Embankment Overtopping?Case Histories
Because many existing dams are subject to overtopping, there is a need to understand embankment behavior during an overtopping event. Understanding of this behavior will allow evaluation...

Predicting and Minimizing Embankment Damage Due to Flood Overtopping
Under a contract with the Federal Highway Administration and Bureau of Reclamation, Simons, Li & Associates, Inc. (SLA) is conducting an overtopping damage study to evaluate various...

Limitations of Saint Venant Equations to Model Flood Waves
The subject of this paper is in direct contrast to all previously known research efforts. Previous effort has focused on simplified forms of Saint Venant using approximate routing models...

River Wave Response to the Friction-Inertia Balance
The changing character of the solution of the Saint-Venant equations for river flow problems with the dimensionless parameter F//I reflects a changing balance between friction and inertia....

Infiltration as a Dependent Variable in Modeling Furrow Irrigation
Most surface irrigation models assume that infiltration is independent of surface flow hydraulics. However, wetted perimeter has been shown to significantly affect infiltration in furrows....

Measures Against Wind-Induced Vibrations of Bridges
The design of very flexible structures, such as long-span steel bridges, are frequently governed by wind-induced vibrations. This paper introduces the present situation of the cable-supported...

Wind Buffeting of Cable-Stayed Bridges During Construction
Some of the dominant loadings on a cable-stayed bridge during construction are a result of the non-uniform vertical and horizontal gust forces on the deck and the associated dynamic response...

A Linked Stream-Aquifer System Model
A linked stream-aquifer system (LISAS) model is described. This model includes a deterministic sequential flow simulation component which generates hydrographs of surface runoff and deep...

Kinematic, Diffusion and Dynamic Catchment Modeling
This paper reports on a series of tests aimed at developing improved procedures for catchment routing. The objective is to compare kinematic and diffusion models within several scenarios...

A Flood Prediction Geographic Information System
The paper discusses a GIS that derives kinematic wave model parameters using stream network, elevation, and basin boundary data. Various approaches are being investigated for estimating...

Safety Design Flood for Too Wide Creek Dam
This paper presents an example application of the procedure developed by the ASCE Task Committee on Spillway Design Floods for a dam on the Too Wide Creek. The example was developed from...

Time of Concentration in Small Rural Watersheds
A comparison was performed between the exponents of the independent variables L, S and i of the four-parameter time of concentration equation and eleven frequently encountered equations....

Dynamic Response of Massive Block to Transient Rayleigh Waves
The study explores the dynamic behavior of a rigid massive block placed on a homogeneous elastic half-space soil medium and subjected to transient Rayleigh waves. The treatment of the...

Full-Scale On-Site Wind Induced Data From a Tall Building
Under the sponsorship of the National Science Foundation (NSF), a large amount of data accumulated in a study of the behavior of a tall building under the influence of winds will be made...

Prediction and Measurement of Wind Response: Case Story of a Wind Sensitive Building
The wind-induced horizontal accelerations of a 43 story office tower in New York City were monitored during 11 occasions over a period of about six months. The building dates back to the...

Performance of Viscoelastic Dampers in World Trade Center Towers
The viscoelastic damper was conceived and developed as a part of the structural design for the Twin Towers of the World Trade Center, New York. They are an integral and an essential part...

Transient Response of Wind-Induced Internal Pressures in Buildings
The paper refers to a new experimental approach applied in a boundary layer wind tunnel experiment to test the transient response of the wind-induced internal pressure in a building when...

Wind Forces Measured on a Tall R.C. Chimney
This paper describes some aspects of an analysis performed on measurements of a variety of parameters relating to the wind, wind forces on and the response of a tall chimney. The results...

Fault Identification by Seismic Impact Load Techniques
The propagation of seismic waves generated by impact loading across a normal fault in carbonate rock was investigated by the seismic refraction technique. The field records were reduced,...

Wind-Induced Response of a Tall Building and Comparisons With Wind Tunnel Predictions
This paper describes the measured wind-induced response of a tall office tower and comparisons made with wind tunnel studies of the building. The use of an innovative structural system...
