This creates new anthropogeomorphic landforms which need documentation, along with assessing mining effects on the river water quality. Mining affected reaches in three rivers of West Bengal were studied and a classification of these anthropogeomorphic features was undertaken, based on their genesis from excavation (sand bar skimming and scooping), planation (sand bar levelling) or accumulation (sand piling) processes. Nomenclatures like sand bridges/tracks/roads, sand hollows and sand pools are suggested, while seasonal and yearly variations in their patterns and growth were mapped from Google Earth images. Results reveal that in a stretch of the Subarnarekha River, sand pools increased in number by 2.5 times during 2021–2022, while sand hollows doubled. The increase in total size of sand pools indicates more extensive mining, rising from 7650 m² in 2020 to 22477 m² in 2022 (almost tripling). Water quality indicators like turbidity and total suspended sediments were estimated for affected reaches from multi-year and multi-seasonal Sentinel-2A images via the Google Earth Engine platform using several indices. Field measurements of water quality parameters using a depth-wise YSI ProDSS sampler corroborated the image analysis and denoted the indices best representing actual conditions. Sand pools reported higher total suspended sediment (TSS) values, ranging between 250 and 450 mg/L, with values above 330 mg/L prevalent towards the end of the mining season in May. In contrast, open channel reaches have TSS values from 50 to 130 mg/L. During the peak mining period in January, reach-wise TSS values for all rivers ranged from 150 to 350 mg/L, with the extensively mined Damodar River reporting highest values (&gt;288.2 mg/L). Where river and mining site disconnections occur, the ambient riparian habitat degrades, resulting in the death of fishes as disconnected pools dry out. This study is possibly the first to classify such riverbed mining landforms and detect their changing patterns. It also measures relevant water quality parameters in mining affected reaches and highlights pertinent satellite image-based indices for the same, stressing on the need for greater ecological assessments of such sites.</div></div>","PeriodicalId":50850,"journal":{"name":"Advances in Space Research","volume":"77 3","pages":"Pages 2979-3002"},"PeriodicalIF":2.8,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146081820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studies have shown that the impact of ionospheric storms on space weather depends not only on the characteristics of the storms, but also on the time of day, season, geomagnetic and geographical coordinates, etc. This makes it relevant to study each unique geospace storm.
