The Wuding River

Understanding and quantifying changes in hydrological systems due to human interference are critical for the implementation of adaptive management of global water resources in the changing environment. To explore the implications of hydrological variations for water resources management, the Wuding River Basin (WRB) in the Loess Plateau, China, was selected as a case study. Based on the Budyko-type equation with a time-varying parameter n, a human-induced water–energy balance (HWEB) model was proposed to investigate the hydrological variability in the WRB. The investigation showed that runoff continuously reduced by 0.424 mm/a during 1975–2010, with weakly reducing precipitation and increasing groundwater exploitation causing a decrease in groundwater storage at a rate of 1.07 mm/a, and actual evapotranspiration accounting for more than 90% of precipitation having an insignificantly decreasing trend with a rate of 0.53 mm/a under climate change (decrease) and human impact (increase). Attribution analysis indicated that human-induced underlying surface condition change played a dominant role in runoff reduction by driving an increase in actual evapotranspiration, and that mainly impacted the overall decrease in runoff compounded by climate change during the entire period. It is suggested that reducing the watershed evapotranspiration and controlling groundwater exploitation should receive greater attention in future basin management.

Abstract Since 2011, China has implemented its most stringent water management system to effectively protect water resources and guarantee socioeconomic development. More basin-scale water division schemes have been developed to act as references for basin-scale water resources management. Water dispatching during dry periods is an effective way to guarantee the water supply for the river basin, and is also an important component of basin-scale water resources management. Given this, the present study proposes a framework for the water dispatching of river basins during dry periods under the most stringent water management system in China. This framework mainly consists of the analysis and forecasting of rainfall and inflow, the dispatching requirements for the main water users, major reservoirs, and sections, as well as safeguard measures. The Jian River Basin in South China is presented as a case study. The total discharge of the Gaozhou Reservoir in 2017 was 25 million m3 more than the target discharge specified in the water dispatching scheme, and the total water storage utilization ratio during the dispatch period was 4.7% higher than the target utilization ratio. These factors demonstrate the effectiveness and applicability of the proposed framework. HIGHLIGHT The proposed framework for the water dispatching of river basins during dry periods provides reliable technical support for water use security under the most stringent water management system in China, and is demonstrated to be both effective and applicable.

The article presents the method of water resources management in the Asa river basin and indicators of water intake, water supply and assessment of water quality. Water is an economically important resource that determines the sustainability of a country’s development. New trends show that water issues are becoming more complex with other sectors, including agriculture, energy, industry, transport, and communications, as well as with social sectors: education, environment, and healthcare, rural or regional development. The rational use of water resources, as well as the protection of water resources and access to drinking water are an important priority for the world community. The Republic of Kazakhstan is no exception, since the deficit of water resources is growing every year. Today’s global challenges, especially climate change and population growth, are making the situation even more worrisome. Climate change is caused by dynamic processes on Earth, external influences such as fluctuations in the intensity of sunlight, and recent human activities. Consequently, in the conditions of Kazakhstan, where water resources are limited, and irrigation develops in various natural and climatic zones, further intensification of irrigated agriculture can be carried out through the development of environmentally friendly integrated technologies, ecological and reclamation management of water and land resources, ensuring a decrease in the amount of unproductive losses of irrigation water, as well as protection of water and land resources from pollution by collector-waste waters, leaching of organic substances and nutrients, the rate of salt accumulation in the root layer and the rate of alkalization and alkalinization processes. This approach is predetermined by the fact that the existing methods of water resources management inevitably lead to large losses of irrigation water for infiltration, discharge and evaporation, the value of which reaches 60–70% of the water intake.
