The power of an aquifer to transmit water in economic portions in wells depend on the aquifer traits which contain Hydraulic conductivities(K), Transmissivity(T) and Storativity(S). All were being decided applying Jacobs straight line strategy. Aquifer properties gives facts to recognize the various h2o creating models for groundwater prospecting and management in the aquifer technique. The purpose of the examine is to determine the aquifer characteristics in elements of Lere, Kaduna in North western Nigeria. Pump examination information of 25 boreholes throughout the review region had been made use of to determine the aquifer characteristics of the world.
The goal of this review was to ascertain the aquifer parameters in Erho, Nigeria. This was carried out by drilling 3 check wells and a few observation wells while in the analyze place. Water was pumped from your take a look at wells at a continuing amount although the drawdown during the observation wells was firm being a purpose of your time. The info obtained have been subjected to graphical and analytical analysis using the Cooper-Jacob system.
A combined classification of magnitude and variation of transmissivity is proposed, Together with the intention to standardize the expression, comparison, and illustration of transmissivity. This classification also enables its compact and unambiguous depiction in tables and maps.
They observed that Nigeria remains to be one among a handful of nations around the globe the place use of potable water is slipping rather then soaring. ...
Nevertheless, the corresponding estimates for storativity span a broad array. This behavior is verified numerically for numerous products of formation heterogeneity. An incredibly significant finding in the numerical investigation is the fact T values estimated making use of simulated drawdown from personal observation wells are all very close to the successful T price for parallel circulation. This was noticed even in nonmultiGaussian T fields, exactly where substantial T zones are well connected and exactly where the powerful T is bigger when compared to the geometric average of level values. This implies that Jacob's system can be used for estimating powerful T values in several, if not most, formations.
For articles which were developed from funded investigation, a transparent acknowledgement of this sort of assistance should be pointed out while in the post with related references.
Determinations of both of these constants are almost always linked to quantitative experiments of ground‐water troubles.
Scrutinate proclivity of regional aquifer hydraulic parameters: apriorisms for borehole failures within just aspects of the middle Benue Trough, Nigeria

Background: Polyparasitism is common in rural communities on the acquiring environment, and It is just a major problem for public wellbeing. The purpose of this research is to investigate the co-an infection of intestinal parasites and urinary schistosomiasis amid university-aged kids in two neighborhood Akpen state Benue governing administration areas of Benue State. Strategies: This analyze gathered 452 stool and urine samples from randomly picked members and examined them utilizing 3 strategies - immediate damp mount, formol ether focus, and urine sedimentation. The scientists also utilized questionnaires to evaluate threat elements related to the samples. The info was then analyzed utilizing the Chi-square statistical test to identify any substantial relationships concerning the varied elements examined. Final results: The examine discovered that 29.0% of your 452 randomly picked participants ended up contaminated with at the least 1 parasite. seventeen.3% on the contaminated were male, even though 11.7% were woman.
The problems about world warming/weather alter can't be over emphasised because it affects just about each individual A part of Reside. The pattern of rainfall in Nigeria employing info on the standard rainfall for your duration of eleven years was examined. The result showed a continuous boost in the pattern of rainfall for a duration of 5 years throughout the time period underneath study. On the other hand the pattern was inconsistence with the remaining 12 months with some kind of fluctuations. Sequence plot showed a clear presence of craze with the peak period of time remaining the seventh yr comparable to 2008 within the interval beneath examine.
An investigation of rainfall variability inside the upper and decreased river Niger basin improvement authority regions, Nigeria
This research analyses Makurdi rainfall info from 1955 to 2015, for the goal of detecting the rainfall variability, tendencies, and assessing its implications on flood occurrence. Data on daily rainfall and flood occurrences had been collected from applicable federal government agencies. Rainfall tendencies had been analyzed working with MannKendall, Spearmans rank correlation and Students t tests, both equally giving Virtually similar success for your 3 techniques. Rainfall variability was analyzed making use of standardized precipitation index (SPI).
Provision of submit design aid (PCS) companies to state water authorities in Nigeria: constraints and the best way forward
Transmissivity is frequently approximated from precise capacity info as a result of expense of conducting normal aquifer tests to obtain transmissivity and the relative availability of precise potential information.
Most pumping tests are interpreted using the classical Theis assumption of huge-scale homogeneity with a variety of corrections to account for early time behavior of drawdown curves. When drawdowns are plotted as opposed to log time, late time knowledge typically delineate a straight line, which can be in line with Jacob's approximation of Theis' Answer but may perhaps appear to be stunning in see of your heterogeneity of pure media. The purpose of our get the job done is to indicate that Jacob's approach leads to an excellent approximation of the successful transmissivity of heterogeneous media when constrained to late time knowledge. An evaluation of quite a few multiwell pumping exams demonstrates that when drawdown curves from each observation nicely are interpreted independently, they make extremely similar transmissivity T estimates.
