Short summary
A levee-building model is presented to investigate the effects of flood on levee slope and river behaviors. Coarser grains that cause steep levee slopes lead to frequent switchings of river paths, but higher overflow velocity has an opposite effect. High levee slopes lead to more reoccupations of abandoned old river paths than low levee slopes when rivers switch their locations. The study helps us to assess flood hazards with river-path switching.
