January Meeting Annoucement

DATE:    Wednesday, January 31st
PLACE:  Hawthorne Lucky Lab Brew Pub, 915 SE Hawthorne Blvd
TIME:     11:30 a.m. Networking, 12:00 – 1:00 p.m.
TOPIC: The Urban Beaver Study: An Examination of the Effects of Beavers on an Urban Streamscape
SPEAKER: Erin Poor, USGS


Agencies are seeking alternative ways of restoring and enhancing resilience in urban stream networks within the constraints of existing infrastructure. One potential strategy may be to support beaver recolonization of urban streams. Beaver dam building activity has been found to attenuate streamflow and provide ecological uplift in areas that have experienced minimal human impact. But does this hold true in urban streamscapes? The urban beaver study seeks to answer this question and provide resource managers with science that will inform strategic management and planning decisions.

Erin is an avid outdoorswoman who has been hiking trails in the Pacific Northwest since she was just six-weeks old. Hiking may be an exaggeration as her parents did most of the work back then, but nonetheless her passion for nature and curiosity about stream systems was sparked at a young age. Erin currently works as a hydrologist with the U.S. Geological Survey, Oregon Water Science Center. As a member of the water quality team Erin examines issues facing urban streams.

October Meeting Annoucement

DATE:    Thursday, October 19th
PLACE:  Hawthorne Lucky Lab Brew Pub, 915 SE Hawthorne Blvd
TIME:     11:30 a.m. Networking, 12:00 – 1:00 p.m.
TOPIC: Dairy Creek – Reconnecting to Restore Habitat Functionality
SPEAKER: Jason Magalen, Solmar Hydro, Inc.


Sturgeon Lake is located within the boundaries of Sauvie Island. Historically, circulation of the lake was maintained via, primarily, the Gilbert River (connected to the Multnomah Channel) to the north and Dairy Creek (connected to the Columbia River) to the south. Recent hydraulic changes have caused sediment infilling within Sturgeon Lake, decreasing water quality and degrading habitat. One of the selected methods to restoring lake function was to re-connect Dairy Creek between the Columbia River and Sturgeon Lake. This presentation will focus on the coordination requirements for the many stakeholders, and the ensuing 1D/2D hydraulic modeling, analysis, and engineering methods employed toward final design.

Mr. Magalen is a Coastal Engineer and Hydrographer with Solmar Hydro, Inc. in Portland, OR. He has 15 years of experience in hydrographic and marine geophysical surveying; and coastal, dredge, marine, and environmental engineering. The majority of his career has focused on hydrographic/geophysical and topographic surveying; hydrodynamic, sediment and water quality marine data collection, analysis and numerical modeling; coastal, estuarine, and riverine modeling; and evaluation and design of coastal structures. Type of projects have included contaminated and non-contaminated sediment erosion and transport assessments; wave and current studies; bridge scour evaluations; fish passage and wetland restoration projects; marine hydrokinetic (offshore wind and wave energy generation) studies; dredging project design; shoreline revetment and breakwater design; and construction management. He has worked for both the private engineering and consulting sector as well as the public (with the U.S. Army Corps of Engineers in Portland).

He holds a Bachelor of Science Degree in Civil Engineering from The Ohio State University, and a Master of Ocean Engineering Degree from Oregon State University. He is a registered professional engineer in CA, OR, WA, and Guam; is a NSPS/THSOA Certified Hydrographer; and is a certified Remote Pilot in Command (FAA Part 107). He is a past president of the Oregon Section of the American Society of Civil Engineers (OR ASCE) and is presently active with the NSPS/THSOA Exam Certification Board.

May Meeting Annoucement

DATE:    Wednesday, May 31st, 2017
PLACE:  Hawthorne Lucky Lab Brew Pub, 915 SE Hawthorne Blvd
TIME:     11:30 a.m. Networking, 12:00 – 1:00 p.m.
TOPIC: Drone LiDAR Data Acquisition
SPEAKER: Kevin Darrow, BD Aerial


More and more organizations are turning to unmanned aerial systems (UAS) solutions for water restoration projects. BD Aerial, a Portland-based drone services company specializing in LiDAR data acquisition, will dive into 2 examples of how organizations have used UAS to help solve environmental challenges.

Use-Case #1: What’s the best way to survey a working spillway without halting the operation and without putting personnel at risk?

Use-Case #2: In an effort to restore a fish habitat, (orga
nization) needed to remove water control structures, which would flood low-lying property. It was necessary to use a sensor capable of vegetation penetration to understand the topography of the project area and assemble the appropriate restoration plans.


Portland, Oregon drone services company, BD Aerial, was established in 2012 and is a leader in using UAS to safely inspect and document land and industrial assets. BD Aerial started in the Pacific Northwest and quickly became a preferred UAS service provider across the Nation; Now operating Worldwide with companies like Discovery Channel and National Geographic.

BD Aerial flies payloads including precision LiDAR systems, UV and Infrared sensors, and high-resolution cameras for photos, videos and photogrammetry. Using unmanned aircrafts, they capture actionable data for surveying high-risk landslide areas and terrain, maintenance inspections, engineering documentation, and construction mapping.


Kevin Darrow is Head of Business Development at BD Aerial. His role includes the company’s overall marketing strategy, project management, and strategic partnerships. In an industry that changes daily, he’s excited about exploring new UAS applications to help clients find creative solutions to their problems.
