TOPIC: Is the Dead Sea Dead?

scott wells 2

The Dead Sea is a terminal lake and is the lowest water body on the earth’s surface. As a result of historic changes in inflows to the Dead Sea, water levels are now receding at more than 1 m per year. There have been many proposed solutions to the ‘dying’ Dead Sea such as reinvigorating the Jordan River by bringing in desalinated water from the Mediterranean Sea and pumping sea water from the Gulf of Aquaba. Water quality impacts on the Dead Sea were evaluated for the latter solution by constructing a suite of mathematical models of the circulation and chemistry in the Dead Sea. Will these proposed ‘solutions’ save the Dead Sea?

Bio: Scott Wells, Professor Department of Civil & Environmental Engineering Portland State University

He has a Ph.D. from Cornell University in Civil and Environmental Engineering, and graduate and undergraduate degrees from MIT and Tennessee Technological University. His current research focus is environmental fluid mechanics: modeling of surface water quality and hydrodynamics and solid-liquid separation processes. He has written over 100 technical publications.

He has been involved in well-over 100 water body studies throughout the United States in Oregon, Hawaii, Virginia, Tennessee, Kentucky, Idaho, California, Oklahoma, Texas, Washington, Wisconsin, North Carolina, Oklahoma, Montana, New York, Colorado, and Florida. He has also been involved in projects in Canada, Guyana, Peru, Brazil, China, Ukraine and Israel/Jordan. He has received 2 Fulbright scholar awards, one to the Ukraine working on the Dnieper River and the other to Israel where he is continuing to work on a computer simulation model of the Dead Sea.

He is a co-author of the water quality and hydrodynamic model, CE-QUAL-W2, used throughout the world for hydrodynamic and water quality modeling studies. He has been actively involved in studies for local, state and federal government as they work on improving water quality in surface water systems and in understanding the environmental impacts of reservoirs and how to manage water quality in surface water systems.

EWRG March Meeting Announcement

DATE:    Wednesday, March 30th, 2016
PLACE:  Hawthorne Lucky Lab Brew Pub, 915 SE Hawthorne Blvd
TIME:     11:30 a.m. Networking, 12:00 – 1:00 p.m. Presentation
SPEAKER:  Amber Clayton
TOPIC: Portland’s 2016 Stormwater Management Manual

smmm pdx 2016This presentation will discuss the goals of the proposed 2016 revisions to the City’s SWMM, key highlights to look forward to, and a summary of the public comment and adoption process. A draft proposed SWMM will be released for public comment in April. The public comment period for proposed changes will be April 4th through May 2nd. Highlights of the 2016 SWMM revisions include:

  • – System-specific stormwater requirements that reinforce the existing stormwater infiltration and discharge hierarchy
  • – A new Presumptive Approach Calculator interface
  • – Updated stormwater facility design criteria and typical details
  • – Separate Source Controls (previously Chapter 4) into its own administrative rule

Amber Clayton is the City of Portland Environmental Services Stormwater Management Manual Program Manager.  She has 15 years’ experience in stormwater and watershed management, including public-private partnerships, stormwater facility design and construction, and stormwater-related regulatory policy.  She is currently leading the Bureau’s effort to update the Stormwater Management Manual.

EWRG February Meeting Announcement

DATE:    Wednesday, February 24th, 2016
PLACE:  Hawthorne Lucky Lab Brew Pub, 915 SE Hawthorne Blvd
TIME:     11:30 a.m. Networking, 12:00 – 1:00 p.m. Presentation
SPEAKER:  Matt Koozer, Pete Munoz and Jared Kinnear
TOPIC: From Concrete to Carex: A Green Approach to Wastewater Treatment

 Wastewater treatment using Natural Treatment Systems (NTS), where wastewater is treated or polished in wetlands, is becoming more common.  NTS projects can be a cost effective method of cooling and removing nutrients from wastewater prior to discharge to receiving streams while also providing complex wildlife habitat, community recreation, and environmental educational opportunities.

Clean Water Services, (CWS) a wastewater and stormwater utility in Washington County, Oregon developed a 90-acre NTS project at its Forest Grove Wastewater Treatment Facility in 2014.  Fernhill Wetlands has been identified by the Portland Audubon Society as one of the top 10 destinations to bird watch in Oregon.

This presentation will focus on CWS’ decision-making process that led to the selection of using NTS at the Fernhill site, initial project goals, engineering design, construction delivery, revegetation, and on-going monitoring and research.

Matt Koozer, Biohabitats, Senior Restoration Ecologist and Construction Manager –  Matt Koozer has 17 years’ experience leading interdisciplinary design-build teams in water resources management and habitat restoration eff orts in the Pacific Northwest and Montana. He has managed all phases of river, estuary, wetland and riparian restoration and management projects. Matt has focused the bulk of his career on habitat restoration design and construction. Mr. Koozer has been involved in over 100 habitat restoration projects including dam removal, channel realignment, estuary levee breaching and set back levee construction, engineered log jams and riffles, and fish passage projects including culvert replacements and water intake diversion and fish screening modifications.  On the Fernhill Project, Matt assisted the design team, provided construction cost opinions and constructability review, wetland seed and plant selection assistance, plans and specifications coordination, large woody debris design, and construction oversight.

Jared Kinnear, Clean Water Services, Recycled Water Program Manager – Jared is the Recycled Water Program Manager at Clean Water Services.  He is a Professional Wetland Scientist and has worked on design, permitting, and implementation of wetland mitigation and stream enhancement projects throughout the Pacific Northwest over the past 15 years.  For the Fern Hill Wetlands project, Jared was responsible for construction oversight, wetland plant selection, and operations and maintenance once the NTS is functioning.

Pete Muñoz, PE, Biohabitats, Cascadia Bioregion Team Lead – Pete A. Muñoz is a seasoned engineer who has focused the bulk of his career on the development of sustainable water infrastructure. A licensed engineer and certified wastewater treatment plant operator, Mr. Muñoz has been involved in over 200 infrastructure projects including wastewater treatment, stormwater management, rain harvesting, environmental remediation, and watershed restoration. He maintains a holistic perspective when examining and addressing water related questions. Mr. Muñoz has been asked to speak around the country on a variety of topics including green infrastructure, constructed wetlands, and climate change solutions. Mr. Muñoz is a partner in the Alliance for Regeneration, EcoDistricts Incubator faculty, and he teaches several courses at Yestermorrow Design-Build in Warren, Vermont and the Omega Institute in Rhinebeck, New York.  Pete led the assessment, modeling, and design of the Fernhill project.
