Scientists at NASA Ames have created a new computer model to simulate the growth and decay of floating aquatic invasive plants, such as water hyacinth and water primrose, on Delta waterways. The model is used to estimate biomass levels throughout the year. DRAAWP investigators Christopher Potter and Vanessa Genovese are developing the model within a mapping application (or GIS program) to extend the invasive species coverage area to the entire Bay and Delta. The growth of these species is controlled in the model primarily by temperature, salinity, water flow rates, and water nutrient contents.

This project is conducted in collaboration with the Delta Region Areawide Aquatic Weed Project (DRAAWP).

Christopher Potter is a Senior Research Scientist at NASA Ames Research Center.
