The Mesopotamian Plain is part of the Mesopotamia which extends for vast area bigger than plain. plain almost flat and lowland, has clearly defined physiographic boundaries with other surrounding provinces. a huge accumulation geomorphologic unit, where fluvial, lacustrine, Aeolian landforms prevail; fluvial units being abundant among others. However, estuarine marine forms also are developed, ...

Rivers around the world are being regulated by dams to accommodate the needs of a rapidly growing global population. These regulatory efforts usually oppose the natural tendency of rivers to flood, move sediment, and migrate. Although an economic benefit, river regulation has come at unforeseen and unevaluated cumulative ecological costs. Historic and contemporary approaches to remedy environme...

The Ningxia Plain, situated in the arid zone of northwest China, is a typical dryland plain that faces significant challenges to sustainable agricultural development due soil salinization. In this study, we employed multivariate analysis and geostatistical methods investigate degree distribution types salinization hydrochemical characteristics shallow groundwater. We also examined relationship ...

Workflow of the multidisciplinary approach towards geogenic arsenic quantification in clay plug sediments. • Holocene fluvial geomorphology and permeability anisotropy control As-occurrence. Sediment bulk volume abandoned meandering-river bends ( plugs ) is calculated. Remote sensing, side-scan sonar sediment core analyses yielded total As-load. Microbial metabolism effectively controls As Fe f...
