Within nine years out of ten in the period from 1992 to 2001, oil products were not found there; however, since 2003, their annual mass transported every year rose above 2.5 thousand t. Therefore, the authors analyzed the available integral data on this river pollution and launched a screening study of the pollution of its tributaries. The obtained results confirmed the assumption regarding an abrupt growth: the pollution in 1992–2001 was many times less than that in 2002–2021. The transport through the outlet section increased from <1500 to 6400 t/year (the mean value). This pollution is supported by the major portion of tributaries in a considerable segment of the river. Field studies suggest a conclusion that the total input of oil products into the Kamchatka R. can reach 30–40 thousand t per year. A study of the effect of a plugged exploration well shows that it is a source of oil pollution. The number of permits issued over 28 years for exploratory drilling in one of the areas, a significant part of which is located in the Kamchatka River basin, reliably correlates with the mass of oil products transported through the outlet section. Therefore, the inflow of oil into water from exploration wells may be among the main causes or the main cause of the jump-like growth of pollution. Such results were obtained using several integral approaches, including an effective one—establishing a relationship between the natural and administrative characteristics. In order to reduce the pollution of one of the largest spawning rivers in Russia, it is necessary to continue studying, to carry out mapping its main sources, and subsequently eliminate them.</p>","PeriodicalId":49368,"journal":{"name":"Water Resources","volume":"148 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140885278","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 flood occurred in the year 2019 was one amongst the worst floods in the known history of the river basin. The accurate estimation of water level from flood model plays a major role in flood assessment. Various software packages are available for developing flood models. Selecting suitable software package is difficult task. So, the objective of present study is to test the performance of 1D hydraulic models for the Panchganga River Reach (PRR) in Kolhapur, Maharashtra, India. These hydraulic models are prepared by using Hydrologic Engineering Center’s River Analysis System software and MIKE HYDRO River software. These models are developed for the PRR situated between the Prayag Chikhali and Nursingwadi gauging stations. The developed models are calibrated and validated by using peak discharge events and flood events. The results revealed acceptable water level simulations made by both models. It is concluded from the study that both the developed models can be utilized by the concerned river management authority to understand water level fluctuations, which is needed for countering flood disaster.</p>","PeriodicalId":49368,"journal":{"name":"Water Resources","volume":"22 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140884936","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 effect of natural water chemistry on the sensitivity to a model toxicant (potassium dichromate) was evaluated for three laboratory test objects—unicellular algae Scenedesmus quadricauda (Turh.) Breb., crustaceans Daphnia magna Straus, and fish Poecilia reticulata Peters. The sensitivity of test objects was assessed by the values of median lethal (for daphnia and fish) and median effective (for algae) concentrations of the model toxicant, obtained with the use of the water samples as media for the preparation of test solutions of the toxicant. It was shown that, under the conditions of complex anthropogenic pollution, including an increase in TDS, the sensitivity of Daphnia magna and Poecilia reticulata to the standard toxicant was generally within the standard range for each test object, while in the case of Scenedesmus quadricauda, almost all obtained values of median effective concentrations were above the standard range (the sensitivity was lower). Statistically significant correlation was found between the median lethal concentration for Daphnia magna and a complex of interrelated hydrochemical characteristics, including TDS. The observed differences in the changes in the sensitivity of test-objects are presumably due to changes in water hardness. It is noted that the decrease in test object sensitivity under the effect of changes in water ionic composition can lead to overestimation of the maximal permissible concentrations, which are established with the use of natural water for water bodies, taking into account their natural features. The obtained results can be used in the formation of methodological approaches to regional standardization.</p>","PeriodicalId":49368,"journal":{"name":"Water Resources","volume":"20 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140889892","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 decrease in the concentrations was due to the degradation of low-molecular hydrocarbons.

The oil origin of the hydrocarbons in the sediments of the Bezymyannyi Creek and the rivers of Daldykan and Ambarnaya is confirmed by their high content of alkylied naphthalene homologues.
