Creation of Improved Accuracy LiDAR-Based Digital Elevation Models for the St. Jones River and Blackbird Creek Watersheds

In tidal wetlands, small differences in ground elevation can have a large impact on hydrology, vegetation, and habitat (e.g., assessment of wetland health and stability, habitat, flood risk, and coastal inundation).

RI34 Long-Term Chemical-Quality Changes in Selected Delaware Streams

Data from three streamflow water-quality stations were statistically analyzed to determine the relationships of the major inorganic chemical constituents to specific conductance and to stream discharge. The results show that ion concentrations varied directly with the flow and with specific conductance. A set of regression equations defining these relationships were derived for each of the three stations: Brandywine Creek at Wilmington, St. Jones River at Dover, and Nanticoke River near Bridgeville.
