ECOMAG Model: an evaluation for use in South Africa
Expanded Title:The Russian ECOMAG model has been suggested as a possible candidate for use in South Africa, and this aims to evaluate its suitability for use under South African conditions. In the abscence of the software code, the ECOMAG Model was evaluated qualitatively (without setting up and running it) against the South African equivalent models such as the Pitman and the ACRU. Naturally, each model is constructed to solve practical problems in a particular environment. The ECOMAG was developed specifically for the boreal environment, which is completely different from the South African environment. Thus, the main conclusions of this review were that (a) this model may not be set up and used in South Africa without fundamentally compromising internal conceptual integrity, (b) in terms of process representation and outputs, the ECOMAG is similar to the local models. Thus, it is unlikely that the ECOMAG model will add any value to water resources assessment, as the local models cover the most significant bases and their results have served the country well, (c) there is little available literature on the geochemical component of the ECOMAG model to make a value judgment. However, the ACRU model fulfils a practical need for water quality assessment using the ACRU-NPS, and (d) unlike the ECOMAG Model, the technical support for the Pitman and ACRU models is based in South Africa and thus making these models cost-effective. Therefore, if there is a real need for the ECOMAG model, based on the premise that there is a gap that it will fill, then it is imperative that it is practically evaluated in a number of catchments spanning the different geophysical and hydro-meteorological conditions obtaining in the country.
