Generally, flow discharge is computed using the rating curve (RC) established from the relation of flowrate and water level stage. Determination of the parameters of the rating curves are subject to the uncertainties related with difficulties and limitation of the flow monitoring to cover the wide ranges of flow variation. Especially at the river confluences, the uncertainties pronounces when flood occurs due to several factors such as roughness change, backwaters, and levee overflow. The Seomjin River basin in Korea suffered from flood inundation occurred at the tributary confluence during the extreme flood in 2020. In identifying the reliable flow rate of the main stream and tributary, this study proposed an indirect flow assessment scheme using a 1D hydrodynamic simulation model to find the best-simulated water level in an iterative manner based on the Monte Carlo (MC) simulation. With a large number of discharge data generated from the random number combination, it is possible to find the best results automatically by specifying the reliability limitation considering the uncertainty of the pre-determined RC parameters associated with the roughness coefficient. Nash Sutcliff-efficiency (NSE) was incorporated to evaluate the reproduced water level to meet the threshold specified for NSE ≥ 0.75. The simulated flowrates computed from the revised RC and roughness coefficients revealed error ranges of 8% ~ 36.6% compared with the design flood. The approach proposed in this study is applicable to determine the valid parameters necessary to create a revised RC at the existing water level gauge station where the uncertainties of the RC are pronounced especially in the vicinity of the channel confluence","PeriodicalId":505267,"journal":{"name":"Environmental Research Communications","volume":"14 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139854357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With a growing distance between agriculture and the public, communicating changes and fostering public acceptance as crucial factors for the success of these changes has become challenging. Therefore, understanding public attitudes towards emerging system changes in unfamiliar sectors helps identify appropriate communication strategies and provides information about possible responses from different stakeholders. To address the scarcity of studies on system changes in agriculture and their acceptability, a multidimensional evaluation of attitudes was undertaken using a factorial survey to test the utility of value-congruent information for enhancing positive attitudes. Electrical field cultivation (EFC) served as a case example for one potential energy system change in agriculture. The data were collected via an open scientific survey panel in Germany (N = 300) using a written vignette in the form of a newspaper article; different benefit foci and hypotheses were tested using path analysis. Although the different benefit foci did not reveal significant differences, problem awareness and knowledge were found to predict positive attitudes toward EFC. For once, results highlight the need to foster overall problem awareness for fossil fuels to garner public support for various pathways. Additionally, results underscore the perceived lack of personal affectedness by transition pathways as a barrier to responding to communication strategies, specifically in unfamiliar sectors such as agriculture. The study outlines the need for stakeholders to design communication strategies under consideration of fostering personal affectedness and overall problem understanding.","PeriodicalId":505267,"journal":{"name":"Environmental Research Communications","volume":"57 36","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139683755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we collected and analyzed 54 samples of groundwater and upstream stream water within the Nam Mu River basin in Lai Chau province during the dry season. These samples underwent thorough analysis for physicochemical parameters, major ion concentrations, and trace elements. Some results revealed a close relationship between streamwater and groundwater, indicating a similar chemical composition. These waters could be classified based on geological formations, yielding two primary water types in the area. The first type, characterized by Ca2+ - Mg2+ - HCO3- is prevalent in Triassic terrigenous sediments. The second type is a mixed water type, ranging from Ca2+ - Mg2+ - Cl- to Ca2+ - Na+ - HCO3-, primarily distributed in Permian felsic volcanic formations. These distinct water types are primarily the result of interactions between water and rock, precipitation processes, and ion exchange phenomena. Geochemical simulation results demonstrated the supersaturation of aragonite, calcite, and dolomite minerals, leading to the precipitation of carbonate minerals. Concurrently, the simulation indicated a tendency to dissolve minerals such as fluorite, gypsum, halite, and sylvite. The assessment of water quality using the WQI indicates that, in accordance with QCVN 01-1:2018/BYT 2018 standards, the majority of groundwater and streamwater are suitable for domestic use. However, exceptions exist in certain sample locations where water quality exceeds permissible standards, primarily due to elevated levels of Fe, Mn, and NO3- concentration. Hence, it is important to implement water treatment processes for the water sourced from these specific locations before their utilization in daily activities to ensure the safety and well-being of the local population.","PeriodicalId":505267,"journal":{"name":"Environmental Research Communications","volume":"67 20","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139526646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional approaches are expensive and are limited to developed countries. Phytofiltration using fast-growing trees and shrubs like willows potentially offer an alternative. This paper aims to determine if wastewater treatment using phytofiltration can provide complementary environmental and economic benefits for rural communities in a Nordic climate such as the province of Québec, Canada. It looks at different perspectives of the wastewater treatment solution in a local and rural context. Based on life cycle analysis (LCA) and life cycle cost analysis (LCC), we found that, for an exemplar Québec municipality, the conventional wastewater treatment scenario impacted more on climate change, ecosystem quality and human health than the two phytofiltration of wastewater scenarios studied, where impact is highly dependant on the biomass valorization. The net present cost of the phytofiltration scenarios were lower than typical conventional treatment in Québec. For a biomass producer, conventional biomass production had the highest environmental impact on ecosystem quality, while biomass production from phytofiltration had the highest environmental impact on climate change, human health, and resources. We demonstrate that the phytofiltration is a viable and multifunctional technology that could provide good incentives for a local biomass value chain. it allows to both alleviate wastewater treatment burden and provide affordable biomass for bioenergy development for rural communities. Mobilizing local stakeholders will be key to make phytofiltration an alternative solution for both environmental burden alleviation and rural economic development.","PeriodicalId":505267,"journal":{"name":"Environmental Research Communications","volume":"54 36","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139441888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
