Applying geomorphological principles and engineering science to develop a phased sediment management plan for Mount St Helens, Washington

ABSTRACT: Thirty-seven years post-eruption, erosion of the debris avalanche at Mount St Helens continues to supply sediment to the Toutle – Cowlitz River system in quantities that have the potential to lower the Level of Protection (LoP) against flooding unaccept- ably, making this one of the most protracted gravel-bed river disasters to date. The Portland District, US Army Corps of Engineers (USACE) recently revised its long-term plan for sediment management (originally published in 1985), in order to maintain the LoP above the Congressionally-authorized level, while reducing impacts on fish currently listed under the Endangered Species Act, and minimizing the overall cost of managing sediment derived from erosion at Mount St Helens. In revising the plan, the USACE drew on evidence gained from sediment monitoring, modelling and uncertainty analysis, coupled with assessment of future LoP trends un- der a baseline scenario (continuation of the 1985 sediment management strategy) and feasible alternatives. They applied geomorpho- logical principles and used engineering science to develop a phased Sediment Management Plan that allows for uncertainty concerning future sediment yields by implementing sediment management actions only as, and when, necessary. The phased plan makes best use of the potential to enhance the sediment trap efficiency and storage capacity of the existing Sediment Retention Struc- ture (SRS) by incrementally raising its spillway and using novel hydraulic structures to build islands in the North Fork Toutle River (NFTR) and steepen the gradient of the sediment plain upstream of the structure. Dredging is held in reserve, to be performed only when necessary to react to unexpectedly high sedimentation events or when the utility of other measures has been expended. The engineering-geomorphic principles and many of the measures in the phased Sediment Management Plan are transferrable to other gravel-bed river disasters. The overriding message is that monitoring and adaptive management are crucial components of long- term sediment-disaster management, especially in volcanic landscapes where future sediment yields are characterized by uncertainty and natural variability. © 2017 The Authors.

Two sites in Washington were located at Mount St. Helens, a volcano in the Cascades, ca. 100 km northeast of Portland, OR. In May 1980, Mount St. Helens erupted with catastrophic effects. Large tracts of vegetation were buried by landslides or blown down by molten rock hurled at speeds up to 1000 km/h (Weyerhaeuser 2006). The eruption essentially destroyed all aboveground life within ca. 600 sq km surrounding the summit (Lawrence and Ripple 1998). Our study was conducted in September of each year beginning in 1985, five years after the eruption, through 2004. The Pumice Plains site is in the heart of the blast zone, near the base of Mount St. Helens. The Green River site is within the outer reaches of the blast zone and therefore is experiencing a faster vegetation recovery. Regeneration of vegetation is slow at both areas owing in part to high ash levels (Weyerhaeuser 2006).

Columbia View Park Expansion Plan: St. Helens, Oregon

Columbia View Park Expansion Plan: St. Helens, Oregon

Columbia View Park Expansion Plan 13 Recommendations Community feedback suggests that one of the most valued features of the park is the spectacular view of the Columbia River and Mount St. Helens. “Columbia View” is in the park’s name after all. In the park design process, careful attention should be paid to preserve this scenic view. The community wants more amenities, but at the same time, they are concerned that new structures such as new stage might block the scenic view. Also, access to the river is one of the most highly desired elements from community feedback. Currently people are only able to walk along the river in the grassy lawn area or the vacant gravel area. Constructing a paved trail could bring in more pedestrians to enjoy the river in comfort. Currently the park is closed after sunset, but community members think lighting could improve safety at night and allow nighttime activities.

St Helens Historic Settlement Study

St Helens Historic Settlement Study

Significant Post-Med Activity: Parr appears to have developed from the growth of two main industries. A number of chemical works and collieries became well established during the nineteenth century including Parr Alkali Works and Ashton’s Green and Broad Oak collieries. The success of such industries relied, in part, on the Sankey Canal that provided access to coalfields in St Helens and saltworks in Cheshire and Liverpool. There were also a number of railways servicing the collieries. St Helens Flint Glass Works was also in operation. (4)

Muslims at Mount Hira

Muslims at Mount Hira

During the month of Ramadan, as Muhammad sat meditating in a cave on Mount Hira, an angel in the form of a man came to him. The angel said, “Recite!” Muhammad said, “What shall I recite?” The angel overwhelmed Muhammad in an embrace, and then released him and said again, “Recite!” Muhammad repeated, “What shall I recite?” and again the angel overwhelmed him in an embrace. This happened a third time, after which the angel said, “Recite in the name of your Lord who created—created man from clots of blood.” According to Muslim belief, on this and several other occasions, Muhammad heard the angel Gabriel calling him to be the messenger of God.
