The Durability of Rubble Mound Armour in Service ? A Case Study
Over the past decade, the ongoing monitoring of Gold Coast rubble mound structures in service has demonstrated a serious loss of durability over a period of time in the rock units after...
RCC for Rehabilitation of Dams in the USA-An Overview
The use of roller-compacted concrete (RCC) has rapidly become a powerful new tool in the USA for engineers involved with the rehabilitation of existing dams. Starting in 1980, RCC has...
Design and Proposed Construction Techniques for Pangue Dam
The paper describes the site conditions, design and proposed construction methods for the 115 m high Pangue Dam, Chile's first RCC dam. Trial mix design work and test embankments...
Roller Compacted Concrete Arch/Gravity Dams?South African Experience
The paper traces the development of roller compacted concrete (RCC) dams in South Africa, and in particular the application to arch/gravity dams. The Department of Water Affairs and Forestry...
A Review of Design Criteria for High RCC Dams
The 1980s could be considered to be the decade during which roller-compacted concrete dams came of age. This economic method of construction is sufficiently proven that very large dams...
Construction of Urugua-I RCC Dam
Considerations concerning the RCC construction process and its relation with the design and quality are analyzed. The paper contains topics related to the experience obtained at Urugua-i...
RCC Dam Design Concepts Versus Construction Conditions for Stagecoach Dam
The Stagecoach RCC dam was constructed using current state-of-the-art knowledge and the geotechnical approach to roller compacted concrete (RCC) mix design. The design was prepared in...
Thermal-Structural Analysis Methods for RCC Dams
Current procedures for evaluating temperature control and the placement of contraction joints in roller compacted concrete dams are not always evaluated with the aid of detailed analysis...
Final Design and Construction of Gibraltar Dam Strengthening
The results of a 1983 safety evaluation of Gibraltar Dam indicated that the dam did not meet seismic safety standards. A remedial scheme involving the addition of a roller compacted concrete...
Numerical Beach Profile Modelling for Beachfill Projects
The use of beachfill in addressing coastal erosion problems is becoming increasingly popular. It is often more attractive than the conventional structural approaches for economic, aesthetic...
Application of a Beach Plan Evolution Model in Sergipe, Brazil
An offshore breakwater 543 m long located at about 2.4 km from the shore at 10 m of water depth (above chart datums) provides protection to a liquid bulk terminal (Terminal Portuarlo de...
Laupahoehoe Harbor Planning, Design, & Construction
Laupahoehoe Harbor provides access to the fertile fishing grounds along the northeast or Hamakua coast of the island of Hawaii, Hawaii. The planning, design, and construction of Laupahoehoe...
Comparison of Model and Field Results for Barbers Point Harbor
As waves travel into harbors from deep water, nonlinear processes lead to transfers of energy from the wind wave frequencies to long waves with periods of the order of several minutes....
A Dual Approach to Low Frequency Energy Definition in a Small Craft Harbor
Low frequency wave energy in a small craft harbor is examined through comparison between a numerical model and a 3-dimensional physical model. A hybrid element steady state linear monochromatic...
Numerical Modeling of Proposed Kawaihae Harbor, HI
The Kawaihae shallow-draft harbor site is located on the northwest coast of the island of Hawaii, HI. An entrance channel, turning basin, and breakwater currently exist at the harbor site....
Development of Detached Breakwater Design Criteria Using a Shoreline Response Model
An evaluation of beach response to detached breakwaters was conducted using the numerical shoreline response model GENESIS. Functional design parameters such as structure length, gap distance,...
The Application of Technology to Solving Practical Problems
In this paper, the roles of the scientist, technologist, engineer, and manager are discussed to place them in perspective. A distinction is made between the coastal engineer' and practicing...
Our Aging Coastal Infrastructure
The River and Harbor Act of 26 May 1824, signed by President James Monroe, authorized the first involvement of the United States Federal government in the construction of harbor works...
A feasibility study for a Concrete Core Tomographer
This is a study of the feasibility of applying computer tomography in the study of concrete cores. A laboratory protocol is presented for testing concrete cores using a medical - grade...
A Critique of the Ultrasonic Pulse Velocity Method for Testing Concrete
The pulse velocity method is the most widely used ultrasonic nondestructive method for assessing concrete quality. However, it has been well established that the relation between ultrasonic...
