What are the methods for flood routing through reservoirs and channels?

Flood routing tracks flood wave movement through systems. Reservoir routing: Modified Puls (storage indication) method uses continuity and storage-outflow relationship iteratively. Channel routing: Muskingum method uses storage = K[xI + (1-x)O], where K = storage constant, x = weighting factor (0-0.5). Muskingum-Cunge provides physical basis for parameters. Kinematic wave routing for overland flow. Hydraulic (dynamic) routing solves full Saint-Venant equations for detailed analysis. Choice depends on required accuracy and data availability.
