waterway topo-bathymetry Garcia, Marcelo H. Takahashi, Roberto Hiroshi 2016-11-10T18:35:36Z 2016-11-10T18:35:36Z 2018-11-11T10:15:36Z 2016-07-22 2016-08 A steady 1D hydraulic model (HEC-RAS) was implemented for the Middle Paraguay River Basin (MPRB), which comprises a reach between Porto Murtinho, Brazil, and Asunción, Paraguay. In order to prepare the model, first the topo-bathymetry was prepared by digitizing more than 10,000 depth points from available nautical charts and scaling them to a consistent geographic reference system. The main features such as the cross sections, river reach length, flow path and ineffective flow areas were created with the aid of HEC-GeoRAS and imported to HEC-RAS to create the geometry file. A hydrological statistical analysis was conducted to prepare the input design flows from data that corresponds to Porto Murtinho and Asunción fluvial stations. Finally, the finished model comprises a river reach of approximately 635 kilometers, more than 200 cross sections with 3,100 meters of spacing, and calibrated Manning's n value of 0.0245 for the main channel and a value of 0.04 for the floodplain. The simulation results, such as the water surface profiles, were processed by HEC-GeoRAS in ArcGIS to prepare floodplain maps for the entire reach.
