A satellite image could be a clue in determining whether river erosion was a factor in the fatal hillside collapse in Washington state, a landslide expert said.

The undated image on the Google Earth website was apparently taken some time after the 2006 landslide in Oso forced engineers to construct a retaining wall along the Stillaguamish River, reported NBC affiliate KING5. The wall was created to reinforce the riverbank.

The image shows a bend in the north fork of the Stillaguamish and what appear to be broken-off logs cluttering the river at the northeast end of the wall. The wall was swept way Saturday in a mile-long mudslide that flattened homes on the other side of the river, killing at least 17 people.

Its too early to say whether the walls failure played a part in the slide, but it could be studied in the event the river had eaten away at the hillsides stability, said Dave Montgomery, a geologist at the University of Washington.

You can clearly see the river cutting into the toe of the slope, Montgomery told KING5.

A Google Earth satellite image shows the bend in the Stillaguamish River in Oso, Wash., where a retaining wall appears to have broken apart.

But the Stillaguamish Tribe of Indians, which oversaw the building of the $1 million wall, doesnt believe the walls condition contributed to the collapse. The tribes environmental manager, Pat Stevenson, told KING5 that the wall was also built to hold back sediment that was hurting the river's fish run and not meant to support the entire slope.

The tree-filled hillside has been known as a landslide area for more than 60 years, and the river has eroded the base of it since at least the 1950s, geologists said.

While there was state-approved logging at the top of the hillside in 2005, the area immediately around the head of the slide was restricted from harvesting, according to state officials.

A Seattle Times report, however, found that logging was still done in the restricted area. Logging can contribute to slides because it removes trees that would otherwise absorb the water on the land.

Boston, MA (PRWEB) March 28, 2014

Infrasense, Inc., a national leader in infrastructure nondestructive evaluations, is carrying out subsurface investigations for 44 bridge decks throughout Minnesotas District 6 and Metro regions. The completion of this project will bring the total bridge decks evaluated in Minnesota to 181 (over 3.25 million square feet) since 2009. Ground Penetrating Radar (GPR) tests were performed on each bridge deck, with accompanying underside visual inspections planned for the spring. These tests provide a condition assessment of the reinforced concrete bridge decks without requiring any cores or exposed rebar, and with minimal disruption to traffic flow.

Ground penetrating radar (GPR) data is collected at highway speeds to estimate rebar depth, corrosion conditions and deteriorated concrete. The GPR data is collected in a series of lines spaced 3 feet transversely across the width of the deck, with each line representing a cross sectional slice of the deck at a particular offset. Decks in good condition consist of strong and uniform radar reflections from the rebar. GPR data with weak and inconsistent reflections indicate rebar-level deterioration in the bridge deck.

Recently a study evaluating the accuracy of Infrasense's results provided to the Minnesota DOT was carried out by an independent consultant for MnDOT. The study compared the predicted quantities for 12 decks surveyed by Infrasense against subsequent construction repair quantities. The study found that, on average, Infrasenses predicted deterioration quantities were within 3.5 % of the documented construction quantities.

Ground penetrating radar surveys provide transportation agencies with accurate and comprehensive bridge deck condition information, enabling effective preservation, rehabilitation, and replacement decisions. With large bridge deck inventories, highway agencies have primarily relied on visual inspection at the network level. Since the mechanisms of deterioration occur below the surface, their manifestations are not readily seen in the visual inspections, often leading to subsequent project-level focus.

Traditionally, highway agencies have employed sounding (chain or hammer) to identify delaminated areas for project-level rehab. Although sounding has proven reliable, the labor and closures required for a sounding survey makes it prohibitive for obtaining data of a large number of decks. Also, sounding is not effective when there is an asphalt overlay. In response to these limitations, a number of highway agencies, including MnDOT, have utilized alternative methods, particularly ground penetrating radar.

The decks seem to be clearing for second phase expansion of Dhamra Port, an equal joint venture between Larsen & Toubro (L&T) and Tata Steel after the promoters obtained environment clearance in January.

The state government has asked its ports directorate to assess land need for Phase-II expansion of the deep draught port developed off the coast of north Odisha. The port project is implemented by Dhamra Port Company Ltd (DPCL) where both Tata Steel and L&T hold 50 per cent equity each.

The requirement of land as indicated by the port developers may kindly be examined in line with the guidelines prepared by Rites Ltd and your views in the matter may be offered for taking further action, Arun Chandra Mangaraj, under secretary (commerce & transport) wrote to director of ports & inland water transport, Odisha.

Santosh K Mohapatra, chief executive officer, DPCL said, The Dhamra port has around 300 acres of surplus land. We had sought 745 acres land from the government. About 1,000 acres of land would suffice for the second phase capacity expansion.

Rites, the engineering and consultancy arm of Indian Railways, has benchmarked land need for developers of non-major port projects in Odisha. In its final report submitted to the state commerce & transport department. Rites has suggested a thumb rule allotting 50 acres of land for every million tonne of cargo handling capacity proposed by the developer.

Dhamra port which began commercial operations in May 2011 has been hit hard by curbs on iron ore exports.

After a slump in the iron ore export market, the port was aiming to boost its revenues through handling of diversified cargo like container cargo, liquid cargo, LNG (liquefied natural gas) and crude oil.

DPCL had chalked out Rs 10,000-crore expansion plan that was to ramp up its berth strength to 13 from two presently and upgrade cargo handling capacity four-fold from 25 million tonne per annum (mtpa) to 100 mtpa in five years.

The second phase capacity ramp up would also pave the way for a five mtpa LNG (liquefied natural gas) terminal to be set up within the port premises by Indian Oil Corporation Ltd (IOCL). The terminal to be setup at a cost of Rs 5,000 crore needed 150 acres of land. Both IOCL and DPCL had signed an MoU for the project.

Presently, the port with two berths, is capable of handling 12 million tonne of imported dry bulk cargo and 13 million tonne of dry bulk cargo for exports.
