Microtunneling Meets Mother Nature
The world's first ocean thermal energy plant is getting a double. Microtunneling the second ocean intake 80 ft under the Pacific Ocean is proving challenging, partly due to...
Effects of Sea Surface Movement on Offshore Structures
Examinations are made of the effects of the sea surface movement on the fundamental model response of deep-water, Wave-excited offshore structures. These effects are accounted for by using...
Seismic Behaviour of Tall Guyed Telecommunication Towers
This paper presents results of a detailed numerical modelling study of two guyed telecommunication towers subjected to seismic excitation: a 107-m (350 ft) tower with six stay levels,...
Active Control of Axial Forces in Beam String Space Frames
The present work discusses a formulation for active control of axial forces of strings in beam string structures to dynamically and/or statically reduce the responses, and proves both...
A Shape-Finding Finite Element Analysis for an Equally-Stressed Surface in Membrane Structures
A finite element method is proposed to obtain an equally-stressed surface in a membrane structure, where the displacements and rotations of a membrane are in general finite and nonlinear....
Stability Analysis of Optimal Active Control Systems with Time-Delay and Other Influence Parameters
This paper presents a theoretical solution for determining the stability region of multi-story buildings equipped with one active tendon controller on a certain floor. In this theoretical...
Digital Signal Processing Techniques for Active Structural Control
In the past, implementation of active structural control strategies employing PC-based hardware has been problematic due to excessive computational times required for processing the measured...
A Multi-Dimensional Transport Model Utilizing a Characteristic-Galerkin Approach
A multi-dimensional transport model based on the RMA series of finite element models has been developed utilizing a characteristic-Galerkin approach. This paper examines the application...
An Energy Based Model for Coastal Bays and Lakes
The North American Great Lakes have numerous tributary bays and small lakes along their coastline that open directly to the Great Lakes through natural or engineered channels. As a consequence...
Boston's Backup Water Supply
For fifty years, Boston's sole real source of water has been the Hultman Aqueduct, but now final design is almost complete on the MetroWest Supply Tunnel, a new, larger conduit...
The Daytona Beach Large Wave Event of 3 July 1992
The fundamental mechanisms behind the anomalous large wave which struck Daytona Beach on 3 July 1992 are addressed. Although the wave was originally believed to have resulted from a submarine...
Evaluation of a Third-Generation Wave Model for the U.S. Atlantic Coast
Accurate description of surface wind fields in ocean spectral wave modelling is of critical importance to estimating storm - induced wave conditions along a coastal reach. A new approach...
Nonlinear Effects on Wave Envelope and Phase
The representation of second-order random waves is examined in terms of the effect of second-order nonlinearities on the wave envelope and phase. Theoretical expressions describing the...
Optical Remote Sensing of Wave Surface Kinematics
The measurement of the directional properties of surface slopes, velocities and accelerations is difficult, even in the laboratory, under conditions of steep, random and short-crested...
Breaking Wave Measurement by a Void Fraction Technique
Breaking of steep surface gravity waves in seas under moderate to strong wind forcing always involves the entrainment of air into the water column below the air-sea interface. As such,...
Historical, Current and Upcoming Regulation Schedules for Lake Okeechobee
This paper reviews historical information of regulation practices for Lake Okeechobee since the beginning of the century. It also describes and analyzes the multipurpose objectives associated...
Fort Bend County Surface Water Supply Study
Fort Bend County encompasses approximately 876 square miles in southeast Texas near the Gulf of Mexico. The County's sole source of potable water is groundwater, which supplied 28 million...
Surface Water Withdrawal Permits Programs for Humid Regions
In humid regions of the U.S., where control of surface water withdrawal is traditionally under the riparian doctrine, there are few strong regulatory programs to restrict water use. In...
Surface Water Quality Modeling in the Rio Grande
The City of Albuquerque (City) in New Mexico owns and operates the Southside Water Reclamation Plant (SWRP), which discharges an average of 200623 m3/d...
Recommendations for Standards in Hydraulics
Prepared by the Task Committee on Recommendations for Standards in Hydraulics of the Hydraulics Division of ASCE. This report investigates whether...
