The Renfrew County Landslide<\/h5>\n

At about 2 am on 29th March 2016 the Renfrew County landslide occurred near to Horton Township, west of Ottawa in Canada.\u00a0 This landslide, which is reported to have had a surface area of 10 hectares, slipped into and blocked the Bonnechere River.\u00a0 Various local news agencies<\/a> have images, of which the best overview is on the Ottawa Citizen<\/a>:<\/p>\n

The level of the impounded water rose by 7 m, damaging a cottage, a hunting camp and a hydroelectic plant, amongst other impacts.\u00a0 After about seven hours the dam breached, releasing a flow at a rate of about 250 cumecs (cubic metres per second).<\/p>\n

The Ottawa Citizen report<\/a> also carries a brief interview with Greg Brooks<\/a> from Natural Resources Canada<\/a>:<\/p>\n

\u201cThere are definitely ancient, large landslides that are mapped in that area,\u201d said Greg Brooks, a landslide expert with Natural Resources Canada. \u201cThis is another one…You can\u2019t stop them. When they\u2019re going to happen, they\u2019re going to happen.\u201d\u00a0 He said the land includes a lot of leda clay \u2014 the former bottom\u00a0of the ancient Champlain Sea, which is prone to collapsing suddenly, especially when it is sodden. Early spring, while the ground is thawing, is prime time for these landslides.\u00a0 The size, though dramatic, isn\u2019t a surprise, Brooks said.\u00a0 \u201cSensitive clay landslides can easily be that\u00a0size, or larger.\u201d<\/p><\/blockquote>\n

That bulge into the river might be the sign of some previous instability perhaps?<\/p>\n

The best information and data about the landslide sits on the Twitter account of James Power, a Paramedic Drone Consultant (who knew there was such a job?) with Renfrew County Paramedics.\u00a0 His twitter handle is @IASF07<\/a>.\u00a0 He, and his colleague Steve Osipenko (@osipenko_steve<\/a>) have tweeted some great images<\/a> and videos<\/a> of the landslide, taken by his drone, including this photograph:<\/p>\n
