This wellspring is continuation of the Vrljika (Matica) river which sunk few kilometers before and on a plain above, at the southeastern end of Imotsko Polje near Drinovci in Bosnia and Herzegovina.

At least nine names are regularly used, and few other are known to be used as well - overall some thirteen names are known to be used at different point in times and/or by different communities along its course, at various location and for different sections: the Vrljika (from its original wellspring at Proložac to Kamenost (Podbablje)), the Matica (from Kamenmost in Croatia to Drinovci in Bosnia and Herzegovina), the Tihaljina (from wellspring at Peć Mlini to Mladi), the Mlade (from Mlade to Perila), the Stari (Old) Prokop & the (New) Prokop or the Kanal (from Perila to Jegetina), and the Trebižat (from Jegetina, through Ljubuško Polje, till confluence with the Neretva in village Struge near Čapljina); also at various places the river is called Brina, Culuša, Ričina, Suvaja (at Posušje), & Rika.

Similar to Krka Falls and Plitvice Lakes, Trebižat River is also in a constant process of natural tufa deposit.
