Science and integrated drainage basin-coastal management:the Chesapeake Bay and the Mississippi Delta.
For decades, alluvial plains have been the areas of the fastest population growth over most of the globe. Modern societies demand growing extensions of flat and easily accessible land to accommodate t...
In a complex watershed, isolated wetlands, riparian wetlands and riparian buffers provide important functions such as flood attenuation and water quality improvement. For conservation purposes, it is ...

Each summer, Greenland’s ice sheet — the world’s second-largest expanse of ice, measuring three times the size of Texas — begins to melt. Pockets of melting ice form hundreds of large, “supraglacial” ...
Acid mine drainage (AMD) is an acidic, iron-rich leachate that causes the dissolution of metals. It constitutes a worldwide problem of environmental contamination detrimental to aquatic life and water...
The primary objective of this research involves mapping out and validating the existence of sub surface drainage tiles in a given cropland using Remote Sensing and GIS methodologies. The process is de...

A major emphasis in geomorphology over the past several decades has been on the development of quantitative physiographic methods to describe the evolution and behavior of surface drainage network...
An attempt has been made to study drainage morphometry of Manchi basin, which covers an area of 235.67 km2.Drainage Map prepared from Survey of India (SOI) toposheet and later updated from IRS-1C (LIS...

Wetland Drainage Effects on Prairie Water Quality。
Abstract: We derive a boundary layer equation describing accumulation regions within a thin-film approximation framework where gravity and surface tension balance. As part of the analysis of this prob...
Changes in land use and land cover (LULC) in the drainage basin of Lake Malawi over the period 1982-2005 were estimated from satellite imagery, and possible relationships were evaluated among the four...
Based on practice road tunnel engineering in Gansu province and near areas in west china, the main construction technology and emphasis of quality monitoring of waterproof and drainage of loess road t...
The availability of both global and regional elevation datasets acquired by modern remote sensing technologies provides an opportunity to significantly improve the accuracy of stream mapping, especial...
We present velocity observations of a glacier outlet in Vatnajökull, Iceland, deduced from interferometric SAR (InSAR) data obtained during the ERS1/2 tandem mission in 1995–2000. More than a 50%...
