Results show that although forests can reduce flow mobility, preferential flow paths may develop along trees, leading to ineffective energy dissipation along the flow flanks. For fine-grained flows composed of sand, the deposition behaviour is governed by the normalised slope angle and the transverse blockage ratio. For coarse-grained flows composed of gravel, the deposition and retention are controlled by two distinct jamming mechanisms: frontal deposit-induced jamming and arching-induced jamming. Frontal deposit-induced jamming occurs in all jamming cases, whereas arching-induced jamming only develops when tree spacing is smaller than three times of the grain size. We capture this variety of phenomena within two phase diagrams for fine-grained and coarse-grained flows. The phase diagrams provide a direct screening rule for minimum tree density and slope condition required to ensure jamming for a given grain size distribution.</div></div>","PeriodicalId":11567,"journal":{"name":"Engineering Geology","volume":"364 ","pages":"Article 108613"},"PeriodicalIF":8.4,"publicationDate":"2026-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146146831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Excellent agreement between model prediction and experiments was observed, demonstrating reliable extrapolation across mineralogical heterogeneity.
