HEC-RAS Subgrid Bathymetry Theory and Application

Mark Forest is one of the most knowledgeable H&H modelers I know.  He’s also a very experienced RAS modeler.  Here he discusses the benefits of the relatively unique subgrid bathymetric approach to terrain surface discretization that HEC-RAS uses, specifically on the topic of computational mesh cell size.  Read this.  Then read it again.  This is […]
