Infiltration Wells in the Lakes Around the Future Markerwaard Polder
Drainage and reclamation of the Markerwaard polder in the Netherlands may cause damage to buildings and infrastructure in the eastern part of North-Holland because of subsidence. Drawdown...
Manhole Junction Flow
When a sewer surcharges, a basement floods, or sewage overflows, the likeliest source of the problem is sewer junction manholes. Poorly designed ones act as bottlenecks. Study of a few,...
Design of Drilled Piers in the Atlantic Piedmont
The philosophy and methods of drilled pier foundation design in the Atlantic Piedmont are described. Consideration is also given to the unique characteristics of decomposed metamorphic...
Drilled Piers in the Piedmont?Minimizing Contractor-Engineer-Owner Conflicts
Drilled piers are used extensively in the Piedmont Physiographic Region, deriving support primarily from end-bearing on hard rock. Cost extras and contractor-engineer-owner conflicts are...
Analysis of Berth Operability by Utilization of Agitation Models
Agitation models are utilized in order to predict the operability of berths for ship unloading purposes. Usually, in such models all ship displacements are measured and when one of them...
Building Frame Analysis in Basic
Moment distribution has, for the past 30 years, been the most popular method of analysis for statically indeterminate structures. Programmed in Basic for the microcomputer with relative...
Long Crested Weirs
A method has been developed to integrate and evaluate the head relationship between canal weirs and turnouts. The objective is to minimize flow variations through the turnout and at the...
Air Regulated Siphons as Irrigation Canal Outlets
This paper investigates the possibility of using air regulated siphons as outlets from irrigation canals. Although a solution to a specific problem is sought, it is recognized that the...
Air Chamber Surge Tanks in High Head Hydro Plants
The U. S. Army Corps of Engineers Alaska District considered an air chamber during the design of the 'Crater Lake phase of the Snettisham Project near Juneau, Alaska. A conventional...
Update: Fluidization for Tidal Channel Maintenance
Flow emanating from perforations in a pipe under a non-cohesive media, such as sand in the coastal environment, can fluidize the overlying media. The fluidized sand can be readily moved...
Low Head Dam Safety Studied with Hydraulic Models
Use of physical models to study the hydraulic jump or submerged roller action created as water overflows low head dams provides an opportunity to develop design criteria for various structure...
Gradation and Layer Thickness Effects on Riprap
Since riprap has become a costly and in some areas, scarce commodity, proper design maximizing the level of protection with a minimum rock size and layer thickness is an important goal....
Mechanics of Embankment Erosion During Overflow
Thousands of dams built in the United States have a potential to be overtopped by flood flows. It is necessary to understand the mechanics of embankment erosion in order to evaluate the...
Low Head Hydropower Finite Element Analysis
Finite element analysis provides a means of predicting the flow conditions resulting from the operation of a proposed hydropower facility. The results of a finite element flow analysis...
Thermodynamic Factors in Evapotranspiration
Many of the methods discussed in this paper are refinements of procedures presented in the report 'Consumptive Use of Water and Irrigation Water Requirements'...
Prediction of Deformations Due to Heat Curving
This paper summarizes the state of the art in the thermal deformation techniques. Alternate analytical methods are described. The limitations and accuracy of these models are noted, and...
Design of Bridge Piers Against Ship Collision
Design rules for unprotected bridge piers, using uniform safety requirements, are proposed. The selection of an appropriate design vessel is based on a risk assessment model which uses...
The GEV Distribution in Drought Frequency Analysis
Three decades have passed since A. F. Jenkinson found the general solution to the Stability Postulate, which is the condition that all the extremes must meet, and after him that solution...
Nonlinear Axisymmetric Uplift of Circular Plates
A formulation of a method of analysis of the nonlinear axisymmetric response of the bottom plate of a liquid storage tank under uplifting forces is presented. At first, the plate is assumed...
Probabilistic Models of Fatigue Crack Growth
The reliability of a structure against metal fatigue is a problem that has been of concern to engineers for a very long time. This problem was one of the first to be approached probabilistically,...
