changes in two shallow Danish lakes. Sediment cores have documented lake level changes as a result of long-term climatic changes during the Holocene period in deep lakes (Wolin, 1996, Abbott et al., 2000, Anderson et al., 2005). The lake level reconstructions were done through seismic surveys and changes in the diatom community.

The Importance of Water Level Changes and Shoreline ...

Water level fluctuations, whether climatically induced or the result of artificial regulation, can have a profound effect upon lake processes, especially in shallow lakes. Confounding the impact of changing water levels is nutrient input resulting from anthropogenic changes in land use. Paleolimnological techniques were used in a shallow seepage lake to infer the importance of water level ...

Effects of oil on the rate and trajectory of Louisiana ...

Nov 13, 2013 · The results suggest that there is a threshold where soil parameters change dramatically with a relatively small increase in oil concentration in the soil. Heavy oiling weakens the soil, creating a deeper undercut of the upper 50 cm of the marsh edge, and causing an accelerated rate of erosion that cascades along the shoreline.

Dramatic beach and nearshore morphological changes due to ...

Over 170 m of local shoreline (mean high water (MHW)) progradation was observed as a result of the flood, followed by 3 years of rapid local shoreline recession. During this post-flood stage, linear regression-determined shoreline change rates are up to −45 m a− 1 on the subaerial beach (MHW) and − 114 m a− 1 on the submarine delta (6 m ...
