Water Demands

Large-scale reservoirs have played a significant role in meeting various water demands and socio-economic development, while they also lead to undeniable impacts on the environment and ecology. The Longyangxia reservoir located on the Yellow River is the first large-scale reservoir on the upper Yellow River with a control area of 18% of the entire Yellow River Basin. Since it was put into operation in 1987, it has made great contributions to the national economy for over 30 years. In this study, the socio-economic benefits of the Longyangxia reservoir in power generation, water supply, flood control, and ice prevention are investigated. More importantly, its impacts on the ecology and environment are also presented and analyzed, such as the impacts on river morphology, flow regimes, peak flow, fish, phytoplankton, and zooplankton. It can be concluded that the construction of the Longyangxia reservoir contributes greatly to socio-economic benefits, the water area nearby has formed a new ecological environment, and the trophic level of the aquatic environment has probably increased.

Henan Yellow River floodplain is the area for flood flowing, flood detention and sand sediment; it is also necessary for the production and living. With the rapid economic development along the Yellow River, floodplain development is increasing, occupying some land and water area. Due to the lack of unified planning, they have brought certain difficulties to flood control management and scientific decision-making. This paper first proposed specific superposition scope and calculation method for projects within river courses. Compared with the previous single calculation of backwater and scouring, it more truly, accurately reflect the actual situation of projects within river courses.

Abstract. The streamflow of the Yellow River is strongly affected by human activities of irrigation and dam regulation. Many attribution studies focused on the long-term trend of discharge, yet the contributions of these anthropogenic factors to streamflow fluctuations have not been well quantified. This study aims to quantify the roles of irrigation and artificial reservoirs in monthly streamflow fluctuations of the Yellow River from 1982 to 2014 by using the global land surface model ORCHIDEE with a new developed irrigation module, and a separate offline dam operation model. Validation with obsevations demonstrates the ability of our model in simulating the main hydrological processes under human disturbances in the Yellow River basin. Irrigation is found to be the dominant factor leading to 63.7 % reduction of the annual discharges. It might lead to discharge increase in the summer if irrigation is widely applied during a dry spring. After illustrating dam regulation as the primary driver affecting streamflow seasonality, we simulated the changes of water storages in several large artificial reservoirs by a new developed dam model, which does not require any prior knowledge from observations but only implements two simple operation rules based on their inherent regulation capacities: reducing peak flows for flood control and securing base flows during the dry season. Inclusion of dams with this simplified model substantially improved the simulated discharge by at least 42 %. Moreover, simulated water storage changes of the LongYangXia and LiuJiaXia dams coincide well with observations with a high correlation value of about 0.9. We also found that the artificial reservoirs can affect the inter-annual fluctuations of the streamflows, which however was not reproduced faithfully by our dam model due to lack of annual operation rules. From the mismatches between simulations and observations, we inferred the potential impacts of multiple medium reservoirs and five large irrigation districts (e.g., the Hetao Plateau), which were ignored in most previous hydrological studies.

The root-stones loss for flood control project is serious in the Lower Yellow River, and the tetrahedron-like concrete penetrating frame is a new protection technology. The Experiment on preventing root-stones loss of flood diversion and regulation works in Taohuayu with tetrahedron-like concrete penetrating frames in the Xingyang reach of the Yellow River. The experiment results show that: (1) the technology of tetrahedron-like concrete penetrating frame is simple, and it can make root-stones very steady; (2) the tetrahedron-like concrete penetrating frame can effectively reduce the depth of scour holes in front of dam and slow the direct impact of water flow on the dam body; (3) the tetrahedron-like concrete penetrating frame can effectively reduce root-stones loss and save lots of stones; (4) the tetrahedron-like concrete penetrating frames could be made use of for the project foundation stabilization, and they are thrown into the slope of root-stones and the riverbed outside slope toe within a certain width to increase the effect of root-stones protection better.

The effective reservoir sediment regulation measure is extremely significant for the sedimentladen river. It should not only extend the reservoir life, but also pose favorable conditions for the management of the river-reservoir system. Especially, the remarkable changes in the hydrological processes challenge to the system in some respects, like flood control, rive training, ecological environment improvement and so on. This paper gives a brief discussion on the representative existing problems in Ningxia-Inner Mongolia reach of the Yellow River. The water-sediment parameters and artificial regulation factors are then summed through a comprehensive literature review. Then we investigate the response to the different scales of floods in the Inner Mongolia reach through a three-dimensional model, in which the simulation region is from Bayangaole gauging station to Toudaoguai gauging station. With respect to the riverbed deformation, it is effective to control the relationship between the incoming water and sediment to restrain the shrinkage of the main channel; and surely that there exists a nonlinear relationship between channel scouring and incoming water-sediment conditions. Through data analysis and simulation results, the response characteristics of different watersediment regulation boundary conditions can be obtained, such as the ratio between sediment concentration and discharge, the discharge duration and the discharge, which is favorable to further water-sediment regulation of the reservoir and the management in Ningxia-Inner Mongolia reach of the Yellow River.

Based on the project construction and investment feature of the Downstream of Yellow River, the structures were divided into flood control dike, water diversion, irrigation and water saving, soil erosion conservation and ecological projects, river mouth management and development and water resources information. Using fuzzy and decision making analysis theory and project planning investigation data, the different project weights were calculated and fuzzy ideal point model was set up. According to administrative region, the total area of the downstream of the Yellow River was divided as 14 sub-regions. Using the model to solve the project construction sequence, the sequence scheme of the water project construction was achieved. The results have an important significance for the different water projects construction of the downstream of the Yellow River.
