Software architecture


hms is an object-oriented scientific prototyping framework with a flexible and extendible component-based design. Information is stored in layers, whereby each layer represents a different physical process or geospatial data.

The numerics of hms are based on a cell-centered finite volume method. A robust high-order HLLC Riemann solver based scheme is used to solve the governing physical equations (Hou et al. 2013), whereby the main focus is on the depth-averaged shallow water flow and transport (dissolved components, sediments) equations.

Test cases
