Littoral Environment Observation Program
This paper presents a method for determining the longitudinal, transverse, and vertical dispersivities of a thick aquifer for a free convection tracer test using only measurements from...
Techniques for Automating the Process of As-Built Reconciliation
The approach utilizes an electronic digital 'ruler' capable of measuring distances to 100 feet with a resolution of 1/100 of a foot. This ruler interfaces to...
A Flat-Dilatometer Study of Lateral Soil Response
The effect of flat dilatometer penetration on the lateral stress conditions in soil around the dilatometer blade and the soil response against dilatometer diaphragm deflection were investigated...
Acoustic Silt Density Measurement
Significant savings can be achieved on the costs of operations for the deepening and maintenance of navigation channels and harbor basins in muddy areas provided that computations are...
Influence of Roughness on Velocity and Dispersion at Low Flow
Dependence of the hydraulic and transport characteristics of low flow on channel roughness is investigated. Empirical expressions are used to estimate roughness coefficient as a function...
Flow Parameters of Fluid Mud
A set of small-scale, high-resolution velocity and stress sensors based on rugged metal-clad hot wires and epoxy-encapsulated hot films is to be evaluated for its performance characteristics...
Streamflow Measurement and Analysis for Northwest Rangelands
Watershed hydrologic and sedimentation investigations on the Reynolds Creek Experimental Watershed in southwest Idaho were initiated in 1960. Major objectives of the watershed research...
Field Flow Measurement of Hydro-Turbine Efficiency
Performance tests were conducted at Great Northern Paper (GNP) Company's Weldon Hydroelectric Station. The purpose of the tests was to calibrate the Winter-Kennedy taps and...
Hydraulic Research--U.S. Geological Survey
Research at the Gulf Coast Hydroscience Center near Bay St. Louis, Mississippi, is being conducted in an indoor laboratory, and an outdoor laboratory. Much of the current indoor lab research...
Electronic Traffic Management
High technology has entered the world of traffic and transportation management with such new optical and electronic devices as transponders, retro-reflective stickers, microprocessors,...
Directional Wave Spectra Applications
These collected papers and their ensuing discussions presented at the September, 1981 symposium at the University of California on directional wave spectra applications examine the present...
Recent Development in Geotechnical Engineering for Hydro Projects
Eleven of the papers presented at three sessions of the ASCE Geotechnical Engineering Division at the 1981 International Convention are included. The papers are divided into two subjects:...
Cone Penetration Testing and Experience
Experiences and advances in cone penetration testing are reviewed in these papers presented in a technical session at the National Convention of the American Society of Civil Engineers....
Surveying Takes Another Giant Step Forward
The introduction of short-range electronic distance measurement in 1971 revolutionized surveying. Thousands of surveying and engineering firms across the U.S. today routinely use EDM for...
What Happens to Cities When the Gas Runs Out�
Many suburban-urban areas will be crippled by gas rationing; commuters may be unable to get to work until emergency procedures are in place. Some far-sighted communities, however, have...
Measuring the Effects of Man's Wastes on the Ocean
Understanding the ecological effects of municipal wastewater discharged into the ocean depends on data developed by reliable measurements. Municipal wastes are largely residential sewage...
A Hydrographic Surveyor's Most Memorable Day
Holbert Fear's most memorable day in a career as a hydrologist with the U.S. Geological Survey was in 1917, near Hanna, Wyoming. Fear was sent out to measure the flow of the North Platte...
