La pr\u00e9sence de l\u2019eau a jou\u00e9 un r\u00f4le majeur dans l\u2019histoire, l\u2019urbanisation et l\u2019\u00e9conomie de la ville.<\/p>\n<p><strong>La Loire<\/strong><\/p>\n<p>La Loire est le principal cours d\u2019eau de Nantes. Elle traverse la ville d\u2019est en ouest avant de poursuivre son cours vers l\u2019estuaire puis l\u2019oc\u00e9an Atlantique.<\/p>\n<p>Elle a notamment favoris\u00e9 :<\/p>\n<ul>\n<li>le d\u00e9veloppement historique du port de Nantes ;<\/li>\n<li>le commerce fluvial et maritime ;<\/li>\n<li>l\u2019implantation d\u2019activit\u00e9s industrielles ;<\/li>\n<li>le d\u00e9veloppement des quartiers de l\u2019\u00eele de Nantes et des anciens secteurs portuaires.<\/li>\n<\/ul>\n<p>Dans Nantes, la Loire se divise notamment autour de plusieurs bras et \u00eeles, dont l\u2019\u00eele de Nantes, situ\u00e9e entre les bras de la Madeleine et de Pirmil.<\/p>\n<p><strong>L\u2019Erdre<\/strong><\/p>\n<p>L\u2019Erdre est le principal affluent de la Loire dans la ville. Elle arrive du nord et rejoint la Loire dans le centre de Nantes, \u00e0 proximit\u00e9 du canal Saint-F\u00e9lix.<\/p>\n<p>L\u2019Erdre est une rivi\u00e8re relativement calme, bord\u00e9e de quais et d\u2019espaces verts. Elle constitue \u00e9galement un \u00e9l\u00e9ment important du paysage urbain nantais.<\/p>\n<p><strong>Le canal de Nantes \u00e0 Brest<\/strong><\/p>\n<p>Nantes constitue l\u2019extr\u00e9mit\u00e9 orientale du canal de Nantes \u00e0 Brest. Le canal permet historiquement une liaison navigable entre la Loire et le r\u00e9seau fluvial de Bretagne.<\/p>\n<p>\u00c0 Nantes, son parcours est notamment associ\u00e9 \u00e0 l\u2019Erdre et au canal Saint-F\u00e9lix.<\/p>\n<p><strong>La S\u00e8vre Nantaise<\/strong><\/p>\n<p>Au sud de la ville, la S\u00e8vre Nantaise rejoint la Loire \u00e0 proximit\u00e9 de Nantes, \u00e0 Nantes Sud et dans les communes voisines, notamment \u00e0 Rez\u00e9 et Vertou. Elle constitue l\u2019un des principaux cours d\u2019eau du sud de l\u2019agglom\u00e9ration.<\/p>\n<p><strong>Les zones humides<\/strong><\/p>\n<p>Le territoire nantais et son environnement comprennent \u00e9galement des zones humides, prairies inondables et petits cours d\u2019eau. Ces milieux jouent un r\u00f4le dans la r\u00e9gulation des eaux, la biodiversit\u00e9 et la pr\u00e9vention des inondations.<\/p>\n<p><strong>Importance de l\u2019hydrographie<\/strong><\/p>\n<p>L\u2019hydrographie a profond\u00e9ment marqu\u00e9 Nantes. La ville s\u2019est d\u00e9velopp\u00e9e autour de la Loire et de ses affluents, et son patrimoine urbain conserve de nombreuses traces de son pass\u00e9 fluvial et portuaire.
