Project Evaluation in International Development
Project evaluation methods used by the World Bank and the United Nations Industrial Development Organization are compared with regard to measures of value, use of shadow prices, discount...

Geodetic Monuments for Eccentric Property Corners
Problem areas in land information systems are identified and described and solutions are proposed. The main areas discussed include a method of equitable property taxation, replacement...

Finite Beams on Elastic Foundation with Restraints
A solution is presented of the differential equation of finite beams with elastic restraints, resting on a Winkler foundation in terms of the initial conditions at one end of the beam....

Intra-CBD Secondary Travel Patterns of Downtown Workers
Previous Downtown People Mover (DPM) feasibility studies have shown that the majority of the average daily DPM trips will be made by downtown workers during their travel to and from the...

CW Microwave Location of Voids Beneath Paved Areas
The problem of locating voids beneath paved areas is a perplexing and costly one. Usually voids are investigated by test borings, which is a discontinuous hit-or-miss process. The use...

Columns with Semirigid Joints
The influence of realistic semi-rigid end restraint on the strength and behaviour of real steel columns is investigated. An analytical procedure is developed which includes the effects...

Circular Wall Jets in Coflowing Streams
The mixing and diffusion of circular turbulent wall jets in coflowing open channel streams is discussed with the ratio of the jet to channel velocity varying from 2 to 30 and the depth...

Obtaining the Layout of Water Distribution Systems
An essential first step in the design of a municipal water distribution system is the determination of the locational placement or layout of the links of pipe that will form the system....

Bed Load Fluctuation: Applications
Based on the distribution of transport rate, the fluctuation of bed load and its application to hydrological measurement have been studied. The variance and coefficient of variation of...

Swell of Wyoming Montmorillonite and Sand Mixtures
Eight blends of silica sand and Wyoming montmorillonite clay (volclay) at varying proportions by weight were tested at three different temperatures (24°C, 38°C, and 66°C) to investigate...

Routing Graded Sediments in Streams: Applications
A one-dimensional numerical model has been tested in simulating the movement of well graded sediments through a stream reach. The model is applied to two laboratory flumes and two alluvial...

Sedimentology of Erect Vegetal Filters
In order to analyze sediment deposition in vegetated areas, it is necessary to develop relationships that define the steady-state sediment transport capacity of a given filter media. The...

Wind Pressures on Low Buildings with Parapets
The effect of parapets on the wind loading of low-rise buildings has been examined in the past, primarily under conditions of uniform flow not representing the variation of the mean speed...

Realistic Tolerances for Double-Tee Construction
This paper is mainly concerned with the problems of tolerance specification for precast concrete construction. Some articles have reported that constructed tolerances are much larger than...

Reconversion to Coal Firing at Crystal River
Units 1 and 2 at the Crystal River Plant of Florida Power Corporation were originally designed for coal firing in the 1960's, were converted to heavy fuel oil firing in the...

Pavement Roughness and Rideability: A State-of-the-Art Review
This paper reports on the results of a review of the literature and ongoing research concerned with pavement roughness and rideabiity. The material covers definitions and concepts, subjective...

Determination of Particulate-Nutrient Availability
A procedure for direct contact algal assay is described which provides quantitative data on phosphorus transfer from soil to algae in serial 14-day incubations. The algae/soil/liquid phases...

Soil Pressures Due to Aircraft Loans
Soil pressure gages were installed in a crushed limestone backfill of a bomb damaged runway. Measurements were made due to static and dynamic aircraft, C-130 and F-4E, wheel loads. Static...

Ice Engineering Design of Marine Piling and Piers
Design criteria and structure designs for pilings, piers, and docks subject to ice are presented. Included are estimates of stationary and moving horizontal and vertical ice forces, types...

Pulverized Coal Ash as Structural Fill
Untreated pulverized coal ash, consisting of fly ash with varying percentages of bottom ash, was used as a structural fill material to support the foundation of a new precipitator for...
