Plant taxa identified in 90 U.S. Great Lakes coastal emergent wetlands were evaluated as indicators of physical environment. Canonical correspondence analysis using the 40 most common taxa showed that water depth and tussock height explained the greatest amount of species-environment interaction among ten environmental factors measured as continuous variables (water depth, tussock height, latit...

High resolution TerraSAR-X/TanDEM-X as well as Sentinel-1 remote sensing Synthetic Aperture Radar (SAR) data are used to determine and monitor the waterline in the Wadden Sea. In this very unique and dynamic coastal region in the southeastern North Sea, tidal flats extend several kilometers away from the coast during low tide with features like tidal inlets and sand banks. Under the influence o...

Laboratory experiments were performed in the wave flume of Laboratorio di Idraulica e Costruzioni Marittime Università Politecnica delle Marche (Ancona, Italy) to study hydrodynamic performance coastal protection structures made a new type geotextile sand containers (GSCs). Such are used as softer and flexible alternatives traditional hard defenses concrete or rubble mound material. The GSC can...

AIMS The Escherichia coli burden at a Great Lakes urban beach was evaluated during the summer months to determine if sand served as a reservoir for E. coli, and if there was evidence of cell replication in situ. Field and laboratory studies investigated the effects of moisture, temperature and UV on E. coli densities in the sand. METHODS AND RESULTS Sand samples (n = 481) were collected acros...

This paper is a case history of coastal development in Camp Ellis, Saco, Maine. It begins in 1867 with dredging and jetty construction at the mouth of the Saco River to facilitate commercial navigation. Beach accretion resulting from tidal delta collapse was developed with residences before its ephemeral nature was recognized. Misunderstanding of the riverine source of beach sand and the net, n...

The coastal marine ecosystem near the Elwha River was altered by a massive sediment influx-over 10 million tonnes-during the staged three-year removal of two hydropower dams. We used time series of bathymetry, substrate grain size, remotely sensed turbidity, scuba dive surveys, and towed video observations collected before and during dam removal to assess responses of the nearshore subtidal com...
