Soil characterization, classification and evaluation offer helpful data with the comprehension of soil, its potentials and limitations for crop production. The review was to determine the morphological, Bodily and chemical properties of your soils; classify the soils; and Assess their suitability for maize, cassava and yam manufacturing. 3 land utilization styles (maize, cassava and yam) with a control plot Each and every had been useful for the analyze. A single soil profile pit was dug in Just about every land utilization kind and Handle. The pedons ended up described in-situ adhering to the strategies in FAO, s suggestions for soil profile description. A total of 23 samples ended up collected with the diagnostic soil horizons. The soils ended up categorized applying USDA Soil taxonomy and correlated with FAO/UNESCO Globe Resource Foundation.
In a terrific range of hydrologic issues, involving a perfectly or pumping district close to or in which drinking water‐levels are falling, the current concept is as a result not strictly relevant. This paper investigates partly the character and implications of the mathematical concept that considers the movement of ground‐drinking water in advance of equilibrium is arrived at and, as being a consequence, entails time as a variable.
Dedication of hydraulic properties of the aquifer capacity from pumping test: A scenario examine of Konshisha Location, central Nigeria
final results present which the aquifers of the study areas are of reasonable to reduced or limited yield. The
They noticed that Nigeria remains amongst a handful of nations throughout the world exactly where access to potable water is falling as opposed to mounting. ...
Nevertheless, the corresponding estimates for storativity span a broad assortment. This behavior is confirmed numerically for quite a few styles of development heterogeneity. An extremely important discovering of the numerical investigation is T values estimated working with simulated drawdown from particular person observation wells are all very close to the productive T benefit for parallel circulation. This was noticed even in nonmultiGaussian T fields, exactly where substantial T zones are very well related and in which the helpful T is larger in comparison to the geometric regular of point values. This implies that Jacob's approach can be employed for estimating efficient T values in many, if not most, formations.
Geoelectric study utilizing Vertical Electrical Sounding (VES) was performed in aspects of Ikot Abasi Nearby Federal government Area, Akwa Ibom Akpen state Benue state, Nigeria. Within this spot there is no borehole that has been drilled till now, the main aims of this research is to become a information for the ideal position of borehole as a way to avoid wild cat drilling and likewise to stop salt intrusions utilizing the VES ... [Demonstrate total abstract] geophysical tactics. Schlumberger electrode configuration was Employed in acquiring the data. Four to 5 geoelectric layers ended up delineated through the interpreted outcomes.
Determinations of both of these constants are almost always involved in quantitative scientific tests of ground‐drinking water issues.
Scrutinate proclivity of regional aquifer hydraulic parameters: apriorisms for borehole failures within aspects of the center Benue Trough, Nigeria

Background: Polyparasitism is popular in rural communities of the building globe, and it is a major problem for community overall health. The purpose of this research is to analyze the co-an infection of intestinal parasites and urinary schistosomiasis amid university-aged small children in two area government areas of Benue State. Procedures: This examine gathered 452 stool and urine samples from randomly picked contributors and examined them making use of three procedures - direct damp mount, formol ether focus, and urine sedimentation. The researchers also utilized questionnaires to assess danger aspects related to the samples. The data was then analyzed using the Chi-square statistical check to determine any considerable associations amongst the various variables examined. Outcomes: The study located that 29.0% with the 452 randomly selected individuals have been infected with at least just one parasite. 17.three% with the infected had been male, when 11.seven% have been woman.
Whenever a perfectly is pumped or or else discharged, water‐concentrations in its community are lowered. Unless of course this lowering happens instantaneously it represents a loss of storage, both with the un‐watering of the percentage of the Formerly saturated sediments When the aquifer is nonartesian or by release of stored h2o with the compaction in the aquifer due to the decreased strain if the aquifer is artesian. The mathematical idea of ground‐h2o hydraulics has long been primarily based, seemingly entirely, over a postulate that equilibrium has long been attained and thus that water‐stages are no more falling.
Right up until now no aim classification of transmissivity has become released, in spite of the quantitative nature of transmissivity values and their noticeable relevance for quantitative appraisals of aquifers or important floor-water techniques. The same old subjective expression of transmissivity, such as as “superior” or “low”, stops the objective comparison of transmissivity values characterizing distinctive spots and hydrogeological environments.
AJOL is on a yearly basis audited and was also independently assessed in 2019 by E&Y. Your donation is guaranteed to right add to Africans sharing their analysis output with a world readership.
Transmissivity is commonly believed from precise capability facts due to the expenditure of conducting regular aquifer tests to acquire transmissivity plus the relative availability of precise capability knowledge.
The analytic remedies predicting transmissivity from specific capacity tend not to agree well While using the calculated transmissivities, apparently on account of turbulent effectively reduction within the generation wells, which isn't taken under consideration by any in the analytic remedies. Empirical relations are better than the theoretical relations. Log‐log features have greater correlation coefficients than linear capabilities.
