A Study Of The Correlation Of Sub-Aqueous Beach Profile Change And The Coastal Storm Impulse (Cosi) Parameter, Kevin Bryan Conner

Civil & Environmental Engineering Theses & Dissertations

The Coastal Storm Impulse (COSI) parameter is a recently developed storm-strength parameter that was first introduced at the San Diego, California International Conference of Coastal Engineering in 2006 (ICCE) and further examined in 2008 at the ICCE in Hamburg, Germany. This new parameter used the principles of conservation of horizontal momentum to combine storm characteristics such as surge, wave dynamics, currents, and duration into a relative scale used to classify and measure storm response and impacts. The resultant classification system was intended to evaluate potential coastal erosion and the associated loss of coastal infrastructure, as well as provide a storm …

The Effects Of Offshore Mining Of Beach Quality Sediments On Nearshore Wave Climate, Frank R. Lonza

Civil & Environmental Engineering Theses & Dissertations

Coastal communities rely on the beaches to attract tourism, but these sources of revenue require maintenance, such as beach nourishment. In an effort to maintain these beaches without causing any detrimental results, research is conducted to determine what effects, if any, exist when mining for sand in offshore areas.

The U.S. Government is permitting the search for beach quality sands offshore but is also ensuring that such mining will not have adverse results to the nearshore wave climate. This study was conducted using a coarse grid bathymetric map to calibrate a numerical model developed by the Danish Hydraulic Institute (DHI). …
