New Instrumentation for Water Budget Evaluation

Project Contact(s)

The Delaware Environmental Observation System (DEOS) and the Delaware Geological Survey have acquired and installed new instrumentation to measure evapotranspiration (ET). The eddy covariance (EC) instrument system, purchased with support from the Department of Natural Resources and Environmental Control, will improve the ability to quantify ET during agricultural and water supply drought periods and improve water availability estimates for resource managers.

New Instrumentation for Water Budget Evaluation

Date

The Delaware Environmental Observation System (DEOS) and the Delaware Geological Survey have recently acquired new instrumentation to measure evapotranspiration (ET). The purchase of an eddy covariance instrument, partially supported by the Department of Natural Resources and Environmental Control, will improve the ability to quantify ET during agricultural and water supply drought periods and improve water availability estimates for resource managers.

DGS releases new geologic map of Rehoboth Beach area

Date

The Delaware Geological Survey (DGS) has published a new geologic map of the Rehoboth Beach area in eastern Sussex County entitled Geologic Map of the Fairmount and Rehoboth Beach Quadrangles, Delaware. Geologic Map 16 presents the results of research by Kelvin W. Ramsey of the DGS.

GM16 Geologic Map of the Fairmount and Rehoboth Beach Quadrangles, Delaware

The geologic history of the surficial units of the Fairmount and Rehoboth Beach quadrangles is that of deposition of the Beaverdam Formation and its subsequent modification by erosion and deposition related to sea-level fluctuations during the Pleistocene. The geology reflects this complex history both onshore, in Rehoboth Bay, and offshore. Erosion during the late Pleistocene sea-level low stand and ongoing deposition offshore and in Rehoboth Bay during the Holocene rise in sea level represent the last of several cycles of erosion and deposition.
