By: Roger Chung, PE In the August luncheon, Dr. Dragi Stefanovic of Tetra Tech, Inc., presented a new procedure for hydraulic analysis and floodplain mapping of “Without Levee” (Natural Valley) conditions in accordance with latest FEMA guidelines for Analysis and Mapping of Non-Accredited Levee Systems. An unsteady hydraulic model (HEC-RAS) is developed to analyze flows in the main river, while two-dimensional flood routing (HEC-RAS 2-D) is utilized for the floodplain mapping on the landward side of a levee. The advantages and challenges of the new approach are discussed with special emphasis on the long awaited HEC-RAS Version 5.0 featuring a two-dimensional modeling component.
Read MoreCivil engineers reimagine the world and shape the future of our civilizations. Recent conversations with several Orange County Branch members reminded me of the inspiring initiative led by ASCE, known as Future World Vision. The effects of climate change, increasing population, and rapid deployment of new technologies drive civil engineers and the infrastructure industry to be at the forefront of changing trends and to constantly adapt. ASCE performed an in-depth analysis of future macrotrends to generate a projected evolution of our industry's infrastructure through the Year 2070.
Read MoreMy friend, Sam Ali, P.E., recently wrote a story on bike trail connectivity in Orange County. The article was published in the ASCE Civil Engineering Magazine. Since Sam and I share the same passion for cycling, I thought I would seize the opportunity to share a few enjoyable rides in our OC backyard.
Read MoreWe have all been witnessing price inflation, whether it is at the gas station or at the grocery store. Both inflation and material shortage have become part of our design considerations when we select and specify materials for our projects. The approach has been further emphasized over the last couple of years: the Architectural Engineering and Construction (AEC) community should initiate design and construction projects with a thorough understanding of material availability, fabrication, delivery lead time, projected construction index price, and an evaluation of equivalent alternatives.
Read MoreOur 2nd Annual Women in Construction Week was a huge success! On behalf of the Orange County Construction Institute, we would like to thank everyone who made this hybrid week of events possible. Thank you to our amazing sponsors: SKANSKA, Turner Construction, LINXS, ASCE Los Angeles Section, Port of Long Beach Construction Management Division, Ardurra, and Steiner Consulting Inc.
Read MoreLast month, I traveled to Chile for my brother’s wedding and took the opportunity to wander in Patagonia, the Colchagua Valley (wine country), Santiago, and a few other places. I don’t know if the pattern is common across my peers, but as for myself, travels are generally punctuated by a constant evaluation of the local infrastructure, design details, construction means and methods, and an assessment of the infrastructure challenges that each region faces.
