TRB will conduct a webinar on Wednesday, July 20, 2016 from 2:00PM to 3:30PM ET that features research from National Cooperative Highway Research Program (NCHRP) Synthesis 467: Visualization of Geotechnical Data for Hazard Mitigation and Disaster Response. This webinar will discuss the report, which provides an overview of the visualization tools and techniques used for mitigating geotechnical hazards and responding to geotechnical disasters. The webinar will also provide examples of the technology available to practitioners.rnrnParticipants must register in advance of the webinar, and there is a fee for non-TRB Sponsor or non-TRB Sustaining Affiliate employees. A certificate for 1.5 Professional Development Hours (PDHs) will be provided to attendees who register and attend the webinar as an individual. The webinar presenter is Hollie Ellis with Shannon and Wilson, Inc. and it is moderated by Ty Ortiz, Colorado Department of Transportation.rn [Source: Read more and Register by visiting the Transportation Research Board.

If you've been producing borehole and well logs in traditional ways through desktop database applications, such as gINT and WinLog, or even Excel! we would recommend you try the latest version of ESlog: bore log presentation software.
No installation or credit card are required. ESlog is simple, fast and intuitive web based software for the reporting of boring and well log data with no requirement for desktop software. Data can be manually entered as well as exported from ESdat Environmental Data Management Software.
Our friends at Deep Excavation posted about an interesting micropile case study in Northern Baltimore County for a bridge replacement project. The project consisted of 38 Micro Piles; 7â€ OD X 38 ft. deep including a 7 ft. rock socket, installed on a 3/1 batter, load tested to 272,000 lbs. What caught my attention is the down the hole hammer system used for installing the micropiles. The system uses a ring bit to install the casing and allow the drill string to continue beneath the bedrock elevation to construct the rock sockets.

Maccaferri has a unique research facility, the Maccaferri Innovation Center (MIC), located in Bolzano, Italy. Maccaferri was founded based on their invention of the now ubiquitous gabions, but are now known worldwide as experts in and suppliers of all manner of erosion protection products, geosynthetics, rockfall fences and rockfall meshes, debris flow barriers, and much more. The objectives of the MIC are:
Definition of new products and / or innovative solutions.
Analysis of the implications on material production in their factories.
Analysis of new applications and defining the technical and promotional tools (calculation methods and documentation.
Imagine the scene 4,800 years ago when a rock avalanche nearly 2 km long buried much of the Zion Valley in a matter of 90 seconds, creating a dam on the Virgin River that flooded essentially the entire floor of the canyon that millions of visitors enjoy every year. The researchers that analyzed this event are in the Geohazards group of the University of Utah led by Dr. Jeff Moore. Dr. Moore happens to be an old classmate of mine from the geological engineering program at the University of Arizona. I didn't dig up the publication where this Zion Canyon research was written before it went viral, but there are some great figures posted on his website and I'm sure you can click around and find the citation if you are interested.

The Swiss and many other European dignitaries celebrated the opening of the World's longest and deepest tunnel last week, the Gotthard Base Tunnel, after 17 years of construction. The tunnel beneath the Swiss Alps is 57-kilometers long (35-miles long) reaching a depth of 2,300 meters (7,545 feet, almost 1.5 miles). The tunnel will create a high-speed rail link between northern and southern Europe. Trains will travel the tunnel, which runs between the towns of Erstfeld in the north and Bodio in the south, in only 20 minutes, reaching speeds of up to 250 kilometers an hour (155 mph), according to CNN.

GeoPrac sponsor Nicholson Construction has started a chemical grouting project in Los Angeles at the Woodrow Wilson Classical High School to treat potentially liquefiable soils beneath the building. This $2 million project is part of a larger $21.1 million project to upgrade the infrastructure in the auditorium and adjacent areas. Nicholson will drill vertical, horizontal and inclined holes at depths of 14 to 24 feet beneath the structure and inject the chemical grout using a Tube-a-Manchette piping system.
