FL-TLS-WB-100

"The flood hazard assessment of the selected Sucos was undertaken by quantifying the extent and depth of flooding in the flood prone area for a range of flood frequencies. We analyzed the catchment area, river network, river cross sections at various locations, water levels at various river streams, land-use land-cover classes, etc. required for the study. The hydrological analysis was done to identify the basin and sub-basin characteristics and determine water flows in each sub-basin for given rainfall in all five delineated basins. The validated hydrological models, with the help of HEC RAS and HEC HMS tools, were used to estimate runoffs from the river basins for all return period events. The historical rainfall was used to extract annual maximum rainfall for the study area, which was further processed to derive return period rainfall. Flood hazard maps depicting flood extents and flood depths were derived by performing one-dimensional hydraulic modeling through the river system for 2, 5, 10, 25, 50, and 100- years return period discharges."
