This study evaluated the spatial pattern, environmental hazard, and potential health hazard of 13 trace metals in water and sediment samples collected from the Johor River basin using multivariate statistical techniques in order to identify the impact of both natural and human-related factors on the presence of trace metals in the area. The increased levels of metals in Station S1 indicated a significant impact from municipal, domestic, and industrial waste. The Geo-accumulation Index (I_geo<span>) values for pollution and ecological indices in the sediment of the Johor River Basin ranged from -9.44 to 6.27. The Pollution Load Index (PLI) values ranged from 0.05 to 0.18, and the Potential Ecological Risk Assessment<span> (RI) values ranged from 2.15 to 11.18. These results indicate that the sediments in the Johor River Basin have a low risk of contamination from trace metals. The water's hazard quotient (HQ) had an average value of 0.0001, while the hazard index (HI) had an average value of 0.0003. It is important to increase stakeholders' understanding and concerns regarding the potential long-term human health and ecological implications associated with trace metals in Johor River water.

However, its application coupling with the Pressure-State-Response (PSR) framework for modelling wetland eco-hydrological state (EHS) is rare but it is necessary for wetland management and restoration. Dam-induced hydrological modification is a crucial driver of EHS change. How EHS conditions can control ecosystem services potentiality (ESP) including provisioning, regulating and cultural services is another vital unresolved issue that needs to be analysed for the well-being of the people. Considering this, the present study tried to model the EHS of wetlands in the Tangon River of India and Bangladesh blending both machine learning algorithms and PSR framework. It also aimed to assess the influence of EHS on ESP. Tangon River is a floodplain river, which is hydrologically intervened through the Boda dam in the Panchagarh district of Bangladesh, which causes hydrological modification in the river and riparian floodplain wetlands. All the applied models successfully explored that 28.90% to 47.89% of the wetland area under a very good EHS zone was reduced to 28.90 % to 31.41%, indicating the gradual degradation of EHS quality over a wider part of the wetland after hydrological intervention. The performance of the applied models is acceptable, but REPTree and Bagging models were found best-performing models for EHS modelling. This study also established that the EHS condition of the wetlands positively influences the ESP of the wetlands. So, improvement of EHS is a way forward for promoting the serviceability of the wetland.</div></div>","PeriodicalId":56070,"journal":{"name":"Ecohydrology & Hydrobiology","volume":"25 2","pages":"Pages 339-356"},"PeriodicalIF":2.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141393215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The RHS toolbox software has been updated with data from the Greek monitoring program which allowed for type-specific assessments using the Habitat Quality Assessment (HQA) score. The HQA scores from 366 monitoring sites were analyzed to identify spatial patterns and significant variations. Sites were classified in five HQA classes based on the position of their HQA score relative to sites of similar types. We also investigated whether Ecological Quality Ratios (EQRs) for three biological quality elements (benthic diatoms, benthic macroinvertebrates and fish) differed significantly among HQA classes. Correlations showed that sites at mid and high altitude catchments with natural land cover had better HQA scores than lowland sites with agricultural land cover. In addition, large urbanized districts (e.g. Attica), and central Greece displayed lower habitat quality than Epirus and Western Macedonia. Our findings revealed that EQR values varied significantly among the HQA classes, with these differences being more prominent for small and medium lowland streams.

Nevertheless, the operation of hydropower facilities is fraught with risks stemming from both natural phenomena and anthropogenic activities. Extreme weather events and suboptimal reservoir operations, for instance, can precipitate grave safety incidents. A case in point is the catastrophic explosion at the Sinanjiang (SNJ) hydropower station in Yunnan Province, China, on May 29, 2020. The incident inflicted significant human and financial tolls, revealing critical deficiencies in the station's safety protocols. This paper presents a comprehensive examination of the mishap, scrutinizing the influence of severe hydrometeorological conditions, reservoir water quality alterations, soil erosion, and reservoir management shortcomings on the event's occurrence. The investigation reveals that the primary cause of the disaster was the accumulation of high sludge concentrations within the reservoir, which, under specific meteorological conditions, led to methane gas reaching explosive levels. Additionally, the reservoir's declining water quality, prolonged drought conditions, and exacerbated soil erosion collectively exacerbated methane gas generation and accumulation. In light of these findings, the paper proposes an array of preventative and safety-enhancing measures tailored to hydropower station management. By implementing these recommendations, the aim is to elevate operational standards and forestall similar catastrophes. This research serves as a crucial alert for the global hydropower industry, emphasizing the imperative of vigilant safety governance to avert analogous calamities.</div></div>","PeriodicalId":56070,"journal":{"name":"Ecohydrology & Hydrobiology","volume":"25 2","pages":"Pages 406-413"},"PeriodicalIF":2.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141696810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
