Revealing the status of groundwater contamination before it reaches a critical level is crucial to effective groundwater management. DRASTIC is a groundwater quality model representing; Depth to Water, Net Recharge, Aquifer Media, Soil Media, Topography, Impact of vadose Zones, and Hydraulic Conductivity. ABSTRACT The Douala Basin is a divergent basin along the West African coast which developed by rifting between Africa and South America during break-up of Gondwanaland. Groundwater management can be effectively conducted by using groundwater contamination map assessment. According to this study, the groundwater vulnerability maps provide important preliminary information which could greatly help in the protection of local water resources. It simulates hydrologic and transport processes, and provides a database framework and visualization capabilities for hydrochemical analysis. The D.I for the different inhabited quarters were; Bonamoussadi (BS) = 145, Bali (BA) = 138, Bonapriso (BP) = 140, Airport(AP) = 129, Ndogbong(ND) = 120, Bepanda(BE) = 130, Vallee Besengue (VB) = 134, New Bell (NB) = 125, Bonassama BM) = 128 and Rail(RA) = 167. 23 talking about this. The average depth to groundwater (D) ranges from 9.98 to 22.22 m and were assign ratings 3 (for shallow wells) and 5 (for deeper wells).

While field measurements demonstrated high levels of groundwater salinity depending on the density of urbanization, both vulnerability assessment methods exhibited a limited ability in capturing saltwater intrusion dynamics. The non-point source pollution was effectively determined by the modified DRASTIC method compared with the traditional method. Groundwater vulnerability is defined as the tendency of contaminants to reach a specified position in the groundwater system after introduction at some location above the uppermost aquifer (Worrall and Besien, 2005, Rahman, 2008, Bai et al., 2011). Founded in 1986, the Nico Halle & Co.

The coastal basins are the Douala/Kribi-Campo and the Rio Del Rey Basins. Maud. Whilst the country relies mainly on desalination of seawater to secure water supply, groundwater has extensively been used for irrigation over the last three decades, which caused adverse environmental impact. These are passive margin basins formed in the Cenozoic following the opening of the South Atlantic Ocean when the Gondwana supercontinent broke up in the Late Jurassic. Cabin crew certificate course. In Cameroon, as in most developing African countries, people in urban and peri-urban areas do not have easy access to pipe-borne water. Though the current levels of contamination are within permissible limits, the risk of further contamination cannot be ruled out, and is indeed rather likely. This provides further evidence that the period 2.1–2.2 Ga was one of the important stages of Birimian magmatism that led to the generation of the granitoids. This rifting resulted in the formation of a break-up unconformity near the beginning of Albian time. Therefore, carrying out studies on the pollution potentials of the aquiferous formations in Douala will serve as a blueprint to the sustainable management of this natural resource. (2015) (120 < VI < 199) in the city of Douala in Cameroon, Edet (2014) in Calabar, Nigeria (124 < VI < 170) which are all located in sedimentary environments.However, they are of the same order of magnitude as those obtained by Al-Adamat et al. Moderate vulnerability zone was observed around P102, P310, P311, F401, P402, P403, P404, P501, P506 and P503, identified in the Mfomchout, Ngâ and Lompit basins.These vulnerability indices are slightly lower than those obtained by Feumba (2015) (115 VI<164) and Akenji et al. The estuary lies to the east of Mount Cameroon and empties into the Bight of Biafra.It is fed by the Mungo, Wouri and Dibamba rivers. ... follow up on Agenda 21 a commission on Sustainable Development was created within the Excellente formation très complète et réalisée par une experte qui ne cesse de mettre à jour ses connaissances pour nous les transmettre.

A positive correlation was observed between groundwater vulnerability and concentration of nitrate in groundwater. Groupe Eclipse, c’est petit mais irrésistible ! Services Douala. -make up-pose des cils et extensions. Basically, with the adopted statistical technique-Correspondence Analysis-one identified and minimized redundancy between DRASTIC features, allowing for the calculation of a composite index based on just three of them: topography, recharge and aquifer material. Ricin, Amla, Coco, Moutarde, Brocoli, Avocat, Jojoba, Olive : ce produit réunit 8 huiles végétales BIO précieuses pour des cheveux brillants, souples et forts. The vulnerability assessment method presented in this study is based on two approaches: DRASTIC and EPIK, within the framework of Geographical Information System (GIS). Une étude de marché réalisée dans la ville de Douala va leur permettre d’identifier les maux du marché de la cosmétique en général et du make-up en particulier.

The main objective of this work is to study shallow aquifers in the Foumban locality by applying the DRASTIC and GOD models coupled with the Multivariate Statistical Analysis in order to efficiently assess the vulnerability of these aquifers. In any given area, the groundwater within an aquifer, or the groundwater produced by a well, has some vulnerability to contamination from human activities (Rahman, 2008). Opportunité de collaboration: Vous êtes passionné de mode? The aim of this study is to develop a new fuzzy optimization model to find the optimal factor weights of modified DRASTIC index for groundwater vulnerability mapping an urban aquifer to nitrate contamination. A positive correlation was also noticed, while validating the final DRASTIC map, between the vulnerability classes and the three groundwater quality parameters-electrical conductivity, nitrate and chromium concentrations. The study area is located around the town of Küplüce between the Çelikhan and Sincik districts (Adıyaman, Turkey). Based on the DRASTIC model, the result showed that the study area is weak and moderately vulnerable. From data, five thematic maps were generated and an intrinsic vulnerability map was developed based upon calculations of DRASTIC Indices (D.I). The proof resulted from a validation of DRASTIC and vector-DRASTIC by the results of a groundwater pollution risk assessment standing on the spatial distribution of land uses and nitrate concentrations in groundwater, referred to as [NO3-]-DRASTIC method. 24 heurs; 3 jours; 7 jours; 30 jours; Tranche de prix-OK.

It was determined that mineralisation deposits were vein-type hydrothermal deposits that had developed due to Middle Eocene acidic-intermediate intrusions intersecting Palaeozoic-aged Pütürge metamorphics, and that they exhibited similar characteristics to other mineralisation deposits observed along the Southeastern Anatolian Orogenic Belt. Bold Make Up est une marque de maquillage pour peaux ethniques 100% … 166-179, Journal of African Earth Sciences, Volume 102, 2015, pp. The pollution potentials of aquiferous formations is obtained by evaluating the aquifer vulnerability. Integrating advanced simulation techniques and data analysis tools in a freeware Geographic Information System (GIS) provides a valuable contribution to the management of conjunctive use of groundwater (the world's largest freshwater resource) and surface-water. The best result was obtained by using AHP–AHP, followed by DRASTIC–AHP, modified DRASTIC–AHP, and AHP–DRASTIC models. An assessment of aquifer intrinsic vulnerability was conducted in the Sordo river basin, a small watershed located in the Northeast of Portugal that drains to a lake used as public resource of drinking water.
