The literature of hydrology abounds with texts on the hydrological and water resource problems in humid regions. However, this is not the case for the arid or semi arid regions. The situation is exemplified by the fact a concrete definition for the term wadi, as accepted by UNESCO for describing these areas, is difficult to find.

Arguably the first book devoted entirely to examining this important resource, Wadi Hydrology presents methodologies for sustainable management of wadis and their water resources. Through unique physical approaches, field cases, sample...

The purpose of this book is to present an overview of the latest research, policy, practitioner, academic and international thinking on water security-an issue that, like water governance a few years ago, has developed much policy awareness and momentum with a wide range of stakeholders. As a concept it is open to multiple interpretations, and the authors here set out the various approaches to the topic from different perspectives.

Key themes addressed include:

• Water security as a foreign policy issue
• The interconnected variables of water, food, and human...

This volume presents the contemporary issues surrounding groundwater pollution risk assessment and the application of vulnerability and risk assessment maps for the effective protection and management of aquifers. Numerous new and improved approaches to intrinsic and specific vulnerability assessment (modified DRASTIC, GOD, VULK, VURAAS) are described, some coupled with geophysical and hydrological surveys and hydrodynamic and transport modelling. Widespread use is made of GIS format.

Every year, natural disasters cause substantial loss of life and livelihoods globally, costing an estimated over $100 billion per year in the form of property loss and mobilization of emergency response personnel and equipment. It is critical to monitor, model and predict the risks of natural hazards in order to save lives, enhance societal resilience to natural hazards, and reduce economic losses. Modern technologies such as remote sensing, geographical information system, and high-performance computation have greatly propelled advances in the studies of natural hazards. Remote sensing,...
