Estimating Flood Magnitude and Frequency on Streams and Rivers in Connecticut, Based on Data Through Water Year 2015 [open pdf - 6MB]
From the Introduction: "Flooding in Connecticut has caused millions of dollars in damage to towns and cities and has disrupted major transportation systems [...]. Additionally, riverine infrastructure inadequately designed for flood discharges can result in a multitude of problems resulting in danger to human life, extensive loss and damage to public and private property, and damage to the environment (impaired aquatic biota and aquatic habitat). To minimize the damage from floods, protect human health and safety, and conserve wildlife habitat, reliable estimates of the magnitude and frequency of floods are essential. Federal, State, regional, and local agencies rely on accurate estimates of the magnitude and frequency of flood discharges to effectively plan and manage land use and water resources, protect lives and property, and administer flood insurance programs. Flood-frequency statistics compiled from records maintained at streamgages provide a basis for the design of infrastructure, such as roads and bridges; the management of flood risk; the protection of aquatic species; and other engineering and environmental analyses. Flood-frequency statistics can be computed directly for a particular streamgage with a suitable length of record. For short-record streamgages or ungaged sites, regression equations developed from flood-frequency statistics and basin characteristics for a regional group of streamgages can provide estimates of flood-frequency statistics."
