The goal of this project was to model riparian wetlands in the Cache La Poudre watershed to provide a decision-support tool for monitoring change in the watershed following the devastating High Park Fire of 2012.

Currently, the swamp hydrology is managed by a system of canals and water control structures that are capable of maintaining or raising the water level within the swamp. Through the use of NASA Earth Observation System (EOS), we will provide a hydrological analysis of the entire swamp, depicting areas vulnerable to drying or inundation.

The DEVELOP team at Marshall Space Flight Center worked to help improve methods for controlling aquatic vegetation in North Alabama. Using Landsat 7 ETM+ and vegetation indices, the team created a method to map aquatic vegetation and points of agricultural source pollution.
