Nitrate ground pollution dispersion

U ovome radu je obrađena tema onečišćenja podzemnih voda nitratima. Prikazan je utjecaj poljoprivrede kao najvećeg onečišćivača. Nakon toga je obrađen prijenos onečišćivača u podzemnim vodama preko difuzijsko-disperzijske jednadžbe. U zadnjem dijelu je opisan rad u programu SMS (Surface-water modeling system), gdje se dobije model vodocrpilišta za analizu. Modeli omogućuje praćenje širenja i dotok onečišćivača u podzemne vode.This paper deals with the topic of groundwater pollution by nitrates. Agriculture is presented as the biggest pollutioner. Then the transfer of pollutants in groundwater was defined with diffusion-dispersion equation. The last part describes the work in SMS program (Surface-water modeling system) where the model for water pumping station is made. The models allow monitoring of the spread and inflow of pollutant in the groundwater
