Visualizing Ecosystem Land Management Assessments (VELMA) Model

VELMA can be used to help improve the water quality of streams, rivers, and estuaries by making better use of both natural and engineered green infrastructure. The tool is designed to help users assess green infrastructure options for controlling the fate and transport of water, nutrients, and toxics across multiple spatial and temporal scales for different ecoregions and present and future climates. VELMA also addresses green infrastructure maintenance and longevity to predict how once-effective riparian buffers can fail, depending upon contaminant loads, soil properties, changes in climate, and other factors.
