Channel Migration and Avulsion Hazards at Sunshine Point Campground, Mount Rainier National Park, Washington
(2015-03)
In November 2006, the flood of record on the upper Nisqually River destroyed part of Sunshine Point Campground in Mount Rainier National Park, Washington. The Nisqually River migrated north and reoccupied five acres of its floodplain; Tahoma Creek partially avulsed into the west floodplain, topping banks of an undersized ...
Vasa Creek Channel Conditions and Slope Stability, Bellevue, Washington
(2013-12)
The focus of this report is is the channel conditions at Vasa Creek, Bellevue, Washington, with regard to kokanee habitat and slope stability. This required a geomorphic and geologic assessment of the stream and riparian corridor along Vasa Creek.
I focused my efforts in a 720m study-reach just south of I-90 in which City ...
The role of large woody debris and riparian forest in channel avulsion in the Carbon River, Mount Rainier National Park, Washington
(2016-06)
A specific type of natural log jam in the upper alluvial reach of the Carbon River was found to influence secondary channel avulsion, causing flooding hazards to the adjacent Carbon River Road in the northwest quadrant of Mount Rainier National Park, Washington. The fence-like natural log jam was characterized by large woody ...
Geomorphic Impacts of the 2013 Colorado Front Range Flood on Black Canyon Creek and North Fork Big Thompson River
(2016-03)
In September 2013, the Colorado Front Range experienced a five-day storm that brought
record-breaking precipitation to the region. As a consequence, many Front Range streams
experienced flooding, leading to erosion, debris flows, bank failures and channel incision. I
compare the effects that debris flows and flooding ...
Locating the Seattle Fault in Bellevue, WA: Combining geomorphic indicators with borehole data
(2014-12)
The Seattle Fault is an active east-west trending reverse fault zone that intersects both Seattle and Bellevue, two highly populated cities in Washington. Rupture along strands of the fault poses a serious threat to infrastructure and thousands of people in the region. Precise locations of fault strands are still poorly ...
Calling the Cedar River’s Bluff: A study of bed elevation changes and characterizing bluff grain size distributions in the Cedar River upstream of a depositional zone in the City of Renton, Washington
(2019-03)
The Cedar River, a 477 km2 basin draining the Western Cascade Range, has experienced meters of channel aggradation over the last century in the lower three river kilometers (rkm), which has reduced channel conveyance and increased flooding hazards in Renton, Washington. To understand potential drivers of the channel aggradation ...
Assessment of Stream Restoration Efforts and Development of Effectiveness Monitoring Protocol, Ohop Creek, Pierce County, Washington
(2018-06)
Between 2008 and 2015, the Nisqually Indian Tribe, Nisqually Land Trust, and South Puget Sound Salmon Enhancement Group conducted a multiphase restoration project on a two-km section of Ohop Creek, located west of the town of Eatonville, WA. The creek had been channelized in the early part of the 19th century to develop Ohop ...
Effects of Beaver Dam-Break Floods on Downstream Channels in King County, Washington
(2018-06)
Beaver dam failures were responsible for 13 deaths between 1984 and 2003 and can cause damage to infrastructure and property (Butler and Malanson, 2005). In the Puget Lowland of western Washington State, the unique geologic setting with beaver ponds on steep-sided uplands, surrounding flat alluvial plains of rivers like the ...
