Climate change is an accepted reality, so most infrastructure development and maintenance will require the evaluation of possible impacts of climate change.
Sediment resuspension occurs in harbors across the world as a function of propeller-induced water velocities, and resulting shear stress, at the sediment-water interface. While such events occur with….
The warm waters and shallow, vegetated waterways of the Gulf of Mexico provide valuable habitat to a diverse range of plants and animals….
The US EPA describes nutrient pollution as “one of America’s most widespread, costly and challenging environmental problems.” This issue is of significant concern world-wide, with considerable resources now being committed in Asia and Europe to study eutrophication in streams, rivers, lakes, bays and coastal waters and related economic, environmental and human health issues.
The need for detailed plans describing the restoration of impaired waters is widely recognized in developed countries. TMDL studies outline the maximum amount of a pollutant a body of water can receive without violating water quality standards, and an allocation of that amount to the pollutant’s sources. Determining the Wasteload Allocation, the portion of a receiving water’s assimilative capacity that is allocated to one of its existing or future point sources of pollution, is often required in a TMDL study. Numerical modeling is an indispensable component of these studies.
