It proposed to characterize the intrinsic hydrodynamic parameters of the productivity and to know the influence of these on the productivity of the drillings. The hydraulic parameters of the catchment structures and the pumping test sheets were used to determine the hydrodynamic properties through a methodological approach integrating Cooper Jacob's empirical formulas and automated calculations using the Pumping Interpretation Assistance Tool (OUAIP). A standardized principal component analysis (ACPN) was used to analyze the correlation of the different parameters. The results obtained range over several orders of magnitude. The values of the specific flow oscillate between 0. 01 and 4.87m²/h while the transmissivity varies between 1.25E-07 and 7.34E-03 m².s-1. As for the critical flow, it is between 0.869 and 26.6 m3/h. These values indicate that the aquifers generally have low specific flow rates, but fairly good transmissivity. The Normalized Principal Component Analysis (ACPN) allowed to highlight the different productivity factors of the aquifers in the region: water level variation, and hydraulic role of fractures. It also showed the influence of the depth of the drilling on productivity. These results contribute to the knowledge of the structure and hydrodynamic functioning of the aquifers of the basin basement. They show the structural links between hydrodynamics and aquifer productivity.","PeriodicalId":483196,"journal":{"name":"European journal of environment and earth sciences","volume":"33 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135366384","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 research aims to analyze the suitability of water quality in the ex-sand mining area for freshwater fish cultivation. Observations in three water ponds in Bantarwaru Village, Gantar District, in August 2022. Water quality measurements in situ and the laboratory. Water quality parameters observed in situ measured temperature, water depth, brightness, dissolved oxygen (DO), and pH. Laboratory measurements included TSS, TDS, BOD, COD, and chemical elements such as total phosphate, nitrate, nitrite, ammonia, sulfate, and iron. The data obtained were analyzed descriptively by making comparisons with the standard water quality based on standards of Government Regulation Number 22 of 2021 concerning Management of Water Quality and Control of Water Pollution. To find out how suitable the suitability for freshwater fish farming is. Suitability analysis using the weighting and scoring method. The scoring results for ex-sand mining ponds for freshwater fish farming are 81–91% and classified as moderately to highly suitable. This score is good for freshwater fish cultivation.","PeriodicalId":483196,"journal":{"name":"European journal of environment and earth sciences","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135482172","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 aims to explore the mapping of soil moisture in Bangladesh using multispectral remote-sensing satellite images. The purpose of this study is to prepare a map of soil moisture aiming to help government authorities in developing agricultural activities to accelerate the sustainable development of the rural economy in Bangladesh. A total of 14 Landsat scenes of paths 135-139 and rows 42-46 covers the entire Bangladesh. Thus, a set of Landsat imagery (a total of 14 scenes) for the year 2022 was used in this study to map the soil moisture of Bangladesh through the application of Geographical Information System (GIS) and Remote Sensing. Satellite Image preprocessing, correction, and analysis were done with ENVI software (version 5.1, developed by Research Systems, Inc., USA) and the ArcGIS software (version 10.6, developed by Environmental Systems Research Institute, USA). For the study of the long-term variation of soil moisture over Bangladesh and its seasonal characteristics, a soil moisture map can be used. In addition, to improve the climate model over Bangladesh, an up-to-date soil moisture map will be very helpful. The objective of this study is to provide accurate and detailed up-to-date spatial soil moisture information at reduced cost and time which is essential for environment modeling, risk assessment, decision-making for different government agencies and development partners, and help toward socio-economic development. In this study, the map shows soil moisture as very wet, wet, dry, and very dry soils of Bangladesh. The overall land cover classification accuracy was 92.56%, with a Kappa value 0.90 for Random Forest and the overall soil classification accuracy was 87.27%, with a Kappa value 0.858 for maximum likelihood classification indicating good consistency.","PeriodicalId":483196,"journal":{"name":"European journal of environment and earth sciences","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134947662","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 reference to the 2023 World Climate Declaration, we document that exhaled CO2 drastically promotes the growth of a representative land pant. Using regenerated cuttings of Tradescantia geniculata, raised in moist soil, we show that, within 21 days of growth in a day-/night-cycle, CO2-enrichment (ca. 4 vol. % vs. 0.04 vol. % in the control) exerts the following effects: Average stem length is doubled, a three-fold enhancement in the number of branches occurs, and adventitious roots, plus flowers, develop. This CO2-fertilisation-experiment is discussed in the light of the “Global Greening”-phenomenon, documented as large increase in plant biomass since ca. 1850. We also address negative effects of further rising CO2-levels in the atmosphere on the global environment in the ongoing Anthropocene. Finally, we point out that A. R. Wallace was not only a theorizing explorer of nature, but also an expert in animal- and plant physiology.","PeriodicalId":483196,"journal":{"name":"European journal of environment and earth sciences","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135739588","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}
