Assessment of watershed management implemented on springal peak flood discharge and flood volume, using HEC-HMS model (case study: Kushk Abad sub-basin in Iran)

Assessment of watershed management operation is one of the main subjects for future planning of practical projects and natural resources management. Flood Damage is one of the most important problems in countries same Iran, which is mostly, affected most parts of the country and caused hazards. Ther...
