Initial Application of a Landscape Evolution Model

By To A Louisiana Wetland and Carl F. Cerco


PURPOSE: Corps planning projects encompass a wide variety of restoration goals. These include wetland restoration, island restoration, stream restoration, dam removal, and other projects which result in alteration of the landscape. Planners require tools to help predict potential outcomes of restoration efforts over periods spanning decades. This work unit in “Landscape Evolution Modeling ” is intended to acquire, employ, and develop, as necessary, Landscape Evolution Model (LEM) tools that can be used to forecast the evolution of the aquatic-land interface, thereby providing information that can be used to project future impacts and benefits. This technical note reports on the initial application of an LEM to Davis Pond, LA. The application examines the feasibility of transferring an existing LEM from the Florida Everglades, where it was developed, to a distinctly different system. BACKGROUND: A variety of LEM’s exists, one or more of which may fulfill the specified needs as well as serve additional purposes. The three-year planned program will survey a range of existing LEM’s for suitability and produce applications and an initial LEM for distribution and employment at the district level. In the first project year, one or more LEM’s will be acquired, installed on Corps computing platforms, and then be examined and applied. In th
