Seasonal Ground water Configuration Maps showing Water level in Kano Metropolis, Nigeria.

Abstract: 

The paper presents the peak of dry and rainy season’s ground water configuration maps, so as to show the seasonal water level fluctuations in the study area. It involves measurement of wells elevations, static water levels from hand dugged wells at peaks of dry and rainy seasons and their elevations. The groundwater levels at peak of dry season in the area during the course of the study range from 3.20 to 19.00 mbgl (meter below ground level) with an average of 8.09mbgl. The maximum water levels elevation during the dry season was 500 masl (meter above sea level), minimum of 425.6 masl and average of 467.38 masl. While the water level measurement at peak of rainy season range from 0.50 to 12.0 mbgl. The maximum water level elevation was 508 masl, minimum of 444.60 masl and average of 479.04 masl. The differences in the groundwater levels for both peaks of dry and rainy seasons could be related to the variations in elevation, quantity of recharge, hydraulic properties, and other hydrogeologic conditions of the superficial aquifers in the study area. Information on the depth to water level has various uses, such as in borehole drilling, geotechnical investigations (for dams, roads, buildings etc), and in determining the direction of groundwater flow, which can be used for monitoring and identifying possible groundwater contamination

LINEAMENT ANALYSIS FOR ANKA SHEET 52, NE ZAMFARA STATE, NORTH WESTERN NIGERIA

Abstract: 

Remote sensing data (DEM) was used to study and analyze lineaments within Anka sheet 52 NE. Eight Shaded relief images were created by varying the solar Azimuth (0°, 45°, 90°, 135°, 180°, 2250, 2700, 3150). A solar elevation of 30o and an ambient light setting of 0.2 was chosen to ensure good contrast. Combination of shaded relief images 0°, 45°, 90°,135° and 180°, 225°, 270°, 315°was done to produce two combine shaded relief images. Automatic extraction of lineaments from these combine shaded relief images was carried out followed by buffering of lineaments to ensure continuity. Buffering of lineaments was followed by reclassification and combination of two reclassified image to generate a level of coincidence image. Reclassification of level of coincidence image was carried out followed by manual digitization of lineaments. Analysing these lineaments, it was observed that lineaments generated from combination of shaded relief images (0°,45°,90°,135°), had a dominant NW-SE direction. 52 lineaments were extracted from these images having a maximum length of 13701.2 m, minimum length off 2293 m. Lineaments extracted from combine shaded relief image (180°,225°,270°,315°) had a dominant N-S direction. A total of 47 lineaments were extracted and lineaments have a maximum length of 4346.093 m, and a minimum length of 2324.74 m. 90 lineaments were digitized from the final lineament map. A maximum length 8300.71m, a minimum length of 993.451 was recorded. A dominant N-S and NW-SE dominant directions was observed to be the dominant directions from the final lineament map. From this study it was observed that most streams within the study area are controlled by the lineaments. Also, the dominant N-S and NW-SE directions for lineaments can be related to Pan African orogeny.

Assessment of Naturally occurring Radioactive Materials (Norm) Along Jakara Waste Water Canal, Kano, Kano State, Nigeria

Abstract: 

This study is an assessment of the radioactivity level along the Jakara waste water canal. Five soil samples from different points along the canal were analysed using the Gamma Spectrometry with Sodium Iodide detector (Model Name: Canberra, Model Number: 727, Serial Number: 11914167). The results obtained for the Naturally Occurring Radioactive Materials (NORM) show that the activity concentration for 40K ranges from 242.61 Bq/Kg to 548.67 Bq/Kg and its calculated average value being 347.71 Bq/Kg. Values for 226Ra activity concentration ranges from 18.31 Bq/Kg to 38.58 Bq/Kg and having an average value of 24.47 Bq/Kg, while that of 232Th ranges from 34.77 Bq/Kg to 84.95 Bq/Kg with an average value of 47.85 Bq/Kg. Hence, this NORM result reveals that the activity concentration of 40K and 232Th near the abattoir, as well as 226Ra near Jakara police station are all higher than the world wide average. The calculated absorbed dose rate, ranging from77.23 nGyh-1 to 141 nGyh-1, at all the sample locations as well as the gamma index at the abattoir were found to be higher than the acceptable limit for the general public whereas the calculated annual effective dose equivalent, radium equivalent activity, the external and internal hazard indices, and also the alpha indices at all the sample sites plus the gamma indices at the rest locations apart from the abattoir, are all found to be lower in values than the specified limit.

An Assessment on Concentration Level of Heavy Metals in Some Selected Soils of Sule –Tankarkar Local Government Area of Jigawa State North-Western Nigeria

Abstract: 

The work tries to assess the concentration of heavy metals in soil of Sule-Tankarkar Local Government Area of which ten sample sites were selected based on the reconnaissance survey to the study area. Atomic Absorption Spectrophotometer (ASS Buck Scientific VGP 210 Model) was used to analyze the soil samples collected from the depth of 0 to 20 cm each. The result revealed that the mean value for all the nutrients in the sampled soil sites are; Ca = 0.1350 meg/100g; Cd = 2.839 ppm; Co = 0.538 ppm; Cr = 0.62 ppm; Cu= 1.519 ppm; Fe = 0.518ppm; K = 0.0301meg/100g; Mg = 0.01meg/100g; Mn = 3.09ppm; Na = 0.0026 meg/100g; Ni = 2.86ppm; Pb = 0.473ppm; and Zn = 0.522ppm. This gives an indication that some of the elements fell within the ranged of permissible level in the soil as required by WHO (Ogundele et al., 2015), while others are either below or above the permissible limits. This provides an avenue for understanding the deficiencies and excesses of the elements in the soils for appropriate agricultural measures, high potential crop yield, uphold food security and land tenure problems.

CATCHMENT LOCATIONS OF BUYERS FOR AGRICULTURAL FOOD-PRODUCT WHOLESALE MARKETS IN KANO METROPOLIS, NIGERIA

Abstract: 

The study examined the catchment locations from where buyers patronized wholesale markets for agricultural food products of Kano Metropolis. Focus Group Discussion was used to collect data on catchment locations of buyers. The data were qualitatively analyzed through collation and arrangement of the FGD result. The catchment locations of the buyers were mapped out with the aid of ARCGIS software. Schedule Interview with buyers was used to establish the reasons for patronizing the markets. Descriptive statistics, particularly percentages, were used to analyze the data related to the reasons. The significant difference among buyers regarding reasons for purchase of products was determined with use of chi square. The study revealed differences in the catchments of the three markets both internally (within Nigeria) and externally (outside the country). Dawanau market had wider catchment; buyers came from far more distant places up to Libya in North Africa. Yankaba market had the least catchments, with buyers coming from Niger Republic. Internally, however, Yankaba market had wider catchment, with buyers coming from Middle-belt, Western and Eastern Nigeria. For Yanlemo, the patronage was more from the northern part of the country. The buyers patronized due proximity, cheapness, variety, availability and quality. Yankaba was the most diverse with all qualities featuring either alone or in a combination. Two-thirds patronized Dawanau due to cheapness/variety/quality. Cheapness/variety attracted two-thirds to Yanlemo market. The study recommended for further studies on boundary delineation, demographics, customer purchase data, competitor locations and temporal fluctuation of the catchment areas.
