holocene in southwest khuzestan is represented by a fluvio-tidal succession termed thebahmanshir series which consists of two clayey layers separated by silty sand to silt beds. this paperdescribes the geotechnical properties of the clayey layers that have wide exposure in the lowlands of thepersian gulf coast. studied layers are generally clay sized and consist of a lesser percentage of clay m...

Groundwater arsenic (As) presents a public health risk of great magnitude in densely populated Asian delta regions, most acutely in the Bengal Basin (West Bengal, India and Bangladesh). Research has focussed on the sources, mobilization, and heterogeneity of groundwater As, but a consistent explanation of As distribution from local to basin scale remains elusive. We show for the Bengal Aquifer ...

An analytical solution for three-dimensional (3D) flow in the storative semiconfining layers of a leaky aquifer fully penetrated by a production well is developed in this article to provide a method from which accurate hydraulic parameters in the semiconfining layers can be derived from aquifer test data. The analysis of synthetic aquifer test data with the 3D analytical solution in the semicon...

Three representative nonsteroidal anti-inflammatory drug molecules, Ibuprofen, Diclofenac, and Indomethacin, have been intercalated within the galleries of an anionic clay, Mg-Al layered double hydroxide (LDH). X-ray diffraction, IR and Raman vibrational spectroscopy and (13)C cross-polarization magic-angle spinning NMR have been used to characterize the confined drug molecules, while molecular...

Abstract Groundwater basins in Bandung city are included the category of vulnerable areas to damage. It is interpreted that area has damaged groundwater conditions. Geological conditions and soil its surroundings consist alluvial layers eruption Mount Tangkuban Perahu. The type material north generally a andosol. In south east consists distribution species with clay deposits andosol types scatt...
