WEAP for freshwater

Anyone who works in the fields of natural resources, environmental sustainability, or climate adaptation is likely to be familiar with the acronym IWRM — meaning Integrated Water Resource Management.   If that acronym actually describes their work, they are probably getting to know a newer one: WEAP the name of a software tool  for Water Evaluation And Planning.  This tool is especially useful for NGOs, agencies, and planners in the developing world where IWRM has become a cornerstone for healthy economic growth and community well being.

The creator of WEAP – the Stockholm Environmental Institute (SEI) – recently introduced version 3.0 of the software, which was developed by its US center based at Tufts University near Boston.  The great virtue of the software is that it encompasses much of the current practice and know-how of IWRM practitioners around the globe.

SEI describes WEAP as “a laboratory for examining alternative water development and management strategies.”   As such, it is a functional and versatile addition to the toolbox of models, databases, spreadsheets and even other software systems currently in use worldwide.

The software now has three operational modes:

  • A water balance database for maintaining water demand and supply information.
  • A scenario generation tool for simulating water demand, supply, runoff, streamflows, storage, pollution generation, treatment and discharge and instream water quality.
  • A policy analysis tool that evaluates water development and management options, and takes account of multiple and competing uses of water systems.

SEI has a licensing arrangement by which organizations in developing countries can obtain and use the software at no cost, supported by a progressive fee structure for individuals, institutions, and companies in higher-income nations. That certainly seems fair to this writer.

The WEAP site includes excellent tutorials and educational materials.  A trial version is also available.  To access all of this, you do need to sign up for the site’s WEAP Forum, but that shouldn’t be an issue for any professional involved in the conservation and management of the planet’s vital freshwater resources.
