Floodplain Management

This lecture discusses floodplains, their role during floods, and the impact of human activities on floodplain natural processes. It covers flood control measures, floodplain encroachments, and floodplain management strategies. The lecture also explores flood control alternatives, hydrologic analysis, and intensity-duration-frequency curves for rainfall. It delves into the determination of discharge, water stage, and damage analysis. Additionally, it examines the use of reservoirs for flood control, spillways, gates, weirs, and reservoir optimization. The analysis of discharge duration curves, exceedance frequency relationships, and the effects of reservoirs, raised levees, flood proofing, and channel modifications on flood management are also discussed.
