About 70% of the world's water withdrawl is used for agriculture, and irrigation water accounts for more than 90% of the total water consumption. Due to varied irrigation water sources, irrigation facilities, and crop planting types, there is large spatial heterogeneity in irrigation water use. Irrigation water can be consumed by evapotranspiration or stored as soil water in the root zone soil layer, while the portion exceeding the saturation zone will recharge groundwater. The complexity of irrigation processes above makes it extremely difficult and challenging to estimate irrigation water use. Based on the soil water balance under irrigation, formulas to estimate irrigation water use (IWU) were deduced by us, considering multiple processes of irrigation (evapotranspiration, root zone soil moisture, and deep percolation). Remotely sensed and modeled actual evapotranspiration, modeled root zone soil moisture were used in our approach to generate the monthly IWU across the continental United States during 2000-2020 at a high spatial resolution (1 km). The results show that our approach has the mechnism to characterize multiple irrigation processes and can obtain IWU data with excelent accuracy at high spatiotemporal resolution.

Landslide drainage and seepage prevention is a common technology for the treatment of landslide source area in Qinghai Tibet Plateau. The existing siphon drainage technology is inefficient when applied to high altitude areas. Through improvement, a variable pipe diameter and high head siphon drainage technology is proposed to solve the deep drainage problem of landslide in high altitude and low pressure areas. 12 groups of siphon drainage tests with variable pipe diameter were carried out to verify the correctness of the theoretical velocity calculation formula. The test results show that the theoretical calculation results of siphon velocity are in good agreement with the test results, and the relative error of theoretical calculation is within 5%; Different schemes of variable pipe diameter increase the siphon flow rate by 15% - 116%. It can be seen that variable pipe diameter can significantly enhance the drainage capacity of siphons, especially for high lift siphons.

Zhangye basin mainly includes 20 irrigation areas. Under the restriction of water diversion, the surface water consumption of the irrigation area is under control, but the groundwater exploitation is increased, resulting in the groundwater level drop in the middle reaches, resulting in potential ecological environment risks. Due to the complex and frequent exchange of surface water and groundwater in the study area, it is possible to realize the overall water resource saving by optimizing the utilization ratio of surface water and groundwater in each irrigation area. In this project, on the premise of not changing the water demand of the middle reaches irrigation area, the two problems of maximizing the outflow of Zhengyi Gorge (given groundwater reserve constraint) and maximizing the outflow of Zhengyi Gorge (given groundwater reserve constraint) are studied.

Data Overview: Zhangye's channels are divided into five levels: dry, branch, bucket, agricultural and Mao channels, of which the agricultural channels are generally unlined. Mao channels are field projects, so the three levels of dry, branch and bucket channels and a small part of agricultural channels are mainly collected. The irrigation canal system data includes 2 main canals (involving multiple irrigation districts), 157 main canals (within a single irrigation district), 782 branch canals and 5315 dou canals, with a total length of 8, 745.0km. Data acquisition process: remote sensing interpretation and GPS field measurement are adopted for data acquisition of irrigation canal system. Direct GPS acquisition channel is the most effective method, but the workload of GPS acquisition channel is too large, and we only verify the measurement in some irrigation areas. The main method is to first collect the manual maps of irrigation districts drawn by each water pipe. Most of these maps have no location, only some irrigation districts such as Daman and Shangsan have been located based on topographic maps, and some irrigation districts in Gaotai County have used GPS to locate some channels. Referring to the schematic diagram of the irrigation district, channel spatial positioning is carried out based on Quikbird, ASTER, TM remote sensing images and 1: 50000 topographic maps. For the main canal and branch canal, due to the obvious linear features on remote sensing images and the general signs on topographic maps, it can be located more accurately. For Douqu, areas with high-resolution images can be located more accurately, while other areas can only be roughly located according to fuzzy linear features of images and prompt information of irrigation district staff, with low positioning accuracy. Each water management office simultaneously provides channel attribute data, which is one-to-one corresponding to spatial data. After the first draft of the channel distribution map is completed, it is submitted twice to the personnel familiar with the channel distribution of each water pipe for correction. The first time is mainly to eliminate duplication and leak, and the second time is mainly to correct the position and perfect the attribute data. Description of data content: The fields in the attribute table include code, district and county name, irrigation area name, channel whole process, channel name, channel type, location, total length, lined, design flow, design farmland, design forest and grass, real irrigation farmland, real irrigation forest and grass, water right area, and remarks. Code example: G06G02Z15D01, where the first letter represents the county name, the 2nd and 3rd numbers represent the county (district) number, the 4th to 6th characters represent the trunk canal code, the 7th to 9th characters represent the branch canal code, and the 10th to 12th characters represent the dou canal code.
