JFLOW: a multiscale two‐dimensional dynamic flood model

Abstract

Abstract A multiscale two‐dimensional (2D) dynamic flood model, known as JFLOW, has been developed by JBA Consulting for simulation of overland flooding. This paper first describes the background to the model development before explaining its technical basis. The model is based on a 2D diffusion wave equation and the computational engine has been linked with a geographic information system interface to provide a stand‐alone product. It has been applied on a variety of different scales which are illustrated in a number of example applications.
