"Sphere of Influence" in Geological Engineering The sphere of influence that geography exerts over almost all human activity cannot be understated. The physical geography of a land has a vast influence on the activities in that country, and this is to a large extent also dependent on the geological formations that are part of the environment.
Basics of Environmental Engineering Environmental engineering began as sanitary engineering when the importance of drinking water treatment and waste water treatment were first realized. Later it was converted to environmental engineering, including air pollution and water pollution control and solid and hazardous waste management.
Design Parameters of Foundations in Seismic Zones In seismic zones foundations are subjected to additional forces due to earthquakes. This will depend on the area and intensity of the earthquake. Design should take into consideration these forces.
Topography of the Ocean Floor The study of the ocean floor topography is interesting since it offers details of a vast area comprised of hills, mountains, and valleys, all covered with water. The ocean floor topography starts with the Outer Continental Shelf followed by the Continental Slopes, and subsequently the Ocean Floor.
Erosion Control Using Geosynthetics Erosion of soil may take place due to wind, rain, and flowing water. If erosion is not properly controlled, it may create serious problems. There are different methods for preventing erosion, but the most effective method is the use of geosynthetic mats for erosion control.
Rock Mechanics Defined It is necessary to understand what is rock mechanics if you are to take advantage of the properties of rocks and understand how they will function during the various uses that engineers put them to.
Environmental Engineering Defined Environmental engineering deals with air pollution control, hazardous waste management, wastewater treatment, and water treatment. Environmental engineering work includes planning, design, construction, and operation of equipment, systems, and structures for the protection of the environment.
Cliff Stabilization Cliff stabilization becomes a must especially in areas that are developed. It is required in all moderately or severely exposed coasts to preserve the landscape. It is the natural behavior of cliffs to slide due to weather and other action and thus require stabilization.
Drill-in Fluids for Wellbores In geotechnical engineering there are numerous types of drill-in fluids for wellbores. The most popular are water or oil-based mud, and gaseous drilling fluids. They are used among other things to prevent the ingress of surrounding formation fluids into the well bore and to keep the drill bit cool.
