“…The piedmont boundary, with an altitude of about 50 m above seawater level and regarded as the hydrogeological boundary of Zone I and Zone II, was delineated mainly based on the geomorphological map of the NCP . This line is close to the middle diversion route for the water transfer project from the Yangtze River to the NCP (Wang and Ma, 1999). Environmental impacts are to be expected on the regional groundwater flow in these two zones.…”

“…Since serious water shortages have occurred in the last 20 years, three schemes were planned to divert water from the Yangtze (Changjiang) River to the NCP, with design diversion capacities of 8Ð85 ð 10 9 m 3 year 1 , 2Ð3 ð 10 10 m 3 year 1 , and 2Ð0 ð 10 10 m 3 year 1 (Liu and He, 1996;Wang and Ma, 1999;Qiang and Zhang, 2001). The eastern route was initiated in 2002.…”

Abstract:The North China Plain (NCP) is an important agricultural area in China and has a high population density. Serious water shortages have occurred in this region over the last 20 years. Water transfer from the Yangtze River (the east route) was initiated in the year 2002 to provide water for the major cities of the NCP. This study was carried out before the implementation of the water transfer project, focusing on the spatial integration of the groundwater flow system and geochemical characteristics, which are mainly controlled by tectonics, geomorphology, and lithology. The field survey and the geochemical analyses of the groundwater samples indicated that the groundwater in the NCP has a two-layer structure, with a boundary at a depth of about 100-150 m. The two layers differ in pH, concentrations of SiO 2 and major ions, and isotopes ( 18 O, deuterium and tritium (T)). Chemical components in the upper layer showed a wider range and higher variability than those in the lower layer, indicating the impact of human activity. The flow direction of the groundwater in the upper layer was examined in detail in two profiles, showing that the upper layer flows east towards the Cangzhou-Daming fault, while the groundwater in the lower layer flows northeast towards Tianjin. Three hydrogeological zones are identified: recharge (Zone I), intermediate (Zone II), and discharge (Zone III). The recharge zone was found to be low in chloride (Cl ) but high in T. The discharge zone was found to be high in Cl and low in T. This may be due to the difference in groundwater age. The discharge zone was subdivided into two sub-zones, Zone III 1 and Zone III 2 , by considering the effects of human activities. Zone III 2 was strongly affected by water diversions from the Yellow River. As groundwater flows from the recharge zone to the intermediate and discharge zones, chemical patterns evolve in the order: Ca-HCO 3 > Mg-HCO 3 > Na-Cl C SO 4 .

“…As a boundary condition for the model, the fraction of water available for allocation has been defined as 9.5 km 3 =year minus 7.4 km 3 =year for the 100 major cities in the north (Wang and Ma 1999). The remaining 2.1 km 3 =year were distributed evenly to the arable land of the NCP and the share available to Ziya was found.…”

Water scarcity and rapid economic growth have increased the pressure on water resources and environment in Northern China, causing decreased groundwater tables, ecosystem degradation, and direct economic losses due to insufficient water supply. The authors applied the water value method, a variant of stochastic dynamic programming, to optimize water resources management in the Ziya River basin. Natural runoff from the upper basin was estimated with a rainfall-runoff model autocalibrated using in situ measured discharge. The runoff serial correlation was described by a Markov chain and used as input for the optimization model. This model was used to assess the economic impacts of ecosystem minimum flow constraints, limited groundwater pumping, and the middle route of the South-North Water Transfer Project (SNWTP). A regional climate shift has exacerbated water scarcity and increased water values, resulting in stricter water management. The results show that the SNWTP reduces the impacts of water scarcity and impacts optimal water management in the basin. The presented modeling framework provides an objective basis for the development of tools to avoid overpumping groundwater resources at minimum costs.

Abstract:The North China Plain (NCP) is one of the places where the groundwater is most over-exploited in the world. Currently, our understanding on the spatiotemporal variability of the cones of depression in this region is fragmentary. This study intends to simulate the cones of depression in the shallow aquifer across the entire NCP during the whole period from 1960 to 2011. During the simulation, the dominant role of anthropogenic activities is emphasized and carefully taken into account using a Neural Network Algorithm. The results show that cones of depression in the NCP were formed in 1970s and continuously expanded. Their centers were getting deeper with an increasing degree of groundwater exploitation. This simulation provides valuable insights for developing more sustainable groundwater management options after the implementation of the South-to-North Water Diversion Project (SNWDP), which is a very important surface water project in China in the near future. The numerical model in this paper is built by MODFLOW, with pumpage data completed by neural network algorithm and hydrogeological parameters calibrated by simulated annealing algorithm. Based on our long-term numerical model for regional groundwater flow in the NCP, one exploitation limitation strategy after the implementation of SNWDP is studied in this paper. The results indicate that the SNWDP is beneficial for groundwater recovery in the NCP. A number of immense groundwater cones will gradually shrink. However, the recovery of the groundwater environment in the NCP will require a long time.Water 2013, 5 678
