Book Description
Written by renowned experts in the field, this book assesses the status of groundwater models and defines models and modeling needs in the 21st century. It reviews the state of the art in model development and application in regional groundwater management, unsaturated flow/multiphase flow and transport, island modeling, biological and virus transport, and fracture flow. Both deterministic and stochastic aspects of unsaturated flow and transport are covered. The book also introduces a unique assessment of models as analysis and management tools for groundwater resources. Topics covered include model vs. data uncertainty, accuracy of the dispersion/convection equation, protocols for model testing and validation, post-audit studies, and applying models to karst aquifers.

Book Description
This study, Indus basin of Pakistan: the impacts of climate risks on water and agriculture was undertaken at a pivotal time in the region. The weak summer monsoon in 2009 created drought conditions throughout the country. This followed an already tenuous situation for many rural households faced with high fuel and fertilizer costs and the impacts of rising global food prices. Then catastrophic monsoon flooding in 2010 affected over 20 million people, devastating their housing, infrastructure, and crops. Damages from this single flood event were estimated at US dollar 10 billion, half of which were losses in the agriculture sector. Notwithstanding the debate as to whether these observed extremes are evidence of climate change, an investigation is needed regarding the extent to which the country is resilient to these shocks. It is thus timely, if not critical, to focus on climate risks for water, agriculture, and food security in the Indus basin of Pakistan.

Book Description
Indus River Basin: Water Security and Sustainability provides a comprehensive treatment of water-related issues within the Indus River basin. Each chapter is written by an expert in the field, hence this book serves as a single, holistic source covering the whole region, not just a single country. Many of the challenges faced by this region are trans-boundary issues, especially within the context of climate change and water scarcity. Topics covered include extreme engineering and water resource management (one of the largest irrigation systems in dry to semi-desert conditions), social sciences (population dynamics linked to water resources) and political sciences. As such, this book is relevant and important to all researchers interested in these issues. - Includes detailed chapters provided by specialists in each different field as compiled by well experienced editors - Presents work from related fields across the Indus basin and makes them easily accessible on one single place - Shows the Indus River as a type case and shares issues relevant to other locations across the world

Book Description
The efficient use of water resources where both ground and surface water are used may require special policies to rationalize the interaction among pumping by farmers, canal diversions by irrigation system managers, and the physical response of the stream aquifer system. Significant gains in output are possible from more efficient conjunctive use. However, these potential gains are not costless because their realization requires changes in irrigation institutions, methods of irrigation management, and often accompanying investments in drainage facilities. Three broad approaches to the problem have been defined: (i) assignment of well-defined, transferrable legal property rights; (ii) imposition of corrective taxes or subsidies; and (iii) centralized control over the entire resource. The feasibility and institutional implications of these approaches are discussed and several case histories of actual policy responses to the social costs incurred by conjunctive use are reviewed. The prognosis is hopeful, but better information systems, more skilled managers, and institutional reforms are needed.
