Soil characterization, classification and analysis give practical facts for the knowledge of soil, its potentials and restrictions for crop production. The study was to find out the morphological, Bodily and chemical Attributes in the soils; classify the soils; and Consider their suitability for maize, cassava and yam generation. A few land utilization varieties (maize, cassava and yam) by using a Regulate plot Just about every were utilized for the study. A person soil profile pit was dug in Every single land utilization form and control. The pedons ended up described in-situ pursuing the techniques in FAO, s suggestions for soil profile description. A complete of 23 samples were being collected through the diagnostic soil horizons. The soils have been classified applying USDA Soil taxonomy and correlated with FAO/UNESCO Planet Useful resource Base.

A mixed classification of magnitude and variation of transmissivity is proposed, With all the intention to standardize the expression, comparison, and illustration of transmissivity. This classification also enables its compact and unambiguous depiction in tables and maps.
The tactic Within this examine was produced on the history that nevertheless there are numerous variables that account for flooding, rainfall characteristic or patterns stay the first driver of flooding within the tropics. Thus, rainfall pattern Investigation was carried out over the Makurdi drainage basin making use of rainfall facts from 1980 to 2014 to establish the flood bearing potentials in the rainfall. Assessment of variance (ANOVA), 3 yr shifting imply, easy linear regression, rainfall anomaly index and Pearson Second correlation were useful for the Assessment. The regression line equation (y= three.414 + 1105), demonstrates that Makurdi drainage basin has experienced rise in rainfall. The end result from the rainfall anomaly index shows that Makurdi drainage basin was characterised by much larger extent of particularly damp problems in 1984, 1998 and 1999.
H2o borehole failures in Nigeria's Center Benue Trough are because of imprecise aquifer functions. This research employed empirical facts to grasp hydraulic parameters, foresee regional groundwater likely, and make clear borehole failures in hard geological locations. A total of 89 VES stations and quantitative facts interpretation ended up essential to find out the geoelectric Qualities beneath Just about every station. Aquifer layers ended up delineated and their resistivity and thickness were being mixed working with geo-setting distinct relations to produce transmissivity and hydraulic conductivity for each basement complex and sedimentary environments. Results clearly show that aquifer resistivity ranges from 4.
Geoelectric study utilizing Vertical Electrical Sounding (VES) was completed in elements of Ikot Abasi Nearby Federal government Region, Akwa Ibom state, Nigeria. During this area there is no borehole that has been drilled until eventually now, the leading objectives of the study is to be described as a information for the suited situation of borehole so as to keep away from wild cat drilling in addition to to avoid salt intrusions utilizing the VES ... [Exhibit comprehensive summary] geophysical tactics. Schlumberger electrode configuration was Employed in buying the data. Four to 5 geoelectric layers were being delineated from your interpreted benefits.
Determinations of both of these constants are almost always associated with quantitative reports of ground‐h2o troubles.
Daily rainfall data of 31 many years was used for the examine. The each day rainfall knowledge was subjected to several analyses. The result obtained indicated that there's a downward craze during the rainfall sum received in Abuja over the past 31 yrs. Also, a gradual decadal decline in rainfall was noticed using the SPI to check the 3 many years less than critique.

Assessment consequence exhibits that the test is importance with p-price of 0.006 and coefficient of resolve-R2 value of 0.581. The product developed was utilized to make predictions for the duration of six a long time in advance; which shows continual increase in the sample of rainfall based upon the accessible info. The irregularity in the pattern of rainfall calls for major dedication in signing up for the force for weather adjust abatement method.
static water degree and aquifer depth were made to show these parameter versions Akpen state Benue while in the examine place.
This examine analyses Makurdi rainfall information from 1955 to 2015, for the objective of detecting the rainfall variability, developments, and assessing its implications on flood prevalence. Facts on day by day rainfall and flood occurrences were being collected from related governing administration companies. Rainfall trends have been analyzed using MannKendall, Spearmans rank correlation and Students t exams, the two giving almost very similar outcomes with the 3 methods. Rainfall variability was analyzed working with standardized precipitation index (SPI).
AJOL is each year audited and was also independently assessed in 2019 by E&Y. Your donation is guaranteed to instantly lead to Africans sharing their study output with a world readership.
Within this examine, Now we have coupled floor geophysical system with pumping exam outcomes to supply a cost efficient and successful choice in aquifer parameter estimation. Vertical Electrical Sounding (VES) was carried out at forty web pages during the research area for the identification from the vertical variation in subsurface lithology and with the characterization of your aquifer system from the research area. The interpretation from the VES details exposed 3 to 5 geoelectric models Along with the depth to aquifer various from seven to 108m and the resistivity from the saturated layer various between forty two.
The analytic alternatives predicting transmissivity from particular capacity usually do not concur effectively Together with the measured transmissivities, apparently as a result of turbulent effectively reduction within the creation wells, which isn't taken into consideration by any with the analytic solutions. Empirical relations are a lot better than the theoretical relations. Log‐log capabilities have larger correlation coefficients than linear capabilities.
