Sliplining your way to more flow

Some believe that relining a pipe with a smaller one will decrease its capacity. However, this is not always the case, and often flow capacity can be increased by slipline rehabilitation. More often than not, the minimal diameter decrease is offset by the gains made in flow coefficients. Municipalities striving to repair their aging infrastructure […]

Improving Infrastructure Resilience

Cities will need to overhaul their approach to risk management if they are to make their infrastructure more resilient to catastrophic events, according to a report published by Lloyd’s, the specialist insurance and reinsurance market, and global engineering consulting firm, Arup. The report, Future Cities: Building Infrastructure Resilience, finds that while risk management remains a […]

Sustainable Vegetated Channels

Rip rap is a common channel protection method because of its resistance to most flows with appropriate rock size; however, it does have significant drawbacks. Material can be expensive, not locally available, and placement requires heavy equipment. Rip rap channels are prone to high maintenance, collection of debris and garbage, erosion at boundaries, undermining, and […]

Diversions: CA phase

On Sept. 14, 1996, I was successful in landing the biggest “client” of my life. My best friend, my partner, my wife — Bonnie. On that day in 1996 we entered into a contract (a life contract, if you will) and immediately scheduled the kick-off meeting.

Designing roads to match tomorrow’s weather

By David Hosansky When engineers design roads, bridges, and other types of transportation infrastructure, they need to account for local weather patterns. Extreme heat or freeze-thaw cycles can lead to ruts and cracks in roads, and heavy rains can overwhelm inadequate drainage systems, washing out bridges and flooding key transportation corridors. But how should engineers […]

Liquefaction mitigation

Any engineer familiar with how foundations act in earthquake-prone areas can tell you one thing: Liquefaction — when seismic activity causes soils to act more as a liquid than a solid — can cause serious damage to otherwise safe and sturdy structures. Structural damage to a building is an obvious (and disastrous) result of severe […]

New wastewater treatment approaches

The entire wastewater treatment industry has evolved dramatically during the last 15 to 20 years.
