“…Thereinto, the annual water storage is the total value of reservoir storage, soil storage and groundwater storage. According to the remote sensing monitoring results, the reservoir surface area of the Haihe River Basin decreased gradually during the period of 1964-2004 (Lu et al 2012), so did the reservoir storage. Because most of the reservoirs are distributed in the upstream area and basin scale soil water storage generally is assumed not to change over an annual cycle (Gebreyohannes et al 2013;Xue et al 2013), the upstream water storage change is considered to be a change in reservoir storage, and the downstream water storage change is assumed to be mainly the result of a change in groundwater storage.…”

“…The Haihe River is the largest river system and stretches between 111.96°E and 118.48°E longitudes and between 35.00°N and 41.61°N latitude, and is composed of the Jiyunhe, the Chaobaihe (including Chaohe and Baihe Rivers), the Beiyunhe and the Yongdinghe Rivers in the north of the basin. The Daqinghe, the Ziyahe, the Zhangweihe and the Heilonggangyundong Rivers are in the south of the basin (Lu et al 2012). The total area of the basin is 232,000 km 2 , of which hills and plateaus (upstream) make up 142,900 km 2 or 62 %, while lowland plains (downstream) comprise 89,100 km 2 or 38 % of the area.…”

“…In the upstream area thousands of reservoirs were constructed and a large part of the region was protected by soil and water conservation measures (HWCC 2000;ECWRSUP 2004;Zhang et al 2010;Lu et al 2012). Many flood discharge waterways and irrigation projects were built in the downstream area (EBHR 1997).…”

“…The Haihe River Basin, one of the seven largest river basins in China, has suffered water shortages in the last 30 years (Xia et al 2006;Ma et al 2010;Chu et al 2010a, b;Wang et al 2011a, b;Lu et al 2012). In the 1950s the water resources of the basin were very abundant.…”

In the last 50 years, the hydrological system of the Haihe River Basin in northern China has undergone great changes, such as declines in runoff and discharge, rivers drying up, and groundwater depletion. Both climate variability and human activities have been regarded as causes for these changes, but which is the major reason was not clear in the past. This paper aims to quantify the impact of climate variability, particularly changes of precipitation, and human activities (water storage projects, agricultural development, soil and water conservation projects, and agricultural water saving) on the hydrological system of the basin. A basin-level water consumption balance model was used to simulate the changes of the hydrological system during the period of 1958-2008. The non-parametric Mann-Kendall test and Pettitt's test methods were adopted to identify trends and change points of the hydrological factors. And the contribution of climatic variability and human activities was calculated based on the multi-year average of all the climatic and hydrological parameters of different river basin management stages and their relative changes between adjacent periods. The results show that from 1958 to 1965 the basin hydrological system was in the natural state of equilibrium. During 1966-1978 human activities were the main factors with the contribution of 96.1 and 76.6 % for the upstream and downstream area. During the period of 1979-1988, the change of precipitation was the main factor to cause the upstream and downstream hydrological system changes with contributions of 73.8 and 64.1 %. In the period of 1989-2000 and 2001-2008, the climate variability still dominated the impact of the hydrological system changes in the upstream and downstream areas. Based on these findings, some measures were recommended to improve the balance of the hydrological system in this basin including recharging the downstream area with water that is currently stored in the upstream, implementing agricultural water-saving practices in the basin, and using treated sewage from the cities for river environmental flow recovery and wetland restoration.

“…In fact, the damming results in significant changes to the river ecological environment. For example, water recreational activities cut down the space for aquatic organisms (Jiang et al, 2006a(Jiang et al, , 2006bRohdea et al, 2006); water transfer projects change the spatial and temporal pattern of regional water resources (Zeilhofer and Rubem, 2009;); and reservoirs aggravate the degradation of water quality and the spread of water-borne diseases (Mukand et al, 2011;Lu et al, 2012). Considering these changes, modern reservoir management demands a new paradigm, which integrates ecological components into its management decisions (Camdevyren et al, 2005;Suen and Eheart, 2006;Cabecinha et al, 2009;Chen et al, 2011).…”

a b s t r a c tThis study proposes a self-adaptive GA-aided multi-objective ecological reservoir operation model (SMEROM) and applies it to water quality management in the Xiangxi River near to the Three Gorges Reservoir, China. The SMEROM integrates statistical water quality models, multi-objective reservoir operations, and a self-adaptive GA within a general framework. Among them, the statistical water quality models of the Xiangxi River are formulated to deal with the relationships between reservoir operation and water quality, which are embedded in constraints of the SMEROM. The multiple objective functions, including maximizing hydropower generation, minimizing loss of flood control, minimizing rate of flood risk, maximizing the average remaining capacity of flood control and maximizing the benefit of shipping, are considered simultaneously to obtain comprehensive benefit among the environment, society and economy. The weighting method is employed to convert the multiple objectives to a single objective. To solve the complex SMEROM, an improved self-adaptive GA is employed through incorporating simulated binary crossover and self-adaptive mutation. To demonstrate the advantage of the developed SMEROM model, the solutions through ecological reservoir operation are compared with those through the traditional reservoir operation and the practical operation in 2011, in terms of water quality, reservoir operation and objective function values. The results show that most of benefit in the ecological operation is better than that in the traditional or practical operations except for the hydropower benefit and loss benefit of flood control. This is because flood control and environmental protection are reasonably considered in the ecological operation.
