Sand Dams in Kenya WHAT IS A SAND DAM? A Sand Dam is a steel reinforced concrete wall built across a sandy riverbed. During rainy seasons‚ a seasonal river forms and carries soil (consisting of sand and silt) which moves downstream. The heavy sand builds up behind the dam‚ whereas lighter sand and silt washes over the wall of the dam. Within the space of one to four rainy seasons‚ these dam types get completely filled with sand. However‚ approximately 40% of the volume held behind the dam is

ENGINEERING DISASTERS We can also call Engineering as in invisible science. No one can actually see how it works but it actually exists like an air. Example: Plain flies‚ building stands and many more. We don’t think how a building can stand weight without collapsing. Similar to apple’s company’s Moto ‘it just works. Here the main problems are not the designs but the material the use up building that design. The concept of total cost minimization is the roots of such accidents that just ruins lives

Local and migrating organisms affected by the dam: The creation of the Three Gorges Dam has lead to the endangerment and extinction of many plant and animals. The Three Gorges region is considered a biodiversity hotspot. It is home to over 6‚400 plant species‚ 3‚400 insect species‚ 300 fish species‚ and more than 500 terrestrial vertebrate species. The disruption of the river’s natural flow dynamics due to blockage will affect the migratory paths of fish. Due to the increase of ocean vessels in

Because they are "built-in" risks of management and control system due to agency problem and asymmetric information‚ managers often ignore them or are unaware of their existences. The purpose of this report is to provide insight of risk management and control system in the reality from the cases study

pH Readings: From the pH results recorded from the two water sources‚ we can clearly see that Kleinfontein Dam has the higher pH levels‚ which indicate poor and unsafe water conditions. From Article two‚ we can see that a High (7.5) or Low (5.5) pH level is very dangerous and harmful to humans who come in contact with the water. The pH Level recordings at 8 and 9 are extreme dangers if they were to come in to contact with humans and also they are way over the borders which is not acceptable at
