Dedication of hydraulic characteristics of an aquifer capability from pumping check: A situation review of Konshisha Spot, central Nigeria
effects display the aquifers of your examine areas are of average to small or constrained yield. The
Paul's and also the Romanche oceanic completely transform faults. Some twenty m.y. of transform fault movement could have elapsed ahead of West Africa was completely divided by oceanic crust from northern Brazil. The South Atlantic, Benue trough, plus the Gulf of Guinea formed an unstable RRF triple junction, which can have triggered interior pressure during the African plate. It may well also have resulted in possible dilation of your Gulf of Guinea renovate faults which, along with the shorter intervening ridge segments, served to localize the Cretaceous volcanicity thought to be liable for the recently found North Brazilian Ridge.
Geoelectric survey utilizing Vertical Electrical Sounding (VES) was carried out in elements of Ikot Abasi Local Govt Space, Akwa Ibom state, Nigeria. On this area there isn't a borehole that has been drilled until now, the principle goals of this examine is to certainly be a guide for your suited posture of borehole so that you can keep away from wild cat drilling and also to stop salt intrusions utilizing the VES ... [Demonstrate entire summary] geophysical tactics. Schlumberger electrode configuration was Employed in getting the information. Four to 5 geoelectric levels have been delineated through the interpreted results.
Estimates of aquifer transmissivity from distinct potential information of h2o wells from seventy (70) destinations
Daily rainfall details of 31 decades was useful for the analyze. The day-to-day rainfall info was subjected to various analyses. The result received indicated that there is a downward pattern while in the rainfall amount of money obtained in Abuja throughout the last 31 yrs. Also, a gradual decadal drop in rainfall was noticed utilizing the SPI to match the 3 many years underneath overview.

History: Polyparasitism is prevalent in rural communities in the establishing environment, and It's really a major problem for public health. The intention of the examine is to investigate the co-infection of intestinal parasites and urinary schistosomiasis between faculty-aged small children in two local government parts of Benue State. Procedures: This analyze collected 452 stool and urine samples from randomly chosen members and examined them making use of three techniques - direct moist mount, formol ether concentration, and urine sedimentation. The scientists also utilized questionnaires to assess danger elements connected to the samples. The info was then analyzed utilizing the Chi-square statistical test to detect any major relationships concerning the different variables examined. Benefits: The examine uncovered that 29.0% from the 452 randomly selected contributors have been infected with a minimum of a single parasite. 17.three% of the infected were being male, though 11.7% had been female.
The issues regarding international warming/climate transform cannot be in excess of emphasized as it impacts almost each individual Portion of live. The sample of rainfall in Nigeria applying info on the standard rainfall for a period of eleven a long time was examined. The result showed a ongoing increase in the pattern of rainfall for any duration of 5 years inside the interval below analyze. Having said that the pattern was inconsistence with the remaining yr with some form of fluctuations. Sequence plot showed a transparent existence of development with the height period of time being the seventh year comparable to 2008 inside the period beneath examine.
static drinking water level and aquifer depth were being developed to point out these parameter variants inside the research place.
This review analyses Makurdi rainfall info from 1955 to 2015, for the purpose of Akpen state Benue detecting the rainfall variability, trends, and evaluating its implications on flood occurrence. Info on every day rainfall and flood occurrences ended up collected from relevant govt companies. Rainfall traits have been analyzed working with MannKendall, Spearmans rank correlation and Pupils t checks, each providing Virtually comparable success for that a few methods. Rainfall variability was analyzed using standardized precipitation index (SPI).
Provision of article building help (PCS) products and services to state water authorities in Nigeria: constraints and the way forward
Transmissivity is usually estimated from certain capacity details because of the expense of conducting typical aquifer checks to acquire transmissivity and the relative availability of specific capacity information.
Most pumping checks are interpreted using the classical Theis assumption of enormous-scale homogeneity with various corrections to account for early time conduct of drawdown curves. When drawdowns are plotted compared to log time, late time info usually delineate a straight line, which can be according to Jacob's approximation of Theis' solution but might seem to be shocking in look at from the heterogeneity of all-natural media. The purpose of our do the job is to point out that Jacob's approach brings about a superb approximation of the productive transmissivity of heterogeneous media when constrained to late time knowledge. A review of several multiwell pumping exams demonstrates that when drawdown curves from Each and every observation nicely are interpreted individually, they create extremely identical transmissivity T estimates.
