Ricardo Johnson has joined C.H. Fenstermaker & Associates, L.L.C. as Survey & Mapping Director of Coastal Services. A Professional Licensed Surveyor in Louisiana, Alabama, and Arkansas, Mr. Johnson has acquired over 20 years of experience in the coastal regions of Louisiana, primarily through surveying contracts with the Coastal Protection and Restoration Authority of Louisiana. Marc Broussard, Vice President of Survey & Mapping for Fenstermaker, says, “Ricardo brings a tremendous level of experience to our team in the coastal services area. Ricardo’s many years of experience with high accuracy GPS networks, project management and government contracts will, without a doubt, enhance our position in the coastal arena. We’re anxiously looking forward to his leadership and know his level of expertise will dramatically impact our team. His contribution will be instrumental as we enter partnerships with teams requiring our coastal protection and restoration services.” A 39-year veteran in the field of surveying, Mr. Johnson served as Senior Project Manager of Government Services for John Chance Land Surveys, Inc from 1999 to 2016 and then was promoted to Director of Governmental Services. Becoming a Louisiana Registered Professional Land Surveyor in June of 1995, then acquiring professional licenses in Alabama and Arkansas, Mr. Johnson became a member of several organizations including, National Society of Professional Surveyors (NSPS), Arkansas Society of Professional Surveyors (ASPS), Alabama Society of Professional Surveyors, (APLS), and Louisiana Society of Professional Surveyors (LSPS). He was a Chairman of LSPS Elevation Committee from 2013 to 2015. He remains a member of Geomatics Industrial Advisory Committee at Nichols State University in Thibodaux since 2006.

The iLevee project is a state-of-the-art, robust monitoring, warning and response prototype system that can be scaled up to the entire Hurricane and Storm Damage Risk Reduction System (HSDRRS) for the Greater New Orleans area. The state of Louisiana Office of Coastal Protection and Restoration Authority (CPRA) has deployed a series of monitoring stations at strategic locations across the HSDRRS. These monitoring stations comprise a suite of instruments aimed at monitoring the structural health of specific features of the flood protection system. As a prototype for a full-scale rollout data collection at each site is fully automated and real time data are available on iLeveeCentral, a web-based geographic information system (GIS) interface. Levee and floodwall alignments are instrumented in a continuous manner by means of distributed strain and temperature fiber optic sensors that measure areas of strain and temperature change. Other sensors generate data specific to different potential failure mechanisms. In place inclinometers (IPI) and shape accelerometer arrays (SAA) are used to monitor global instability. Tiltmeters and extensometers are used to measure structural deformation of floodwalls. Vibrating wire piezometers measure pore water pressure development in the foundation soils and water levels in drainage canals. Borehole extensometers and GPS stations monitor settlement, heave and ground deformation of the levees and floodwalls. The capabilities of the iLevee system were demonstrated during Hurricane Isaac as it made landfall in southeast coastal Louisiana in late August, 2012. Real time data of the hurricane protection system response was available to emergency response authorities throughout the duration of the storm. Through the iLeveeCentral data management system, additional tidal and river gauges were incorporated as the storm track developed allowing for monitoring of the storm surge advance. A total of 157,000 data points were captured by the system with an average of 930 readings per hour. The early warning system consisted of structural performance indicators and water levels based on established threshold and limit values. More than 100 automatic e-mail notifications were delivered during the peak of the storm to a team of CPRA emergency responders. © (2013) by Association of State Dam Safety Officials All rights reserved.

Human intervention has impaired the Mississippi River's ability to deliver sediment to its delta wetlands, and as a consequence acute land loss in coastal Louisiana has resulted in an unprecedented ecocatastrophe. To mitigate this degradation, an unparalleled restoration effort is underway. For this effort to be successful and sustainable, various sediment input mechanisms must be integrated, including: building appropriate sediment-diversions; beneficially using the millions of cubic metres of sediment dredged annually from navigational channels; harvesting deposits of sand and suitable sediment from the river and offshore; and related sediment management activities that are compatible with other uses of the river. A comprehensive sediment management plan has been developed to identify and delineate potential sediment sources for restoration, and to provide a framework for managing sediment resources wisely, cost effectively, and in a systematic manner. The Louisiana Sediment Management Plan provides regional strategies for improved comprehensive management of Louisiana's limited sediment resources. Copyright © 2014 IAHS Press.
