Application of Computational Model on Berm Breakwater Design
The development of a computational model on dynamic stability is summarized. The model is able to predict profiles of slopes with an arbitrary shape under varying wave conditions. The...
Performance of a Berm Roundhead in the St. George Breakwater System
A new harbor under construction on St. George Island in Alaska's Bering Sea is using the berm breakwater concept for protection from wave attack. Three breakwaters are included...
Berm Type Armor Protection for a Runway Extension at Unalaska, Alaska
A proposed runway extension located on the Aleutian islands was designed to withstand forces of Bering Sea storm generated waves using a unique armor protection concept. The proposed runway...
Unconventional Rubble-Mound Breakwaters?Concerns
A Seminar on Unconventional Rubble-Mound Breakwaters was held in Ottawa, Canada, on the 15th and 16th of September 1987. This paper is an attempt to summarize the general discussion that...
Pipeline Rehabilitation with Polyolefin Pipe
This paper provides an introductory discussion on the rehabilitation of a deteriorated pipe structure by insertion renewal with continuous lengths of polyolefin pipe. This sliplining or...
Arctic Coastal Processes and Slope Protection Design
Cold regions present special challenges for civil engineers. The papers in this book address arctic coastal processes and slope protection design. The first part of the book focuses on...
Evaluation of Infiltration Equations Used in Surface Irrigation
Computer simulations of an irrigation event were conducted using 6 full hydrodynamic models. All 6 models used the same surface flow equations and a different infiltration component. The...
Hydraulic Studies of Surface Drainage from Level Furrows
Field studies have been completed to quantify the surface drainage phenomenon from level furrows which were rapidly flooded and then drained from the inlet end of the furrow. The proportion...
Needed Social, Cultural and Design Changes to Successfully Manage Nigerian Surface Irrigated Projects
The aim of this paper is to illustrate the broad nature of problems associated with the faulty initial designs of water distribution network and irrigation methods and poor participartion...
Surface Water-Groundwater Relations for Open Channels
For losing channels with clean wetted perimeters (no clogging layers), the seepage rate varies essentially linearly with depth to groundwater if the groundwater is relatively shallow,...
1987-88 Actions on El Paso vs. New Mexico
It has been determined by the City of El Paso that water wells near the Texas-New Mexico borders should be used to supplement their water supply in the years 2000-2020. Opposition to the...
A Method for `Warped Surface' Land Forming Design
Most approaches to land forming are based on a plane surface design which in some cases may result in prohibitive costs or excessive removal of top soil....
Simulation of Post-irrigation Moisture Changes for Surface Irrigation of Corn
An attempt has been made to refine prediction of irrigation efficiency obtained at the end of an irrigation by accounting for the losses that occur during redistribution. The water budget...
Drainage Laws and Organizations
The legal issues associated with drainage relate to repelling diffused surface water at the boundaries of one's land as well as with disposing of excess water once it has...
The Role of Social Sciences in the Management of Surface Water Quality in the United States
This survey paper concentrates on what social science has to say about surface water quality management. Some comments are also made on the historical development of these analytical capabilities....
Riprap Design by Modified Safety Factor Method
The Safety Factor method for designing riprap is based upon straight forward physics combining rock properties and flow characteristics. M.A. Stevens developed the method by summing the...
Interfacial Instabilities Associated with Density Currents
Three-dimensional behavior of density currents flowing down a sloping surface has been analytically and experimentally investigated. Attention has been given to the presence of interfacial...
Design and Evaluation of Storm Water Detention Facilities Using a Design Storm and Probable Maximum Storm
When designing a storm water detention facility, both a design storm (DS) and a probable maximum storm (PMS) should be considered. The DS is used to design the facility. The PMS is used...
Overview o New England Coastal Flood Study Methodology
This paper presents an overview of the development of methologies used to determine the probabilistic flood levels for New England coastal flood insurance studies. The Federal Insurance...
Kinematics and Dynamics of Overland Flow
C. Y. Guo combined the kinematic wave approximation with Horton's infiltration formula to analytically solve the propagation of a two-dimensional overland flow on a previous...
