Flood Modeller is a full hydrodynamic simulator for modelling flows and levels in open channels and estuaries and is at the heart of the system. It is able to model complex looped and branched networks and is designed to provide a comprehensive range of methods for simulating flood plain flows. Flood Modeller incorporates both unsteady and steady flow solvers with options that include simple backwaters, flow routing and full unsteady simulation. The simulation engine provides a direct steady-state solver and adaptive time-stepping methods to optimise run-time and enhance model stability. It provides full interactive views of the model data and results using plan views, long sections, form based editing tools and time series plots. The software includes a wide range of diagnostic error checks. Maltby Surveys in association with our software development arm have incorporated into the RXS software package a direct export into Flood Modeller. Exporting in either 2D or 3D format makes the transition from field to hydraulic model very efficient. Full export to Environment Agency CDSF Version 3.31 has also been incorporated.
