Floodplain Management Course F EMA – Higher Education

1. Floodplain Management Course FEMA – Higher Education Module 1: Floodplain Management -- Bob Freitag, CFM Module 2: Stream Systems on Dynamic Earth – Donald Reichmuth, PhD, PE Module 3: Biological Landscape: The River as Habitat -- Susan Bolton, PhD, PE Module 4: Risks to human settlements – Larry Larson, CFM, PE and Rod Emmer, PhD, CFM Module 5: Policy History (rivers as a legal battleground) -- Elliot Mittler, PhD Module 6: Exercise – Bob Freitag, CFM

2. Module One: Introduction Lenses from which we view floodplains and provide overall management Session 1 Course Introduction Objectives: • Provide an integrated and comprehensive view of Floodplains from four perspectives. • Offer opportunities for applying knowledge to real case studies. • Give practice will the development of management strategies that will result in the least adverse impact. • Enhance the No Adverse Impact (NAI) initiative.

3. Four Functions of a FloodplainThat will be addressed within this course • Receives, holds and transports excess water • Importance Secondary • Acts Sporadically Over Short Periods • Receives, holds, contributes and transports erosional debris • Most Important • Acts Over Long Periods • Receives, holds, contributes and transports chemicals • Receives and manufactures nutrients/energy • Necessary to sustain life • Provides habitat

4. Four dimensions of river ecosystems

5. Module Two Stream Systems on Dynamic Earth Session 2 Effects of Tectonics, Geology & Glaciation on Stream Systems -- The Production of Sediment Session 3 Meteorological Framework -- The Production of Water Session 4 Biologic Framework – The History of Land Use and the Utilization of Resources Session 5 In-Channel & Out-Of-Channel Processes Session 6 River Corridor Management Session 7 Class project (Exercise/evaluation/discussion)

6. Floodplain Definition That portion of a Drainage Basin that is covered by Transported Sediment that was deposited in or near a stream channel. That portion that receives, holds, contributes and transports erosional debris

7. Module ThreeBiological Landscape: The River as Habitat Session 8 Introduction to Ecological Principles and Ecoregions Session 9 Stream and River Ecology Session 10 Water Quality Session 11 The effects of land use/land cover changes on stream ecology Session 12 Management and restoration of river corridors and floodplains Session 13 Perform analysis of the ecosystem of the watershed to determine water needs of living organisms. (Exercise, evaluation, discussion) Session 14 Open Session

8. Floodplain Definition That portion of a river corridor that receives and manufactures nutrients/energy and provides habitat.

11. Definition of a Floodplain A 100 year floodplain is an are along a water course that is normally dry but has a one percent change of becoming wet in any single year. An area that receives, holds and transports excess water

15. Module Six (Exercise/discussion evaluation) • Offer an opportunity to apply knowledge learned from each perspective to a specific problem. • Expand the list of “No Adverse Impact” (NAI) examples.

19. Floodplain definitions • Physical perspective -- “A floodplain is that portion of a drainage basin that is covered by stream transported sediment (Transported Sediment) that was deposited in or near a stream channel.” • Risk perspective -- “A floodplain is an area that is normally dry that has a 1% chance of becoming wet in any given year.” • Biological perspective – “Floodplain is the area adjacent to a river that is periodically covered with water. It is part of the lateral dimension of rivers and contributes to the interchange of materials between terrestrial components and aquatic components of the watershed.” • Policy Perspective: “A floodplain is any land area susceptible to being inundated by waters from any source, and often bears geophysical evidence of previous flood events. The term is sometimes loosely used as an equivalent to the regulated floodplain."
