| description | Recent history shows that floods have become a frequently occurring disaster in Balochistan, especially during
monsoon season. Two rivers, river Porali and river Kud overflows, inundating its banks and causing destruction to cultivated land
and property. This study is an attempt to identify flood prone areas of Porali river basin for future flood scenario and propose
possible reservoir locations for excess flood water storage. Computer-based models Hydrological Simulation
Program-FORTRAN (HSPF) and HEC-river analysis system (HEC-RAS) are used as tools to simulate existing and future flood
and drought scenarios. Models are calibrated and validated using data from 3 weather stations, namely Wadh, Bela, and Uthal and
stream flow data from two gauging stations. The highest and the lowest 10 years of precipitation data are extracted, from historic
dataset of all stations, to attain future flooding and drought scenarios, respectively. Flood inundation map is generated
highlighting agricultural prone land and settlements of the watershed. Using Digital Elevation Model (DEM) and volume of water
calculated from the flood scenario, possible locations for reservoirs are marked that can store excess water for the use in drought
years. Flow and volume of water has also been simulated for drought scenario. Analyses show that 3 × 109 m3 of water available
due to immense flooding that is sufficient for the survival for one drought year, as the volume of water for latter scenario is 2.9 ×
108m3. |
