severe streambank erosion requires mitigation efforts<\/strong><\/h2>\n

meandering through central iowa, ioway creek, formally known as squaw creek, is a 42-mile-long tributary that empties into the south skunk river on the southeast side of ames. due to the waterway\u2019s steep banks, highly erodible soils, and volatile flooding events, significant streambank erosion had occurred over many years. the erosion had progressed to the point that it threatened the stability of a 24-inch water main<\/a> running under the creek near the lincoln way bridge.<\/p>\n

this pipeline transports potable water to serve approximately 18,000 residents in the area along with the entire region containing iowa state university. previous attempts to control the erosion<\/a> issue in this highly flood-prone region were unsuccessful, prompting the ames city leaders<\/a> to seek a sustainable, long-term solution. snyder & associates was contracted to recommend engineering techniques that could stabilize the creek banks, in turn protecting the existing water main.<\/p>\n

throughout the analysis and 2022世界杯32强预选赛 phase, the project evolved into a more extensive undertaking, addressing safety concerns regarding a low-head dam located in the area. the dam created circular currents that compounded the streambank erosion, impeded fish passage, and posed a drowning hazard. this adjustment was proved necessary as two kayakers narrowly survived a life-threatening situation after being sucked into the dam\u2019s undertow. occurring just before the project\u2019s completion, this timely incident drew further attention to the safety hazards posed by low-head dams.<\/p>\n

working with the federal emergency management agency (fema) for over six years, hazard mitigation grant program (hmgp) funding was secured to finance the streambank stabilization<\/a> project and mitigate the threat posed by the dam. the many streambank stabilization efforts our team incorporated involved:<\/p>\n
