Microcomputer Graphics Flood Stationarity Test
Only records that correspond with present river conditions should be used with flood frequency analysis when forecasting. A microcomputer test is discussed which aids in selecting appropriate...
Flood Peak Program for Urbanizing Semi-Arid Areas
This paper describes a microcomputer program for flood peak determination based on a highly modified version of the Rational method developed by M. E. Zeller, which employs the Soil Conservation...
APM System Performance and Guideway Design Parameters
Automated People Movers (APM) are a relatively new form of transportation system becoming popular over the last twenty to twenty-five years. They are characterized by fully automatic and...
Parametric Analysis of APM Operational Components: Stopping Policy, Stations and Headway
This study examines generically relationships among the three parameters using a single line transit system. Optimization models are developed to determine the optimum number of stops...
Libby Rereg's Combined Spillway and Powerhouse
The existing powerhouse at Libby Dam, located near Libby, Montana has four generating units for a total of 420 MW. Provisions have been made which will allow doubling the plant rating...
Obtaining Reliable Data from Fragility Tests
The parameters discussed in this paper are the same as those present in normal seismic qualification testing. These parameters behave differently in high level acceleration tests and their...
Principles of Probabilistic Characterizations of Soil Properties
Sources of uncertainties affecting characterization of soil properties in a homogeneous soil layer include inherent spatial variability, systematic test bias, random test errors, calibration...
Update on Impact Effects in Nuclear Plants Part III?Review of Heavy Object Drop
The consequences of an accidental drop of a heavy component from a lifting device in a nuclear power plant are required to be evaluated even though the device may have been designed using...
Security of Unattended Pipeline Stations
The ultimate purpose of a security system is to maintain equipment and service in a normal operating condition or to restore the equipment and service to normal operating condition as...
Prediction of Peat Settlement
Compression of peat and organic clay deposits is characterized using a simple rheological model in which structural viscosity is assumed to be linear. The model utilizes three empirical...
Soil Analysis and Dredging
Analysis of soils before dredging can make or break a dredging project. It is seldom possible to obtain all of the information needed for selecting equipment and estimate outputs. The...
Selecting a Dredge Pump
While it is not necessary for the dredge operator to know how to design a dredge pump, the ability to select one that meets his project requirements is essential to insure the success...
Current Issues in Rock Dredging
An attractive alternative to the use of explosives for deepening shipping channels is the improvement of the rock cutter suction dredger. But, assessing the capability and design parameters...
Evaluating Pump Characteristics in Developing Countries
How do you assess normal operating characteristics for pumps used in small water supply systems when no information on the pumps is available and when the technicians have little technical...
Better Ways to Finance Stormwater Management
A lack of adequate funds is the principal impediment to local governments in developing stormwater management programs. Several municipalities in the U.S. assess user charges to be paid...
CE Computing Basics: Highway Vertical Profile Program
A program is explained step-by-step which can reduce the computation time involved in writing a highway vertical profile computation program. The program is written in BASIC. Once the...
Let's Consider Land Treatment, Not Land Disposal
The regulations that control operation and design of land treatment systems are discussed. A solution to control ground water pollution must consider all potential impacts. Pretreatment,...
8-Story Building Moved to Avoid Wrecker's Ball
In Bogota, Colombia, a 7000 ton (15400kips) was moved almost 100 ft (30 m) to make way for a much needed highway arterial. Instead of wrecking the structure, an apartment building in a...
In Situ Soils Measuring Devices
Soils engineering is as much art as science�� mostly because techniques for measuring soil parameters leave much in the realm of estimation. Developing instrumentation practices and equipment...
