Teaching Geography Workshop 4: North Africa/Southwest Asia – Part 2: Egypt JIM BINKO: Our investigation of North Africa/Southwest Asia continues in Egypt. Here as throughout that region‚ the presence or absence of water has had a profound influence on human settlement. We will see the great impact that access to resources has on the characteristics‚ distribution and migration of human population on Earth’s surface. You will be able to understand how changes in the spatial distribution of

Most dams in active use today exhibit seepage of one form or another. The location‚ rate of flow‚ and turbidity (clear or murky) are the critical factors when evaluating the seriousness of seepage from a dam. Seepage is the continuous movement of water from the upstream face of the dam toward its downstream face‚ and is a major minor problem when it comes to the life span of dams and embankments. It is a major minor problem because if controlled the affects are minor and not hazardous‚ but if not

A dam is a barrier that impounds water or underground streams. Dams generally serve the primary purpose of retaining water‚ while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. Hydropower and pumped-storage hydroelectricity are often used in conjunction with dams to provide clean electricity for millions of consumers. It can also be used to collect water or for storage of water which can be evenly distributed

Aswan High Dam The Nile River runs through Egypt and Sudan. It has a lot of power that needed to be capture. To capture this power the Aswan Dam was built. This dam could not quite get the job done. Thus‚ the High Dam at Aswan was built. In a relatively rainless region‚ it is only because of the Nile River’s annual flood that the areas of Egypt and Nubia became habitable and airable. The flood would and could vary greatly

The Hoover Dam‚ a tremendous barrier holding up the powerful Colorado River‚ was built during the Great Depression. This project gave an average of 21‚000 people a job around the United States‚ hiring six companies. Construction on the Hoover Dam started April 20‚ 1931 and ended March 1‚ 1936; two years ahead of schedule. This was the world’s largest dam at the time; capable of holding 9 trillion gallons of water‚ weighing close to 6.6 million tons requiring 3‚250‚000 cubic yards of concrete as well

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
