Short summary
We compare seven meteorological drought indices that are commonly used to predict future droughts. Our goal is to assess the reliability of these indices to predict hydrological impacts of droughts under changing climatic conditions, using an integrated hydrological model. Drought indices are able to identify the timing of hydrological impacts of droughts in present and future climate. However, these indices can not estimate the severity of hydrological impacts of droughts in future climate.
