Abans de l&#8217;episodi de pluges generat pel Gloria, d&#8217;un cabal de partida&nbsp;de poc m\u00e9s d&#8217;1 m\u00b3\/s&nbsp;es va arribar&nbsp;a un pic de cabal registrat de 376 m\u00b3\/s, i es va superar la llera de crescuda extraordin\u00e0ria. Tanta pluja i tanta aigua va provocar que el riu arrib\u00e9s a la desembocadura ben carregat de sediments. Uns sediments que va dipositar en arribar al mar.<\/p>\n<p>Aquesta barra de terra i sorra s&#8217;ha format a partir dels sediments transportats pel riu durant el temporal Gloria. Una&nbsp;barra que guanya m\u00e9s de 170 metres al mar, amb una llargada paral\u00b7lela a la costa d&#8217;uns 400 metres. L&#8217;abs\u00e8ncia de pantans al llarg del riu va permetre que els sediments arribessin al mar. \u00c9s aquesta din\u00e0mica fluvial i costanera la que permet el creixement del delta. Aix\u00f2 \u00e9s un bon exemple per veure com \u00e9s la din\u00e0mica dels deltes, com es nodreixen. Si el riu no transporta sediments, la falta d&#8217;aquests dip\u00f2sits provoca la seva regressi\u00f3, tal com passa al delta de l&#8217;Ebre.<\/p>\n<p>A causa de la gran crescuda del cabal \u0096mai vista, en 50 segons, per alguns ve\u00efns de poblacions a tocar del riu\u0096 la Tordera es va desbordar en nombrosos indrets del curs mig i baix, va inundar m\u00e9s de 800 hect\u00e0rees, va obligar a desallotjar ve\u00efns i va fer caure dos ponts a Malgrat de Mar.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>El temporal Gloria&nbsp;que varem viure els darrers dies de gener va modificar la costa catalana deixant grans zones erosionades i algunes amb sobreacumulaci\u00f3 de sediments.
