The article analyses the effects produced by the anthropic intervention (by embankment, topographical leveling, drainage, irrigation and chemical processing) to hydrogeological and hydrochemical regime from polder Balta Mare a Brailei. After these changes, Balta Mare a Brailei is in unstable equilibrium, determined by the negative effects visible to 50 years since the end of natural drainage.
