The ECOSIM groundwater quality model

For details of the model operation, assumption, coefficients etc., please consult the Groundwater Models description on the ECOSIM web pages.

In the Athens Demonstrator, the Groundwater Model is implemented with the following features and constraints:

Steady state simulation
One unconfined aquifer (limestone - dolomites)
All aquifer properties are isotropic and homogeneous

Please note that all static input data that are NOT edited by the ECOSIM interface, see below, are provided at the server side; this includes initial and boundary conditions of the model, and any dynamic forcing applied.

The Groundwater Model is implemented as a remote server through the http protocol.

The corresponding server URL is specified in the default file ./defaults/neco in the Athens Demonstrator version:

*.cliser.sernames.name.3:     Athens GW
*.cliser.sernames.node.3:     aix.meng.auth.gr/cgi-bin/mt3d

To modify the list of servers and potential alternates and backups, modeify the node name in the deafult file; when adding a server, please make sure to also update *.cliser.sernames.n accordingly.

Groundwater Model functionality

The basic functionality includes the following options:

editing and submitting new simulation requests; (the paramters that can be set are an initial concentration and the duration of the model run);
display of the scenario result (a single static image representing the situation at the end of the specifed run-time).
