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.
Lifecycle Phase(s): Operation and MaintenanceInfrastructure assets are managed and maintained during their use time.
Type(s) of Tool: Modelling ToolsSimulate economic, social, and physical systems to help planners optimize outcomes from different decisions.
