floodplain

: Impervious surfaces, vegetation cover. Hydrologic Modeling a. Selecting the Appropriate Rainfall-Runoff Model Rational Method: Suitable for small watersheds (less than 200 acres). SCS Curve Number Method: Widely used for larger watersheds. b. Calculating Runoff Rational Method F

lains: 1D Models: Focus on flow along a single dimension, ideal for river channels. 2D Models: Capture flow across terrains, essential for overbank flooding. Coupled 1D-2D Models: Combine both to simulate comple
