A Study on the Mechanism of the Precipitation-Induced Slope Instability of Colluvium

Applied Sciences, Journal Year: 2025, Volume and Issue: 15(4), P. 1933 - 1933

Published: Feb. 13, 2025

In this study, the evolution process of a landslide model under continuous rainfall conditions with intensity 30 mm/h is studied in depth based on an outdoor test colluvial slope as research material. The response law pore water pressure and settlement amount also obtained, influence bedrock inclination angle development deformation failure discussed. When dip 40°, it prone to sudden slip-type landslides, follows: tensile cracks appear at trailing edge, these continue increase, leading overall sliding. 30°, traction landslides are occur, there sliding foot slope, middle, occurs upper part, Before starts, rises significantly. evolution, fine particles move rainwater, larger greater number that accumulate higher elevation scale edge body during

Calculation of Urban Groundwater Environmental Carrying Capacity Driven by Multiple Factors

Water, Journal Year: 2025, Volume and Issue: 17(6), P. 807 - 807

Published: March 12, 2025

Global urbanization has led to the overexploitation and pollution of groundwater resources, restricting sustainable construction development cities. Groundwater environmental carrying capacity (GW-ECC) refers maximum total amount pollutants that can be accommodated by a given system within certain time period under specified goals. To better understand changes in GW-ECC context rapid urbanization, this study built model urban driven multiple factors. Taking area Zhengzhou as an example, rainfall infiltration riverside seepage were calculated considering change impervious over past 20 years. The Mann–Kendall rank test was used evaluate varying trends two factors process. Based on this, current year calculated, different regulatory schemes after 10 years evaluated. results showed constructed could accurately simulate system. With acceleration recharges precipitation, rivers tend decline. ammonia nitrogen exhibited overall upward trend. By end 2030, is expected reach 1964.5 t. Changes resources caused precipitation extraction main driving variations GW-ECC. In areas with mature measures such increasing recharge reducing are more effective improving

An Automated and Efficient Slope Unit Division Method Coupled with Computer Graphics and Hydrological Principles

Applied Sciences, Journal Year: 2025, Volume and Issue: 15(9), P. 4647 - 4647

Published: April 23, 2025

Slope units serve as fundamental spatial for surface morphology modeling and multidisciplinary coupling analysis, holding significant theoretical value practical implications in regional stability assessments, process simulations, quantitative geological engineering research. The scientific delineation of slope must simultaneously satisfy implementation requirements adhere to the unit homogeneity principle. However, conventional like hydrological analysis method (HPAM) exhibits critical limitations, including strong threshold dependency, a low automation level, single-attribute optimization, thereby restricting its applicability complex scenarios. Based on principles consistency processes, this study integrates computer graphics algorithms with simulation techniques propose an automated division coupled (SUD-CGHP). employs digital elevation model (DEM) input data construct three-stage hierarchical framework comprising (1) terrain skeleton extraction through morphological erosion algorithm, (2) topological relationship iteration (3) multisource parameter constraints. This achieves without thresholds while enabling multi-attribute fusion effectively addressing shortcomings HPAM. Field validation Yanglousi Town, Hunan Province, demonstrates that SUD-CGHP-generated exhibit superior internal flow direction, aspect, gradient compared HPAM maintaining complete topographic–hydrological connectivity. research findings indicate significantly enhances validity delineation, providing reliable modeling.
