Development of Regional Regression Equations to Estimate the Magnitude of Peak Flows for Selected Annual-Exceedance Probabilities in Maine

Knowledge of the magnitude and frequency of floods is needed for the effective and safe design of bridges, culverts, and other structures.  This information is also important for flood-plain planning and management. The flood-frequency characteristics for streamgages and regression equations for estimating flood magnitudes at ungaged sites were last developed in 1999 (Hodgkins, 1999).

Development of Regional Regression Equations in Connecticut

Knowledge of the magnitude and frequency of floods is needed for the effective and safe design of bridges, culverts, and other structures.  This information is also important for flood-plain planning and management. Periodic examination of flood-frequency characteristics is essential to ensure the best estimates of flood magnitudes for a given annual exceedance probabilities (AEP).

New Applications of Hyperspectral Imaging to Delineate Critical Minerals Concentrated in Regolith and Mine Waste Materials

Our project will develop new and innovative spectral methods and remote sensing tools for understanding how critical minerals are concentrated by weathering, regolith/soil formation, mining, runoff and ore processing. These tools will help us to use mineralogy derived from spectral measurements (lab, field, and remote sensing) to help delineate vectors towards recoverable resources and to...

Development of Methods Associated with Animal Population Dynamics

The Challenge: Conservation and management of natural animal populations requires knowledge of their dynamics and associated environmental and management influences. Specifically, informed management requires periodic estimates of system state (e.g., population size) and models for projecting consequences of management actions for subsequent state dynamics. However, it is very difficult to...
