Tools and Models

Using contemporary approaches and technology, for over seven decades, ICID has continuously taken initiatives to upgrade its ICT and related facilities to provide user-friendly access to the latest data, information, and knowledge products for the wider public. Some of the services that are being offered by the Central Office are briefly described here:


Basin-wide Holistic Integrated Water Management (BHIWA) Model is specially developed to provide an integrated computational framework for a basin level assessment of water resources with a view to evaluate water sector policies. The model considers the entire land phase of the hydrologic cycle and is capable of depicting human impacts such as changes in land and water use, as also impacts of water storage and depletion through withdrawals for various water uses and inter-basin water transfers. The model takes into consideration complex interaction between numerous factors including surface and groundwater, land use and natural water supply, storage and water withdrawals and returns, through separate water balances for surface and groundwater as well as an overall water balance.

The International Water Management Institute, as part of the World Water Vision 2025, has developed PODIUM - the policy dialogue model in 1999. The model, an interactive tool runs on a personal computer. The PODIUM enables the users to develop national-level scenarios of water and food supply and demand on various policy options. Though PODIUM was recognized as a useful tool for generating scenarios, some limitations were also identified. The PODIUM beta version was a cereal-based model [PodiumSIM (Zip file 2.21 MB)].

WEAP ("Water Evaluation And Planning" system) is a user-friendly software tool that takes an integrated approach to water resources planning. [More on WEAP....]


Download SALTMED 2019 (File size 398mb)

SALTMED model has been developed for generic applications. It accounts for different: irrigation systems, crops, soil types, and fertilizer applications. The SALTMED model (Ragab, 2002, 2005, 2009, 2015, 2019) was developed to predict dry matter and yield, soil salinity and soil moisture profiles, salinity leaching requirements and soil nitrogen dynamics and nitrate leaching, soil temperature, water uptake, evapotranspiration. The model is friendly and easy to use, benefiting from the WindowsTM environment; however, it is a physically-based model using the well-known water and solute transport, evapotranspiration, and water uptake equations.

Please carefully read the document: How to install the SALTMED model. You could also see the video on YouTube about installation and different parts of the model including problems and solutions. The User Guide has now been updated as well.
