Morphology and Tidal Inundation of Tidal Wetlands in the Delaware Estuary

An expanse of tidal wetlands fringes the Delaware Estuary and provides Delaware, Pennsylvania, and New Jersey with abundant ecosystem services including habitat for indigenous and migrating plants and wildlife, biogeochemical cycling of nutrients, preserving water quality, flood hazard mitigation

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

Project Contact(s)
In tidal wetlands, the high density of vegetation cover inhibits penetration of LiDAR pulses through the vegetation to the ground surface and low vegetation heights inhibit classification of ground point elevations. This project identities and corrects for biases found in the St. Jones and Blackbird Reserves using GPS RTK surveying and statistical analysis.

SP28 Digital Elevation Model of Delaware

The Delaware Geological Survey led a multi-agency, state and federal effort (including DelDOT, DNREC, USGS, and NOAA) to secure funds from the Hurricane Sandy Relief appropriation to collect new, high-quality LiDAR for the entire state of Delaware. LiDAR, which stands for Light Detection and Ranging, is a remote sensing method that uses light in the form of a pulsed laser to measure distances from a source to a target object. Typically, a LiDAR device is attached to the bottom of a plane and is pointed at the ground.

Determination of Future Sea-Level Rise Planning Scenarios for Delaware

Project Contact(s)

The Delaware Geological Survey will review recent scientific literature and assessments of sea-level change in Delaware and identify appropriate scenarios to use for planning purposes throughout the state. This project will also develop new inundation maps along Delaware's coast that correspond to the identified scenarios.
