Landslide mass and materials eroded along the path may be deposited along the channel(s) and subsequently remobilised; in other cases, runoff and debris mix inside the channels or nearby the protective structures.

Selected scenarios are presented for a case study in Southern Italy with a discussion provided on how solid concentration of flow-like mass movements evolves in a mountain catchment. Numerical results show that at first, the runoff water accumulated within the natural channels and then a debris flow propagated rapidly down the slope meanwhile the concentration of solid material decreased due to the addition of runoff water and a hyperconcentrated flow reached the foothill area, later even more diluted and capable to move several kilometres far until it almost reached a railway line.</p></div>","PeriodicalId":500,"journal":{"name":"Bulletin of Engineering Geology and the Environment","volume":"84 6","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10064-025-04283-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143919032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study proposes a debris flow susceptibility assessment method based on the Convolutional neural network (CNN)-bidirectional long-short-term memory neural network (BiLSTM)-attention mechanism (CNN-BiLSTM-attention) deep learning model that combines geographic information technology and artificial intelligence algorithms. The study area is the Xiaojiang River watershed in the Yunnan-Guizhou Plateau, a region prone to frequent debris flows. First, a debris flow conditioning factor system and a debris flow sample set are constructed using multi-source data, including remote sensing, geological, and precipitation data, with the watershed unit as the assessment unit. Second, the geoDetector method is adopted to explore the optimal combination of conditioning factors. Finally, the CNN-BiLSTM-Attention model is applied to quantitative analyze debris flow susceptibility, and its performance is compared against three deep learning models and three machine learning models. The findings are summarized as follows. Lithology, elevation difference, average slope, 24H maximum precipitation, average elevation, average modified normalized difference water index (MNDWI), Melton ratio, average land surface temperature (LST), and channel gradient are the dominant factors influencing the debris flows development. The prediction performance of CNN-BiLSTM-Attention is significantly better than that of the other six models. Its area under the receiver operating characteristic curve (AUC), accuracy (ACC) and mean absolute error (MAE) reach 0.903, 0.953 and 0.165 respectively, demonstrating excellent prediction accuracy and generalization performance.

Railway ballast is essential for maintaining the stability and durability of train infrastructure. The requirement for this material is driven by the increasing need for efficient transportation networks induced by the growing population and rapid urbanization. More evidence of the need for a sufficient supply of ballast comes from the development of high-speed rail initiatives and the upgrading of current rail networks. To meet this demand, environmentally-conscious sourcing methods and creative approaches to addressing environmental issues are needed, meanwhile maintaining the dependability and effectiveness of railway networks worldwide. Millions of tons of mining waste consisting of various components are produced annually by phosphate extraction activities, including those at the Benguerir mine in Morocco. Ballast materials are often composed of higher quality igneous or metamorphic rock; this work is unique for its novel approach to study the possibility of manufacturing railway ballast aggregates from sedimentary-origin mining waste. The three hardest lithologies -flintstone, phos-flint, and dolomitic limestone- are the subject of this study. A comprehensive assessment was conducted, including: (i) petrographic characterization, (ii) environmental and health behavior analysis, (iii) geometric requirement verification, (iv) physical characterization, (v) chemical and mineralogical evaluation, (vi) geotechnical analysis, and (vii) durability tests.

Extensive studies on the seismic-induced liquefaction of calcareous sands have been conducted, but none have examined its characteristics of blast-induced liquefaction. Therefore, this study conducted a series of experimental and numerical investigations on the characteristics of blast-induced liquefaction in saturated calcareous sand sites. Field explosion tests were carried out on saturated calcareous sand sites with different scaled burial depths. Subsequently, liquefaction analysis models were constructed using the nonlinear dynamic analysis software LS-DYNA and were validated against measured stress waves. The numerical results indicated that the variation in pore water pressure (PWP) was consistent with the shock wave pattern, exhibiting a significant peak. Based on the numerical calculation results, empirical formulas for blast-induced liquefaction in saturated calcareous sands were established. Finally, the parameters analysis revealed that, under the same scaled burial depth, the stabilized PWP increased with the charge weight, and the liquefaction zone increased with the explosive charge. Under the same explosive equivalent, the accumulated area of excess pore water pressure (EPWP) decreased with the increase of explosive scaled burial depth. At the same scaled burial depth, the liquefaction impact range remained essentially the same across different charge weights. Enhancing the compactness of calcareous sands can improve its resistance to blast-induced liquefaction.</p></div>","PeriodicalId":500,"journal":{"name":"Bulletin of Engineering Geology and the Environment","volume":"84 6","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143908662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A systematic experimental approach was adopted to analyze the effects of varying cycle numbers (<i>n</i>), joint wall compressive strengths (JCS), roughness parameters (<i>r</i>), and normal stresses (<span>({sigma }_{n})</span>) on degradation.

Two distinct failure mechanisms are observed: shear-off and wear, with wear failures becoming dominant as the number of cycles increases. A predictive shear strength model incorporating the weakening effects of WDCs is developed using regression analysis, achieving a mean relative error of 5.41%, thus validates its reliability.

Moreover, these methods start from LSIs but ignore the nonlinear correlation between known landslides and LSIs. To address this, the natural break-frequency ratio (FR) method is proposed, combining the natural break method for LSLs division with the FR method. First, the five conventional methods divide LSIs predicted by three machine learning models in An’yuan County, China. Then, the natural break-FR method is proposed to divide the same LSIs and compared with these methods. The natural break-FR, equal interval and K-means method yielded the largest sum of landslide ratio in very high and high susceptibility level, showing these methods can use high and very high susceptibility levels to predict as many landslides as possible. Finally, statistical perspectives of known landslide identification, division area proportion, and landslide ratio are applied to discuss how to select a suitable division method.

The landslide ratios of equal interval, K-means, and natural break methods at high and very high susceptibility levels are greater than the former methods.
