Abstract:

EcoWin2000 is an ecological modelling system which is used to simulate changes in the water quality and ecology of rivers, lakes, estuaries and coastal waters. The system has been developed over the last 10 years, and runs on WindowsNT and Windows 95 or 98. The architecture of the system was described in detail in a paper published in the journal Ecological Modelling, which can be read here.

In brief, the system consists in a shell, which manages the input and output, and a set of "objects" which perform the calculations. The software is written in C++, and the model objects encapsulate different forcing functions and state variables, which may be turned on and off for a particular simulation. MS-ExcelTM is used as a platform between the model and the user, both for building the necessary input files to run a model and for generating output of results. User files are stored in native Excel97 format.

EcoWin2000 is used to build dynamic models, which may vary only with time (zero-D), or may vary also in space: longitudinally (one-D), in two dimensions ( two-D), or in layers (three-D).

It is not necessary to know how to program in order to use the system, providing you are exploring an existing model. This includes changing the system morphology and bathymetry, and making alterations to pollutant loads, or other system boundary conditions, and deciding what objects your model will use for its calculations.

However, it is necessary to be fluent in C++ in order to extend the functionality of a particular object - for instance you may be using a phytoplankton object in your model and decide to extend its properties to allow it to grow only when silica is present - i.e. to become a diatom. For that, you need to write a few lines of code.
