Data description: This dataset contains the time series of area values for 7246 global reservoirs (with an integrated capacity of 6810 km3) from 1984 to 2020 (updated). It was based on the dataset by Pekel et al. (2016), with the contaminations from clouds, cloud shadows, and terrain shadows corrected automatically.

Model Description: A multi-purpose reservoir module was integrated into the Distributed Hydrology Soil Vegetation Model (DHSVM; Wigmosta et al., 1994). Conditional operating rules, which are designed to reduce flood risk and enhance water supply reliability, were adopted in this module.

Conceptual representation of DHSVM-Res includes: (a) topographically based basin discretization in DHSVM; (b) water movement for each grid cell; and (c) the newly integrated, multi-purpose reservoir with a flood control pool, a conservation pool, and an inactive pool. Blue points in (a) represent the point reservoirs that can be simulated in the integrated model.
