Research on River Health Assessment of Hanjiang River Basin
Published 2023-01-01“…Health assessment of rivers and lakes is an important means of their health management.To meet the requirements of ecological civilization construction and river chief system in the new circumstances,this paper performs the classified assessment and comprehensive evaluation of the Hanjiang River Basin from five aspects:hydrological integrity,morphological and structural integrity,chemical integrity,biological integrity,and the sustainability of social service function according to the relevant methods in the Technical Guidelines for River and Lake Health Assessment (SL/T 793—2020).The assessment results show that the Hanjiang River Basin is in a state of health overall,and the score of the main stream of the Hanjiang River is slightly higher than that of its tributaries.The hydrological integrity and biological integrity of the sub-criterion layer are weak,which leads to the ecological conditions in a state ranging from sub-health to health.The social service function of the sub-criterion layer is sustainable,and the functional status is in the state of health.The health assessment of rivers and lakes in the Hanjiang River Basin is of great significance to promote its water resources protection and water environment management and ensure the sustainable utilization of its water resources.…”

Joint P- and S-Wave VSP Traveltime Tomography via Well Log-Guided Physics-Informed Neural Networks
Published 2025-01-01“…Since the original PINNtomo loss function relies on multiplicative-factor eikonal equations that depend on background traveltimes based on uniform velocities at the source location, we introduce a source-independent multiplicative decomposition of the eikonal equation to eliminate this velocity dependence. …”

Study on the peak shaving operation of cascade hydropower stations based on the plant-wide optimal curve
Published 2025-09-01“…This study proposes a novel method to enhance RES and hydropower utilization through: 1) Establishing a plant-wide optimal output-water level-outflow relationship curve based on the output-head-flow relationship and the flow-head loss and outflow-tailwater level relationship curves for each unit; 2) Developing a short-term peak shaving model for cascaded hydropower stations that incorporates wind and PV power which defines minimum coefficient of variation of residual load as objective functions, and improving discrete differential dynamic programming successive approximation (DDDPSA) method to solve it; 3) Analyzing the peak shaving capacity of the cascade hydropower station by varying water consumption for power generation. …”
