a problem that is so serious that in 2009 the<a href=\"http:\/\/www.phnompenhpost.com\/national\/pm-warns-riverbank-collapse\"> Prime Minister of Cambodia warned<\/a> about the threats of the &#8220;seasonal collapse of riverbanks&#8221;.\u00a0 Earlier this year <a href=\"http:\/\/www.cambodiadaily.com\/archives\/three-missing-after-mekong-riverbank-collapse-in-kandal-52710\/\">a woman and two young children were killed by riverbank collapse<\/a> in Kandal Province in Cambodia.\u00a0 This image, from the same article, is a nice illustration of the problem:<\/p>\n<div id=\"attachment_13104\" style=\"width: 650px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/blogs.agu.org\/landslideblog\/files\/2014\/10\/14_10-riverbank-1-e1414047335506.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-13104\" class=\"wp-image-13104 size-full\" src=\"https:\/\/blogs.agu.org\/landslideblog\/files\/2014\/10\/14_10-riverbank-1-e1414047335506.jpg\" alt=\"Riverbank\" width=\"640\" height=\"425\" \/><\/a><p id=\"caption-attachment-13104\" class=\"wp-caption-text\"><a href=\"http:\/\/www.cambodiadaily.com\/archives\/three-missing-after-mekong-riverbank-collapse-in-kandal-52710\/\">Cambodia Daily<\/a><\/p><\/div>\n<p>.<\/p>\n<p>Over in Australia there is a <a href=\"http:\/\/www.abc.net.au\/news\/2014-02-07\/murray-study-considers-riverbank-collapse\/5245470\">very nice project in progress<\/a>, in which I have some involvement, looking at riverbank collapse along the Murray River, where<a href=\"https:\/\/blogs.agu.org\/landslideblog\/2011\/02\/15\/riverbank-collapse-on-the-lower-murray-river-in-australia\/\"> collapsing riverbanks were a major problem<\/a> when the river level was very low in the drought of a few years ago.\u00a0\u00a0 There is a very nice e-poster by the research team <a href=\"http:\/\/www.eposters.net\/pdfs\/riverbank-collapse-on-the-lower-river-murray-recent-recent-phenomenon-or-long-term-geomorphic.pdf\">online explaining the provisional results of this work\u00a0<\/a> &#8211; NB this is a pdf.<\/p>\n<p>Whilst the mechanisms of riverbank collapse might initially seem to be simple, they are in reality extremely complex, not least because the stress state is very dynamic due to the effects of water coming into the bank from the river, from the bank top and through the ground.\u00a0 In many rivers water levels rise and fall quickly, causing unusually rapid pore water pressure changes.\u00a0 And of course humans have an annoying habit of messing around with rivers, and riverbanks, too.<\/p>\n<p>Anyway, there is an <a href=\"https:\/\/www.youtube.com\/watch?v=dEPsxaOuqa0\">interesting video on Youtube<\/a>, which I don&#8217;t think I&#8217;ve seen before, showing a riverbank collapse event.\u00a0 I am not sure where this happened.<\/p>\n<p>http:\/\/www.youtube.com\/watch?v=dEPsxaOuqa0<\/p>\n<p>.<\/p>\n<p>Clearly the river is in flood, but the complexity of the failure, and its progressive nature, illustrates how complex the mechanics can be.<\/p>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content -->","protected":false},"excerpt":{"rendered":"<p>A nice new video has appeared on Youtube showing a progressive riverbank collapse event, although the location is not certain<!-- AddThis Advanced Settings generic via filter on wp_trim_excerpt --><!-- AddThis Share Buttons generic via filter on wp_trim_excerpt --><\/p>\n","protected":false},"author":22,"featured_media":13104,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[271,469,524,576],"class_list":["post-13103","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-uncategorized","tag-cambodia","tag-featured","tag-riverbank","tag-riverbank-collapse"],"_links":{"self":[{"href":"https:\/\/blogs.agu.org\/landslideblog\/wp-json\/wp\/v2\/posts\/13103","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/blogs.agu.org\/landslideblog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/blogs.agu.org\/landslideblog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/blogs.agu.org\/landslideblog\/wp-json\/wp\/v2\/users\/22"}],"replies":[{"embeddable":true,"href":"https:\/\/blogs.agu.org\/landslideblog\/wp-json\/wp\/v2\/comments?post=13103"}],"version-history":[{"count":0,"href":"https:\/\/blogs.agu.org\/landslideblog\/wp-json\/wp\/v2\/posts\/13103\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/blogs.agu.org\/landslideblog\/wp-json\/wp\/v2\/media\/13104"}],"wp:attachment":[{"href":"https:\/\/blogs.agu.org\/landslideblog\/wp-json\/wp\/v2\/media?parent=13103"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/blogs.agu.org\/landslideblog\/wp-json\/wp\/v2\/categories?post=13103"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/blogs.agu.org\/landslideblog\/wp-json\/wp\/v2\/tags?post=13103"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
