U.S. Army Corps of Engineers Nashville District
Published Nov. 19, 2024
In response to Hurricane Helene, which struck Eastern Tennessee on September 26, 2024, the U.S. Army Corps of Engineers Nashville District’s Emergency Management (EM) team sprang into action. After the presidential disaster declaration on October 2, 2024, FEMA activated the Nashville District to assist with water and wastewater management and debris removal. The team quickly deployed specialized personnel to assess the hardest-hit areas, ensuring the continuity of essential services and supporting safe debris removal with local National Guard units. Throughout the mission, effective communication, coordination, and logistical support were key to the team's success.

Deep Learning Approach for Accurate Segmentation of Sand Boils in Levee Systems
US Army Engineer Research and Development Center
Published Nov. 19, 2024
Abstract: Sand boils can contribute to the liquefaction of a portion of the levee, leading to levee failure. Accurately detecting and segmenting sand boils is crucial for effectively monitoring and maintaining levee systems. This paper presents SandBoilNet, a fully convolutional neural network with skip connections designed for accurate pixel-level classification or semantic segmentation of sand boils from images in levee systems. In this study, we explore the use of transfer learning for fast training and detecting sand boils through semantic segmentation. By utilizing a pretrained CNN model with ResNet50V2 architecture, our algorithm effectively leverages learned features for precise detection. We hypothesize that controlled feature extraction using a deeper pretrained CNN model can selectively generate the most relevant feature maps adapting to the domain, thereby improving performance. Experimental results demonstrate that SandBoilNet outperforms state-of-the-art semantic segmentation methods in accurately detecting sand boils, achieving a Balanced Accuracy (BA) of 85.52%, Macro F1-score (MaF1) of 73.12%, and an Intersection over Union (IoU) of 57.43% specifically for sand boils. This proposed approach represents a novel and effective solution for accurately detecting and segmenting sand boils from levee images toward automating the monitoring and maintenance of levee infrastructure.
ERDC looks to modernize flood models with levee vegetation index
By
Justin Campfield, ERDC public affairs specialist
U.S. Army Engineer Research and Development Center
Published Nov. 5, 2024
A multidisciplinary ERDC team is working to modernize widely used flood models such as StormSim and Hydrologic Engineering Center software by developing a vegetation index that more comprehensively quantifies vegetation stability on coastal levees. The index will incorporate an array of ecological measurements, such as root/shoot ratios, evapotranspiration rates, soil moisture, vegetation shear, root strength, and vegetation age, size and type.
