1 Water Resources Overview Jiyuan City is located in the northwestern Henan Province, Taihang, Wangwu mountains, the territory of the Yellow River and its tributaries Qinhe, pythons and so on. Is a temperate continental monsoon climate, the average annual rainfall of about 670mm. In 1998, the total groundwater resources in Jiyuan City was 214.389 million m 3, the total surface water resources was 186.199 million m 3, the repeated calculation between groundwater and surface water was 135.429 million m 3, and the total water resources in 1998 was 265,153,000 m ~ 3. In recent years, the utilization of water resources has been quite large, and the total amount of water resources has drastically decreased. Most of the water quality is good, low salinity, suitable for farmland irrigation and drinking water for human and livestock, but due to the urban area
