Engineered Log Jam (ELJ) Influence on Flows and Bed Morphology in the South Fork Nooksack River

When: Thursday, June 21, 12:00pm - 1:00pm
Where: Brown & Caldwell Seattle Office, One Convention Place, 701 Pike Street, Suite 1200, (206) 624-0100

Speaker: Joanna Crowe Curran, Herrera Environmental Consultants/Indicator Engineering
Abstract
This study is funded by the University of Brighton to improve planning for river and habitat restoration projects that involve Engineered Log Jams (ELJs). Overall project goals are to: quantify the effect of ELJs on channel bed topography and flow complexity using a combination of field measurements and experimental modelling; quantify the effect of ELJs on sediment flux; correlate the abiotic measurements with biotic data on fish use; use the results to inform habitat suitability assessments; and determine the potential effectiveness of ELJs as a management tool to reduce flood risk and increase aquatic habitat diversity. ELJs have been employed on the Nooksack River to direct flow into side and chute channels with the larger goals of increasing overall channel complexity and salmon spawning opportunities. Fieldwork is focused on the South Fork Nooksack River between Acme and Saxon (to include the Hutchinson and Nesset project sites). The sites were visited in July, 2017 and May, 2018 to capture the interaction between flow and ELJ at low and high discharge rates. We used a M9 Acoustic Doppler Current Profiler (ADCP) to measure channel bathymetric and three-dimensional flow velocities. Exposed gravel bars and ELJs were measured with a Terrestrial Laser Scanner (TLS) in July and through the combination of drone data collection with structure-from-motion in May. This talk will focus on the results of the flow and bed monitoring, particularly the relative footprints of different ELJ types, sizes, and locations on flow velocities and bed elevation.

Speaker Bio
Joanna Crowe Curran is a geomorphic engineer in Seattle. She works with Herrera Environmental Consultants, Indicator Engineering, and on independent research projects. Dr. Curran’s work focuses on channel hydraulics and sediment issues as they pertain to aquatic habitat, water quality, reservoirs, and impacts to bridges and river adjacent infrastructure. Her experience with river and watershed restoration strategies have included in-channel LWD structures, dam removal, in-stream flows, and reducing the impacts of urban stormwater through implementation of low impact development BMPs. She is co-developer of the nationally used Wilcock and Crowe mixed sediment transport model, and can develop and analyze empirical, analytical, and numerical modeling using an array of 1D, 2D, steady, and unsteady modeling platforms. Dr. Curran has a MS in Geological Sciences from The University of Texas at Austin and BS and PhD in Environmental Engineering from Johns Hopkins University.

YMF Happy Hour & Mariner's Game RSVP

When: Tuesday, July 3
Happy Hour at Pyramid Brewery Beer Garden, 5:30pm - 7:00pm, Mariners at Safeco Field, 7:10pm

Catch up with your fellow engineers and get an early start on the 4th of July Holiday with some happy hour and a Mariners game (with a fireworks show at the end!). If you're not interested in going to the game, feel free to just join us for some beverages and snacks in the sun before the game.

Contact Leo Moyer by June 22nd to get your tickets with the group. Tickets are expected to cost about $25 per person.

YMF Spring Co-Ed Volleyball

When: April-June 2018
Where: Ingraham High School, 1819 N 135th St, Seattle, WA 98133
Volleyball anyone? ASCE YMF is looking to recruit a couple new players to continue our winter season team for the spring. If you're interested, please fill out the very short survey: Volleyball Survey.
All games are played on Sunday afternoons and all skill levels are welcome! We will contact respondents towards the end of March to let them know if we are putting a team together.
If you have any questions please email Leo Moyer.

ASCE Legislative Committee - Volunteers Needed

Volunteer Needs

ASCE Seattle Section is searching for volunteers to assist with the Legislative Affairs Committee. The level of Involvement can vary and and can include providing engineering judgement on current legislative issues to assisting with lobbying.

The new Committee Chairperson is Savannah Linders and the new State Advocacy Captain is Dr. Conrad Felice.

Below is a description of the work that the Legislative Committee participates in.

The Legislative Committee functions in the political arena. The committee can become active in federal, state, county or other governmental issues that are of interest to the profession (such as university engineering budget considerations, issues that affect the practice of or employment of civil engineers, and environmental issues of significance to the profession). The committee is responsible for disseminating information from the AELC pertaining to state legislation. In recent years, the chair of the Legislative Committee has also been the AELC representative. If they are different, the Legislative Committee chair is an alternate to the AELC and shall be responsible for keeping abreast of current activities of the AELC.

The committee reviews proposed legislation and comments on it with regards to its effect on the civil engineering profession. The committee may request the Board take an official stance on certain legislation that is being proposed as appropriate. The committee and its members may also be called upon to testify at Legislative hearings or for other governmental committees (it must be noted that if such testimony is not previously approved by the Board or general membership, such testimony cannot represent the official position of the Seattle Section and is as an individual). The committee should work toward establishing a key contact group of members of the Society who have contacts with elected officials and who would be available to communicate the position of the Section. The committee is generally active prior to and during the sessions of the state legislature. The committee at times seeks the advice of other Section committees that may be more versed on a particular legislation topic. The committee typically sends at least one representative to the Society's annual Legislative Fly-In in Washington D.C.
