The ERDC Environmental Laboratory has developed several simulation models that managers of aquatic and terrestrial systems can use to assess the biomass dynamics of plants. Currently four models for submersed plants are available (hydrilla, Eurasian watermilfoil, American wildcelery, and Sago pondweed). These models are all based on carbon flow through the vegetation in a meter-squared water column. The models include descriptions of several factors that affect biomass dynamics, such as site-characteristic changes in climate, water temperature, water transparency, water level, pH, wintering strategies, mechanical control, and climate. The user can easily modify the plant community and site characteristics. Reports, user manuals, and executables can be downloaded via the Internet at: http://el.erdc.usace.army.mil/products.cfm?Topic=model&Type=aquatic. |
