Description
VELMA is a computer software model that helps improve the water quality of streams, rivers and estuaries by making better use of both natural and engineered green infrastructure that help reduce water pollution. The tool assesses different green infrastructure options for controlling the fate and transport of water, nutrients and toxics across multiple spatial and temporal scales, taking into account present and future climate scenarios. VELMA furthermore addresses longevity and maintenance issues for the identified solutions, depending on contaminant loads, soil properties and climatic changes.
Tool Outcome
The application of VELMA helps users to assess different green infrastructure solutions to improve water quality of streams, rivers and estuaries and identify possible tradeoffs through (comparative) modelling exercises and thereby facilitates decision making.
