Measurements in the York River

Image
On July 10-11, our summer 2018 field team (Dennis, Matthew, Julie and Nina) completed geotechnical measurements and sediment sampling in the Pamunkey River and in the York River in collaboration with Grace Massey, Carl Friedrichs and team from the Virginia Institute for Marine Sciences. The measurements represent the first field component of a project developing an advanced method to utilize portable free fall penetrometers for unexploded site investigation, monitoring and management funded by SERDP (https://www.serdp-estcp.org/).

CPT'18

Nina, Bilal and Cagdas attended the CPT'18 conference in Delft. They contributed to three presentations of papers. All papers are available at http://www.cpt18.org/program/proceedings/.

Congratulations to Dr. Bilici

Image
Big shout-out and congratulations to Dr. Cagdas Bilici who defended his PhD thesis titled "Development of a sediment sampling free fall penetrometer add-on unit for geotechnical characterization of mobile seabed surface layers" successfully. Cagdas started his PhD with Nina as his advisor in January 2015, and has first-authored and contributed to multiple journal and conference papers.

Field experiment in Duck, NC

Despite some initially rough weather, we were able to complete another survey in Duck, NC. This time our investigations aimed for variations in moisture contents and beach slope, and how this is reflected in satellite imagery and ground-based radar. This work is in collaboration with Dr. Jesse McNinch and Dr. Heidi Wadman from the USACE FRF in Duck, NC, and is supported by the Office of Naval Research.










Congratulations to Dr. Ali Albatal

Big shout-out and congratulations to Dr. Ali Albatal who defended his PhD thesis titled "Advancement of using portable free fall penetrometers for geotechnical site characterization of energetic sandy nearshore areas" successfully. Ali started his PhD with Nina as his advisor in January 2015, and has first-authored and contributed to multiple journal and conference papers.

New project: Integrated Geotechnical and Geophysical Field Data Collection to Investigate Scour and Post-event Infilling at Subaqueous Foundations, Levees and River Banks impacted by Hurricane Harvey

Image
We just started a new project funded through NSF's RAPID program: "Integrated Geotechnical and Geophysical Field Data Collection to Investigate Scour and Post-event Infilling at Subaqueous Foundations, Levees and River Banks impacted by Hurricane Harvey". The project is based on the observations during Nina's GEER reconnaissance mission in September in Texas.

In this new project, Nina, Co-PIs Navid Jafari (LSU) and Nadarajah Ravichandran (Clemson), and collaborators Jean-Louis Briaud and Iman Shafii (Texas A&M) will investigate more scour and scour infilling using a suite of geotechnical and geophysical methods. Stay tuned for results.

Starting new project to assist UXO site management

Image
We are starting a new exciting project titled "Improved Penetrometer Performance in Stratified Sediment for Cost-Effective Characterization, Monitoring and Management of Submerged Munitions Sites". We are hoping to improve portable free fall penetrometer data analysis to assist with the management and characterization of submerged munition sites.
The project is funded by SERPD (https://www.serdp-estcp.org/), and the project will be in collaboration with VIMS (http://www.vims.edu/). The project will start on 01 May 2018. Stay tuned for first field work results in late summer.
