WaterWare Release Notes
RRM Rainfall-Runoff ModelRRMa is a dynamic (daily) rainfall-runoff and water budget model for sub-catchments.
The entry point is a selector of scenarios, which can be sorted and filtered by several properties such as name, author, modification date, or location.
Another option at the level of the scenario selection is the possibility
to create a new scenario with an empty template.
To facilitate and simplify the generation and editing of new scenarios,
it is also possible to copy an existing one and modify it incrementally under a new name.
Editing a scenario for the rainfall-runoff model involves four major components:
The model parameters are grouped into several sets:
Prior to running the model, all parameters are automatically checked for
completeness, consistency, and plausibility (see below).
A special set of parameters with a dedicated editor describes the basin orography, or area-elevation distribution.
For every 100 meter altitude layer, the user specifies the corresponding area.
While the model is spatially (horizontally) lumped, it is vertically distributed:
it uses the elevation distribution of the basin
to correct temperature and precipitation values varying with elevation,
and keeps track of snow and snow-melt where applicable.
Checking scenarios: attached to the editors for all models, a checking routine to check for
This routine can be triggered interactively, on demand,
or it is run automatically whenever the model should be run to ensure proper inputs
and thus meaningful model results.
On the main scenario page, the model results are shown as a time series of daily runoff.
Where specified, these data are shown together with the observed runoff data that can also be used for automatic model calibration.
The display shows the simulated runoff together with an (optional)
observation data set.
Together with the daily results, a monthly aggregate for the main variables:
Another output page (button: Details) shows several panels with individual variable over time. These include:
Yet another output page (button: Monthly ) shows a tabular summary of monthly water budget components, corresponding to the detailed time series above.
A final results page shows estimates of watershed erosion: sediment yield and average turbidity.
Inputs used are the simulated flow together with
