Current Journal of Applied Science and Technology, Page 1-8
DOI: 10.9734/BJAST/2016/30185

The present research was implemented to analyses the seedling tolerance of three species Eucalyptus gomphocephala DC (Myrtaceae) (common name 'Tuart'), Eucalyptus marginata Sm. (common name 'Jarrah') and Corymbia calophylla (Lindl.) K.D. Hill & J. A. S. Johnson (common name 'Marri') to soil-induced stressor, namely soil alkalinity (limestone). Seeds germinated in shallow trays filled with white sand in a naturally lit glasshouse (control treatment). A liming treatment was conducted with 20% w/w crushed and sifted Tomala limestone adds to potting mix to increase soil pH. The experiment was conducted over 82 days. E. gomphocephala is restricted soils overlying limestone on study area and according to total seedling dry weight data and calculated relative growth rates coped best in a limestone-enriched soil. However, when examining all the growth and physiological data collected C. calophylla appeared to be the middling tolerant, with no significant difference in leaf allocation or leaf water loss between the well-watered controls and the limestone-enriched treatments whereas the E. marginata was the least tolerant with a 14% reduction in stomatal conductance.

Consolidation is the reduction of soil volume with time. This phenomenon generates a stresses transfer process beginning with the application of load and subsequent increase in pore water pressure. This increase in pore water pressure generates a flow of water that reduces the volume of soil. Thus, consolidation represents a hydro-mechanical coupled problem. Different models have been developed to simulate this phenomenon properly. This paper presents a coupled hydro-mechanical consolidation model for saturated materials. It can also be extended to the case of unsaturated materials when effective stresses are used. This model considers different drainage, displacement and loading conditions. It properly simulates the phenomenon of consolidation and is consistent with other models. It also correctly reproduces laboratory tests.

DOI: 10.9734/BJAST/2016/29608

Hydrogeological studies and groundwater flow of Emure Ile located in the crystalline basement area of Emure, near Owo, Southwestern Nigeria, has been done. The local geology of the area is predominantly granite-gneiss and migmatite. Hydrogeological measurements were determined from twenty eight existing non-flowing wells across the area. The measurements were used to compute the thickness of the water column/vadose zone, static water level, and hydraulic head of the wells across the area. The hydraulic head measurements were used to develop the groundwater flow model for the area. A total of twenty depth sounding data were acquired using Schlumberger array and presented as sounding curves. The groundwater flow model map shows that groundwater flow is towards the west – east direction representing the central part of the town. The thickness of the water columns/vadose water (average of 2.6 m) and total depth of the wells (average of 5.4 m) are generally low and shallow. The depth to groundwater (water table) ranges from 2.6 m to 4.7 m, with a modal range of 1 – 3 m suggesting a thin vadose zone. Based on DRASTIC index rating, the vadose zone thickness generally fall within high vulnerability rating, aptly suggesting that the aquifer in the area is significantly vulnerable to contaminants deriving from anthropogenic sources. This result corroborates the deduction from the overburden protective map. The interpreted sounding curves revealed three distinct geoelectric layers overlying the resistive basement, the topsoil, the weathered layer and the partially weathered/fractured basement. The unconfined weathered layer is the main aquifer unit in the area, with resistivity ranging from 7 to 101 Ohm-m suggestive of sandy-clay; and thickness ranging from 2.0 to 84.9 but generally less than 20 m. Therefore combining all the results, the best groundwater development areas with less vulnerability to contamination are found in northwest - southwest parts which constitute for about 30% of the area. However, the groundwater potential of the area is generally low.

Triangular ditch irrigation may be used to raise the downstream water surface. In this paper hydraulic jump in a sloped triangular channel of 90° central angle has been studied and analyzed using field experiments. The paper aims to determine the effect of the triangular channel’s bed slope on the hydraulic jump characteristics such as sequent depth ratio, relative jump height, relative energy loss, and the relative jump length. For this motive, wide range of bed slopes, nine positive slopes were tested. The obtained results were represented in dimensionless curves and empirical models using Buckingham’s π-Theorem. The developed curves and empirical computational models were used to estimate the different hydraulic jump characteristics for different initial Froude number and triangular channel bed slope. Also, the obtained results were compared with the pervious results of horizontal triangular channel layout.

Landsat 7 ETM Satellite imagery for 1987 and 2013 were used in a geographic information system to map and model changes in the Landuse and Landcover along the freshwater Riparian corridor of the New Calabar River. Percentage change in six Landuse-Landcover (LULC) features, namely Freshwater forest, Grassland, Barren-Sparse Vegetation, Scrub-Shrub, Agriculture and Urban/Builtup, were calculated from the differences between the pixels of the LULC in the imagery for 1987 and 2013. The pattern of changes along the buffer zones between 50 m and 500 m was a mixture of gains and losses in the LULC types. The freshwater forest declined between 0.6%-22%. In the Barren/Sparse vegetation category, there was a decline of between 9-16% but an increase of 323% was experienced at the 50 m buffer. The gains and losses were observed for the Grass category with 2-30% losses and 233% gain at the 50 meter buffer. Similar observations in the Scrub-Shrub category showed that losses were between 1.3-1.6% while a gain of 11% was observed at the 50 meter buffer. The Agriculture and Urban-Builtup maintained a significant increase across the buffer zones with values of 24-160% and 24-358% respectively. A grid based Riparian reach alteration zone modeling showed that high and extreme changes in LULC occurred mostly at the middle and lower reaches for Urban/Builtup (45%); Scrub-Shrub (34%); Barren/Sparse (40%). High and Extreme values in LULC extending to the Upper reaches were observed in Grass category (51%); Freshwater forest (40%) and Agriculture (55%). The cumulative composite model identified 33% of the grids with high and extreme value change coefficients in the middle and lower reaches. Grids of Moderate hotspots of change comprising 33% occurred at upper and lower reach zones of the Riparian study area. In all the chi-square statistics provide strong evidence of the differences (p =0.0382) that accounted for the composite variation within the Riparian reaches. It also provided evidence for the differences (p<0.0001) in the proportion of pixels that accounted for Gain and Loss of the different LULC types within riparian buffer zone in this study. The study provides information for targeting management objectives towards Riparian ecosystem resiliency for this section of the New Calabar River.
