Numerical Modelling of Bed Evolution in Braided Channel Systems
The overall modelling approach adopted is based on an assumption of quasi-steady flow. The numerical algorithm is based on a split-operator approach, in which the flow energy equation,...
Yakima Remote Control System: Supervisory Control and Data Acquisition
The Yakima Remote Control System is a computerized supervisory control and data acquisition (SCADA) system developed for the operation of the Bureau of Reclamation's Yakima Project in...
Response of Floating Structures in a Directional Sea
A finite element numerical model is presented to predict the behavior of long floating structures in a multi-directional sea. A follow up numerical model analyzes an important but mostly...
Vortices at Vertical Intakes
This paper presents the results of an experimental investigation designed to predict the formation of weak, free-surface vortices at vertical intakes with a headrace channel. A weak vortex...
Design and Calibration of a 200-Foot Model Irrigation Border with a Computer Controlled Infiltrating Bed
A physical model of an irrigation border was constructed using a 200 ft long by 2. 5 ft wide tilting flume with a 3. 5 inch deep infiltrating gravel bed. The border was partitioned into...
Analytic Solution for Seepage from Saturated Soil Behind a Braced Wall
The locations of streamlines and equipotentials for two-dimensional flow in the vertical plane normal to a vertical retaining wall can be determined by various methods. Recent extension...
Cazenovia Creek Model Data Acquisition System
The purpose of the model is to reproduce river ice breakup phenomena for optimizing the design of an ice control structure. The performance of the ice control structure during a simulated...
Recent Developments in Hydrologic Instrumentation
The availability of space-age materials and implementation of state-of-the-art electronics is making possible the recent developments of hydrologic instrumentation. Material developments...
Development of a Practical Method Simulating Oil Spill Migration (OSPIM) in Soils
Many ground-water modeling studies can be performed on currently available microcomputers. The greatest problem associated with the proliferation of ground-water modeling software for...
Ground-water Modeling on Small Computers: Past, Present, and Future
The paper reports on research that concerns the possible development of numerical models being able to simulate practical cases of Oil Spill Migration (OSPIM) in soils. Such models can...
Investigation of Design Criteria for APM Guideways
Designers have relied mostly on the provisions of the American Association of State Highway and Transportation Officials (AASHTO) Standard Specifications for Highway Bridges. Sometimes...
Design Criteria Impacts on Guideway Development
A highly definitive design criteria or performance specification is frequently developed for new transit systems. The criteria are intended to protect the owner's interest...
Planning and Environmental Assessment of New Transit System
The guideway of the new transit system 'KANAZAWA SEASIDE LINE' which Yokohama City has started construction is designed as an elevated type throughout the line,...
The Aerometro Suspended Rail System
The unique flexibility of the Aerometro Suspended Rail System offers an excellent opportunity for addressing urban transit needs. It is capable of prefabrication off-site, relatively simple...
Safety Aspects of Detroit DPM Station Designs
The Detroit Downtown People Mover (DDPM), currently under construction in the Central Business District of downtown Detroit, offered a unique set of challenges to the architects and engineers...
Alignment Special Structures for Vancouver's ALRT
This paper describes the special long-span structures, offset columns, and bent structures used in situations where the standardized guideway components used in over 90 percent of the...
Downtown People Mover System Security: Detroit and Miami Responses
The Detroit and Miami downtown people mover (DPM) systems will be in uncontrolled environments in major urban central business districts. Both plan not to have personnel on vehicles or...
A New Alternative in Steel Construction?Partially Restrained Connections
Lack of formal training in methods as well as the lack of specific guidelines have limited the understanding and utilization of semi-rigid connection technology. A renewed interest in...
The Effect of Connection Flexibility on Steel Members and Frame Stability
With the advent of Load and Resistance Factor Design (LRFD) and the many existing moment-rotation curves for connections, the use of actual connection flexibility in the design process...
Utilization of Experimentally Obtained Connection Data in Assessing the Performance of Steel Frames
Data from over 70 separate experimental studies on steel beam to column connections are reviewed with particular reference to the joint's in-plane moment-rotation characteristic. More...
