Introduction
eWater source is a fully-featured hydrological, water balance and water quality tool for use in integrated water
resource management. The model incorporates a rainfall-runoff model (based on land use) and a streamflow model
(incorporating nodes and links). Nodes are specific points along the river where water can be added, extracted,
stored or recorded such as for water demand, storage and water usage. Links store or route water and
constituents between nodes. eWater Source can be applied for water governance and allocation decisions, ,
environmental demands, and reservoir and release decisions. Key features of the eWater source model include the
ability to develop a watershed model using a schematic view of the watershed, and the ability to process
geospatial data. The software has multiple methods to model rainfall-runoff, constituent modeling and filtering
modeling. In addition, the program is openMI complaint and can be linked with third party software. The paid
version performs relatively more tasks compared to the free version.
