Erosion Control—Its Impacts, Technology, When It Goes Right, When It Goes Wrong
International Erosion Control Association The International Erosion Control Association (IECA) is the world’s oldest and largest association devoted to solving problems caused by erosion and its byproduct—sediment. IECA’s 3,000 members specialize in stormwater management and natural resource protection. Each year the IECA holds its annual conference. The 2010 gathering, IECA’s 41st Conference and Expo in Dallas, presented its 13th Annual Photo Contest of erosion control projects. The contest categories were: Impacts of Erosion & Sediment Control Technology in Action Erosion Control Bloopers Before and After There were awards in each category for 1st, 2nd and 3rd place photos, along with other photos of projects recognized but not awarded. Here we present, with the kind courtesy of the IECA, the 1st, 2nd and 3rd place awardees in each category.
