To achieve sustainable utilization of urban water resources and sustainable social and economic development and to relieve the supply–demand pressure related to water resources in Jiamusi, a simulation model based on system dynamics theory is established to identify the feedback mechanism and the causal relationship among the factors affecting the sustainable utilization of water resources. The conditions regarding the utilization of water resources in Jiamusi in 2010 are taken as the benchmark for the model, and the supply–demand structure of urban water resources and the geographical characteristics of the region are used as the basis for its establishment. The model is divided into five subsystems described by 64 variables to simulate the supply–demand structure of the water resources in the region, as well as both the individual supply and demand structures, and thus to obtain the supply–demand conditions and the trends of variation in water resources in the short, medium and long terms. The results show that seriously unbalanced supply–demand conditions for water resources will prevail in Jiamusi in the future. By 2030, the supply–demand ratio will be only 0.5987; the level of development and utilization of surface water resources and transit water resources will be relatively low, and the groundwater resources will still be suffering excessive exploitation; the industrial water demand will be greatly increased, and agricultural development will be restricted. With a focus on the problems that may arise in the utilization of water resources at present and in the future, a proposal regarding the realization of the sustainable utilization of water resources and sustainable social and economic development in Jiamusi is presented. The outcomes of this research have important theoretical and practical significance for providing guidance regarding the scientific and reasonable utilization of water resources in Jiamusi.

Water Resource Utilization

In addition to the social economy and the rapid development of industry and agriculture, water demand is increasing and poses challenges in the over-exploitation of water resources. This research establishes a model to assess the sustainable exploitation of water resources based on system dynamics theory and STELLA software, which solves the imbalanced allocation of industrial water, agricultural water and domestic water. The model is composed of two parts: the water quantity system (including economy, population, water availability and water demand) and the water quality system (composed of the aquatic environment), which is suitable for Chengde City with a water resource shortage. The proposed model is established by data of Chengde City from 2007 to 2016 and is verified by 2017 data. Furthermore, in order to compare the water quality and water utilization of Chengde City under different development scenarios up to 2025, the sensitivity analysis of each variable (e.g., population) is carried out in this model, and thereby the water resource utilization scenarios are acquired. Specifically, four scenarios are designed and denoted: Scenario 1: keeping the status quo unchanged, Scenario 2: slowing down economic development and devoting more energy to environmental protection, Scenario 3: only focusing more on economic development and Scenario 4: aiming at steady and rapid economic growth and an eco-friendly environment. The results shows that Scenarios 2 and 3 facilitate high-effective water resource utilization compared with the current development, Scenario 1. Scenario 4 fosters the balance of water resources supply–demand in the future and preserves the water quality. This study provides an inspiring method for realizing the sustainable utilization and optimizing allocation of water resources in Chengde City.

Taihang Mountain

In the 21st century, diminishing water resources have become a global concern. The Taihang Mountain area plays an important role in the sustainable development of the Bohai coastal area in Beijing, Tianjin and Hebei because of its special geographical location and features; but due to drought and deficiency of water, the Taihang Mountain area is faced with the dual problems of poverty and ecological vulnerability. It seems particularly important to develop and utilize the water resources in a sustainable manner as water is one of the key factors in promoting local economic development and improving the ecological environment. This paper investigates, from the perspective of water cycle and water transformation, the seepage recharge mechanism in slopes and river valleys, taking into account the hydrological features of the Taihang Mountain area and the hydro-geological features of slopes and river valleys in the area. Based on analysis of the formation process and characteristics of shallow groundwater resources, this paper puts forth the idea of “weak water consolidation” for sustainable development of water resources, and three groundwater development and utilization techniques in respect of seepage through rock-soil interfaces and weathered rock fissures in slopes and seepage in river valleys, offering a powerful support to the economic development and environmental improvement in the Taihang Mountain area.

Water is increasingly taking center stage when it comes to coping with climate change. Especially in urban areas, negative consequences from heavy rainfall events and prolonged dry periods are rising worldwide. In the past, the various tasks of urban water management were performed by different departments that often did not cooperate with each other (water supply, wastewater disposal, green space irrigation, etc.), as the required water supply was not a question of available water volumes. This is already changing with climate change, in some cases even dramatically. More and more, it is necessary to consider how to distribute available water resources in urban areas, especially during dry periods, since wastewater treatment is also becoming more complex and costly. In the future, urban water management will examine water use in terms of its various objectives, and will need to provide alternative water resources for these different purposes (groundwater, river water, storm water, treated wastewater, etc.). The necessary technological interconnection requires intelligent digital systems. Furthermore, the water industry must also play its role in global CO2 reduction and make its procedural treatment processes more efficient; this will also only succeed with adequate digital systems. Although digitization has experienced an enormous surge in development over the last five years and numerous solutions are available to address the challenges described previously, there is still a large gap between the scope of offerings and their implementation. Researchers at Hof University of Applied Sciences have investigated the reasons for this imbalance as part of WaterExe4.0, the first meta-study on digitization in the German-speaking water industry, funded by the German Federal Ministry of Education and Research. Only 11% of roughly 700 identified products, projects and studies relate to real applications. For example, the surveyed experts of the water sector stated that everyday problems are considered too little or hardly at all in new solutions, which greatly overburdens users. Furthermore, they see no adequate possibility for a systematic analysis of new ideas to identify significant obstacles and to find the best way to start and implement a digitization project. The results from four methodologically different sub-surveys (literature and market research, survey, expert interviews and workshops) provide a reliable overview of the current situation in the German-speaking water industry and its expectations for the future. The results are also transferable to other countries.

The purpose of this article is to study the processes of water quality management, which are considered as the main factor of the strategic social and economic development of the region and also to form tools supporting this process. The article analyzes the state and development trends of the water sector of the Rostov region from the standpoint of solving the problems of its strategic social and economic development. The authors demonstrate the possibility of intellectualization of regional strategizing processes through the use of water quality monitoring of the knowledge of experts with the use of fuzzy logic. The review of existing approaches to the assessment of water resources quality is given. It is shown that these approaches do not take into account the different requirements of water users to the content of chemicals and compounds in the water but assess the state of water resources in terms of conformity of concentration indices of polluting substances to maximally allowable concentrations. The authors suggest assessing the quality of water resources in compliance with the criteria of the contamination of water resources set for every category of water users. The approach proposed by the authors implies the assessment of water quality in two modes – differentiated and complex. Meanwhile, the suggested tools are universal and can be used in the systems of regional strategizing of the use of various water basins. A conceptual representation of the structure of the management system of water resources quality in the region within the system of regional strategizing is formed and the main problems of its development are identified.
