Abstract

Drenážní odvodnění je v podmínkách ČR plošně velmi významným melioračním opatřením. Jeho funkce jsou ve společnosti vnímány diametrálně odlišně. Rozlišujeme pohled vlastníka pozemku, hospodařícího zemědělce, správce vodního díla nebo ekologa. Tak, jak se mění zemědělství i klimatické podmínky, je nutné posoudit i změněné podmínky ve vztahu k existujícímu odvodnění. S tím souvisí i další strategie jejich podpory a správy. Dominantní roli v ČR v tomto ohledu sehrává uživatel pozemku, nikoli stát nebo vlastník, jak by bylo zřejmě správné. V příspěvku jsou dokumentovány výsledky provedených šetření k popisu stavu drenáží, způsobů jejich údržby, četnosti výskytu závad a možnosti využití moderních technologií a metod DPZ pro jejich identifikaci i pro analýzu odvodněného území v širších souvislostech. Výstavba odvodnění zásadně změnila ráz české krajiny. Podpořila intenzifikaci zemědělství, a tím i úbytek řady přírodních stanovišť a přirozených vodních toků. Zvyšování extremity hydrologických jevů a stárnutí těchto vodohospodářských děl zvyšuje naléhavost řešení jejich další existence v různých částech ČR: zachování pro zemědělskou produkci i postupný útlum až likvidaci pro obnovu přirozených stanovišť.
