High-Tech Tools To Study Chesapeake Bay Watershed
Features in the landscape, such as urban development, agriculture, wetlands, and forests, can affect the water quality of a watershed. However, determining the role and the extent of each of these land uses is challenging, especially when the watershed is multi-use, as is the case for many watersheds.
Agricultural Research Service (ARS) scientists in the Hydrology and Remote Sensing Laboratory (HRSL) and the Sustainable Agricultural Systems Laboratory (SASL) have developed several new techniques to examine the contributions of nutrients from agricultural lands. This information will be used to examine the effectiveness of conservation practices and to make better predictions about how land-use changes will influence water quality in the Lower Chesapeake Bay. This work is part of the Long-Term Agroecosystem Research Network, which was created by ARS to study environmentally important watersheds, such as the Lower Chesapeake Bay. – By Peggy Greb, ARS Office of Communications.
