Research on Water Quality Improvement Method Based on Slowly-Stored and Quickly-Released System in Xi'an Moat
Published 2023-01-01“…The slowly-stored and quickly-released system was studied to explore the method of optimizing the hydrodynamic force of rivers in arid regions and reveal its effect on water quality.The south-west tributary of Xi'an moat was defined as the study area.A hydrodynamic force-water quality coupling model of the moat was built based on the collected data of current water quality and hydrodynamic force by using MIKE21.In the coupling model,the impounding gate was designed based on the dam body of the moat to simulate the scouring and silting capacity of the lower reaches caused by rapid discharge from the upper reaches of the channel.The influence law of rapid discharge at different water levels and water quality conditions on hydrodynamics and water quality of the moat was studied.The numerical simulation results from MIKE21 show that water level has a significant influence on the hydrodynamic force,and water quality has a significant influence on the pollutant concentration.The simulation results of the hydrodynamic force-water quality coupling model of the moat show that the working condition with a 1-meter water level and class Ⅲ inlet water quality can greatly improve the water quality and hydrodynamic force of Xi'an moat.By using the water reaching the standard of the class Ⅲ inlet water quality as the supply source,the water quality of Xi'an moat can be effectively improved by enhancing the hydrodynamic force of the moat.…”

Structure and formation of the Lower Cretaceous–Eocene section in the central part of the Simferopol Uplift
Published 2022-06-01“…The results obtained show that the Valanginian–Early Hauterivian silty and sandy deltaic deposits of the regressive sedimentation phase are concordantly overlapped by a transgressive sequence formed (from bottom to top) by sandy sediments of the coastal shallows, interlayering middle ramp clayey silts and sands, and outer ramp clays. Above the unconformity, a break of at least 70 Ma was registered from the Early Hauterivian to the Late Ypresian. …”

Effect of Flow Direction on Relative Permeability Curves in Water/Gas Reservoir System: Implications in Geological CO2 Sequestration
Published 2017-01-01“…This is because of the notion that flow in subsurface formations is usually in horizontal direction and that vertical flow is impossible or marginal because of the impermeable shales or silts overlying them. The density difference between two fluids (usually oil and water) flowing in the porous media is also normally negligible; hence gravity influence is neglected. …”
