Probability Based Evaluation of Spillway Capacity
Spillway adequacy could be evaluated more objectively if estimates were available of the probabilities of discharges up to the Probable Maximum Flood (PMF). As a first step in making such...

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...

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...

Recent Developments of the Finite Strip Method
The finite strip method is approaching a state of maturity as a structural analysis technique, as the well known finite element method has done. Two comprehensive (although somewhat dated)...

Rescuing the Everglades
After a century of trying to control Florida's Everglades, water management officials have decided that cooperating with nature is better. A new strategy known as the Rainfall...

Engineering Hydrology
The Surface Water Hydrology Committee, ASCE Hydraulics Division, sponsored this first Symposium on Engineering Hydrology. The Symposium was held jointly with the ASCE National Conference...

A Stochastic-Conceptual Reservoir Inflow Forecasting Model
The development of a method to improve real-time forecasting of reservoir inflows for the purpose of minimizing water loss through spillage is presented. Streamflow forecasts are computed...

Advance Prediction of Flow-Induced Variations
Frequency analysis of hydraulic vibrations has been applied using a transfer matrix and impedance method. The computer program is given for the self-excited and forced vibrations, together...

Landslide Dams in Japan
Damming of rivers by landslides is common in Japan because widespread unstable slopes and narrow valleys exist in conjunction with frequent hydrologic, volcanic, and seismic landslide...

Frequency Domain Analysis of a Tank-Soil System
The dynamic response of an elastic cylindrical tank supported on a rigid base under a harmonic vertical excitation is analyzed taking into consideration its interaction with the foundation...

Adaptation of Modal Testing Procedure to Shaker Tables
This article presents a technique for adapting current modal testing procedures to shaker table tests commonly used for qualification tests of nuclear and space related equipment. It involves...

Stochastic Response of Structures with Appendages Containing Fluids
Following a perturbation technique a procedure is developed to compute the modal properties of a system consisting of a fluid containing appendage attached to a multi-degree-of-freedom...

Co-ordinated Microcomputer-Based Rain Data Network and Modeling Environment
A co-ordinated microcomputer controlled rainfall collection network has been designed which includes drop counting precipitation sensors, tipping bucket raingauges, Z80-A microprocessor...

Rainfall-Loss Parameter Estimation for Illinois
The U. S. Geological Survey is currently conducting an investigation to estimate values of parameters for two rainfall-loss computation methods used in a commonly used flood-hydrograph...

Precipitation Analysis in Clark County, Nevada
The Clark County, Nevada Department of Public Works retained Black & Veatch in March 1985 to conduct a study of the Flamingo Wash and to recommend flood protection facilities,...

Characteristics of Intense Storms in Kansas
This paper examines point-rainfall characteristics of intense storms in Kansas. Hourly rainfall records were analyzed for 1006 intense storms selected from some 1800 station-years of data....

Real-Time Monitoring and Flood Forecasting
An automated flood warning system is now serving the 2,700,000 residents of Houston, Harris County, Texas. Real-time rainfall and river level data from more than 150 sensors are automatically...

Prediction of Sediment Yield for Southern California Watersheds
The objective of this paper is to present a scientific method based on multiple linear regression analysis between the sediment yield per square mile and a number of physically realistic...

Storm Dynamics in the Lake Ontario Region
A program package, RAINPAK, was written to develop appropriate rainfall input, based on concepts of the physical processes behind the temporal and spatial distribution of storm rainfall...

Intense Storms and the Runoff Coefficient
During prolonged, intense storms the runoff coefficient increases in value and approaches one irrespective of the vegetation and soil characteristics of the watershed. As the runoff coefficient...
