<p> Yang Hui explained, Yuyao lying north to south, "North platoon" There are natural difficulties, such as to drainage, can only increase the pump intensity discharge. But in the "Buffett" during this typhoon,nike air force, flood tide coincided with the northern gate in October 7, 8,air max pas cher, 9,moncler homme, the culmination of three days up to 8.1 meters.</p>
<p> small-scale; at the same time, in 1998 planned Yaojiang two gates, it has yet to open. Meanwhile, the Yongjiang River basin also in a special location, during the typhoon, very easy to form typhoons,louboutin pas cher, heavy rains and tide,barbour femme, "three meet", outside the tide for a long time at a high position, making seawater intrusion inland. Yao River drainage resistance also comes from "natural rival" - Fenghua River. During the flood,nike sito ufficiale, the Fenghua River floods and flood Yao Jiang's "competition" into the Yongjiang, but Yao Jiang Yao River flood gates required prior to discharge into Yongjiang, Fenghua River and the mouth of the Yongjiang no gate,chaussure giuseppe zanotti, more fast. Under the influence of these three factors, Yao Jiang Xiangdong drainage situation deteriorate further. The typhoon, "Buffett", October 8,tn, at the highest tide level Yaojiang gates once reached 4.81 meters, and the water level on the gate flat, almost impossible to drain. In fact,christian louboutin pas cher, in order to improve the discharge capacity of Yuyao, when there is insufficient "East row" capability, the local water system to try to develop new ways of flood - "North row." 1992, "Yao River Basin Integrated Planning Report," 1998 "Yongjiang River Basin Integrated Planning Report" in the main planning tasks are: flood, flood, drought Kaneharu to waterlogging focus. Planning methods include decentralized governance, providing additional to the north of Hangzhou Bay drain outlet; building a database flood; low-lying areas around the dike and other electrical discharge. However.</p>
<p> when the rainfall is 524 mm,woolrich outlet, the highest water level 4.8 m, flooded for 13 days. "The heavy rainfall disaster did more than 50 years ago." Ningbo hydrological station owners Yang Hui told the "China News Weekly", in addition to rainfall, drainage difficult main reason Yuyao special geographical location, and Yao River downstream poor drainage. Yuyao is hilly south,hollister italia, the north coastal plain, lying in the middle of the zonal original. Yaojiang River from west to east from the city through, while the north and south several tributaries converge on Yao River. Locals call this special terrain structure called "pot", Yuyao happens in the "pot" position, regardless of the south or the north floods occur, the final will converge to the "bottom of the pot," Yao River,escarpins louboutin soldes, Yao River Basin if there are floods, the situation is even more critical. Historically, Yao River drainage has been relying on "East row" flood. According to the 2004 "Ningbo City, water conservancy Chi",scarpe hogan outlet, Yao River drainage area of 1934 square kilometers,louboutin france, a total length of 107.4 kilometers. Yao River from west to east, and Fenghua River merged into Yongjiang,jordan 5 retro, finally flowing into the sea. However, from 2002 onwards, local government and Hangzhou-Ningbo Canal Waterway by four standard transformation of Yao River took straightened, the length has been shortened. Yang Hui analysis,air jordan 4, history of the formation of multi-channel is curved, and Hangzhou-Ningbo Canal for many rivers to take straightened, widened approach to shipping brings convenience, but also play an active role in local flood,peuterey donna, but bigger flood area, it may cause more violent Yao River upstream water potential,nike air max outlet, increased water. For faster drainage, will be on the East row exert a greater pressure. However, in the waterlogged, and Yao Jiangdong row it has also been a tremendous resistance. Yuyao WCB to "China News Weekly," explained one of the resistance is the only outlet Yao River basin east row: Yaojiang gates. Yao River Sluice was built in 1959, a total of 36 holes, hole width of only 3.3 meters.</p>
