232 Indonesian Dams Dataset

This dataset presents the river length, slope, and SCS curve number (CN) of the dam’s catchments. The dam coordinates were acquired from the visual identification of satellite imagery and cross-checked with the government’s data. The river length and slope of the reservoir watersheds were calculated using HEC-HMS 4.11 software. The curve number was identified using an R script with the aid of the national land use map and hydrologic soil group type map. This dataset aims to provide reliable Indonesian reservoir watershed data for hydrology modeling, reservoir operation, and maintenance.
