One of the main objectives of hydrology is to quantify the fluxes of water and associated materials into and out of a watershed. To achieve this, measurements have to be made in a boundary zone between the watershed and an adjacent body, where that body could be the atmosphere, the groundwater system, the coastal zone, or even another watershed. However, each boundary zone is subject to a unique set of processes that have to be understood before accurate watershed flux estimates can be determined. Also, different processes may play a role in watershed-estuary interactions at different time scales. My research has focuses on such processes over a range of time scales in one particular type of coastal boundary zone- the tidal freshwater portion of estuaries. Prior to 1993 I did some work on coastal salt marshes in Long Island Sound, but the majority of my research into watershed-estuary interactions was carried out 1993-1998 in Chesapeake Bay.
