SEDIMENT DATA- COLLECTION TECHNIQUES March 24-28, 2014 Castle Rock & Vancouver, WA U.S. Geological Survey Training Course SW1091 Elvis Lives! Course Coordinator Gary P. Johnson, USGS, Urbana, IL (gjohnson@usgs.gov)
Welcome!!!! • Looking forward to a great week, it will go fast! • Hoping you enjoy taking the class as much as we enjoy teaching it!! • This is a special week for at least 3 reasons… • Introductions
Beginning of the week • End of the week
Agenda Overview • Parker’s Conf. Cntr. mornings, field afternoons • Parker’s for evening sessions M-W* • “Captive audience”, but lots to gain! • Cowlitz River/Castle Rock bridge M-Tu • A river draining Mt. St. Helens, wading W • “Up the Mountain” on Th aft • Pizza party @ HoffstadtTh eve • CVO Sediment Lab + Data lecture Fri • Friday depart Castle Rock @ 0655 SHARP! • Friday depart CVO for PDX by 1130 * Includes hors d’oeuvres and libations; be there or be square
Mt. St. Helens Motel • Restaurants a walk SW and NW of hotel • QuickMart a 200-yard walk west (don’t buy the chicken, it’s always 8-hours-old & dry…) • Grocery market in Castle Rock (~2 miles) • Microbrew shop between there and motel • Damn, what more could your want?
Inventory • Name tags (wear them please!) • Notebooks, pencils • Various USGS propaganda • Rulers, sediment size gradiometers • Website: http://kleene.er.usgs.gov/sdct/Sediment_Data_Collection_Techniques • Most comprehensive resources of USGS ++ sediment info • Lectures • Reports, technical memoranda, forms • Instructor bio and related info
Inventory • PFD’s and vest (bridge work) • PFD, waders/hip boots (wading) • Rain gear/gloves • Rulers on Wednesday (Wed.) • Field Notes/pencils/clip boards
Field Work • Safety First! No shortcuts… • PDF’s at all times when in, over, or near a river; also vests on bridge(s) • Prompt departures for field important • Divvy up class into ~6 groups for all field work • 6 stations • WHITE BOARD
Overarching Objectives of Course To impart a sufficient understanding of fluvial sediment data-collection techniques to be able to: • collect quality-assured samples for use in computing sediment-discharge records and metadata for storage in the USGS National Water Info System. • design a sediment data-collection program for review by an experienced sedimentologist, and
Scope of course Instruction and field practice of USGS methods for the safe collection of quality-assured fluvial-sediment data: suspended sediment bedload bed material You will hear these and other terms multiple times this week
Scope of course (cont) As underpinnings for this we provide instruction on: • Basic fluvial-sediment concepts • Sediment-sampling equipment & deployment • Quality-assurance techniques • Computational methods • Sediment-surrogate technologies • Network design • Sediment-lab instruments and techniques • Database considerations (SedLOGIN application)
Upon Departure, Students Should: • Understand basic fluvial-sediment concepts • Understand and appreciate the value of a representative sample • Be familiar with more common tools for collecting sediment data, and their limitations • Be able to safely collect representative • suspended-sediment samples isokinetically • bottom-material samples • bedload samples • Develop a sediment-monitoring program plan for review/approval by an experience sedimentologist
Sampling of Questions to Ponder… • Different instructors may have different opinions– and that’s ok!! Discuss!! • Can I deviate from the standard protocols that are the focus of this class? If so, when and under what conditions? • Can I use samplers developed outside of the Federal Interagency Sed. Project? • But perhaps most importantly…..
HELP! Know who to contact for: • Assistance • Advice • Guidance
Course Critique, etc. • Form provided at end of week • Must be submitted to receive course-completion certificate • Very Important to receive feedback -- please be forthright, pull no punches • Form is anonymous • Problems? See any instructor • Take advantage of access to instructors. We want to meet/talk shop with each student.
This is your course – make the most of it! • Provide feedback • Open season at day’s end; sound off…
Fluvial-Sediment Data Needs in the U.S. • Historical: Maintenance of reservoirs, channels, and hydraulic structures/bridge piers • Today’s needs include but are not limited to: - Legal requirements – TMDL’s - Contaminated sediment management - Best Management Practice (BMP) Evaluations - Fire-burn hydrology/sedimentology - Stream restoration/geomorphic assessments - Physical-biotic interactions - Global carbon budget - Sand budget and bar maintenance - Productivity of agricultural lands - Dam decommissioning, rehabilitation, removal
* • Built in 1909 for hydropower • Head = 7 Meters • Abandoned for power generation in 1960’s • Blocked American shad and striped bass from reaching historic spawning grounds • Environmental benefits of dam removal justified demolition by Federal Government

Sediment Damages are Costly • Physical, Chemical, and Biological Sediment Damages in North America Total >$25-$65 Billion*Annually (Most in the USA; AGU-EOS, 10/5/2004; Science, V.267, pp. 1117-11123; adjusted for inflation to 2010; Osterkamp et al. 1998) • Given a 1% Reduction in Damages Through Better Resource Manage, a Continental Sediment Monitoring Program WouldPay for Itself at least 40 TimesOver
