The choice of the objects was determined by the morphometric features of the water bodies, their remoteness from the sea, and the possible anthropogenic load on them. The main hydrochemical characteristics were determined, including the temperature, electric conductivity/TDS, pH, color, alkalinity, ionic composition, hardness, and the concentrations of oxygen, hydrogen sulfide, organic carbon, nutrients, heavy metals, and methane. Water hardness was found to be low with chloride and sodium ions dominating in its TDS. The hydrochemical conditions are shown to be generally favorable for biogeochemical processes. At a low and medium concentration of organic mater (from 8 to 30 mg/L), humic acids dominated in its composition, determining a higher color index of water (except for the Nizhnii Pert Lake). By their trophic level, the examined lakes were classified as oligotrophic (one of them is dystrophic), mesotrophic, and eutrophic. The anthropogenic load determined the status of a mesotrophic water body, and the high trophicity was determined by natural factors (the swampiness of catchment areas and their relatively recent separation from the sea).</p>","PeriodicalId":49368,"journal":{"name":"Water Resources","volume":"11 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140574935","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 degree of pollution was estimated using the Shannon and EPT indices, as well as the Woodiwiss index, an indicator that partially takes into account the first two indices. It is shown that the selected parameters decrease downstream of the sources of anthropogenic impact, thereby reflecting a decrease in the species diversity of benthic biocenoses and a decrease in the number of indicator species sensitive to pollution. Small streams are particularly affected; pools are subject to greater transformations than riffles. An integrated indicator of water quality based on biological parameters is proposed. It was used to rank all studied areas by the degree of pollution. It is shown that ten of the 23 studied river areas are assigned to the 1st class of water quality (conventionally clean areas), seven areas to the 2nd class (weakly polluted areas), three areas to the 4th class (dirty areas), and three areas to the 5th class (extremely dirty areas). This indicates that, despite multiple sources of pollution, the Ural River has a high self-purification capacity and most of the studied areas are quite clean and favorable for the habitation of benthic invertebrates.</p>","PeriodicalId":49368,"journal":{"name":"Water Resources","volume":"123 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140574922","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}

In the literature, many studies have been conducted to estimate drought indices over time. In this study, drought forecasts were made for the Seyhan and Ceyhan Basins in 3-, 4-, 6-, and 12-month periods with the Standardized Precipitation Index (SPI) using precipitation data between January 1989 and July 2020.

Lixia River Watershed, a relatively closed low-lying polder area in the lower reaches of Huai River basin, China, is closely related to the Yangtze River system. The spatio-temporal variations of water quality of Taizhou, a subsection of the Lixia River Watershed, were assessed based on the monthly water quality data of 39 sampling sites in 2017, by combining methods of Water Quality Index of the Canadian Council of Ministers of the Environment (CCME WQI), cluster analysis (CA), discriminant analysis (DA) and principal component analysis (PCA). The results show that CCME WQI ranged from 70.17 to 95.35, and the water quality of sampling sites could be grouped into 3 categories, where the southwestern parts of both Hailing and Jiangyan were excellent, the south and northeast of Xinghua were good, the southeast of Jiangyan and the northwest of Xinghua were fair. The 12 months of 2017 were grouped into two clusters, water quality in time period 1 (January to March, July to October) was poor, while that in time period 2 (April to June, November to December) was good. Sampling sites were grouped into two clusters: spatial group A (southwest of both Jiangyan and Hailing, south of Xinghua) and spatial group B (southeast of Jiangyan, north of Xinghua), and spatial group B was seriously polluted. NH<sub>3</sub>-N, total phosphorus (TP) and five-day biochemical oxygen demand (BOD<sub>5</sub>) were the major variables responsible for water quality variation, while permanganate index (COD<sub>Mn</sub>), chemical oxygen demand (COD<sub>cr</sub>) and dissolved oxygen (DO) were the secondary parameters.</p>","PeriodicalId":49368,"journal":{"name":"Water Resources","volume":"10 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140574925","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}
