Storage routing models
(a) General As well as the standard Horton (ILSAX) hydrological model for simulating flows from urban areas, DRAINS has optional storage routing models based on procedures applied in three hydrological models that have been used in Australia since ...
Storage Routing Hydrological Model property sheet
This sheet appears when a storage routing model is selected in the Hydrological Model dialog box. It can take three forms, depending on the type of storage routing model selected. For a RORB type model it appears as shown below. A model name, initial ...
DRAINS Hydraulic Models
The following table sets out the differences between the two hydraulic models used in DRAINS: These differences have developed due to the way that DRAINS developed. Initially, flow depths and characteristics were calculated by a combination of ...
Hydrological model dialog box
From this window you can select the hydrological rainfall-runoff model to be used. The current default model selected for Designand Analysis runs is shown in the list box to the left. Clicking the Delete Default Model button deletes the highlighted ...
Basic hydraulic model (obsolete)
(a) Introduction This model, now obsolete, was the original hydraulic calculation procedure applied to pipe and open channel systems in DRAINS. In December 2010, this method was superseded by the Lite & Full Unsteady hydraulic models. It has been ...
