waters from source of Klokun, till receives water from Vriostica river, it is named Mlade.

From Humac till mouth to the Neretva rives, its name is Trebizat

At village Studenci, Trebizat receives water from water stream Studencica.

Pressures on natural hydrological regimePressures on natural hydrological regime

existence of numerous artificial hydro technical buildings that affect the water regime: at 1950 tunnel was built (“Brzotok”) for evacuation of

high waters from natural retenzion Nuga; HPP Rastovaca (1956 - Topala, tributary of Ricina);



HPP Rastovaca (1956 - Topala, tributary of Ricina); HPP Tribistov (1988 – Ricina); HPP Pec Mlini (Sept. 2004 - Tihaljina) numerous irigation channels for agriculture production

are present; Hambar Parilo – “Brza voda” and others...
