The project aims to develop ecological indicators for quantitative assessment of the degree of spatial evolution of hydrological processes, and to study the hydrobiological processes taking place in highly aqualized fens. The ultimate goal will be to develop a conceptual model of fens for incorporation into a hydrological forecasting model.<\/p>\n\n\n\n<p>The overall findings on the nature and importance of the aqualysis process in fens and on certain characteristics of their hydrological regime, added to the imperative to better characterize the budget on an annual basis, lead us to pursue the ecohydrological study of fens by approaching in an entire basin (or sub-basin) the integrated analysis of all facets of the hydrological budget, including the carbon budget which is dependent on the hydrological conditions prevailing each year.<\/p>\n\n\n\n<p>Objectives:<\/p>\n\n\n\n<ol class=\"wp-block-list\" type=\"1\">\n<li>Analysis of hydrological processes in highly aqualized (&gt; 50%) fens in Mid-Northern Qu\u00e9bec;<\/li>\n\n\n\n<li>Develop conceptual models of fens to incorporate into a hydrological forecasting model ;<\/li>\n\n\n\n<li>Develop ecological indicators for quantitative assessment of the degree of spatial evolution of hydrological processes;<\/li>\n\n\n\n<li>Develop remote sensing monitoring procedures for certain elements of the water budget;<\/li>\n\n\n\n<li>Perform a greenhouse gas (GHG) budget for fens and link it to the hydrological parameters of fens.<\/li>\n<\/ol>\n<\/div>\n<\/div>\n\n\n\n<p><\/p>","protected":false},"excerpt":{"rendered":"<p>\u00c9tude \u00e9cohydrologique des tourbi\u00e8res min\u00e9rotrophes de la r\u00e9gion de Laforge-1,&#8230;<\/p>","protected":false},"author":4,"featured_media":1159,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_kad_post_transparent":"","_kad_post_title":"","_kad_post_layout":"","_kad_post_sidebar_id":"","_kad_post_content_style":"","_kad_post_vertical_padding":"","_kad_post_feature":"","_kad_post_feature_position":"","_kad_post_header":false,"_kad_post_footer":false,"_kad_post_classname":"","footnotes":""},"categories":[1],"tags":[29,38,39],"class_list":["post-170","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-uncategorized","tag-carbone","tag-holocene","tag-tourbiere-minerotrophe"],"_links":{"self":[{"href":"https:\/\/cpaleo.uqam.ca\/en\/wp-json\/wp\/v2\/posts\/170","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/cpaleo.uqam.ca\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/cpaleo.uqam.ca\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/cpaleo.uqam.ca\/en\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/cpaleo.uqam.ca\/en\/wp-json\/wp\/v2\/comments?post=170"}],"version-history":[{"count":10,"href":"https:\/\/cpaleo.uqam.ca\/en\/wp-json\/wp\/v2\/posts\/170\/revisions"}],"predecessor-version":[{"id":1629,"href":"https:\/\/cpaleo.uqam.ca\/en\/wp-json\/wp\/v2\/posts\/170\/revisions\/1629"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/cpaleo.uqam.ca\/en\/wp-json\/wp\/v2\/media\/1159"}],"wp:attachment":[{"href":"https:\/\/cpaleo.uqam.ca\/en\/wp-json\/wp\/v2\/media?parent=170"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/cpaleo.uqam.ca\/en\/wp-json\/wp\/v2\/categories?post=170"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/cpaleo.uqam.ca\/en\/wp-json\/wp\/v2\/tags?post=170"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
