Long-Term Hydrologic Sustainability of Calcareous Fens Along Glacial Lake Agassiz Beach Ridges, Northwestern Mn
… fens are located in the Glacial Lake Agassiz beach ridge complex in northwestern Minnesota. Each of these fens is located immediately downslope of large sand/gravel beach ridges, where peat aprons have accumulated on the seepage face. This investigation characterizes the hydrology and …

Developing a rapid method for assessing the physical stability of streams in Minnesota's Agassiz beach ridges
… western Minnesota streams that cross the eastern beach ridges of glacial Lake Agassiz. Stream and river channels in this area host unusually diverse aquatic habitat and biodiversity, but incompatible land use along channels and in watersheds impair their quality and function. Previous rapid …

Time Scales and Processes of Shoreline Formation in Pluvial Lakes of the Great Basin, Western USA
This study examines historical beach deposits formed in Walker Lake, Winnemucca Lake, and Lake Tahoe to characterize the processes that lead to the construction of beach ridges along lacustrine shorelines and compares the volume of individual shoreline features to the lengths of time under which …

Pleistocene geology of the Comstock-Sebeka area, west-central Minnesota
… The district includes the complex network of beach ridges and wave-cut scarps that were developed at the margin of Lake Agassiz in Late Wisconsinan and Early Holocene time. The gently undulating to strongly rolling Glacial-Upland District is underlain by glacial and fluvial sediment that …

Hydrodynamic Controls on Sedimentology and Geomorphology of Marine-Carbonate Ramps: Insights from a Holocene Analogue, Northern Yucatán Shelf, Mexico
… Extensive shore-parallel sand bodies (beach ridges and subaqueous dune fields) of the high-energy upper shoreface and foreshore are composed of fine to coarse skeletal sand, lack mud, and includes highly abraded, broken and bored grains. The large shallow lagoon is also mixed energy, …

Questioning Commonplace Ecological Design: a study of waterfront design practices and the ecological well-being of development in the harbor of Oyster, Virginia
… down, the vegetative roll moves forward, the beach ridges reconfigure, and the tidal flats create a shelf that extends out into the ocean floor.This evolution of land continually cycles on moon and sun paths that dictate the change in light, shade, wind, tides, motion, and human cycles. …

Configuration of the Pleistocene Surface Beneath Cat Island, Mississippi and Implications for Barrier Island Formation and Evolution
… high-grounds of the Pleistocene surface. Beach ridge strandplain sets on Cat Island provide additional evidence supporting the island's formation over a relict depocenter. A new, 4-stage model for Cat Island development and evolution incorporating the influence of pre-existing topographic …
