods, river erosions and siltations, subsequently affecting humans and biotas. Evaluating land-use changes is crucial for better assessment of hydrological conditions in a watershed system. The remote sensing im...

Estimation of hydrological changes in a tropical watershed using multi-temporal land-use and dynamic modelling
description The response of a watershed due to changes in its physical environment might result in floods, river erosions and siltations, subsequently affecting humans and biotas. Evaluating land-use changes is crucial for better assessment of hydrological conditions in a watershed system. The remote sensing imagery, field data collection, and land change modelling were used to produce the land-use maps of different spatiotemporal scale from 1989 to 2039. The generated maps are integrated into Hydrological Simulation Program-Fortran (HSPF) model, to evaluate the hydrological changes in Skudai River watershed in Malaysia. Total runoff is expected to account for 57% of the rainfall influx by 2039, a change of 2% from 1989 land-use, an indication of the low response of runoff to change in land-use. As built-up land increase by 3.39%, the average streamflow will increase by 0.05 m3/s.
