RRM model implementation
RRM as part of WaterWare is a fully web-based client-server implementation.
Clients can be any device that can run any one of tyhe common industr standard web browser
a WaterWare web server).
- Model scenarios and their data are stored in the data base;
interactive editors and an automatic calibration tools are provided to define these parameters
and input data files. Please note that RRM is designed to operate with a minimum of "field data",
even for the calibration. The model represents on spatially homogeneous
(but vertically distributed) HRU (hydrological response unit);
Any number of such HRUs can be connected using the WRM topogical network structure
and network (nodes and reaches) editors.
- Model input time series are user selected and read from the data base (ModelTS);
- Model output is stored in an RRM specific data base;
- Flow result from a scenario can be exported to the ModelTS data base to be
re-used (copied) by the WRM water resources model.
- Scenarios can be shared/exchanged between the basic interactive model and
the automatic calibration tool (available as web version only).
- Whenever the model is ready to run (the run button is green),
the system first runs an automatic checking program to test
the completeness, consistency, and plausibility of the scenario data.
If no fatal error are encountered, the model is run (leading to the highlighting of the
vire results button; if error are encountered that make a succsessful model run
impossible, the error report from the checking program is displayed instead.
The Rainfall-Runoff Model input data
The data required are fully defined through the scenario editors,
starting with the basic scenario descriprion and its meta data;
In addition to the different parameter sets
the model requires daily input time series for one year at a time for
- Basin parameters
- Basin geometry and land cover/land use;
- Model parameters
- Model constants (should not require editing),
Optionally, an observed runoff time series can be used for visual comparison
between model results and observations (mandatory for the calibration version).
- precipitation (mm)
- average air temperature (degree Centigrade)
Please note that these time series can directly be imported to the web application
through an import dialog.
