Size Characteristics of Debris Flow Deposition
The size distribution of debris flow deposition is extremely wide which may contain nearly all particles from clay and colloid to boulder. Particle size and composition have very important...
An Approach to the Calculation Method of Mean Sediment Size
Mean sediment size is an important parameter expressing the characteristics of sediment. Several calculation methods of mean sediment size which are popular at present almost have some...
Bed Load Prediction in Steep Mountain Rivers
The characteristics of the stream channel morphologies in a very steep mountain ravine are explained by the data obtained through the longterm field observation. The bed load transportation...
Particle Dynamics and Bed Level Adjustments in a Mountain Stream
The focus of the study was the interaction of coarse bedload sheets with a near-static bed. At a critical discharge bed sediment was transported from upstream sources through the study...
Coarse Sediment Transport and the Maintenance of Fish Habitat in the Upper Colorado River
An analysis of the relation between discharge and boundary shear stress is presented for an alluvial reach of the Colorado River near Grand Junction, CO. The analysis indicates that the...
Width Adjustment: Relative Dominance in Unstable Alluvial Streams
The mechanisms that control the relative dominance of width adjustment in unstable streams are described. Specifically, the role of the following factors affecting the fluvial environment...
Toe Scour Protection Methods
Toe scour protection is an important element in bank protection projects because undermining by scour at the toe is one of the major causes of failure of bank protection. Existing toe...
Relation of Unit Gravel Discharge to Mean Velocity
In sand-bed streams, the unit discharge of sand varies approximately with the fifth power of the mean velocity and inversely with the median diameter of the bed sediment. Similar relations...
Bed Material and Numerical Modeling in a Gravel/Cobble Bed Stream
The characteristics of bed material in a cobble or gravel river and their use for numerical simulation of flushing flow needs are discussed. There are three types of bed material: 1) material...
Local Scour Potential for Large Bed Material with Shallow Tailwater Depth
Jet momentum acting on a bed particle and submerged jet diffusion theory were employed to derive scour prediction formulas in a plunge pool. Semi-theoretical formulas were suggested for...
Carpet Flow Analysis
Under very high flow conditions, sediment may be transported either in a suspension or by carpet flow, as defined by Bagnold. This study examines the theoretical conditions for carpet...
Structures Congress XII
This proceedings, composed of two volumes, contains the papers presented at the American Society of Civil Engineers (ASCE) Twelfth Structures Congress held in Atlanta, Georgia, USA, April...
Computer-Integrated Construction
Computers have been used quite successfully as replacements for manual drafting, but to stop there seriously underuses the potential of computer aided design. By using the computer's...
The Key is Constructability
Construction generally involves the collective efforts of owners, designers, contractors and suppliers. During the design phase, the engineer should be mindful of such critical elements...

In Rehab We Trust
Glulam structures will be durable and last for a long time provided structural elements are protected from water and moisture. Once water is allowed to come into direct contact with glulam...
America's Pavements: World's Longest Bathtubs
Pavements are the most unusual structures designed by civil engineers. Water flows through their tops, bottoms and sides but because pavements are relatively flat, flows out again very...
