In this book, climate change and digital transformation are explored as key strategic drivers for the contemporary practices of water utility companies. These drivers seem to be separate, but clearly, they are not. The recent weather anomalies in water stressed countries are discussed, which have been breaking records and become an elevated risk to water assets. In parallel, the book examines a contextual proposition that the concept of the fourth industrial revolution applied to the water sector, Water 4.0, assists with the water supply decentralisation and sustainability, in particular climate resilience. It further suggests that the implementation of an Asset Management System with reference to the ISO 55001 standard is a useful tool in this process.

Most complex physical phenomena can be described by nonlinear equations, specifically, differential equations. In water engineering, nonlinear differential equations play a vital role in modeling physical processes. Analytical solutions to strong nonlinear problems are not easily tractable, and existing techniques are problem-specific and applicable for specific types of equations. Exploring the concept of homotopy from topology, different kinds of homotopy-based methods have been proposed for analytically solving nonlinear differential equations, given by approximate series solutions. Homotopy-Based Methods in Water Engineering attempts to present the wide applicability of these methods to water engineering problems. It solves all kinds of nonlinear equations, namely algebraic/transcendental equations, ordinary differential equations (ODEs), systems of ODEs, partial differential equations (PDEs), systems of PDEs, and integro-differential equations using the homotopy-based methods. The content of the book deals with some selected problems of hydraulics of open-channel flow (with or without sediment transport), groundwater hydrology, surface-water hydrology, general Burger’s equation, and water quality. Features: Provides analytical treatments to some key problems in water engineering Describes the applicability of homotopy-based methods for solving nonlinear equations, particularly differential equations Compares different approaches in dealing with issues of nonlinearity

This book analyses how a water utility from a developing country, Phnom Penh Water Supply Authority, that was totally dysfunctional, corruption-ridden and literally bankrupt in 1993, became one of the most successful water utilities of the developing world in only about 15 years. By 2010, some of the performance indicators of this public sector utility were even better than London, Paris or Los Angeles. The book further analyses the enabling conditions that made this remarkable transformation possible. Based on this analysis, a framework is recommended for water utilities from developing countries so that they can also be transformed into functional, efficient, equitable and financially viable institutions on a sustainable basis.

Ever-increasing population growth has caused a proportional increased demand for water, and existing water sources are depleting day by day. Moreover, with the impact of climate change, the rates of rainfall in many regions have experienced a higher degree of variability. In many cities, government utilities have been struggling to maintain sufficient water for the residents and other users. The Handbook of Irrigation Hydrology and Management examines and analyzes irrigated ecosystems in which water storage, applications, or drainage volumes are artificially controlled in the landscape and the spatial domain of processes varies from micrometers to tens of kilometers, while the temporal domain spans from seconds to centuries. The continuum science of irrigation hydrology includes the surface, subsurface (unsaturated and groundwater systems), atmospheric, and plant subsystems. Further, the book includes coverage of environmental and economic impacts, water quality issues, water harvesting, satellite measurements for irrigation, and more. Features: Offers water-saving strategies to increase the judicious use of scarce water resources Presents strategies to maximize agricultural yield per unit of water used for different regions Compares irrigation methods to offset changing weather patterns and impacts of climate change

In an increasingly global community of researchers and practitioners, new technologies and communication means have made the transfer of policies from one country or region to another progressively more prevalent. There has been a lot of attention in the field of public administration paid to policy transfer and institutional transplantation. This book aims to create a better understanding of such transfers in the water management sector. These include the adoption of modern water management concepts, such as integrated water resources management and forms of water governance, which are strongly promoted and sometimes also imposed by various international organizations. Transfers also occur within the scope of development aid or for the purpose of creating business opportunities. In addition, many research organisations, consultancies and governmental agencies are involved in cross-border work. The purpose of this book is therefore to present practical examples of the transfer of modern water management from one locality to another and to critically discuss the transferability of policy and governance concepts by analysing the contextual needs and factors. Case studies are included from North America, Europe, the Middle East and Asia. It is argued that in many cases context matters in water management and that there is no panacea or universal concept that can be applied to all countries or regions with different political, economic, cultural and technological contexts. Yet it is also shown that some countries are facing pressing and similar water management issues that cut across national borders, and hence the transfer of knowledge may be beneficial.

This book highlights what are likely to be the future megatrends in the water sector and why and how they should be incorporated to improve water governance in the coming decades. In this first ever book on megatrends for the water sector, 22 leading world experts from different disciplines representing academia, business, government, national and international organisations discuss what the major megatrends of the future are and how they will radically change water governance in the coming decades.
