New Revised versions of MWSWAT, MWSWAT 2009 and MWSWAT 2012 are now available. These work with the latest version 4.8.8 of MapWindow. MWSWAT 2012 uses the latest released version 622 of SWAT, and version 2012.10.0.14 of the SWAT Editor (which you will also need to install). MWSWAT and MWSWAT 2009 use the same versions of SWAT and the SWAT editor as their previous releases. Added to all variants is the ability to use the global weather data available from the SWAT website, including a special program for detecting and compensating for missing dates in the data.

Details of how to use the global weater data are included in the revised MWSWAT tutorial.

Watershed delineation is done with TauDEM version 5.1.2, which can use multiple processes on multicore machines to speed up processing. If you want to use multiple processes, and especially if you were doing this with the previous version using MPICH2, please read the notes on TauDEM version 5.1.2. This new version replaces MPICH2 with MS-MPI from Microsoft, which is easier to install.

The MWSWAT installers (in all variants) will replace, in addition to MWSWAT itself, the watershed delineation plugin and the MapWinGeoProc module of MapWindow. We are doing this to make use of new features before they are released by a new version of MapWindow. You should be aware of the following:

64-bit Please install the 32-bit version of MapWindow: MWSWAT, MWSWAT 2009 and MWSWAT 2012 are currently incompatible with the 64-bit version. But note that the MWSWAT installers (all variants) install the 64-bit version of the TauDEM executables when installed on a 64-bit machine: they run faster than the 32-bit executables.

MWAGNPS will not run on a 64-bit machine.

WaterBase

The WaterBase project is an ongoing project of the United Nations University hosted by UNU-INWEH. Its aim is to advance the practice of Integrated Water Resources Management (IWRM) in developing countries.

Predictive modelling and decision support for water management in developing countries are plagued with a number of related problems: lack of money, lack of expertise, inadequate training capacity, dependence on experts from other countries. At the same time water resources are under increasing pressure, and aquatic ecosystems are being damaged by people who lack the resources to explore the consequences of decisions before they are made.

The WaterBase project aims to provide
