CHAPTER I INTRODUCTION WATERSHEDS A watershed is a basin-like landform defined by highpoints and ridgelines that descend into lower elevations and stream valleys. A watershed carries water "shed" from the land after rain falls and snow melts. Drop by drop‚ water is channeled into soils‚ groundwater‚ creeks‚ and streams‚ making its way to larger rivers and eventually the sea. Water is a universal solvent‚ affected by all that it comes in contact with: the land it traverses‚ and the soils through

Everything has two faces. Though the hydroelectric has a lot of advantages‚ for its low cost and low pollution‚ still it has some disadvantages. In some Asian countries‚ like Philippines and China‚ people can see the hydroelectric production clearly by year. There are some hydroelectric stations which are typical in these

The Ten Biggest Dams in Asia Human’s never ending need of water dates back from the start of our existence. In the earlier days our ancestors have always been relying on the naturally occurring dams found in nature. But with the rapid increase of population‚ these natural dams are now very insufficient in providing enough water to supply the peoples demand for water. With a problem comes a solution‚ our early ancestors needed to find a more efficient way of getting and storing water for their needs

As if the doctrine of necessity‚ which has provided the alibi for all military coups since the original one of Ayub Khan‚ was not enough‚ a new and much more sinister doctrine‚ that of indispensability‚ is being promoted. Its purpose is to justify the indefinite continuation of the present

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
