The Water Erosion Prediction Project (WEPP), is a physically-based soil erosion prediction technology. WEPP has a number of customized interfaces developed for common applications such as roads, managed forests, forests following wildfire, and rangelands. It also has a large database of cropland soils and vegetation scenarios. The WEPP model is a distributed parameter, continuous simulation model, and is able to describe a given erosion concern in great detail for an experienced user.
The WEPP model consists of multiple applications that can estimate erosion and sediment processes on hillslopes and small watersheds, taking into account climate, land use, site disturbances, vegetation, and soil properties.
Peatland ecosystems represent 3-5% of earth's land surface, but store 12-30% of soil organic carbon. However, this very large pool of carbon is vulnerable to loss to the atmosphere as CO2 because of climate change. Lowered water tables caused by climate change or human-caused drainage can shift peatlands from being net carbon sinks to net carbon sources. The PEATcosm experiment was initiated to study the relationships between water tables, plant communities, and carbon and nutrient cycling in peatlands in a controlled setting.

The largest terrestrial carbon pool is contained in soils. Carbon stored in soils plays a number of important roles, including keeping carbon out of the atmosphere and improving moisture and nutrient retention.
Eastern Forest Environmental Threat Assessment Center
Researchers are assessing the causal relationships between management regime or disturbance and the environmental controls of biosphere-atmosphere exchange of carbon and water. The overall objective is to measure and model the coupling effects of forest management and changing climate on carbon dioxide and water fluxes in eastern forests of the United States and China.
