Abstract: Morphological features and Physico-Chemical Properties of twenty surface soils derived from five varied parent materials in Cross Rivers Sate, Nigeria were evaluated in relation to probable constraints to increase crop yields. Four replicate soil samples were collected from the top 15cm depth of each parent material for laboratory analyses using standard methods. Results showed that the colour notations, structure and texture of the soils were similar within Same Parent materials but varied widely across the locations. The particle size distribution showed that shale derived soils are finer in texture than those of other parent materials. Chemically, the soils are low in Plant........

Abstract: Organic matter occurrence in the soilcauses many problems for the engineering projects. In this study, seventeen locations have been chosen from Basrah soils with sampling frequency one sample per meter. For the experimental tests, Grain-size, Atterberg limits, and organic matter tests were performed on all the samples to evaluate the spatial distribution of the organic matter at selected areas in Basrah governorate. The results show that 62.3% of samples are classified as low plasticity clayey silt (CL), 27% as low plasticity silty clay (ML) and low plasticity organic soils ........

Abstract: The precipitation of atmospheric water vapour to the liquid or solid phase is accountable for clouds, rainfall and snow, which plays important role in climate and climate change. The energy released during vapor condensation affects the dynamics of the atmosphere. Through this interaction, the vertical stability of the atmosphere is modified, influencing the weather systems and their associated precipitation patterns. In this paper, we derived the total water vapour content in atmosphere using radiosonde observation over the Chennai radiosonde station (VOMM) for 44 years (1974-2017). The paper also highlights the statistical analysis of total water vapour content. The trend of total water vapour content in atmosphere is useful to understand the climate and its change in atmospheric conditions............

Abstract: This work was carried out to investigate the groundwater potentials of Lafia and environs using lineaments analysis. It studied the relationship between the characteristics and occurrence of groundwater in aquifers ranging from 50m-150m depth in the varying sedimentary rocks of the area by examining the possibility of groundwater occurrence in the different sedimentary rocks, despite the general understanding that shales are less porous and permeable. It shows the use of LANDSAT ETM+ imagery and geological map to investigate areas favourable for groundwater development........

Abstract: Natural hazards affect the progress towards sustainable development. Increasing effects ofnatural hazards viz. earthquakes, tsunamis, floods, landslides around the world has a directsocial, economic and environmental impact. The people living in the coastal areas of thetropics are exposed to various types of natural hazards of which the most devastating onesinclude high energy events such as earthquakes and tsunamis. The lithosphere of the Earth iscomposed of seven major and minor tectonic plates colliding, subducting or rifting apart withrespect to one another. This phenomenon has resulted in several tectonic plate boundariesaround the globe. The plate boundaries marked by subduction zones have produced numerousmega-earthquakes and associated transoceanic tsunamis. In the domain of the Indian sub-continent, the ongoing collision between the Indian plate and the Eurasian plate has resulted in the formation of......

Abstract: The electrical resistivity method is extremely useful to investigate the nature of subsurface formations by studying the variations in their electrical properties. This method assumed considerable importance in subsurface exploration because of very good resistivity contrasts among the lithological units, controlled depth of investigation, ease of field operations and low cost of instrumentation and operation. The Vertical Electrical Sounding (VES) method by Schlumberger electrode array applied in 77 Locations at Ongur River Sub Basin in Tamil Nadu, India. The Signal stacking Resistivity Meter Model SSR-MP-ATS was used to collect the VES data by employed a Schlumberger electrode configuration, with one side current electrode spacing (AB/2) ranging from 1 to 100 m and the potential electrode......
