Assessment of rainwater-generated pollution in karst regions

U radu se analiziraju problemi proračuna srednje godišnje veličine tereta zagađenja oborinskih voda urbanih područja. Bez poznavanja tih podataka ne može se planirati i gospodariti kakvoćom voda i obalnim morem. Postoji više metoda koje se koriste za proračun, a tipične su prikazane u ovom radu. Međutim, za područje krša metoda proračuna godišnjeg tereta zagađenja nije razvijena, te je stoga predložena nova metoda značajke koje su prikazane na primjeru Kaštelanskog zaljeva.Problems of determining average annual values of pollution load generated by rainwater in urban areas are analyzed. The quality of water and coastal sea can not be planned and improved without a proper access to relevant information. Several methods are currently used in this calculation. Typical ones are presented in the paper. However, as the method for calculating an annual pollution load in karst areas has not as yet been developed, the authors present main features of a new method and use Kastela bay to illustrate the method
