Description: Tens of millions of dollars are spent every year on emergency flood and bank protection measures throughout the Western United States to protect critical infrastructure and property, such as roads, pipelines, levees, and residences. Due to their inherent urgency, emergency situations tend to be exempt from environmental regulations and lack the science and engineering that goes into non-emergency projects. Rapid response tends to lead to relatively crude applications of shoreline protection such as end dumping rip rap that may later require mitigation. Individual emergency response actions are typically limited in geographic extent with minimal environmental impacts. But cumulatively, year after year, emergency responses can have significant impacts and transform relatively pristine rivers into armored ditches. This course provides tools for assessing the magnitude and extent of flood emergencies, and provides a number of environmentally sensitive rapid response protection measures that integrate into long term solutions.

Field Trip (all day Thursday)*

Conclusions

*A one day field trip will be taken to look at several different types of emergency situations, responses, and cumulative impacts and potential cumulative benefits of different response strategies.

Intended Audience: This hands on course is intended for engineers, biologists, and ecologists seeking an improved understanding of emergency flood hazard assessment. Prerequisites: A basic understanding of fluvial geomorphic processes is required.Course Materials: Each participant will receive a copy of the course proceedings and reference material. Drinks and snacks will be provided each day. Lunch will be provided during the field trip. Participants will be on their own for lunch the other two days.
