Embodiment Construction

[0052] The present invention proposes a parameter identification method for small reservoirs without data, which not only identifies the range of the reservoir area and the elevation of the weir crest, but also provides a method for determining and verifying the discharge parameters and discharge curves of the reservoir, and then identifies the operation mode of the reservoir , providing technical support for flood discharge of small reservoirs and flood control of small watersheds in areas without data.

[0053] Combine below figure 1 , figure 2 and image 3 , the present invention is further described:

[0054] Step 1), determine the reservoir area and weir crest elevation of the small reservoir without data, and the storage capacity of the small reservoir without data does not exceed 1 million m 3 , the reservoir adopts a flood discharge structure without gate control, and the elevation of the flood discharge weir is the normal water storage level of the reservoir; no d...

Abstract

The invention relates to a data-free small reservoir parameter identification method combining hydrological simulation and continuous remote sensing images. The method comprises the following steps: step 1, determining a data-free small reservoir area and an upstream basin range; step 2, reservoir discharge parameters and a discharge curve are determined; step 3, verifying the reservoir dischargeparameters and the discharge curve; and step 4, identifying the reservoir operation mode. The data-free small reservoir parameter identification method provided by the invention not only identifies the reservoir area range and the weir crest elevation, but also provides a reservoir discharge parameter and discharge curve determination and verification method, thereby identifying the reservoir operation mode, and providing technical support for small reservoir flood discharge and small basin flood control in a data-free area.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, specifically a method for identifying parameters of small reservoirs without data combined with hydrological simulation and continuous remote sensing images, which is mainly used for flood forecasting of small reservoirs in areas without data, flood forecasting of small watersheds under the influence of water conservancy projects, and small reservoirs. Flood risk assessment and early warning work. Background technique [0002] Since the founding of New China, my country's water conservancy projects have developed rapidly, providing guarantees for flood control, water supply, irrigation, power generation, and shipping. At present, my country has built 9,685 small and medium-sized sluices, 93,850 small reservoirs, and 39,685 ponds and dams that threaten the flood control safety of villages in mountain torrent disaster prevention and control areas. The distribution of small wa...
