Comparison of Design Rainfall Criteria for the Southwest
The design of drainage and flood control facilities or the management of floodplains for alluvial fans is extremely sensitive to the design rainfall criteria that is used as input to the...
Flood Hazard Delineation on Alluvial Fans
Alluvial fans are significant geomorphic features of arid lands. The unconfined and dynamic nature of alluvial fans makes standard methods of delineating flood hazards unsuitable. The...
Misapplication of the FEMA Alluvial Fan Model: A Case History
The Federal Emergency Management Agency (FEMA) recently issued revised Flood Insurance Rate Maps (FIRM) for the Tortolita piedmont, located northwest of Tucson, Arizona. Floodplain delineations...
Conjunctive Use of Surface and Groundwater Resources in the Central Valley of California
California Department of Water Resources (DWR) is evaluating the feasibility of incorporating a conjunctive use program into the State Water Project (SWP) to augment its delivery capability...
Prediction of Debris Flow Prone Areas and Damage
It is very important when drawing hazard maps to estimate damage to houses from debris flow of certain fixed quantities. A debris flow disaster, which occurred in Kake Town, Hiroshima...
Design Storms and Sizing of Flood Control Facilities
Design stroms which embody the rainfall characteristics of an area are used for the sizing of drainage facilities. The selection of a design strom may significantly influence the design...
Can Erosion Control Meet Regulatory Standards?
An erosion control design method for rainfall/surface erosion is presented that enables the designer to determine design loads and the resulting erosion control requirements. Design loads...
Municipal Stormwater Management Ordinance Development and Implementation in Pennsylvania
This paper discusses the critical planning and engineering components of a sound stormwater management ordinance and how they can be shaped to avoid commonly encountered basin-wide implementation...
Major Sedimentation Issues and Ongoing Investigations at the Federal Energy Regulatory Commission
There generally exist five types of sedimentation problems. These are watershed, stream, reservoir, estuary and coastal problems. At the Federal Energy Regulatory Commission's...
Decoverly Lake?Functional Hydraulics & Aesthetics
The Decoverly Office Park is located in Rockville, MD. In 1984, engineering design on the seven office building park and pond was begun by the consulting engineers. From the beginning,...
A Tale of Two Laboratories
Two unusual research centers are built with the materials that will be studied in them, but the similarities end there. GE Plastics' $10 million Living Environments concept...
Protection of Wood Designs in Adverse Environments
Engineers and architects are becoming increasingly aware of the risks of poor wood design practices and the benefits of using wood properly. This paper addresses biological factors that...
Repair of an Improperly Detailed Masonry Facade: A Case History
The masonry facade of an 18-story condominium building was constructed with an inconsistent pattern of shelf angle supports, marginal lateral restraints and without any horizontal control...
Building Joint Movement
Moisture leakage in masonry claddings occurs not only through copings and facial separation cracks, but also through failed sealant joints in the veneer. The factors affecting joint movement...
Three Tools for Design Test Bed Analysis
Three analytical tools are outlined for use in design test bed work focusing on the design/production interface. The tools are substitution analysis, coupling analysis, and value chain...
More Than a Public Hearing
Too often, required community input is reduced to the sometimes dreaded public hearing. Many formal public-involvement programs are comprised of no more than this minimal, yet essential,...
Yesterday's Swamp
Since the mid-80s there has been an explosion of engineering firms entering the wetlands design and restoration market. As yesterday's bogs and swamps, once drained and filled...
Prospects for International Engineering Practice
International trade is growing in construction products and services. It is stimulated by international efforts to reduce technical barriers to trade and the formation of a single European...
Commentary on Building Code Requirements for Masonry Structures (ACI 530-88/ ASCE 5-88) and Commentary on Specifications for Masonry Structures (ACI 530.1-88/ ASCE 6-88)
Seismic Surgery
The authors describe the installation of seismic isolators in the columns of an eight-story concrete building in Seal Beach, Calif., which serves as Information Systems Center for Rockwell...
