This has led to develop and adopt new technologies for more constructive and efficient waste management system so as to reduce the pressure of solid waste management on the authorities as well as on environment. The initial step in the solid waste management is landfill site selection which is quite complex as it implicates many environmental factors. Suitability of the selected site is always accountable for loss or gain of the environment in the future and also it determines the economics and benefits or loss. Hence, it is always advisable that suitability should be determined considering economical and socio-environmental factors. This paper throws a light on the viability of new geospatial technologies like remote sensing and geographic information system (GIS) in the process of site selection for municipal solid waste in Calangute/Saligao, Goa, India. For the current study, Weighted Overlay Analysis is used to identify the suitability of the site. The research work identifies the arability of land for disposal of MSW in a systematic manner that ensures the environmental protection and management of waste products. This study provides the suitable dumping sites for municipal solid waste, which may be subjected to the green city management and city planning. Thus, this study provides an advance way to manage the solid waste of an urban area. This study expresses the efficiency of model-based technique that can help to deal with a burning issue like MSW across the globe. This model-based study can reduce laborious activities, minimize the cost of the project. Thus, it helps an urban planner to for better site selection for MSW management and overall city planning. This study will provide a base line for future study like leachate management, land degradation, loss of biodiversity, etc.","PeriodicalId":143718,"journal":{"name":"Journal of Environmental Informatics Letters","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116308667","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}

The prediction of time-dependent soil behavior over the entire year and under extreme weather conditions is required for the design and construction of buried infrastructure. The main contributions of this research are the development and validation of a coupled soil-atmosphere interaction model to predict transient water and heat movement under mean, extreme dry, and extreme wet weather scenarios. Results indicated that the hydraulic properties are governed by the net water flux that resulted in the shifting of the seasons as follows: mean that comprises winter (3½ months), spring (1 month), summer (5½ months), and fall (2 months); dry that includes spring (4 months), summer (4 months), and fall (4 months); and wet that has winter (4 months), inseparable springsummer (5 months), and fall (3 months). The thermal properties are governed by air temperature for the investigated soil. Identical values of thermal gradient during spring-summer (April to October) in all scenarios indicate that the soil gains more heat compared with the heat loss during fall-winter (November to March), especially for mean and dry conditions. Furthermore, the inflection points in heat flux show that the soil gains heat from May to August and loses heat from September to April. Finally, the active depth of soil was found to be 4 ± 1 m for hydraulic properties and 3 m for heat flux.","PeriodicalId":143718,"journal":{"name":"Journal of Environmental Informatics Letters","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125350981","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}

Triplicate samples of demersal marine fish species and sediments were collected from five stations (fishing ground) and analysed for heavy metals [mercury (Hg), cadmium (Cd), and lead (Pb)] and metalloid [arsenic (As)] using ICP-OES (inductively coupled plasma optical emission spectrometry) adopted USEPA 200.7 standard method. The metals/metalloid concentrations in demersal fish species and sediment fell below the FAO/WHO permissible limits and sediment quality guidelines (SQG) [probable effect level (PEL) and threshold effect level (TEL)]. The ecological indices [probable contamination index (PCI), mean effect level quotients, newly modified hazard quotient (mHQ), and hazard quotient (HQ)] revealed low contamination level of heavy metals in sediment. The hazard index (HI) of metals in fish species associated with human health fell below the recommended threshold of 1 with no significant health risk to the consumers. The target cancer risk (TCR) of Cd and Pb in the fish species were below the regulation range of 1.0 × 10−6 to 1.0 × 10−4 set by the USEPA. The cluster analysis revealed two clusters. Cluster 1 (C1) showed that Cd was significantly accumulated in the sediment. Cluster 2 (C2) showed significantly low bioaccumulation of Hg, Cd, Pb, and As in fish species across all stations. The ecological and health risk assessment indices generally established low potential adverse effect on demersal marine fish species due to the overall low ecological severity risk associated with heavy metals/metalloids in sediment. Hence, consumers of fisheries resources from western off Nigeria coast are relatively safe from being exposed to any non-carcinogenic and carcinogenic health risk.","PeriodicalId":143718,"journal":{"name":"Journal of Environmental Informatics Letters","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125564457","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}
