Regional drought assessment using a distributed hydrological model coupled with Standardized Runoff Index

Regional drought assessment using a distributed hydrological model coupled with Standardized Runoff Index

Drought assessment is essential for coping with frequent droughts nowadays. Owing to the large spatio-temporal variations in hydrometeorology in most regions in China, it is very necessary to use a physically-based hydrological model to produce rational spatial and temporal distributions of hydro-me...

Owing to the large spatio-temporal variations in hydrometeorology in most regions in China, it is very necessary to use a physically-based hydrological model to produce rational spatial and temporal distributions of hydro-meteorological variables for drought assessment. In this study, the large-scale distributed hydrological model Variable Infiltration Capacity (VIC) was coupled with a modified standardized runoff index (SRI) for drought assessment in the Weihe River basin, northwest China. The result indicates that the coupled model is capable of reasonably reproducing the spatial distribution of drought occurrence.

This model also has potential for drought forecasting, early warning and mitigation, given that accurate meteorological forcing data are available.https://www.proc-iahs.net/368/397/2015/piahs-368-397-2015.pdf
