3. In view of the shortage of land resources, complex river network and water system in the core area of the Yangtze River Delta and the requirements of the Yangtze River Protection for the water quality of the incoming river, the "one area, two ends, one line" ecological environment system management model adapted to the river network waters with strong human activities, and the river network ecological environment restoration technology of estuary+backbone river+capillary branch river+lake "point-line-surface" collection are innovatively put forward, which ensures the water quality of the Yangtze River discharged from Xingou River north and the ecological health of the basin;
4. A new type of bidirectional tubular pump with S-shaped blades and bidirectional inlet and outlet channels were developed, which solved the problem of improving the hydraulic efficiency of the ultra-low-lift bidirectional pump device, and a high-power two-speed motor was developed by using pole-changing technology, which improved the efficiency of the pump unit under the condition of wide variable lift and effectively reduced the energy consumption of the pump unit.
The research results of this project have been applied to the whole process of construction planning, design, construction and management of Xingou River diversion and drainage project, effectively serving the management of water conservancy, transportation, environmental protection and other industries and relevant government decisions, and achieved remarkable results.

Project introduction
In recent 20 years, there have been bank collapses in many sections of Jiangsu section of the Yangtze River, and the water level has repeatedly exceeded the warning water level, setting a new record for the highest water level in history, which seriously threatens the flood control safety, shipping safety and river regime stability in our province. River regulation projects such as bank protection and slope protection are the main ways to maintain stability in the rapidly changing area of the Yangtze River regime. Under the background of the great protection of the Yangtze River and the construction of ecological civilization, how to improve the implementation effect of the bank slope protection project and ensure the construction quality of the project is of great significance for maintaining the stability of the coastline and ensuring the safety of flood control.

This paper reveals the response mechanism of erosion and deposition changes in a single sand pit to other projects, and puts forward a simulation method to accurately predict the riverbed to reach a stable state.
3. The panoramic view of the dike is obtained by using the sounding technology combining ground penetrating radar and multi-beam, and the complete shape of the dike is constructed by registration; The multi-temporal point cloud of dike is used to analyze the deformation of dike, and the feasibility of using point cloud for dike monitoring is clear. Based on fuzzy system and neural network theory, a deformation-based safety evaluation model of dike engineering is constructed. The deformation analysis software of point cloud is developed, and the three-dimensional change analysis of point cloud and the visual view of the results are realized.
4. The failure mechanism and process of geo-reinforced turf are proved, and the influence law of geo-materials and reinforcement technology on impact resistance is obtained; Through numerical simulation and field test, the erosion variation laws of two kinds of geo-reinforced turf at different flow rates are explained. A water erosion test system was designed to reveal the hydraulic erosion resistance characteristics of mixed turf. The in-situ sampling method of three-dimensional geo-reinforced turf was established, and the combined reinforcement effect of geo-mat, plant root system and soil was expounded.
