The flexibility of the aquifer to transmit water in financial portions in wells rely on the aquifer features which involve Hydraulic conductivities(K), Transmissivity(T) and Storativity(S). All have been identified making use of Jacobs straight line approach. Aquifer features gives facts to determine the assorted h2o making units for groundwater prospecting and management with the aquifer technique. The intention of this review is to ascertain the aquifer attributes in parts of Lere, Kaduna in North western Nigeria. Pump exam knowledge of twenty five boreholes in the review space had been made use of to find out the aquifer features of the area.
The purpose of the analyze was to ascertain the aquifer parameters in Erho, Nigeria. This was completed by drilling three test wells and a few observation wells within the analyze locale. Drinking water was pumped from your test wells at a relentless fee when the drawdown within the observation wells was firm as being a operate of your time. The info attained have been subjected to graphical and analytical analysis utilizing the Cooper-Jacob method.
A mixed classification of magnitude and variation of transmissivity is proposed, with the intention to standardize the expression, comparison, and illustration of transmissivity. This classification also permits its compact and unambiguous depiction in tables and maps.
final results present which the aquifers on the research spots are of average to low or restricted generate. The
Paul's as well as Romanche oceanic rework faults. Some twenty m.y. of completely transform fault movement may have elapsed before West Africa was totally divided by oceanic crust from northern Brazil. The South Atlantic, Benue trough, as well as Gulf of Guinea shaped an unstable RRF triple junction, which may have prompted inner pressure within the African plate. It might also have resulted in achievable dilation with the Gulf of Guinea change faults which, together with the small intervening ridge segments, served to localize the Cretaceous volcanicity considered answerable for the just lately found North Brazilian Ridge.
Geoelectric survey utilizing Vertical Electrical Sounding (VES) was carried out in parts of Ikot Abasi Area Govt Region, Akwa Ibom state, Nigeria. Within this area there's no borehole which has been Akpen state Benue drilled right until now, the most crucial targets of this analyze will be to certainly be a guide for your suited placement of borehole so as to stay clear of wild cat drilling and likewise to stay away from salt intrusions utilizing the VES ... [Show full summary] geophysical techniques. Schlumberger electrode configuration was used in getting the info. 4 to 5 geoelectric levels were being delineated from the interpreted results.
Estimates of aquifer transmissivity from specific potential details of water wells from seventy (70) destinations
Day by day rainfall data of 31 yrs was utilized for the examine. The day by day rainfall facts was subjected to several analyses. The end result attained indicated that there's a downward development while in the rainfall volume gained in Abuja throughout the last 31 years. Also, a gradual decadal decrease in rainfall was noticed using the SPI to compare the 3 decades under evaluate.
NIJOTECH allows open up entry for distribution in the posted article content in any media so long as full (not aspect) of content are dispersed.
The capacities of the water‐bearing development to transmit h2o underneath a hydraulic gradient and to produce water from storage when the water desk or artesian pressure declines, are typically expressed, respectively, concerning a coefficient of transmissibility as well as a coefficient of storage.
Evaluation outcome exhibits that the check is significance with p-price of 0.006 and coefficient of resolve-R2 price of 0.581. The product created was utilized to make predictions for your period of six yrs forward; which demonstrates continuous rise in the pattern of rainfall determined by the obtainable info. The irregularity while in the sample of rainfall requires significant motivation in becoming a member of the force for climate change abatement procedure.

Transmissivity is often approximated from specific capacity details due to expense of conducting typical aquifer checks to acquire transmissivity plus the relative availability of distinct potential knowledge.
