Rural catchment at Shepparton, Victoria, modelled using RORB hydrology
The file for this example, Shepparton RORB Rural.drn, is located in the folder C:\ProgramData\Drains among the Lite examples. If this folder is hidden, in File Explorer select the View tab and tick the Show Hidden Items box to make it visible.
This model is set up for an entirely rural catchment using the RORB type of storage routing model. The hydrological model and sub-catchment data entry are different to those for Horton (ILSAX) models. Some data is entered in the sub-catchments and some in the stream reaches. Reaches do not have levels specified. They only route flows and hydraulic grade levels are not provided. Detention basins can be added, and the model can be linked to open channels that provide full information on hydraulic characteristics.
When the model runs, it produces hydrographs as shown below, and indicates clearly the degree of flow routing that takes place in each reach. The red numbers are the peaks of the inflow and outflow hydrographs for each stream reach in m3/s, in the selected upper median or mean storm.
The standard method files also include variations on this Shepparton model using RAFTS and WBNM hydrology in files Shepparton RAFTS Rural.drn and Shepparton WBNM Rural.drn.
