Mode of Reservoir Flood Control Operation

) And the problems caused by poor operation as a starting point to facilitate the practical purposes to be improved. Taken by reservoir water level to control the discharge amount of real-time, that is how much the water level reached, the limit is much on discharge reservoir, the reservoir discharge volume is based on changes in reservoir water level to control the stage, and finally back to Stage 1 water level scheduling state . This scheduling can satisfy the required scheduling,[link widoczny dla zalogowanych], reservoir operation and easy staff scheduling practical new method for example 3, the scheduling of Hebei 3.1 Gangnan Reservoir as an example the determination of operation mode for the first phase of this stage of scheduling 3.1.1 main sections of reservoir flood control level on the maximum allowable level. Gangnan Reservoir flood control level is divided into two, the main flood season Z ± a 192m,[link widoczny dla zalogowanych], time before August 10 (including the August lO days); post-season Z-l95m, time is August 11 ~ September l5 days . Therefore need to determine the maximum allowable level 2. (1) flood forecast period to determine the maximum allowable amount of discharge predicted the amount of the maximum allowable leakage. Use the two places compare the amount of allowable leakage. First, the maximum allowed reservoir downstream river discharge volume; first quantitative information more limited level of water discharge volume of the normal maximum allowed, whichever of small value. Gangnan Reservoir downstream river discharge capacity of design safety 3300m. / S, according to the actual survey review. The current capacity of the basic channel to meet the design standards. According to two flood control level 192m, 195m above the water quantitatively, the analysis and calculation, the maximum discharge amount of the corresponding reservoir was 812m / s and 2773m / s were less than the 2 vent to allow the maximum discharge amount of the lower channel. So they chose to allow the maximum anticipated discharge of the amount of 812m / s and 2773m. / S. ② Gangnan reservoir flood forecast period under the flood control headquarters office in Hebei Province in April 1993 reported to the National Civil Air Defense Office of the \10h, forecast accuracy 9O (Grade A). The mean value of the scheduling for 8h. Determined according to the above permitted maximum discharge capacity and forecast period, corresponding to 2 Gangnan Reservoir anticipated flood water level of the maximum allowable level, respectively, 192.58m and 196.69m. 3.1.2 The second phase of this stage of the data listed below are assumed data. Only describes methods used. Associated with the reservoir is not the actual water level / m193200203204207207.5 discharged reservoir volume / m's limit of 3,000 open vent vent vent limit of 400 (normal spillway opening 6m) open drain (open new spillway 3m) wide open regular spillway discharge opening j} 3.2 Scheduling step (1) June l5 reservoirs have discharge current (2) June 15 hearing on the formal, the reservoir water level 192.5m. Higher than the flood control level of the main flood season (192m) 0.58m. Waiting for the flood forecasting flood forecasting department (3) Upon receipt of a flood forecasting department forecast a flood, the reservoir operation of all relevant departments to launch the reservoir began to discharge flood channels, 8h, the reservoir water level is to limit water level l92m, just meet the flood (peak) to come. (4) flood (peak) arrived, according to pre-established way of Phase 2 scheduling scheduling. (5) After the flood, and then maintain the water level to 192.58m at August 10, if there is the 2nd, 3rd ... ... flood, scheduling repeat steps (3),[link widoczny dla zalogowanych], (4), (5) that be. (6) August 11 flood control reservoir water level rose to l95m, when the reservoir water level can be reached 196.69m, and then wait. L0 in the future if the August floods, reservoir operation is still repeated (3), (4), (5) step, but information from the limited water level and water level should be adjusted according to 195m, waiting for the water level to build to 196.69m above by _ scheduling means scheduling, in addition to stage 2 to facilitate the actual operation, but also to retain part of the flood water. To Gangnan Reservoir, the flood in case of I996 in the year immediately following the 1997 drought linked. May retain some water or 079 800 000 023 300 000 m m. This part of water for agriculture, particularly important. The existing 17 large reservoirs in Hebei Province (large I-4, large blocks I-l3), which predicted flood conditions l5 of Block. If these 15 reservoirs have changed this method scheduling, reservations for more than a year of drought, \Or 183 700 000 m, the water can make tens of thousands of hm good harvest the crops, the effect is significant. In addition. The scheduling scheme does not exist to change the basic operation program and reservoir flood control level over the issue,[link widoczny dla zalogowanych], but expected more scientific use of the time difference. Can be used to retain some of the flood of resources, to address the water shortage in north, also proposed a thought
