Don't exclude the basin may occur
Don't rule out the possibility of flood happened basin
May 21, ChaiLinWan area in wuhan in hubei caidian, broad river water flowing meekly hanjiang river, Fake Oakley Dispatch the shore is bustling about the picture, the workers are the head, with dry QiShi nervously carefully. "Don't look now so gentle, once it has the XunQing rivers face immediately." Hubei province FangBan deputy chief engineer JiangYanSheng said, in 2011, the Yangtze river tributaries QiuXun influence hanjiang river, north river ChaiLinWan part BengAn happened to the danger, the threat caidian area and wuhan city flood control the flood safety group hanyang. "ZhuXunQi is coming soon, and to speed up SaoWei engineering problems, must, in accordance with the requirements of the DaXun to prepare for."
Such vigilance, is not an idle threat. With the arrival of the ZhuXunQi, recently, southern China region of guangxi, guangdong, guizhou, hunan, chongqing appear bigger range heavy rainfall process, local area in the serious disasters, for flood control and rescue was a wake-up call. From the office of information shows that this year the national DuoYuOu flood season than last year as a range of obvious, regional rainfall process more than normal slant, flood disaster may be heavier than last year, don't rule out the possibility of flood happened basin.
"This year the Yangtze river basin XunQing come early, more fierce, flood control and the grim situation," the Yangtze river flood control and drought relief headquarters of vice director of office of WuDaoXi said. According to introducing, the Yangtze river water flood season rainfall process this year more frequent, rainfall partial, water, YuanJiang, XiuShui information, lean river flood alert appear more than the tributary. The overall partial water, middle and lower reaches of high water level 1 to 3 meters, small reservoirs be or get out of danger, a serious loss disasters. The office ZhiHuiChang convened by the Yangtze river video conference points out, this year's the weather situation and in 1998 and 1954 is similar, the Yangtze river water levels remain high, at the same time, because of dozen years did not happen basin flood, when the Yangtze river flood chance is more and more big.
The huaihe river's flood control pressure will increase. Since 2007, the huaihe river is not happened the whole basin, it is predicted that this summer, northeast rainfall yellow two from fifty percent to. In addition, this year parts of southern happened since the year 1998, the biggest early ChunXun, according to hydrologic data analysis, our country is the year of ChunXun happened early, summer produced great flood. "The forecast and analysis shows that the huaihe river basin, this year may appear more serious flood disaster," the deputy director of the national FangBan ZhangGuTuan said.
One of the seven big rivers of the pearl river, the flood control situation also not optimistic. "We monitor flood season this year, according to the west of possible flooding, medium, dongjiang beijiang river may appear small flood by rain. Time and space, uneven regional, local influence appears serious drought disaster, flood more likely" pearl river water resources commission ShuiWenJu, deputy director of the LiuZhiSen said.
"With the rapid development of urbanization, industrialization and disasters caused losses of life and property and comprehensive social influence is bigger and can't afford to flooding, drought may not be." The office a head of the points out, Fake Oakley Flak Jacket for possible XunQing, must pay much attention, would rather believe its to have, suspect its no, would rather believe its big, suspect its small, further strengthen sense of anxiety and sense of responsibility, and based on the DaXun, do they might encounter.
Against floods have bottom spirit
Water conservancy project start girders, hydrological telemetry, material storage, rescue team, ready to go
For without sin rather, cannot sin without it. Faced with the possibility of the flood disaster, our coping ability?
Reservoir dyke is the key and flood control. "At present our country has built up river levees almost 300000 kilometers, reservoir 87800 seats, with a total capacity of 716.2 billion cubic meters, the flood storage and detention area 94 place, key, meanwhile, a large number of seepage path on the strengthening of problems, flood control capacity significantly increased," deputy minister of water resources LiGuoYing said.
"Big projects" start flooding in defense of the girders. The three gorges reservoir is the core of the Yangtze river flood control project, the three gorges reservoir flood season last year has four times by the flood control, reduce the total flood is about 28 billion cubic meters, greatly reduced the downstream pressure flood control.
"According to this year, the Yangtze river water rainfall regime specific office has asked the three gorges reservoir from May 7 up evenly into 0.5 meters away daily." WuDaoXi said, the three gorges reservoir is expected to the June 10 fall away to flood control limit water level 145 m, the capacity of the flood control suspension. At the same time, the Yangtze river flood control for the task of large and medium-sized reservoirs, the vast majority are located in the water level of flood control limit below the water level, to play the possibility of floods, for the Yangtze river flood security provided protection.
Before the flood disaster, not only have to deal with each of the basin "big", have more "meticulous live".
Hydrological telemetry is flood control and, with the coming of the flood season, hydrological people more busy. On May 20, the Yangtze river ShuiWenJu committee meteorological and hydrological YuBaoChu office, forecasters staring at the computer, analysis the data just received. "We will be responsible for receiving the whole basin 1600 water intelligence information, forecast the station sin covers an area of 140 square kilometers above." YuBaoChu, deputy director of ZhengJing said, currently has a basic control the Yangtze river the whole basin, hydrologic stations nets, 30 minutes can display the whole watershed information together. "With the meteorological satellite, radar and the application of high-tech, the prediction accuracy also is rising. To HanKouZhan, for example, water levels predict accuracy within 3 days has reached to 90% above."
The flood-fighting disaster relief, adequate materials reserve is the foundation. Last year, the country and an increase of 100 million yuan of the central flood control materials reserve, make its amounting to $300 million. "A numerical simulation materials are ready, gave the order, ready, participate in the shipment of rescue and relief, emergency rescue." May 22 afternoon, located in the central area in zhaoqing dinghu flood control and drought material warehouse, guangdong province is three materials reserve, director of the center LiRongLi said.
Walked into the warehouse, see piles, floodlight, fabric, generators, ChongFengZhou, inflatable, drainage emergency vehicle, sea rescue boat, etc. Various kinds of flood control amphibious chock-full of emergency supplies, many materials are already finished packing, mount the specified trailer, once a rescue immediately can allocate the output. Not only materials reserve enough, Fake Oakley Frogskins the corresponding dispatching plan also all available rooms. In flood season before coming, guangdong is three materials reserve center of the three special work
