Sedimentological and biogeochemical measurements were conducted on minerotrophic peat in a wilderness area granitic plateau to reconstruct the local ecosystem’s history clarify peat’s response global changes. The is less than 1900 years old. Its clay iron (Fe) concentration profiles revealed an increasing atmospheric influx over time, whereas levels of its nutrients (P, K, Ca, Mg) have increase...

Coastal erosion of sandy beaches is a global problem that threatens ecosystems and coastal communities. Beach nourishment one the commonly implemented mitigation strategies, using beach compatible sediment from various borrow sources placed on back in littoral system. However, geotechnical properties different can vary. Sediment characteristics influence post-nourishment equilibration, slope, s...

The high alpine valleys in the Southem Pyrenees are characterised by a many small lakes and ponds. They occur above 2000 m and are said to have been formed by glacial erosion. The sediments in these basins should, therefore, contain s t p tigraphic information since deglaciation, at least. An interesting and may be one of the most important of these basins is Lake Llauset in the Alta Ribagorca....

We analyzed the sedimentological characteristics and magnetic properties of cores from the three basins of Clear Lake, California, USA, to assess the depositional response to a series of land use changes that occurred in the watershed over the 20th century. Results indicate that distinct and abrupt shifts in particle size, magnetic concentration/mineralogy, and redox conditions occur concurrent...

A textural classification of sediments collected in input channels, shallow lagoon beds and navigation channels of the Lagoon of Venice is presented. Some variables describing both the hydrodynamics and the transport time scales of the Lagoon are compared with bottom sediment distribution inside the basin. A high correlation between residence time (REST) and the silt fraction (4-31 μm) was only...

We have studied the morphology and the morphometric relations between alluvial fans and drainage basins in a bajada system including more than 20 coalescent fans developed since the Late Pleistocene as a result of the recent uplift of the Sierra Nevada (Betic Cordillera, Spain). Three allocycles of tectonic origin were recognised across which there is a clear evolution from debris flow to sheet...
