The index was built using the method developed by the Jones dos Santos Neves Research and Development Support Institute to score the indicators and determine the comparative aspects in the Complexo do Alemão slums, using comparative spatial analysis. This methodology made it possible to assess that within a territory considered vulnerable in terms of sanitation, there are regions that are more fragile due to basic sanitation problems, and that this data is correlated with socio-economically more unfavorable areas, making it possible to structure the assessment of this type of vulnerability. On average, the partial index of lack of access to water was 0.34, the partial index of sewage collection was 0.28 and the glocal index was 0.31, classifying the Complexo do Alemão slums in the extreme lack range. This approach corroborated the validation of the sanitation deprivation index with information on the territorial scale of communities faced with the risk caused by unequal access to the human right to sanitation.","PeriodicalId":14063,"journal":{"name":"International Journal of Hydrology","volume":"185 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140457347","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 integrated approach to the hydrochemical investigation of streams and aquifers in drylands is essential owing to their distinctive climate, notably, low rainfall and high temperature. Studies on water quality in arid and semi-arid areas using multivariate analysis and water quality indices were scrutinized. Results showed that the hydrochemistry of streams and aquifers is controlled by both the natural geogenic processes and anthropogenic activities. However, in-depth understanding of geochemistry and land use types, as well as climatic vagaries, is required, to be able to discriminate these processes, since several ions of rock minerals origin are increasingly being added into the environment through human activities. While the sources of solutes and processes controlling the hydrochemistry of streams and aquifers can be established through application of multivariate analysis, this technique is limited in water quality investigations since it cannot measure the suitability of water for domestic, agriculture and industrial uses. Thus, an integrated approach incorporating water quality indices in conjunction with multivariate analysis is required. This is essential owing to the fact that the suitability of water for various uses is central to any hydrogeochemical investigation in arid and semi-arid environments. Thus, it is expected that future hydrochemical studies would apply this approach.","PeriodicalId":14063,"journal":{"name":"International Journal of Hydrology","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74554992","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}

This study examined the socio-economic impacts of wetland conversion on residents of Port Harcourt municipality. Data were sourced from both primary and secondary sources. Four (4) out of the twenty-four (24) reclaimed wetland sites were purposively selected for the study. The cross-sectional research design was used since there was no manipulation of the variables under investigation. A sample size comprised 280 heads of households from the eight proximate communities within the four selected reclaimed sites. The study revealed that wetland conversions have both positive impacts on residents of the study area. On a positive note, wetland conversion is a means of increasing land space for needed physical development and the provision of urban goods and services. The negative impacts of wetland conversion include the destruction of sources of livelihood for the people, the destruction of natural heritage and aesthetic areas and the destruction of conservation areas among others. The study advocates for the adoption of a sustainable wetland management strategy with an emphasis on the wise use of wetland resources to ensure the continued existence of wetlands in their pristine state, as this is the only way we can preserve the services that wetland provides to the survival of the human environment.","PeriodicalId":14063,"journal":{"name":"International Journal of Hydrology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82754521","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}

To achieve the proposed objective, the main factors presented in debates and discussions that occurred between master's and doctoral students, and researchers from government agencies in Brazil from 2021 to 2023 were monitored and recorded. The analysis of the challenges related to precipitation data collection in Brazil points to the lack of investment in the maintenance and monitoring of meteorological stations, the lack of observational data in certain regions of the country, the need to consider the spatial and temporal variability of the data, and the guarantee of the safety of the stations. To overcome these challenges, a joint effort is proposed by the government, the scientific community, and the general population with adequate investments in the maintenance and monitoring of meteorological stations, the adoption of more efficient solutions for data collection and analysis, the consideration of the spatial and temporal variability of the data, and the adoption of security measures for meteorological stations.","PeriodicalId":14063,"journal":{"name":"International Journal of Hydrology","volume":"413 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79963751","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}

By using last version of a tool to assist in pumping test interpretation suggested by the French Mining and Geological Survey, Transmissivity parameter values of confined aquifers were determined through the well-known Theis method. In the same approach, critical yield value of borehole was determined at the equivalence point of linear and quadratic pressure drop from short-term pumping test data. Geostatistical analysis and kriging of transmissivity of aquifers were realized. Then, it was elaborated few predictive equations between hydrodynamic and hydraulic parameters based on their relationship level. Comparison of aquifers productivity and boreholes hydraulic capacity ended the methodology. Transmissivity ranged from 9.10-7 to 4.10-5 m2.h-1 while specific yield of boreholes reached between 0.34 and 23.07 m3.h-1. Yields from exploited boreholes varied between 0.5 m3.h-1 and 12 m3.h-1 with an average reaching 3.44 m3.h-1. Critical yield varied between 2.11 and 18.8 m3.h-1 with an average of 6.95 m3.h-1. According to geostatistical analysis of Transmissivity, its spatial spreading adjusted spherical model with a range reaching 0.13 meters. Findings highlighted 44 % of aquifer areas characterized by low value of transmissivity with great value of exploited outflow. That suggests a short-term availability of drinking water for living communities. In the same way, 11.11 % of boreholes were established into aquifer areas characterized by great transmissivity and low outflow values that suggests a better supply environment with long-term groundwater availability.","PeriodicalId":14063,"journal":{"name":"International Journal of Hydrology","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85055194","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}
