Due to inadequate rainfall, groundwater has acquired a vital role in the development of Pakistan's agricultural economy. However, a lack of awareness concerning the use of groundwater, either by itself or combined with canal water, has added large amounts of salt to the soil. As a result, large tracts of irrigated lands are already salinized, while many others are under threat. This report presents the results of a modeling study carried out to evaluate the long-term effects of a different quality of irrigation water on root zone salinity. The simulations were performed for the Rechna Doab (sub basin of the Indus Basin) in Pakistan, by using 15 years of actual rainfall and climatic data.

This study provides a hydrology based assessment of (surface) water resources and its continuum of variability and change at different spatio-temporal scales in the semi‐arid Karkheh Basin, Iran, where water is scarce, competition among users is high and massive water resources development is under way. The study reveals that the ongoing allocation planning is not sustainable and essentially requires reformulation, with consideration of spatio‐temporal variability and observed trends in the streamflows regarding flood intensification and decline in low flows. The development of innovative methods for quantification of the hydrological fluxes (i.e., regionalization of model parameters based on similarity of the flow duration curve and the use of areal precipitation input in the hydrological modeling) helped better understanding and modeling the basin hydrology. The investigation of scenarios for upgrading rain-fed areas to irrigated agriculture, using SWAT, recommends the promotion of in-situ soil and water conservation techniques. Conversion of rain-fed areas to irrigation causes significant reduction in the downstream flows, and requires additional considerations such as less development in the upper catchments, practicing supplementary irrigation and developing water storage. The knowledge generated is instructive for hydrological assessment and its use in water resources planning and management in the river basin context.

Water Resources Management is a component of Encyclopedia of Water Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. This 2-volume set contains several chapters, each of size 5000-30000 words, with perspectives, applications and extensive illustrations. It carries state-of-the-art knowledge in the fields of Water Resources Management and presents an integrated water resources management, water and sustainable development, water scarcity, and the more technical aspects of water resources planning. Important issues related to international rivers, the economics of water, and the legal and institutional aspects of water are addressed. And new approaches to water conservation, non-waterborne sanitation, and economic valuation are presented. These two volumes are aimed at the following five major target audiences: University and College Students Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers, NGOs and GOs.

In order to provide water security in the twenty-first century, there is universal agreement that a continuation of current policies and extrapolation of trends is not an option. Also clear is that from both water supply and development perspectives, the world's arid and semi-arid regions are those currently and potentially experiencing the highest water stresses. One third of the world's land surface is classified as arid or semi-arid, and about half of all countries are directly affected in some way by problems of aridity. The hydrology of arid and semi-arid areas is also known to be substantially different from that in more humid regions. It is therefore essential that investigation methods appropriate to the former are developed and applied, and that strategies for arid and semi-arid region water resources development recognise the principal characteristics of in-situ hydrological processes.

Hydrology is a key influence on water security, environmental sustainability, agricultural production, energy, and transport, especially in unique environments such as arid regions and the tropics, where degradation issues on water and land can threaten the livelihoods of poor communities. With implications in urbanization, landscape architecture, and sanitation, enhancing the practice of water use, management, and planning is imperative for the sustainable development of these regions. Hydrology and Water Resources Management in Arid, Semi-Arid, and Tropical Regions is an essential research publication that seeks to improve scientific understanding and sharing of data in hydrology and integrated water resources management of arid, semi-arid, and tropical regions in order to enhance water governance and alleviate reduction in the vulnerability of water resources systems to global changes. Featuring a wide range of topics such as hydrometeorology, sustainable development, and climate change, this book is ideal for researchers, technology developers, academicians, policymakers, government officials, and students.
