Mechanics of Washout of an Erodible Fuse Plug
Laboratory and field experiments are described that were undertaken to demonstrate feasibility of fuse plug in spillway of major dam for application in spillway of Oxbow dam on Snake River...

Some Aspects of Surface Water Wave Scale Effects
Model studies of water gravity waves generated by moving pressure disturbance including study of scale effects due to surface tension is presented; effects on water (ocean) surface by...

Interfacial Mixing in Stratified Flow
Description of apparatus which permits counterflow of 2 superposed streams of different densities to be maintained for period of time over appreciable length of uniform passage; velocity...

Scour at Bridge Crossings
Relationships are proposed for prediction of scour at piers and abutments for case in which sediment is supplied to scour hole; relationships were obtained from combination of approximate...

Tests on Prestressed Concrete Embedded Cylinder Pipe
Results of first full-scaled combined internal pressure and external load tests ever made on 60 in. prestressed concrete embedded cylinder pipe, designed according to AWWA Specification...

Prediction of Cavitation Damage
Cavitation damage theories since 1919 are cited and discussed; non-dimensional number, called cavitation damage number, is proposed, based on concept of dynamic indentations produced by...

Attenuation of Stress Waves in Bi-Linear Materials
One-dimensional wave equations are derived and it is demonstrated that, beyond given distance from surface, intensity of peak stress and particle velocity depends only on single parameter;...

Theory of Wave Agitation in a Harbor
First order theory for value of wave agitation in simple basin caused by incident periodical gravity wave is presented; influence of shape of entrance, beach, and wave traps on value of...

Vibration of Gates during Overflow and Underflow
Violent vibrations may occur at dam or weir gates being subjected simultaneously to overflow and underflow; model studies have been made to evaluate frequency and magnitude of exciting...

Dynamic Testing of Pavements
Each time vehicle passes over pavement, surface is deflected and rebounds, creating strain conditions for 0.01 to 0.1 sec; methods used in Netherlands for simulating and studying such...

Vibrations and Stability of Plates under Initial Stress
Equilibrium of plates, under initial stresses uniformly distributed across plate thickness; equations derived by B.de SAINT-VENANT by considering isolated plate element; paper presents...

Bearing Capacity of Floating Ice Sheets
Collapse of floating ice sheets under load is estimated on basis of rigid-plastic plate on elastic foundation for various loading and boundary conditions; results are compared with field...

Dynamic Elastic-Plastic Analysis of Structures
Finite difference method is presented; design of structure to with-stand h-p loadings of transient or time dependent nature such as nuclear blasts, requires abandoning conventional requirement...

Predicting Storm Runoff on Small Experimental Watersheds
Careful estimates of runoff are required for design of flood-retarding and channel-stabilizing structures, and bridges and culverts in small upstream watersheds; based on field experiments,...

Periods of Framed Buildings for Earthquake Analysis
Shear, bending, rocking and translational periods of cantilever beams with linearly varying shear and flexural rigidities, and with or without concentrated mass at their top, are computed...
