A Hybrid Model for Storage Routing Through Rock Dumps
Construction of permeable structures across stream channels results in temporary impoundment of flood waters upstream of such structures. This happens because the hydraulic conveyance...

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...

Flood Hydrology Modeling: U.S. Virgin Islands
To develop a consistent basis for evaluating existing flooding problems and for planning activities to reduce future flood damage, a watershed modeling project was initiated by the Government...

The Dallas Floodway Project
This paper explores the history of the Dallas Floodway project, past performance of the project under various flood conditions, recently updated hydrologic and hydraulic evaluations, and...

Monte Carlo Approach to Spillway Design Floods
This paper shows the use of a daily stochastic streamflow model for the calculation of the hydrograph for spillway design. Most of the literature related to the topic deals with the problem...

An Analysis and Comparison of Probable Maximum Floods with 10,000-year Frequency Floods and Maximum Observed Floods for Spillway Design
The use of deterministic probable maximum floods are supported in part by the conclusions of an Interagency Work Group formed to address the following questions: (1) Is it within the state...

Criteria for Selecting a Reservoir Routing Method
Results of an investigation comparing dynamic and storage reservoir routing applied in dam safety analyses are presented. Outflow hydrographs computed by these reservoir routing methods...

USDA-Water Erosion Prediction Project (WEPP)
The USDA-Water Erosion Prediction Project (WEPP) will develop improved erosion prediction technology based on modern hydrologic and erosion science that will be process-oriented and conceptually...

Sedimentation Impacts on a Pumpback Storage Facility
Concern over future sedimentation impacts at a proposed pump storage hydroelectric facility at Lake Francis Case on the Missouri River led to use of a numerical model to analyze lake hydrodynamics....

Optimization of Complex Hydrologic Models Using Random Search Methods
The primary objective of automated calibration of complex conceptual hydrologic simulation models is to find the global optimum of a specified response surface. While direct search techniques...

Automatic Calibration of Conceptual Rainfall-Runoff Models
An automatic calibration strategy applied to land and channel components of the National Weather Service River Forecast System is outlined. Aspects discussed include the objective function...

Fault-Tolerant Design for Data Acquisition and Flood Forecast Systems
An innovative fault tolerant flood warning system is currently being installed in the Passaic River Basin. The new system is designed to automatically tolerate the failure of major components...

A Comparative Study of Different Base Isolators
A comparative study of the effectiveness of four different base isolators is carried out. The structure is modeled as a rigid mass and the accelerograms of the North-South component of...

Response of Structures to Horizontal-Vertical Earthquakes
In the present work, the responses of a class of hysteretically nonlinear structures subjected to the combined horizontal and vertical random ground accelerations are studied. A massless...

Cracking of a Tilt-Up Structure Due to Dynamic Loads
The extensive cracking of a tilt-up reinforced concrete structure is discussed. The site investigation revealed horizontal cracks at two feet to seven feet above a mezzanine level which...

Probabilistic Models of Fatigue Crack Growth
The reliability of a structure against metal fatigue is a problem that has been of concern to engineers for a very long time. This problem was one of the first to be approached probabilistically,...

Applications of Fiber Bundle Model to Structural Engineering
The bundle failure time has been studied extensively for both deterministic and random loads. The objective of this paper is to apply results in these studies to the dynamic analysis of...

Seismic Response Component in the Risk Assessment of Dams
The risk analysis model for dams that is discussed in this paper considers the probability of an initiating event and the following conditional probabilities of the system response, the...

Simplified Steel Compression Member Design
The objective of this paper is to present a simplified method of designing steel columns subjected to axial loads and moments for use in situations where automated design methods are inappropriate....

Comparisons of Full Scale and Wind Tunnel Model Response to Wind of Long Span Bridges
There are several vital reasons for measuring the response of full scale structures to wind and comparing the results to models - both experimental and analytical - employed in design....
