Water reclamation and reuse have become essential components of water resources management in Vitoria-Gasteiz, by helping to overcome historical water deficits experienced by the city with respect to water allocations set in 1973 with the Metropolitan Area of Bilbao, for the conjunctive use of the Urrunaga-Ullibarri reservoirs system. By generating a reliable flow of 35,000° m3/day of high quality reclaimed water, the options available for integrated water resources management have widely expanded as to allow in-stream river flow substitution, agricultural irrigation, seasonal storage of reclaimed water, and more favorable flood control policies for the Urrunaga-Ullibarri reservoirs system. Those management options have been made possible thanks to the implementation of an extensive and elaborated water distribution and storage system (reuse component) that allows distribution of reclaimed water to 10,000 ha of farmland, seasonal storage in a 7 hm3 reservoir, partial substitution of in-stream river water, and the potential consideration of water augmentation in reservoirs. The continuous support and promotion by agricultural users, the excellent operation and maintenance records of the project, and its favorable economic features have been instrumental in assuring a wide acceptance of this innovative water management option, under the Vitoria-Gasteiz social, economic, geographical and water resources conditions.

Essential Components

Water reclamation and reuse have become essential components of water resources management in the Metropolitan Area of Barcelona, by helping to develop additional water resources in the lower Llobregat River, one of its main sources of water supply. By generating a reliable flow of 300,000 m3/day of high quality reclaimed water, the options available for integrated water resources management have widely expanded to allow in-stream river water substitution, restoration of natural wetland areas, agricultural irrigation, and supply to a seawater intrusion barrier. Those management options have been possible thanks to the implementation of an extensive water distribution system that allows distribution of reclaimed water to a point 15 km upstream of the reclamation facility, and to a seawater intrusion barrier within a few kilometres of the plant. The cost of producing reclaimed water using a physico-chemical process (0.05 €/m3) and the investment required for such a facility (0.21 €/m3 annual capacity) are very close to those of similar large scale projects in Spain. However, higher degrees of treatment, such as demineralization for agricultural irrigation and for injection into a seawater intrusion barrier, result in considerable increases of both water reclamation cost and investment costs.

This effort discusses and evaluates alternative water management options to alleviate water stress and meet water needs in insular entities of the Aegean Archipelago, within the framework set by the principles of Integrated Water Resources Management (IWRM) and of the Water Framework Directive 2000/60/EC. Options are presented and assessed to determine integrated applicable strategies reflecting technical, economic, social and environmental constraints. The assessment is based on the application of the WaterStrategyMan Decision Support System (WSM DSS), developed under the Fifth Framework Programme, and is performed for six islands of the region. Results emphasize the need to understand the interconnections between social, technical, economic, and environmental problems in order to reach integrated solutions. In the dynamic context of current societies, pragmatic policy initiatives are needed to improve the means of preventing and addressing such issues, as well as new institutional structures to handle appropriately competing and conflicting water demands and development objectives.

For resolving adverse impact in water sector (such as severe flooding, sedimentation of river channels, erosion of the riverbanks, scarcity of water during the dry season, saline intrusion and environmental degradation in particular in the Southwest, cyclones and tidal surges in coastal areas, heavy arsenic contamination of groundwater etc.) in Bangladesh, lot of studies and programs have been under taken by the Government of Bangladesh during the last fifty years. Current global climate change and upstream withdrawal of water have made the water related problems more critical. Under these circumstances, water resources management needs more comprehensive and integrated approaches. Early day’s water management in Bangladesh were mainly involved to Flood Control Drainage and Irrigation (FCDI) project which caused detrimental effects of other sectors. The issue of Integrated Water Resources Management (IWRM) has been increasingly highlighted after the 1990's. The Flood Action Plan (FAP, 1989-95), Bangladesh Water and Flood Management Strategy (BWFMS, 1995), The Ganges Water Treaty (1996), National Policy for Safe Water Supply and Sanitation (1998), National Water Policy (NWPo, 1999), Guidelines for Participatory Water Management (GPWM, 2000), National Water Management Plan (NWMP, 2004), National Water Resources Database (NWRD, 2001), Regional Technical Assistance (RETA, 2009), Bangladesh Water Act (DBWA, 2013)are the major examples of IWRM practice in Bangladesh.For the evaluation of Integrated Water Resources Management (IWRM) activities in Bangladesh, the three IWRM tools i.e. ‘Enabling Environment’, ‘Institutional Framework’ and ‘Management Instrument’ have been used as a methodology. Lots of Online Questionnaire has been done to the National Water Expertise for getting more information and strengthening the scope of work. Although lot of constraints are existing to develop IWRM plan in Bangladesh, yet the existing policy, plan, guideline, law, institution and information system provide a sound basis for the IWRM implementation in Bangladesh considering the principals of IWRM i.e. efficiency, equity, environmental sustainability. The study has shown that, the progress towards Integrated Water Resources Management (IWRM) in Bangladesh has been good. Much remains to be done. Nevertheless, advancing IWRM is a process of incremental steps and the Bangladesh water-related sector is clearly moving in the right direction towards the IWRM plan. Finally the study has drawn recommendations for effective implementation of IWRM activities in Bangladesh.

Resources Management

Integrated water resources management at the catchment scale, considering the full water cycle as manageable, is a primary approach to improve water use efficiency and promote sustainable water management solutions. To this purpose, advanced modelling tools are required to quantify the physical and economic effects of alternative land management options. This work presents an application of a spatially distributed physically based hydrological model to the Bonis experimental watershed located in the mountain area of Sila Greca (southern Italy). Different infiltration models were tested to better reproduce discharge observations at basin outlet. The model will be used for evaluating different land use/management scenarios, combined with climate change forcing, to quantify the effect of alternative management options on the land-water cycle. This work is part of the INNOMED project (Innovative Options for Integrated Water Resources Management in the Mediterranean) funded by ERA-NET COFUND WATERWORKS 2015 call.

Abstract. The management process of Integrated Water Resources Management (IWRM) consists of aspects of policies/strategies, measures (engineering measures and non-engineering measures) and organizational management structures, etc., among which engineering measures such as reservoirs, dikes, canals, etc., play the backbone that enables IWRM through redistribution and reallocation of water in time and space. Engineering measures are usually adopted for different objectives of water utilization and water disaster prevention, such as flood control and drought relief. The paper discusses the planning and implementation of engineering measures in IWRM of the Changjiang River, China. Planning and implementation practices of engineering measures for flood control and water utilization, etc., are presented. Operation practices of the Three Gorges Reservoir, particularly the development and application of regulation rules for flood management, power generation, water supply, ecosystem needs and sediment issues (e.g. erosion and siltation), are also presented. The experience obtained in the implementation of engineering measures in Changjiang River show that engineering measures are vital for IWRM. However, efforts should be made to deal with changes of the river system affected by the operation of engineering measures, in addition to escalatory development of new demands associated with socio-economic development.
