Reporting a Case on the Risk Assessment for Karst Hazards at a Facility in Saudi Arabia

This paper gave a practical example of the challenges facing an existing facility built on a karstic limestone formation in 1970’s. Multiple geophysical techniques such as Microgravity, Electrical Resistivity Imaging, Vertical Seismic Velocity Profiling, Cross Hole Seismic Tomography, Ground Penetration Radar, Multi-Channel Analysis of Surface Waves, as well as boreholes and down-hole video imagery, were

Piping roles as the main bridge between membrane modules and relevant pumps in membrane water treatment plants. The pipes deliver only water, both water and air, only air or chemicals (alkaline or acid detergents) from the pumps to the membranes, depending on the operation modes of the membrane. Various fluid phenomena occur in the same

India witnessed self-sufficiency in food production due to the grand success of Green revolution introduced in 1960’s by the advent of the 20th century, the soil health was completely lost due to the rampant use of the agrochemicals. Instead of undertaking a new anthropogenic venture to deal with the problem, it was suggested that the

Quantification of the above ground carbon stock (AGC) is important in sustainable forest management and policy advice on climate change mitigation. Remote sensing when combined with few ground collected data has the potential of improving forest resource assessment even though this opportunity has not well been utilised. In this study, we mapped AGC through combination

The objectives of this study were to describe the distribution of macrophyte assemblages in relation to physico‐chemical parameters of their environment and to assess the variability in ecological metrics throughout the Walloon river network. Two-way clustering allowed us to simultaneously assign sample units and species to groups by performing two separate cluster analyses. Indicator species

The carbon (C) stored in the living biomass of trees is typically the largest C pool of the forest ecosystem which is directly impacted by deforestation and degradation. With the global efforts to combat climate change through afore-station and reforestation to reduce carbon emissions in the atmosphere, natural forests conservation and tree planting programmes are

Bottom hole temperatures (BHTs) and static formation temperatures (DSTs) of 70 deep exploratory wells are used to evaluate the geothermal regime in the northeastern part of Sirt Basin. The structural and stratigraphic evolution of the Sirt Basin was developed during four main tectonic phases corresponding to plate reorganization, which is tied to the evolution of

This research presents damage causes of the pylons in the ancient Egyptian temples based on 3D finite elements analysis. The main purpose of the research determines the failure causes of the first pylon of the Ramessium temple, which is situated in Upper Egypt, at Luxor “Thebes” on the west bank of the Nile River. The

This paper presents a three dimensional geological reservoir model created using stochastic simulation. The oil field presented is an East African oil field formed by a structural trap. Data analysis and transformations were conducted on the properties before simulation. The variogram was used to measure the spatial correlation of cell based facies modeling, and porosity

In Ethiopia, climate change is set to hit the agricultural sector adversely and cause considerable negative impacts particularly for smallholder farmers. Weather information is one of the requirements for effective climate change adaptation in Ethiopia, where Agriculture is the backbone of the economy. This study made during 2011/12 investigates whether smallholder farmers, development agents and
