Content Inside: SHSG 2005 Catchment Modelling - Huband and Sene 1 INTEGRATED CATCHMENT MODELLING ISSUES FOR FLOW FORECASTING APPLICATIONS Marc Huband - Atkins Water1 Kevin Sene - Atkins Water2 Abstract Hydraulic models are increasingly used for real time forecasting applications such as flood forecasting water resource management and pollution control. This paper discusses some of the key initial modelling decisions to take in developing new models for real time use (or converting existing models). The topics discussed include the overall model design model configuration options real time updating issues and model run time and accuracy considerations. These issues are illustrated using the example of a complex real time model which was recently developed for the Welland and Glen catchment in Lincolnshire which incorporates more than 400km of real time hydraulic model reaches and almost 500 structures of various types. 1. Introduction Integrated catchment forecasting models can provide real time estimates of future levels and flows in a catchment and can be applied to a range of applications including flood forecasting water resource monitoring and management and pollution control. Their off- line counterparts which often form the basis for the real time version can also be used for other applications such as developing Catchment Flood Management Plans. With modern computing power it is increasingly practicable to develop complex real time hydraulic models for all significant river reaches and structures in a catchment which are capable of assimilating data from raingauges river gauges structures and other sources (e.g. weather radar) in real time and running within the typical telemetry polling interval of 15 minutes (in UK practice). However some modelling simplifications may be required and modelling effort tends to be focussed on key locations where forecasts are required (so-called Forecasting Points) with a more a ...
