Example text

The science of soil mechanics, and the understanding and measurement of critical soil characteristics. 5. Geological applications to dam engineering have improved enormously, especially the exploration of foundation conditions and the development of techniques dealing with adverse effects on dam stability, such as grouting, drainage, and seepage control. 6. Development of the concepts of probable maximum precipitation (PMP), unit hydrographs, and probable maximum flood (PMF). 7. Development of mathematical tools to express many physical phenomena in numerical form.

As a result of new knowledge of hydrological conditions, it has been found that some dams have inadequate spillway capacity to pass the so-called probable maximum flood. Also, earthquake conditions appear to be more severe in some instances than originally calculated, in other cases dams were not designed for earthquake loading conditions. Older dams and reservoirs need to be reanalyzed to ensure that they can still meet current safety standards. A special ICOLD Committee was formed in 1972 to prepare a survey of the effects of aging of dams.

G. 1/6 of the total river flow of the world is in the Amazon. 2. Variations in precipitation and streamflow. 3. Unavailability at times and places where needed. 4. Flood runoff often cannot be used economically. 5. Population have grown and regions have developed where readily usable water supplies were inadequate. 6. Much of the ground water is at great depth or in sparsely populated areas. Effective Use of Water Resources. Although the purpose of dams is well known, one needs to be frequently reminded about the important role they continue to play in providing the basis for civilization.
