Report flood protection at bridge crossings : draft
Techniques for the design of stable rock-riprap protection in the vicinity of bridge crossings are presented. Hydraulic properties of the crossings are computed from methods derived in other sources, and the properties are ... -
Vertical momentum transport over mountainous terrain
High-resolution pictures obtained with a handheld camera during the earth-orbital photographic mission of the Apollo IX spacecraft provided a unique opportunity to map the areal extent of gravity waves over the southwestern ... -
Thermal modification of the troposphere due to convective interaction
The erosion and subsequent mixing to the environment of the updraft of mesoscale convective clouds is examined and modeled as a mechanism for the thermal modification of the cloud environment. Atmospheric soundings made ... -
Influence of absolute pressure on the cooling of a plate by impinging air jets
An experimental investigation to determine the effect of absolute pressure on the convective heat transfer coefficient for a hot plate cooled by impingement of air jets upon it was executed as proposed by Haberstroh and ... -
Surface-air energy exchange over eastern Venezuela as related to streamflow and cumulonimbus cloud systems
Solar and net radiation measurements made during the Venezuelan International Meteorological-Hydrological Experiment (VIM-HEX) conducted in Venezuela in the summer of 1969 are discussed, and the results presented in two ... -
Maintenance station location through operations research at the Wyoming State Highway Department
The purpose of the investigation reported in this paper is to develop mathematical models by means of operations research techniques to optimally allocate scarce resources used in highway maintenance. Various maintenance ... -
Interaction of a wall-jet with a shear flow
An experimental investigation of a flow field resulting from the interaction between a spreading turbulent wall jet on a smooth surface and a shear flow was conducted. The combined flow was formed by a downward circular ... -
Research and development technique for estimating airflow and diffusion parameters in connection with the Atmospheric Water Resources Program : interim report
This report presents a summary of the research and tentative findings on the use of scaled topographic models and laboratory techniques to study the transport and dispersion of cloud seeding material over mountainous ... -
Laboratory simulation of airflow and atmospheric transport-dispersion over Elk Mountain, Wyoming : technical report
A stably stratified airflow over an isolated mountain was simulated in a wind tunnel and transport-dispersion properties were investigated. Geometric, dynamic and thermal similarity were considered for stably stratified ... -
Numerical and wind tunnel simulation of stratified shear layers to nonhomogeneous surface features
Two-dimensional airflows over various nonuniform surfaces in a stratified atmosphere are studied both numerically and experimentally. Three problems are investigated, classified by the effect of the external forcing functions ... -
Basic and regional characteristics of streamflow in the upper Colorado River basin : interim report
This report describes the first phase of a research project concerned with two somewhat related subjects: 1. The study of the flow regimen of the rivers in the Upper Colorado River Basin and their relation to differences ... -
Reaeration in open-channel flow
Reaeration, the physical absorption of oxygen from the atmosphere, is the primary process by which a stream replaces oxygen consumed in the biodegradation of organic wastes. The reaeration process in a stream is characterized ...
