ChannelLeveeModel: Decoupled Channel-levee Evolution Model for MATLAB

ChannelLeveeModel v1.0.1

This is the archive of a numerical model that decoupled channel bed and levee evolution with associated simulations, dataset, and figures using MATLAB

Features

Generate random weekly hydrographs and solve the divided channel method to compute the flooded water surface elevation (Lotter, 1933)

Identify two flood styles: Front loading and Back loading

Run advection-settling model (Han and Kim, 2022) for Front loading events and Ponded water model (Nicholas and Walling, 1996) for Back loading events

Visualizes results with MATLAB plotting functions
