Analysis of drought characteristics for improved understanding of a water resource system

Abstract. Droughts are a reoccurring feature of the UK climate; recent drought events (2004–2006 and 2010–2012) have highlighted the UK’s continued vulnerability to this hazard. There is a need for further understanding of extreme events, particularly from a water resource perspective. A number of drought indices are available, which can help to improve our understanding of drought characteristics such as frequency, severity and duration. However, at present little of this is applied to water resource management in the water supply sector. Improved understanding of drought characteristics using indices can inform water resource management plans and enhance future drought resilience. This study applies the standardised precipitation index (SPI) to a series of rainfall records (1962–2012) across the water supply region of a single utility provider. Key droughts within this period are analysed to develop an understanding of the meteorological characteristics that lead to, exist during and terminate drought events. The results of this analysis highlight how drought severity and duration can vary across a small-scale water supply region, indicating that the spatial coherence of drought events cannot be assumed.

The goal of this paper is to identify the major outlines of innovative, integrated and decentralized water management practices, training, research, and development needs in various aspects of soft path water resource management in developing countries of Asia. The decentralized water strategies including science, regulations, training, government policies, and funding for some of the developing countries in Asian region are reviewed. There are two primary ways or paths of meeting water-related needs; one the “hard” path, and the other “soft” path that complements mainly decentralized and open decision-making, application of efficient technology, and environmental protection. One of the soft path decentralized solution being implemented in many developing countries of Asia is small scale rainwater harvesting and management and both government and non-government sectors are promoting the practice on a regional community and family basis. Overall, the paper aims to contribute to the ongoing development of environmentally sound and economically viable approaches to water management in the developing world.

Ecological Water Demand

Habitat loss is a key factor affecting Siberian crane stopovers. The accurate calculation of water supply and effective water resource management schemes plays an important role in stopover habitat restoration for the Siberian crane. In this paper, the ecological water demand was calculated and corrected by developing a three-dimensional model. The results indicated that the calculated minimum and optimum ecological water demand values for the Siberian crane were 2.47 × 108 m3~3.66 × 108 m3 and 4.96 × 108 m3~10.36 × 108 m3, respectively, in the study area. After correction with the three-dimensional model, the minimum and optimum ecological water demand values were 3.75 × 108 m3 and 5.21 × 108 m3, respectively. A water resource management scheme was established to restore Siberian crane habitat. Continuous, area-specific and simulated flood water supply options based on water diversions were used to supply water. The autumn is the best season for area-specific and simulating flood water supply. These results can serve as a reference for protecting other waterbirds and restoring wetlands in semi-arid areas.

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.

Mining cities have undergone the process of extensive exploitation, which always results in a series of water issues. Integrated water resource management is necessary in improving water supply, allocation and quality without damaging economic development. This article constructs a linear optimization model including a ‘Top-Down’ socio-economic mode, and ‘Bottom-Up’ water quality control and water supply–demand modes with integrated water resource management focused on water allocation and water reclamation. Based on computer simulation, the model can propose a water resource management under the constraints of water supply–demand and water quality control, and the model can precisely predict the influences of water resource management on economic development, water utilization and water quality. Taking Ordos, a Chinese national resource city, as a case study, this model addresses a detailed water resource management, including a water allocation plan among industries and water reclamation plan with technologies, selection, arrangement and subsidies. The implementation of water resource management can fulfill multiple objectives on water quantity, water quality and sustainable economic development. This study indicates that water resource management with a comprehensive dynamic model can be a maneuverable approach to realize the sustainable development of economic growth and water resource utilization, as well as formulate the regional development plan.

The Impact

This study uses extended (1880s–2012) rainfall series to examine the implications of historical droughts on water supply yield calculations used in water resource management and drought planning across the English Midlands and Central Wales. UK guidance to water companies is to use climate data from the 1920s to present where possible in modelling to inform water resource management and drought plans; but this period excludes several significant droughts of the late 19th century. This study uses the standardised precipitation index and hydrological modelling (HYSIM and AQUATOR) to investigate the implications of pre-1920s droughts on water resource management. Although drought characterisation identifies two significant droughts in the pre-1920 period, the impact of these events on reservoir storage is less severe than droughts identified in the post-1920 period, indicating that the use of long climate series in water resource modelling is a valuable tool in assessing the robustness of current water resource modelling used in the water resource sector.

Este artículo aborda el campo del manejo de los recursos hídricos y propone un esquema de análisis para estudiar las relaciones entre las instituciones y las prácticas de los actores afectados por las acciones de tales instituciones. Avanza después, en forma preliminar y descriptiva, sobre la exploración de algunas de las categorías presentadas en el esquema propuesto en un caso concreto (Mendoza, Argentina). Reconocemos una doble dinámica de funcionamiento del régimen hídrico: una entre la autoridad hídrica y los grandes y poderosos actores vitícolas y otra entre un conjunto de entidades satélites no hídricas y pequeños productores. Esto lleva a que desde la política hídrica se reproduzca un modelo de producción que claramente beneficia a un sector a costa de otro. HYDROLOGIC ORDER: PRACTICES AND INSTITUTIONS IN MENDOZA, ARGENTINA This article addresses the territory of water resource management and proposes an analytical framework to study the inter-institutional relationships and practices of the stakeholders affected by the actions taken by those institutions. It explores in a preliminary and descriptive form some of the categories presented in the framework proposed for the specific case of Mendoza, Argentina. It identifies a double working dynamic in the hydrologic regime: one between the hydrologic authorities and large-scale and powerful stakeholders of the wine industry and another dynamic between a series of non-hydrologic satellite entities and small-scale producers. This leads to a hydrologic policy that reproduces a production model that clearly benefits one sector at the expense of another.
