Four Levels

With nearly 30 years' experience of managing stored surface water for water supply, the Municipal Water and Sewage Company of Seville (EMASESA), has introduced a Water Supply Natural Resources Vigilance Program. It consists of four levels that are mutually complementary: early warning system; vigilance of raw water resources; research; and integration of limnological knowledge. Selecting the reservoir that should be used, intake depth, transfer strategies, etc, are some examples of active management that this Vigilance Program allows us to achieve. Guaranteeing high quality raw water resources, at all times, which therefore favours their treatment, is one of the priority objectives for EMASESA. This is because it not only has repercussions from an economic point of view but it also contributes to the efficient and sustainable use of water resources.

Water Resources Utilization

With the development of industrial and agricultural production and the social economy, the demand for water resources has gradually increased. In this paper, based on the principles of system dynamics, a sustainable water resources utilization model with coupled water quality and quantity is established using STELLA software to assess the sustainable use of water resources. The model includes two modules: a water supply module and a water quality module. The water supply module includes four sub-systems: economy, population, water supply, and water demand. The water quality module consists of an environmental sub-system. The model is suitable for Tianjin, where water resources are scarce. Calibration is performed using data from 2013–2016, and verification is performed using data from 2017. The simulation results are good. In order to compare the sustainable use of water resources in different development scenarios in Tianjin for 2025, a sensitivity analysis is performed for each variable, and four decision variables are selected to establish four water resources use scenarios (Scenarios 1–4). The results show that, compared with scenario 1, water shortages in scenarios 2 and 3 are delayed. Scenario 4, with stable economic growth and environmental consideration, can effectively resolve the contradiction between water supply and demand in the future, and is more conducive to the improvement of water quality. Finally, based on the above research, measures to solve water resources problems are proposed, in order to provide a reference for the sustainable use of water resources and optimization of water resources allocation in Tianjin.

Challenging Environment

Abstract Sudan is a vulnerable and challenging environment as a result of its climate, hydrology, and hydrogeology. Other entrenched human factors, such as authoritarian rule, limited historical investment in rural water services and the gradual decline of national institutions make it particularly difficult. This has manifested itself today into low levels of water supply coverage particularly amongst rural communities. Trust between rural communities in Kassala and government institutions has also declined for those left behind in rural hinterlands. Providing sustainable and resilient water services in rural Sudan is difficult work, not least because of high rainfall variability, inadequate infrastructure and the lack of continuous external support to communities when problems arise. This paper describes efforts to strengthen links between water resources management and WASH, and the challenges faced when national institutions responsible for water resources and water supply are weak. It documents recent efforts to ensure water supply services can provide water year round and increase collaboration between rural communities and mandated government authorities. It is intended to be read by government personnel, non-governmental organisations and other staff that are directly involved in implementing integrated water resource management programmes in complex environments.

Abstract Fast-growing water demand, population growth, global climate change, and water quality deterioration all drive scientists to apply novel approaches to water resource management. Nanotechnology is one of the state-of-the-art tools in scientists’ hands which they can use to meet human water needs via reuse of water and utilizing unconventional water resources. Additionally, monitoring water supply systems using new nanomaterials provides more efficient water distribution networks. In this chapter, we consider the generic concepts of nanotechnology and its effects on water resources management strategies. A wide range of nanomaterials and nanotechnologies, including nano-adsorbents, nano-photocatalysts, and nano-membranes, are introduced to explain the role of nanotechnology in providing new water resources to meet growing demand. Also, nanomaterial application as a water alternative in industry, reducing water demand in the industrial sector, is presented. Another revolution made by nanomaterials, also discussed in this chapter, is their use in water supply systems for monitoring probable leakage and leakage reduction. Finally, we present case studies that clarify the influence of nanotechnology on water resources and their management strategies. These case studies prove the importance and inevitable application of nanotechnology to satisfy the rising water demand in the modern world, and show the necessity of nanotechnology awareness for today's water experts.

Scale Data

Recent patterns of water use and supply in California are presented based on a new data set compiled from the California Department of Water Resources water balance data for 2002 through 2016. The water use and supply include surface water and groundwater, although groundwater reporting has been incomplete. These data are used to support the Water Plan released every 3 to 5 years and are the most comprehensive and finest spatial- and temporal-scale data set for California water resources. First, using the Bay–Delta watershed as a case example, we show that recent fluctuations in water use are highly correlated with variations in precipitation. Developed water supplies and use show these fluctuations, but they are modified by reservoir inflows and releases, groundwater supplies, and Delta outflows. Second, although the annually precipitated water supply in the Bay–Delta varies by about 30%, the developed water supply damps this considerably. The water management system maintained nearly constant agricultural water use even in periods of intense drought, with year-to-year variation of about 7%. Variability in urban water use is higher (∼20%), largely from conservation during periods of drought. Finally, this information can help improve water resource management because it connects regional-scale data to meaningful policy decision-making at county and sub-county levels. At a time when water policy and management are being re-evaluated across the American West in the light of changing climate, decision-making informed by science and data is urgently needed. The statewide water balance data provide the means to establish a consistent, quantitative framework for water resource analysis throughout the state.

Abstract. Most of the forested headwater catchments are an important source of water supply in many parts of the world. A prime example is southeast Australia where forests supply major river systems and towns and cities with water. It is critical for an informed and adaptive water resource management to understand changes in streamflow caused by vegetation changes in these headwater forest catchments. Natural disturbances such as bushfires and anthropogenic activities like forestation, deforestation, or logging alter vegetation, evapotranspiration and soil water status, and may affect water supplies. Although catchment water yield is mainly controlled by climatic conditions, but it is also strongly influenced by land cover changes because of natural disturbances and anthropogenic activities. It is necessary to accurately estimate streamflow in water supply catchments subjected to dramatic land surface changes. This paper summarises the methods commonly used to investigate the impacts of land cover change on water resources, and provides some examples of impacts of afforestation/deforestation and bushfire on water resources in two southeast Australian catchments.

Water is an integral part of ecosystems. Water is essential to earth's living creatures and central to maintaining the earth's ecosystems. In most of the world, both water quantity and quality problems are becoming more acute, since the available water resources are being over-utilized and stressed beyond the sustainability point. The contemporary global water crises including inefficient use and lack of equitable distribution are mainly due to the crises of governance. Water governance emerged as a comprehensive framework by replacing all the existing paradigms including integrated water resource management. Though water governance focuses many aspects in ensuring sustainable use of water resources and its equitable distribution, reallocation of water resources may be the most appropriate policy option to achieve these objectives. Reallocation will systematically address the uneven distribution of water resources across the sectors and prevent excessive allocation of water to a particular sector. Based on secondary sources, this chapter analyzes the challenges involved in water governance in terms of water reallocation in the Arab countries where the allocation of water for agriculture is very high. Addressing water scarcity in the Arab region lies mainly in effectively managing the growing demand. Major water governance challenges with respect reallocation of water resources are tariff, metering, and billing, which led to the excessive use in an unprecedented manner.

The Kota Makassar water utility serving (<em>Perusahaan Daerah Air Minum</em> - PDAM) faces a significant problem in managing water resources for their drinking water supply. The problems comprise raw water supply, the vulnerability of water quality, infrastructures, costs, and climate change uncertainty. The availability of clean water is one of the problems in the field of national defense. Because water is the main source of life in all sectors, be it agriculture or livestock. This study is aimed at assisting officials in making an adaptive and resilient decision. It involves inter-and cross-disciplinary studies within Robust Decision-Making (RDM) in water resources management planning for drinking water supply and disaster mitigation in Makassar. This research applies a qualitative approach in data analysis; reviewing strategies used by the utility management to anticipate all uncertainty, long-term strategies feasibility from simulation models, analyzing potential vulnerability scenarios, and the trade-off for an adaptive and robust decision in water resources management planning for drinking water supply in Makassar through RDM. The novelty lies in the raw water management policy that is more adaptive toward potential vulnerability and presents a variety of raw water supply alternatives in the long term. Reviews against the document of drinking water Master Plan found that the absence of harmony along with a high level of anticipation towards the threat of climate change along with their impact, as well as the threat of the raw water supply limitations due to the exogenous problems beyond the reach of human beings capacity, will result in global and long-term impact.
