Mohid SWAT

Two modified versions of SWAT were developed, based on the two SWAT releases (SWAT2000 and SWAT2005). The functionalities described herein are equal in both versions. So we refer to this modified versions in this paper has SWAT-MOHID. However, all the results showed here were obtained with SWAT2005 version. The aim of these developments is not to replace the use of SWAT graphical user interfaces for input or output, but to complement it. This also means that the developed outputs do not include all the SWAT variables but instead, they were developed on a need basis either for easier exploring, results analysis, model coupling, etc. This development benefits from many current developments and improvements of MOHID tools made by its users and will continue to benefit in the future. To make this development sustainable two important aspects were taken into account: i) the use of a source code version control software to keep track of changes made by many users in the code ii) the use of online discussion forum and wiki (using Wikipedia technology) that together allows the users to help each other and to participate in the documentation of the models and tools. One of the reasons to develop SWAT-MOHID was to compute nutrient loads onto surface water bodies (e.g. reservoirs, estuaries), using them has boundary conditions for models like MOHID Water and CeQualW2.
