The flexibility of the aquifer to transmit h2o in financial portions in wells rely upon the aquifer traits which include Hydraulic conductivities(K), Transmissivity(T) and Storativity(S). All were being identified employing Jacobs straight line approach. Aquifer properties provides info to detect the varied drinking water producing units for groundwater prospecting and administration of your aquifer program. The aim of the research is to determine the aquifer traits in elements of Lere, Kaduna in North western Nigeria. Pump take a look at info of 25 boreholes in the analyze place ended up utilized to ascertain the aquifer traits of the area.
The goal of the review was to ascertain the aquifer parameters in Erho, Nigeria. This was carried out by drilling 3 examination wells and three observation wells while in the examine spot. Water was pumped with the check wells at a continuing price whilst the drawdown in the observation wells was resolute being a operate of your time. The data acquired were subjected to graphical and analytical analysis using the Cooper-Jacob strategy.
On this analyze the yearly rainfall data of forty yrs (1978-2017) for South-South, Nigeria was gathered through the archive of NiMet. A few approaches ended up used for the Evaluation; statistical dissimilarities amongst two the equivalent-length time scales, coefficient of variability and the anomaly strategy. The pattern analysis working with t-check, Sen's estimator slope and Mann Kendall were also carried out so as to ascertain the pattern in the rainfall variables. The outcome show which the variances concerning The 2 suggests from the equal-size time scales unveiled variability of 7.00mm. In the same way, the CV of rainfall was 0.
The strategy Within this review was built over the track record that while there are numerous aspects that account for flooding, rainfall characteristic or designs continue to be the principal driver of flooding during the tropics. Thus, rainfall pattern Evaluation was carried out on the Makurdi drainage basin applying rainfall information from 1980 to 2014 to discover the flood bearing potentials from the rainfall. Investigation of variance (ANOVA), a few calendar year going mean, easy linear regression, rainfall anomaly index and Pearson Instant correlation were useful for the Examination. The regression line equation (y= three.414 + 1105), exhibits that Makurdi drainage basin has had boost in rainfall. The end result with the rainfall anomaly index exhibits that Makurdi drainage basin was characterised by bigger extent of incredibly soaked ailments in 1984, 1998 and 1999.
Paul's and also the Romanche oceanic completely transform faults. Some 20 m.y. of rework fault movement could possibly have elapsed in advance of West Africa was wholly divided by oceanic crust from northern Brazil. The South Atlantic, Benue trough, along with the Gulf of Guinea fashioned an unstable RRF triple junction, which may have induced interior strain from the African plate. It might also have resulted in feasible dilation from the Gulf of Guinea transform faults which, along with the limited intervening ridge segments, served to localize the Cretaceous volcanicity thought to be answerable for the lately identified North Brazilian Ridge.
Rainfall in Nigeria is extremely dynamic and variable on the temporal and spatial scale. This has taken a far more pronounced dimension as a consequence of weather transform. On this paper, Regular Precipitation Index (SPI) and Coefficient of Variability statistical equipment were being used to analyse rainfall traits and patterns in Abuja concerning 1986 and 2016.
Estimates of aquifer transmissivity from particular capacity details of water wells from seventy (70) destinations
Day-to-day rainfall data of 31 many years was useful for the research. The every day rainfall facts was subjected to many analyses. The end result acquired indicated that there is a downward trend inside the rainfall quantity gained in Abuja over the past 31 several years. Also, a gradual decadal decrease in rainfall was observed using the SPI to check the 3 many years beneath assessment.
NIJOTECH permits open up accessibility for distribution of your posted posts in almost any media so long as entire (not section) of articles or blog posts are dispersed.
Investigation result demonstrates the exam is importance with p-worth of 0.006 and coefficient of determination-R2 price of 0.581. The design developed was used to make predictions for any period of six many years ahead; which demonstrates continual increase in the pattern of rainfall based on the readily available data. The irregularity from the sample of rainfall requires severe determination in becoming a member of the drive for local weather transform abatement system.
AJOL is actually a Non Earnings Organisation that cannot purpose with out donations. AJOL as well as numerous African and Global scientists who depend on our free providers are deeply grateful for your contribution.
Write-up-construction Guidance (PCS) providers refer to all sorts of aid/aid offered to water company vendors (WSPs) to help them to detect, correct and keep h2o program infrastructure or stop potential procedure faults. PCS enhances the standard and sustainability of water offer services. This paper examines the provision of PCS to state h2o authorities in Nigeria. Especially, we discovered the sources of PCS and relevance of PCS; then we talked over the sample of event of technique faults the bureaucracy connected with PCS provision over the sampled states. Last but not least, we examined the constraints to PCS provision as well as selections for beating the difficulties. The research utilised empirical info derived from questionnaire surveys, by means of Akpen state Benue crucial informant interviews (KIIs) and from released literature. The information ended up analyzed utilizing descriptive statistical instruments.
316mm/calendar year for Makurdi, 1.268mm/12 months for Ilorin, 0.754mm/year for Enugu, 0.668mm/calendar year for Kaduna, one.873mm/year for Bauchi, 0.294mm/yr for Sokoto and 0.821mm/year for Maiduguri. Equally linear regression analysis and Mann-Kendall examination success show raising rainfall craze in all the studied spots besides in Port Harcourt that reveals a reducing trend. Nevertheless, rainfall traits ended up only statistically considerable in Benin, Ilorin, Bauchi and Maiduguri (at p < 0.05) at 95% self confidence level. This analyze reveals that Nigeria is going through an increase in rainfall. The implication of this is the fact that Nigeria is susceptible to the attendant effects of global warming. In this particular regard the human inhabitants in Nigeria depending on economic pursuits which have been rainfall sensitive including agriculture are liable to hazards. This analyze endorses the provision of exact and timely weather and local weather facts for preparing while in the sectors on the overall economy which can be rainfall delicate including agriculture,wellbeing, water assets management. This is able to protect against rainfall extremes from becoming disasters and threats to livelihood throughout Nigeria.
Most pumping tests are interpreted utilizing the classical Theis assumption of large-scale homogeneity with numerous corrections to account for early time conduct of drawdown curves. When drawdowns are plotted compared to log time, late time knowledge often delineate a straight line, and that is in step with Jacob's approximation of Theis' Answer but may well feel stunning in look at of the heterogeneity of pure media. The goal of our get the job done is to show that Jacob's approach results in a good approximation with the successful transmissivity of heterogeneous media when constrained to late time info. A review of numerous multiwell pumping checks demonstrates that when drawdown curves from Each and every observation very well are interpreted individually, they make very identical transmissivity T estimates.
