Watershed Characteristics and Hydrological Parameters vs. Sediment Yield?Northern Regions of Pakistan
In order to manage, restore, or effectively maintain a watershed it is necessary to know what is really going on inside that watershed, which includes the effects of watershed and hydrological...

Stable Slopes of Alluvial Channels
An alluvial channel responds to the variation in the incoming sediment by changing its cross-section and especially the slope. Regime relations formulated by Lacey (1930) and many subsequent...

Use of Pilot Projects for Technology Transfer in Developing Countries
Pilot projects of various sizes - 25-1100 ha of farm land - have been used to demonstrate new concepts in water supply and farming practices in Sri Lanka, India and Pakistan, and they...

Case Studies of Utilizing a Flexible Automated Supply in Developing Countries
The need is seldom questioned for a water supply that is available when the crop needs it - frequency; at a rate that can be satisfactorily used; and for a duration that provides just...

Manufacturing Planning 4 ? 440 MW Turbines Short Delivery
DBS Escher Wyss Inc. is building the largest turbines ever to be manufactured in Canada for the third expansion of the Tarbela project in Pakistan; four (4) Francis turbines each rated...

Flexible Irrigation Supply Pilot Projects?Part II: Sri Lanka, Pakistan, India, Egypt
The Sri Lanka project covers about 150 one hectare farms on the lower half of a unit served by one distributary. The upper part, because of delays in construction, was left as an earth...

Stochastic Optimization of Conjunctive Use in Pakistan
This paper describes an optimization analysis of conjunctive use of ground and surface water that incorporates stochastic inflows and regional variations in groundwater quality and availability....

Sediment Yield and Mean Annual Discharge from Watersheds in the Indian Subcontinent
Measurements of sediment deposition in reservoirs located in the Indian subcontinent (India, Nepal, Pakistan) indicate that the rate of sedimentation is much higher than predicted during...

Tarbella?Third Extension Project Units 11 to 14: 440 MW Francis Turbine Design
At Tarbela Dam in northern Pakistan, the Third Extension Project, units 11 to 14 of 440 MW each, is presently under construction. When completed in 1992, the multipurpose hydro-irrigation...

Dynamic Analysis of Existing Tarbela Intake Towers
According to general practice at the time of the design, the pseudostatic method of applying earthquake loading was used. The basic acceleration was 0. 1g. A post-construction seismological...

Engineering Implications of Impoundment of the Indus River by an Earthquake-Induced Landslide
Historical records and physical evidence indicate that in the Himalayas of northern Pakistan a huge landslide dam was caused by an earthquake in 1840. The dam blocked the Indus River,...

Landslide Dams
Processes, Risk, and Mitigation
Landslide dams have proved to be both interesting natural phenomena and significant hazards in many areas of the world. A few of these blockages attain heights and volumes that rival or...

Deferred Drainage?Prudent Policy or Tactical Folly?
The practice of deferring drains has not always worked out as planned. This is particularly true of large outlet drains such as the San Luis Drain in the Central Valley of California and...

Recent Development in Geotechnical Engineering for Hydro Projects
Eleven of the papers presented at three sessions of the ASCE Geotechnical Engineering Division at the 1981 International Convention are included. The papers are divided into two subjects:...
