Groundwater in the coastal zone: two-day course

During IAHR 2015 Deltares will organize a two-day course on groundwater in the coastal zone. The course will provide participants with (1) principles and procedures of variable density groundwater flow and coupled solute transport, (2) salinisation of groundwater systems and fresh-saline groundwater flow phenomena in the coastal zone, (3) monitoring techniques for fresh-brackish-saline water systems and (4) modelling experiences through hands-on training in computer workshops.

 
Estimating real-time predictive hydrological uncertainty

Flood early warning systems provide a potentially highly effective flood risk reduction measure. The effectiveness of early warning, however, is affected by forecasting uncertainty: the impossibility of knowing, in advance, the exact future state of hydrological systems. Early warning systems benefit from estimation of predictive uncertainties, i.e. by providing probabilistic forecasts. On 1 April 2015 Jan Verkade defended his PhD thesis «Estimating real-time predictive hydrological uncertainty». The dissertation describes research in estimating the value of probabilistic forecasts as well as in skill improvement of estimates of predictive uncertainty.

 
Water & Heritage: Material, conceptual and spiritual connections

Initiated by ICOMOS Netherlands, a new book on the heritage of water management has been published, just before the World Water Forum: Water and Heritage. It contains 26 articles from ICOMOS members worldwide and prominent international scholars. The book contains a foreword by Ms Irina Bokova, director-general of UNESCO. Edited by Willem Willems and Henk van Schaik, the book will be presented on 13 April 2015 during the World Water Forum in Korea. Free to read on the website of publisher Sidestone.

 
Key Concepts in Water Resource Management – book of the month March 2015

The vocabulary and discourse of water resource management have expanded vastly in recent years to include an array of new concepts and terminology, such as water security, water productivity, virtual water and water governance. While the new conceptual lenses may generate insights that improve responses to the world's water challenges, their practical use is often encumbered by ambiguity and confusion.

 
International Expert Workshop on the Water-Energy-Food Nexus

The «International Expert Workshop on the Water-Energy-Food Nexus: Challenges and Opportunities in Mekong Region» was held 22–23 January 2015 at the Asian Institute of Technology, Thailand. The presentations are now avaialble.

 
International Journal of Climate Change Strategies and Management

The International Journal of Climate Change Strategies and Management publishes papers on scholarly research, projects and other initiatives dealing with policy-making on climate change, and methodological approaches to cope with the problems deriving from climate change. Due consideration is given to environmental, economic, social and political aspects and especially the links and leverages that can be attained by this holistic approach. Authors are invited to submit papers.

 
Managing Water Resources under Climate Uncertainty

Managing Water Resources under Climate Uncertainty: Examples from Asia, Europe, Latin America, and Australia – a new book by Sangam Shrestha, A.K. Anal, P.A. Salam and Michael van der Valk (eds) – has just been published by Springer. The book describes the impacts of climate change on the water cycle in Asia and Europe, and compares options for adaptation while looking at different regions that each have their own particularities. The book contains examples from the Mediterranean, Central Highlands of Vietnam, the Citarum River Basin (Indonesia), Nam Ou River Basin (Lao), Koshi River Basin, Chaliyar River Basin (Kerala, India), Mekong tributaries (including Can Tho, Sesan and Sre Pork Basin), Cambodia, Bhutan, South-Eastern Indian coast, Leh (Northwestern Himalaya, India), Nepal (Disaster Risk Reduction), Adelaide (Australia), Mexico, Chindwin River (Myanmar), Brahmaputra River. With a foreword by Michel Jarraud (Secretary-General of WMO and Chair of UN-Water) and Blanca Jiménez (Director, Division of Water Sciences, UNESCO).

 
Sustainability of global water use: past reconstruction and future projections

Overuse of surface water and an increasing reliance on nonrenewable groundwater resources have been reported over various regions of the world, casting significant doubt on the sustainable water supply and food production met by irrigation. To assess the limitations of global water resources, numerous indicators have been developed, but they rarely consider nonrenewable water use. In addition, surface water over-abstraction is rarely assessed in the context of human and environmental water needs. Yoshihide Wada and Marc Bierkens performed a transient assessment of global water use over the historical period 1960–2010 as well as the future projections of 2011–2099, using a newly developed indicator: the blue water sustainability index (BlWSI).
