A Method to Treat Incident Wave Condition in Shallow Water Equation
A method to consider open boundary condition of the shallow water equation to analyze water surface wave and tide is employed in the finite element anaysis. This can be done by considering...
Mechanics of Mud Flows in Curved Channels with Uneven Beds
Most natural debris flows move through paths that are curved and that have significant bed topography. Owing to the dependence of the mechanics of wet debris containing substantial amounts...
Two Dimensional Nonequilibrium Transport of Nonuniform Sediment
Mathematical models based on diffusion and/or diffusion convection equations have been widely applied to study sediment transport in suspension. Some of the studies were reported by C.C....
Boundary Element Methods in Structural Analysis
Tutorial and state-of-art aspects of the Boundary Element Method (BEM) are combined with applications in structural analysis in order to provide information about the advantages of this...
Boundary Conditions of Tidal Model at River Mouth
A small grid is required to schematize irregular shape of shoreline in the vicinity of river mouth which limits the modeling area to be small. Tidal records along the boundary show no...
Scale Effects at Intakes Due to Boundary Layer Growth
Boundary layer development in hydraulic models of intakes based on Froude criteria can be poorly scaled because it is viscosity dependent. The potential for scale effects can be estimated...
The Tides Effects on the Dam Break Flood Wave
The accuracy of water level predictions downstream of the dam is dependent upon the breach evaluation, the correct estimation of the roughness coefficients and when the flood wave reaches...
Design Data of Kaplan and Bulb Turbine Units
Some basic statistical data covering geometrical and energy parameters for Kaplan and bulb turbine units are presented. These data are further compared as specific rations for both units,...
Project Constructability?A Contractor's View
This paper addresses a contractor's view of what can be done to improve project constructibility from the design through the actual construction of the project. It addresses...
Real-Time Project Tracking
Too often project tracking is based on a job costing program which charges costs to the project based upon invoices from vendors and payrolls of employees. The information obtained from...
Channel Tunnel, Texas Style
Two water supply pipelines under the Houston Ship Channel and Greens Bayou are an example of deep tunneling in soft ground. The navigable waters and the water-bearing silty soils in the...
Pyrites Hydroelectric Project, Canton, New York
This paper describes the Pyrites Hydroelectric Project in Canton, New York, an 8-MW project completed in December 1985. The key to its successful development was a team approach that included...
Sewage Plant Engineered for Value
The Camden County (NJ) Municipal Utilities Authority was formed in 1972 to cope with suburban growth that had overloaded 34 primary treatment plants. By the early 1990s, the Authority...
Economic Analysis of Canal Animal Protection Measures
Justification of canal animal protection measures has been, to a degree, driven by environmental and social constraints and as a result, large expenditures of funds to protect ungulates...
Stable Channels with Loose Boundary
Recently, G. Parker suggested that the lateral transport of downstream momentum due to Reynolds stresses should be included in the momentum balance used to calculate the boundary shear...
Uncertainty and Value Analysis in the Selection of Dam Modification Alternative
Objectives and attributes were decided by the dam and watershed requirements, value judgments of decision makers, quantified trade-offs between different attribute values, and technical...
Gas Transfer at the Water Surface: Measurements of Gas Concentration Fluctuations
The paper describes measurements of fluctuating gas (oxygen) concentrations by means of a polarographic microscope near the air-water interface. The objective is to demonstrate the feasibility...
Density Currents and Their Application in Hydraulic Engineering: Task Committee Progress Report
The Task Committee on Density Currents and Their Applications in Hydraulic Engineering operates under the Technical Committee on Hydrologic Transport and Dispersion. The Task Committee...
Survey of Soviet Space Welding Technology Development
Soviet engineers clearly recognize the potential value of welding for maintenance, repair, and fabrication of structures in space. The development of this technology has followed a steady...
Structural Art in the Lunar Environment
Building structures will be a necessary part of extending our presence on the moon. In designing and building these structures, aesthetic value will play a prominent role. History shows...
