<p>Streamflow measurement and prediction are important for proper water resources management. In this case, the water resources problem is drought in the Coastal Mountains of British Columbia, Canada, where a village is drawing drinking water from a mountain stream. Because of challenges with other flow measurement methods in streep turbulent streams, salt dilution gauging is the best way to measure streamflow, but it is labour intensive.</p><p>To advance progress towards the singularity, an intelligent automated salt dilution gauging system was deployed, and provides good results, but some disturbances occur due to the presence of a tributary and a drinking water intake. We show how this noise can be turned into signals and discuss a range of other signals that together provide input for the discharge record.</p>

The approach applied in methodology development and application in stakeholder management that contributes to sustainable cross-border drinking water supply and integrated water resources management within the Adriatic region is presented. It was developed through the strategic project Networking for Drinking Water Supply in the Adriatic Region (DRINKADRIA), where eight countries across the Adriatic region contributed in implementation to assess and evaluate the framework for sustainable cross-border drinking water resources management given the constraints and challenges within the project area. The interlinkage among stakeholders’ inputs and pertinent Sustainable Development Goal 6 (SDG6) indicators puts into perspective the added value of stakeholders’ contribution in addressing relevant issues and options for sustainable cross-border drinking water resources management and SDG6 targets reinforcement.

Abstract. The EC-project BRAHMATWINN was carrying out a harmonised integrated water resources management (IWRM) approach as addressed by the European Water Initiative (EWI) in headwater river systems of alpine mountain massifs of the twinning Upper Danube River Basin (UDRB) and the Upper Brahmaputra River Basins (UBRB) in Europe and Southeast Asia respectively. Social and natural scientists in cooperation with water law experts and local stakeholders produced the project outcomes presented in Chapter 2 till Chapter 10 of this publication. BRAHMATWINN applied a holistic approach towards IWRM comprising climate modelling, socio-economic and governance analysis and concepts together with methods and integrated tools of applied Geoinformatics. A detailed description of the deliverables produced by the BRAHMATWINN project is published on the project homepage http://www.brahmatwinn.uni-jena.de.

The present study explores the process of Greece’s current decarbonisation transition and its energy policy regarding the country’s two coal-mining areas. Using the Region of Western Macedonia as a case study, we aimed at providing a holistic approach—as until now only few attempts have been made to systematise the ‘Just Transition Plans’ in European Union (EU)—for raising awareness on issues related to water resource management in post-lignite areas and analysing the use of hydropower in Greece. Our research draws on a flexible method approach, serving as a tool to identify gaps in current knowledge and practices, based on two stages—first the analysis of existing literature, reviews, and sources from government’s core strategies, as well as policy and decision-making papers, and then formulating research questions by synthesising relevant data. In Greece, both ‘Just Transition Development Plan of Lignite Areas’ and hydropower production practices overlook water resources management. By summarising our findings and identifying gaps that remain in current approaches, this work indicates future directions by suggesting processes necessary for addressing the complex issue of adoption of sustainable water resources management measures in post-lignite eras in accordance with EU’s water policy.

In this study the sustainability of integrated water resources management in Amsterdam has been reviewed using the City Blueprint approach. The City Blueprint® is a set of 24 dedicated indicators divided over eight categories, i.e., water security, water quality, drinking water, sanitation, infrastructure, climate robustness, biodiversity and attractiveness, and governance including public participation. In 2006 the various urban water-related services in Amsterdam were brought under one roof, culminating in the country's first water cycle company called Waternet. Waternet is responsible for surface water (rivers, canals, ditches and lakes), groundwater, stormwater, drinking water supply and waste water treatment. The city's unique water cycle approach has proved highly beneficial. Currently Amsterdam is the best performing city of the 30 cities assessed so far. This can be explained by: (1) a long-term vision and a multi-level water governance approach, (2) integration of water, energy and material flows (e.g., struvite production), (3) the entanglement between urban quality and water management, and (4) the transparent communication to and feed-back from customers, i.e., farmers and citizens. Surface water quality and biodiversity remain future challenges.

The integrated water resources management (IWRM) paradigm has emerged as the main guiding framework for water resources development and management. Since the IWRM approach started to gain prominence with the 1992 Rio de Janeiro Summit and the Dublin Conference, developing and developed countries worldwide have adopted and transposed the tools and principles embodied in this holistic approach into their national policies as well as their regulatory and institutional frameworks. The scientific community has performed extensive studies within the IWRM field. In fact, there is a growing literature analysing multi-dimensional functions to pursue an IWRM approach in water resources management. The main objective of this study is to perform a literature review of the scientific knowledge in the IWRM field published between the years 2000 and 2011. A total of 353 papers published in scientific journals were carefully reviewed and extracted from the ISI Web of Science database. The main results show that: (a) the dominant research topics in IWRM analysis focus on its institutional framework, on equitable water allocation (sustainable management of water resources), and on IWRM implementation and stakeholder participation; and (b) the leading countries in scientific research into IWRM are Germany, the USA and South Africa.

The potential of karst aquifers as a drinking water resource is substantial because of their large storage capacity gained in the course of carbonate dissolution. Carbonate dissolution and consequent development of preferential paths are also the reasons for the complex behavior of these aquifers as regards surface and underground flow. Hydrological modeling is therefore of paramount importance for an adequate assessment of flow components in catchments shaped on karsts. The cross tabulation of such components with geology, soils, and land use data in Geographic Information Systems helps decision makers to set up sustainable groundwater abstractions and allocate areas for storage of quality surface water, in the context of conjunctive water resources management. In the present study, a hydrologic modeling using the JAMS J2000 software was conducted in a karst area of Jequitiba River basin located near the Sete Lagoas town in the state of Minas Gerais, Brazil. The results revealed a very high surface water component explained by urbanization of Sete Lagoas, which hampers the recharge of 7.9 hm3 yr−1 of storm water. They also exposed a very large negative difference (−8.3 hm3 yr−1) between groundwater availability (6.3 hm3 yr−1) and current groundwater abstraction from the karst aquifer (14.6 hm3 yr−1), which is in keeping with previously reported water table declines around drilled wells that can reach 48 m in old wells used for public water supply. Artificial recharge of excess surface flow is not recommended within the urban areas, given the high risk of groundwater contamination with metals and hydrocarbons potentially transported in storm water, as well as development of suffosional sinkholes as a consequence of concentrated storm flow. The surface component could however be stored in small dams in forested areas from the catchment headwaters and diverted to the urban area to complement the drinking water supply. The percolation in soil was estimated to be high in areas used for agriculture and pastures. The implementation of correct fertilizing, management, and irrigation practices are considered crucial to attenuate potential contamination of groundwater and suffosional sinkhole development in these areas.
