This paper presents three examples of remarkable gravity-driven processes in Czech slate mines—flexural toppling, rockfall, and sinkhole collapse—that have developed within broader geosystem interactions. These failures were investigated through field inspection, speleological mapping, and geological analysis. Dendrogeomorphological survey of flexural toppling at the Kunz Mine provides unique, pioneering data on the historical development of this type of gravitational failure. Rock mass failure and subsequent collapse depend not only on long-term factors—such as mineral composition, geological structure, topography, and methods of underground excavation—but also on current environmental conditions, including water and airflow, humidity, freeze–thaw cycles, and mineral weathering. The resulting cascades of weathering and erosional processes repeatedly drive the mines into states of instability. To better understand the chain of processes leading to the loss of stability equilibrium, it is therefore essential to consider the broader spatiotemporal relationships among the individual landscape features in which the abandoned mines are embedded.</p></div>","PeriodicalId":542,"journal":{"name":"Environmental Earth Sciences","volume":"85 15","pages":""},"PeriodicalIF":3.3,"publicationDate":"2026-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12665-026-13110-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148838303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study develops a GIS-based multi-criteria decision analysis (MCDA) framework combined with Analytic Hierarchy Process (AHP) weighting to evaluate quarry suitability in the West Region of Cameroon. Geological, environmental, topographic and infrastructural criteria were integrated using GIS-AHP to generate a regional quarry suitability model. An additional methodological contribution is the introduction of a suitability density metric, which transforms pixel-based suitability outputs into administrative-unit indicators, enabling interpretation of quarry potential in relation to governance and planning units. This allows identification where suitable rocks occur and where they are spatially concentrated within communes and divisions. Results show that high and very high suitability zones are concentrated in the central-eastern crystalline belt, controlled primarily by granitoid-orthogneiss lithologies, moderate terrain conditions, and reduced environmental constraints. Sensitivity analysis indicates that the spatial pattern is robust under ± 20% perturbations of key AHP weights, although class proportions vary moderately. Field validation at 44 sites confirms broad agreement between regional predictions and quarry-scale observations, while also highlighting scale-dependent mismatches driven by local structural conditions and access constraints. The suitability density metric identifies Foumban as the primary exploration hotspot, with Foumbot, Massangam, Malantouen, Bangangté, Djebem and Bafoussam II as secondary priority communes. Magba is dominated by moderate suitability but still retains localized quarry potential. Overall, the framework provides a transferable screening tool for dimension stone prospectivity and supports spatially informed governance of low-value construction minerals in Precambrian terranes.</p></div>","PeriodicalId":542,"journal":{"name":"Environmental Earth Sciences","volume":"85 15","pages":""},"PeriodicalIF":3.3,"publicationDate":"2026-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12665-026-13100-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148837880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite their importance, integrated assessments of groundwater recharge potential and intrinsic aquifer vulnerability remain limited. This study assessed groundwater recharge potential and intrinsic aquifer vulnerability to contamination in the Sunyani West Municipality, Ghana. Groundwater recharge potential was mapped using a GIS-based Analytical Hierarchy Process (AHP) integrating seven hydrogeologically relevant factors (geology, geomorphology, slope, soil type, land use/land cover, drainage density and lineament density), while intrinsic aquifer vulnerability was evaluated using the F-HYDRA model based on flow accumulation, hydraulic conductivity and land use/land cover. All datasets were standardised to a spatial resolution of 30 m. The selected criteria represent key controls on infiltration, structural permeability and surface–subsurface connectivity within the Birimian crystalline basement terrain. The resulting recharge map delineated five recharge potential classes, with high and highest recharge zones occurring as discontinuous patches across the Municipality rather than being confined to a single area. A spatial consistency assessment using borehole yield data from 102 boreholes showed a positive association between recharge index and borehole yield (R² = 0.7863), although borehole yield also reflects aquifer transmissivity, weathering, fracture connectivity and well characteristics. The vulnerability assessment identified moderate vulnerability as the dominant class, while high to very high vulnerability occurred mainly in the northern-central and eastern parts of the Municipality. Nitrate concentrations measured from 20 boreholes exhibited a positive spatial association with the intrinsic vulnerability index (R² = 0.7435), although the relationship also reflects contaminant loading and local hydrogeological conditions. The integrated assessment identified areas where relatively high recharge potential coincides with elevated intrinsic vulnerability, highlighting priority zones for groundwater protection and land-use planning. The integrated AHP–F-HYDRA approach supports groundwater management in data-scarce crystalline basement environments, while recognising that recharge potential and intrinsic vulnerability represent relative spatial indices.</p></div>","PeriodicalId":542,"journal":{"name":"Environmental Earth Sciences","volume":"85 15","pages":""},"PeriodicalIF":3.3,"publicationDate":"2026-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12665-026-13070-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148837878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A road crossing the gully temporarily intercepted the mudflow and acted as a dam before it breached. Thus far, the influence of this dam’s blockage and collapse on the mudflow movement remains unclear. Based on field investigations and satellite imagery, we analyzed the landslide-mudflow evolution and simulated its transport and deposition processes using the Massflow software. Results based on different simulation scenarios revealed that the dam breach increased the mudflow peak velocity by approximately 30%. However, this velocity amplification effect attenuated rapidly downstream, and was mainly confined to the transport zone. The water input from a pond (~ 1,000 m²) upstream of the dam may have played a more important role in causing the long runout of the mudflow by increasing its water content.

It is of great significance to clarify the mutual feedback mechanism between land use and ecosystem services (ESs) to break the high-carbon lock and realize the synergy of ecological development. Based on the land use data from 2003 to 2023, this study takes Hohhot-Baotou-Ordos-Yulin urban agglomeration as the research object, coupled with PLUS-InVEST model, analyzes the temporal and spatial evolution characteristics of carbon stock, habitat quality, water yield and soil conservation, and weighs the synergistic relationship. Further set four scenarios of natural development, economic priority, green low-carbon and high-quality development to simulate the land use pattern and ESs response in 2033. On this basis, the driving factors of ESs are identified by using the geographical detector model based on the optimal parameters. The results show that: (1) The area of construction land increased sharply from 2003 to 2023, and the transfer effect between grassland, cultivated land and unused land was significant; (2) ESs is differentiated in stages, with carbon stock, habitat quality and soil conservation evolving in an inverted“U”shape, and the water yield continues to decline. The high-value areas are concentrated in ecological restoration areas, and the low-value areas are highly overlapped with industrial, mining and urban construction areas; (3) In the historical period, ESs was dominated by synergy, and soil conservation was significantly coordinated with carbon stock and habitat quality, while the negative balance between habitat quality and water yield was a typical feature of the study area, and it only showed a weak mitigation trend with the promotion of ecological restoration; (4) Scenario simulation shows that high-quality development scenarios can achieve ESs collaborative promotion, which is the best way to give consideration to ecological protection and double carbon targets; (5) Natural factors (precipitation, slope, evapotranspiration) determine the basic pattern of ESs spatial differentiation, and human factors such as GDP and population strengthen the trade-off/synergy effect between services through land development and urban expansion. This study reveals the high sensitivity of ESs in resource-based cities to land use change, which can provide scientific basis for land space optimization and ecological restoration policy formulation under the goal of “dual carbon” in similar areas.</p></div>","PeriodicalId":542,"journal":{"name":"Environmental Earth Sciences","volume":"85 15","pages":""},"PeriodicalIF":3.3,"publicationDate":"2026-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12665-026-13090-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148837440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
