Historick\u00e1 regul\u00e1cia verzus hydromorfol\u00f3gia<\/p>\n

V 19. storo\u010d\u00ed tvorila rieka Dunaj pri dne\u0161nom hlavnom meste nepredv\u00eddate\u013en\u00fa sie\u0165 ramien a ostrovov. Z d\u00f4vodu rozvoja lodnej dopravy a protipovod\u0148ovej ochrany navrhol taliansky in\u017einier Enea Grazioso Lanfranconi z\u00fa\u017eenie a stabiliz\u00e1ciu toku. V\u00fdsledkom bolo vybudovanie s\u00favisl\u00e9ho mantinelu z obrovsk\u00fdch skaln\u00fdch balvanov. Tie brehy rieky neprirodzene \u201ezviazali\u201c a ohrani\u010dili do jedn\u00e9ho pevn\u00e9ho koryta.<\/p>\n

Tak\u00e1to trval\u00e1 fix\u00e1cia koryta s\u00edce chr\u00e1ni zastavan\u00e9 \u00fazemie, mosty, pr\u00edstavy a hr\u00e1dze, no v modernom ch\u00e1pan\u00ed vedy, takzvanej hydromorfol\u00f3gie, pr\u00e1ve tento m\u00far predstavuje z\u00e1sadn\u00fa prek\u00e1\u017eku. Rieka toti\u017e v zovret\u00ed kame\u0148ov str\u00e1ca svoju dynamiku a nem\u00f4\u017ee vo\u013ene uklada\u0165 piesok a \u0161trk. Navy\u0161e sa tak preru\u0161uje prirodzen\u00e9 spojenie vody s okolitou krajinou. Preto sa dnes v \u00fasekoch, kde to bezpe\u010dnos\u0165 dovo\u013euje, umel\u00e9 kamenn\u00e9 bari\u00e9ry likviduj\u00fa.<\/p>\n
