Stability of Rock Armour Under Random Wave Attack: Performance of Non-Standard Rock Shapes and Gradings
Quarried rock is frequently used to protect coastal and shoreline structures against wave attack. Armour rock specifications generally exclude rock that is rounded or tabular, and gradings...
The Optimum Gravity Dam
A method is presented for optimizing the cost of a dam by varying the properties of the material and the shape of the dam to produce the lowest cost water barrier to perform the required...
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...
The Construction of New Victoria Dam, Australia
The paper discusses various aspects of the construction of the New Victoria Dam, a 52 m high, high-paste content RCC dam constructed near Perth, Western Australia. The mix design and its...
Design of Miel II?A High RCC Dam
Miel II Dam is a 141 m high RCC structure designed for the tropical mountains of central Columbia. Interesting features are its height (considerably higher than any existing RCC Dam),...
Concrete-Faced RCC Dams
In the past 10 years, roller compacted concrete (RCC) has gained wide acceptance as a cost effective material for constructing and rehabilitating dams. Since the first RCC dams had seepage...
RCC Mixes and Properties Using Poor Quality Materials?Concepcion Dam
This paper discusses aggregate studies, mix investigations, and material property tests for the relatively poor quality materials available for use in RCC at Concepcion Dam....
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...
Hydraulics of Stepped Spillways for RCC Dams and Dam Rehabilitations
Stepped spillways are natural extensions of roller-compacted concrete (RCC) placement techniques. Stepped spillways were first used with concrete dams, and designers are eager to use the...
Design of the Boney Falls RCC Emergency Spillway
The Boney Falls Emergency Spillway was designed as a mass roller compacted concrete structure. Alternative designs considered include a fuse plug, lowering the embankment and paving with...
Coastal Geomorphology and Sand Budgets Applied to Beach Nourishment
It is commonly assumed beach nourishment projects are more successful if applied over long distances of shoreline. Short projects tend to unravel at the ends as the bulge formed by the...
Beach Nourishment with Aragonite and Tuned Structures
The first full-scale use in the United States of imported aragonite sand for beach restoration was undertaken at Fisher Island, Florida, between December 1990 and April 1991. About 20,000...
Monitoring of the 1988 Boca Raton Beach Nourishment Project
During July and August of 1988, approximately 843,000 cm of sand was placed along a 2.3-km stretch of beach in Boca Raton, Florida. Post-cosntruction monitoring of the beach nourishment...
Mitigation of Harbor Caused Shore Erosion with Beach Nourishment Delayed Mitigation, St. Joseph Harbor, MI
St. Joseph Harbor MI. was the first Corps of Engineers Section 111 erosion-mitigation project to be built. Between 1 Jun 76 and 5 Aug 85, about 1,067,000 cy of fine sand was placed in...
Design of Protective Dunes at Dam Neck, Virginia
Dunes act as a primary coastal defense against inundation in the Netherlands and the Dutch Government has devoted considerable effort towards development of reliable procedures for the...
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...
Design, Construction, and Performance of a Baffled Breakwater
The Spud Point Marina breakwater is located within Bodega Harbor, a protected embayment on the northern California coast. Waves are attenuated by baffle panels hung between support piles....
57 Years of Coastal Engineering Practice at a Problem Inlet: Indian River Inlet, Delaware
This paper presents a review of Indian River Inlet's behavior in its natural state prior to jetty construction and summarizes the level of understanding of coastal processes and inlet-bay...
Use of Portable Simulator in Designing Channel Improvements for Port of Brownsville, Texas
The Port of Brownsville, located at the southernmost tip of Texas, serves as an import/export port for both southern Texas and northern Mexico. The proposed channel improvement project...
Dutch Experience on Design of Dikes and Revetments
The increased demand for reliable design methods for protecting structures has resulted in The Netherlands in preparing a set of design guidelines for design of dikes and revetments. The...
