Development of an Inundation Mapping Capability Using High Resolution Finite Element Modelling.

Abstract

Since the previous report the long awaited topographic data for the Gavins Point to Maskell reach has now been received. The data consists of 343 cross sections of the river bed, on average the sections are spaced about every 150 meters and contain about 100 data points (depending on section length). With this data the model shall become fully operational for flow simulation in the next few weeks. It should also allow the stage data at Yankton and Gayville to be used for rigorous calibration as proposed in the previous report. The processes that have been necessary in applying the new topographic data to the model are outlined in this report as are the outstanding future steps and problems at this time. With both the model and the data based on the UTM (Universal Transverse Mercator) co-ordinate system a very close spatial match was apparent. This allowed the data to be directly applied to the model with only minor modifications necessary to the model boundaries and topographic cross sections.
