Research on the water resources regulation ability model of dams in the Huai He River Basin considering ecological and management factors

Abstract

Abstract.Research that assesses the scheduling ability of dams garners a great deal of attention due to the global water resource crisis. These studies can provide useful and practical suggestions for scheduling the water resources of dams to solve problems, such as addressing ecological water needs and so on. Recent studies have primarily evaluated the schedule ability of dams according to their quantifiable attributes, such as water quantity, flow velocity, etc. However, the ecological and management status can directly determine the possibility and efficiency of a dam's water resource scheduling. This paper presents an evaluation model to assess the scheduling capacity of dams that takes into consideration ecological and management factors. In the experiment stage, this paper takes the Sha Ying river of the Huai He River Basin as an example to evaluate the scheduling ability of its dams. The results indicate that the proposed evaluation model can provide more precise and practical suggestions. IntroductionRecent studies evaluating the scheduling abilities of dams have increased amidst wide concerns about the global water resource crisis [8]. However, past research has primarily focused on water schedule on flood control, drainage, water supply, pollution prevention, control, and so on [7]. With the development of social economy and the increased efficiency of water resources, water ecology has been attracting a great deal of attention [11]. Past studies assessing the water schedule ability of dams were more concerned about water quantity and water quality but ignored the importance of the management status of dams [2]. To the best of our knowledge, related researchers avoided taking both management and ecological factors into consideration during their modeling for assessing water schedule ability [5]. However, the ecological and management factors can have a serious effect on the water schedule ability of dams [3]. Thus, some researchers adopted these qualified factors to obtain an imprecise assessment of dam scheduling ability [4]. Nonetheless, these indexes can be quantified and considered in order to make precise evaluations of dam scheduling abilities with scientific approaches [6]. This paper investigates fifty experienced experts who have been working on managing related dams for many years and obtains their rates on the management status of the dams. As for the ecological factors, this paper utilizes water quantity and the density of NH3-N and COD elements, which are critical influences on the ecological status of water around dams, to represent the water ecology variable.
