Osnovni zadatak hidrološke Studije bio je definiranje hidroloških parametara za potrebe utvrđivanja režima oticanja -prostorna i vremenska raspodjela oticanja, u razdoblju sistemskih hidroloških osmatranja i mjerenja protoka, na cjelovitom slivu rijeke Trebižat

The main task of the Study was hydrological parameters definition for the river system Vrljika–Tihaljina-Mlade-Trebižat –definition of the flow regime, eg. areal and temporal definition of flow regime for the period of existing hydrological stations functioning.

Sa hidrološkog aspekta važno je naglasiti složenost prirodnog režima tečenja – skoro je nemoguće tačno odrediti slivnu površinu; ipak Studija daje podatak o veličini slivne
