[1] Quaternary alluvial fans have diverse surface morphologies related to both depositional and weathering processes. Numerous studies have demonstrated that the surface expression and morphometry of alluvial fans can be used as an indicator of their relative age of deposition, but only recently has there been an effort to utilize high-resolution topographic data to differentiate alluvial fans ...

The areas marked Quaternary Alluvium are areas underlain by unconsolidated gravel, sand, and silt sediments deposited by streams over the last 2.6 million years. The area marked Franciscan Formation is underlain by solid sedimentary, igneous, and metamorphic rocks that are over 65 million years old. Most alluvium is Quaternary in age and is often referred to as "cover" because these sediments obscure the underlying bedrock. Most sedimentary material that fills a basin ("basin fill") that is not lithified is typically lumped together as "alluvial". [9] Alluvium of Pliocene age occurs, for example, in parts of Idaho. [10] The Late Quaternary Alluvial and Soil Stratigraphy Comprehensive studies of late Quaternary sedimentation in Greece are still rare. Instead, the subject has been dominated by the view of Vita-Finzi (1969), vigorously supported by Bintli1975, 1977), that there were only two late Quaternary alluviations, the Older and the Younger Fill.

Sixty groundwater samples were collected from bore wells (hand pumps) in and around Bhalswa municipal solid waste disposal site, New Delhi, during May 2013 (Premonsoon N = 30) and November 2013 (Postmonsoon N = 30).

This pdf document provides an overview of the ground water quality in Arkansas, based on the 2013 Arkansas Water Plan. It covers topics such as water quality standards, monitoring programs, sources of contamination, and protection strategies. It also includes maps and tables showing the spatial and temporal variations of water quality parameters in different aquifers. Alluvium. Alluvium is a general term for clay, silt, sand and gravel. It is the unconsolidated detrital material deposited by a river, stream or other body of running water as a sorted or semi-sorted sediment in the bed of the stream or on its floodplain or delta, or as a cone or fan at the base of a mountain slope.
