One of the best places for building a dam is a narrow part of a deep river valley; the valley sides can then act as natural walls. The primary function of the dam’s structure is to fill the gap in the natural reservoir line left by the stream channel. The sites are usually those where […]
The common purposes for the construction of dams are as follows:
Dams can be formed by human agency, natural causes or even by the intervention of wildlife such as beavers. Man-made dams are typically classified according to their size or height and intended purpose or structure. 31.6.1 By size International standards define large dams as higher than 15–20 m and major dams as over 150–250 m […]
Early dam building took place in Mesopotamia and the Middle East. Dams were used to control the water level, for Mesopotamia’s weather affected the Tigris and Euphrates rivers, and could be quite unpredictable. The earliest known dam is situated in Jawa, Jordan, 100 km northeast of the capital Amman. The Ancient Egyptian Sadd Al-Kafara at […]
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, levees and dikes are used to manage or prevent water flow into specific land regions.
Irrigation has the following main classes: Flow Irrigation: Flow irrigation is that type of irrigation in which the supply of irrigation water available is at such a level that it is conveyed onto the land by gravity flow. Flow irrigation may be further divided into perennial irrigation system and inundation or flood irrigation system. In […]
Apart from increase in the production of food, there are many indirect benefits or advantages of irrigations such as:
Irrigation is defined as the process of artificial supply of water to soil for raising crops. It is a science of planning and designing an efficient, low-cost, economic irrigation system tailored to fit natural conditions. It is the engineering of controlling and harnessing the various natural sources of water, by constructing dams and reservoirs, canals […]
Municipal engineering is concerned with municipal infrastructure. This involves specifying, designing, constructing and maintaining streets, sidewalks, water supply networks, sewers, street lighting, municipal solid waste management and disposal, storage depots for various bulk materials used for maintenance and public works, such as salt and sand, public parks and bicycle paths. In the case of underground […]
Traffic engineering is a branch of civil engineering that uses engineering techniques to achieve the safe and efficient movement of people and goods. It focusses mainly on research and construction of the immobile infrastructure necessary for this movement, such as roads, railway tracks, bridges, traffic signs and traffic lights. Increasingly, however, instead of building additional […]
