Salinity and Tides in Alluvial Estuaries
The book describes an integrated theory that links estuary shape to tidal hydraulics, tidal mixing and salt intrusion. The shape of an alluvial estuary is characterised by exponentially varying width and the absence of bottom slope. This topography is closely related to tidal parameters, hydraulic parameters and parameters that describe 1-dimensional mixing and salt intrusion. Starting from the fundamental equations for conservation of mass and momentum, analytical equations are derived that relate the topography to tidal parameters (tidal excursion, phase lag, tidal damping, tidal amplification), wave celerity, lateral and vertical mixing and salt intrusion. The book presents a review of th...
Balancing Water for Humans and Nature
Balancing Water for Humans and Nature, authored by two of the world's leading experts on water management, examines water flows - the 'blood stream' of both nature and society - in terms of the crucial links, balances, conflicts and trade-offs between human and environmental needs. The authors argue that a sustainable future depends fundamentally on our ability to manage these trade-offs and encourage long-term resilience. They advocate an ecohydrological approach to land/water/environmental problems and advance a strong, reasoned argument for viewing precipitation as the gross fresh water resource, ultimately responsible for sustaining all terrestrial and aquatic ecosystem services. This bo...
Salt Intrusion, Tides and Mixing in Multi-Channel Estuaries
Multi-channel estuaries, such as the Mekong Delta in Vietnam and the Scheldt in the Netherlands, have characteristics of both the river and the sea, forming an environment influenced by tidal movements of the sea and freshwater flow of the river. This study discusses a predictive analytical approach for salinity intrusion and discharge estimate in multi-channel estuaries. The new approach agrees with 1-D hydrodynamic models and observations, indicating its applicability in practice. It has successfully developed a new theory and a new equation to quantify tidal pumping due to ebb-flood channel residual circulation and the related salt dispersion.
Water Resilience for Human Prosperity
A new approach to water-resources for researchers, professionals and graduate students, focusing on global sustainability and socio-ecological resilience to change.
Playing the Water Dance
Water is the thread that connects us all. The capable student of water management must have the ability to clearly and concisely ask the right questions, formulate an actionable research plan, expeditiously carry out the research, and disseminate findings so that they may be applied directly, adapted to suit particular needs and cases, and/or debated vigorously in the public domain. To this end, Playing the Water Dance serves as a timely and useful tool for the postgraduate student, mid-career academic, skilled practitioner, and seasoned consultant alike.
Modelling Interception and Transpiration at Monthly Time Steps
The book presents improved equations for monthly water resources models, in particular for interception and transpiration. Most of the existing monthly models do not make a distinction between interception and transipiration, while this distinction is very important for management purposes. Interception is direct feedback to the atmosphere, important to sustain rainfall. Transpiration is a good indicator for plant growth and biomass production. This distinction also contributes to the estimation of recharge and therewith of runoff.;The derivations are based on the Markov theory for the occurrence of rain-days. The methodology can be used on the basis of an analysis of a few time series of daily data, at a spatial scale of 300km and not necessarily of the same period as the monthly data. Zimbabwe served as the case study, but derived equations can be used worldwide as long as the relationship between the monthly rainfall and the mean number of rain-days can be established.
Water, Food and Welfare
This book addresses the following topics: the contemporary model for water management and alternative approaches; the socioeconomic framework, water policy and institutions; water use for food purposes, water-resources inventory and irrigation; manifestations of welfare loss and water prices; change in dietary patterns and water security; hydrological stress and pressures on water availability; groundwater management problems; vulnerability and climate change; water demand of major crops; gray water footprint and water pollution; gray water footprint and mining; virtual water and food trade; estimates of the water footprint of four key cereals, forage, livestock and bottled drinks. It is the result of a cooperation between 16 researchers from eleven Mexican academic institutions.
Runoff Prediction in Ungauged Basins
A synthesis of international catchment hydrology research, for researchers and professionals in hydrology, soil science, and environmental and civil engineering.
Flows and Practices
For the past two decades, Integrated Water Resources Management (IWRM) has been the dominant paradigm in water resources. This book explores how ideas of IWRM are being translated and adapted in Mozambique, South Africa, Tanzania, Uganda and Zimbabwe. Grounded in social science theory and research, it highlights the importance of politics, history and culture in shaping water management practices and reform, and demonstrates how Africa has clearly been a laboratory for IWRM. While a new cadre of professionals made IWRM their mission, we show that poor women and men may not have always benefitted. In some cases IWRM has also offered a distraction from more critical issues such as water and land grabs, privatisation, the negative impacts of water permits, and a range of institutional ambiguities that prevent water allocations to small and poor water users. By critically examining the interpretations and challenges of IWRM, the book contributes to improving water policies and practices and making them more locally appropriate in Africa and beyond.
Trade in Water Under International Law
It is clear that more sustainable and efficient use of fresh water resources will become crucial in future global water management to avoid major threats to biological life. Trade in Water Under International Law offers a careful and well-reasoned introduction and analysis of this emerging and largely unchartered subject of international trade law, which has hitherto been of key importance in domestic law and policy, exploring the potential and limits of addressing the use of water resources in the context of World Trade Organization law.
