This book deals with environmental effects on both sides of the border between Bangladesh and India caused by the Ganges water diversion. This issue came to my attention in early 1976 when news media in Bangladesh and overseas, began publications of articles on the unilateral withdrawal of a huge quantity of water from the Ganges River through the commissioning of the Farakka Barrage in India. I first pursued the subject professionally in 1984 while working as a contributor for Bangladesh Today, Holiday and New Nation. During the next two decades, I followed the protracted hydro-political...

Design of water control structures, reservoir management, economic evaluation of flood protection projects, land use planning and management, flood insurance assessment, and other projects rely on knowledge of magnitude and frequency of floods. Often, estimation of floods is not easy because of lack of flood records at the target sites. Regional flood frequency analysis (RFFA) alleviates this problem by utilizing flood records pooled from other watersheds, which are similar to the watershed of the target site in flood characteristics.

Clustering techniques are used to identify...

During the past decade many countries in the world have experienced droughts, with severe impacts on water urban supply systems. Because droughts are natural phenomena, water utilities must design and implement drought management plans. This topic was selected for the International Course on Drought Management Planning in Water Supply Systems, which took place in Valencia, Spain, on 9-12 December 1997, and was hosted by the Universidad Internacional Menendez y Pelayo (UIMP).
The contributions in this book have been carefully selected and presented in four sections:

and Hydrogeology 1 INTRODUCTION TO HYDROGEOPHYSICS 12 SUSAN S. HUBBARD and YORAM RUBIN 1 Lawrence Berkeley National Laboratory, Earth Sciences Division, Berkeley, CA 94720 USA. sshubbard@lbl. gov 2 Department of Civil and Environmental Engineering, UC Berkeley, Berkeley, CA 94720, USA In this chapter, we discuss the need for improved hydrogeological characterization and monitoring approaches, and how that need has provided an impetus for the development of an area of research called hydrogeophysics. We briefly describe how this research area has evolved in recent years in response to the need...

The most powerful earthquake in 40 years occurred on 26th December 2004 off the west coast of Sumatra, Indonesia. The tsunami it generated turned into one of the worst known natural disasters when walls of water crashed across the Indian Ocean, causing waves to reach Somalia in Africa. The death toll, mainly in Indonesia and Sri Lanka, exceeded 200,000. Nine months later, hurricane Katrina devastated the southern coast of USA along the Gulf coast. Winds reached 281 kilometers per hour and the storm surge of over nine meters was the highest recorded in the United States. It brought destruction...

This book deals with the concept of moments, and how they find application in subsurface hydrologic problems-particularly those dealing with solute transport. Both temporal and spatial moments are dealt with in some detail for a wide variety of problems. Several examples using experimental data, both from laboratory columns and field experiments, are provided to give the readers a clear idea about the scope of this method.

Groundwater constitutes the most important reservoir of available clean water. Due to its overexploitation, some anthropogenic mismanagement on the surface and the overloading of the cleanup potential of subsurface, many of the groundwater systems used for water supply are in jeopardy. The problem is very severe in dry-lands, but also in urban, industrial, agricultural and traffic areas.

This book first addresses the recharge fluxes relating both to the quantity and quality of groundwater. In order to face the threats to the water supply and to be able to maintain a sustainable...

The progress that has recently been made in the field and applications of thermochemistry, having as a consequence an in- crease in the interest of the subject, undoubtedly can be con- sidered highly remarkable. Traditionally, the thermochemist has provided accurate ther- mal data on chemicaZ compounds of practicaZ importance, mainly by calorimetric and by equilibrium studies. The scope has been considerably extended in recent years, following the development of microcalorimetric techniques, of flow calorimetry, of titra- tion calorimetry, and of high temperature calorimetry. The im- pact has...

At last, integrated management of drought on farms is dealt with in one comprehensive book. Although drought is a highly variable, near-universal natural phenomenon which has repercussions on a country's water and food supplies and many other sectors of the economy, there are many ways of avoiding, resisting and mitigating the effects of drought. Pro-active preparedness entails using the principles of risk management to upgrade the drought resistance of a farm systematically, and to have auxiliary contingency plans at the ready for use during unusually long droughts. The book provides tools...
