AEG 2021 ANNUAL MEETING
Technical Session #3
GeoUAS (Drones) Symposium Data Acquisition and Processing Methods is the subject of AEG’s 2021 UAS (Unmanned Aerial Systems) Symposium. The use of UAVs (Unmanned Aerial Vehicles, aka Drones) is a rapidly advancing technology that allows for flying of various sensors (photogrammetric cameras, lidar, infrared, etc.) to capture important data sets for projects. The data, typically with survey control is processed by specialized software packages in ordered to produce three-dimensional models for project use (DTM-Digital Terrain Model, DEM4Digital Elevation Model, etc.) These models are very beneficial for project design, construction and monitoring. Various project types will be presented that detail data acquisition and processing methods, all in this half-day symposium of invited Speakers, Wednesday afternoon, September 22, 2021.

THURSDAY, SEPTEMBER 23 – MORNING Technical Session #4
Dams and Levees Symposium – Risk-n-the-River, Part I (Sponsored by Schnabel Engineering) AEG’s Dams Technical Working Group is pleased to host the Dams and Levees Symposium at the 2021 Annual Meeting in San Antonio. The theme of this year’s symposium is “Risk-n-the-River” and will be presented in two parts. This session will lead off with a presentation on the history of Fontana Dam by Scott Walker from the Tennessee Valley Authority. Other speakers represent a combination of federal government agencies and private consultants, and topics include filter compatibility and internal stability, paleoflood analyses, geophysical studies, control of artesian pressures during drilling, block theory applied to scour in a rock spillway, ALARP (as low as reasonably practical) considerations, and lessons learned - sometimes the hard way.
Conveners: Thomas Terry and Holly Nichols Room: Carranza Time
