GEOLOGICAL-TECTONICAL STRUCTURE AND HIDROGEOLOGICAL CHARACTERISTICS OF THE STUPČANICA RIVER CATCHMENT AREA

Abstract

The Stupčanica River catchment area belongs to the Bosnia River Basin. It is situated in the central part of the Bosnian Mountains. The catchment area covers 283 km/2 .The Stupčanica River originates when two waterflows Bijesnica and Pištica meet each other upstream from the Pjenovac settlement. In its further flow, from the right side this river receives several larger and smaller streams, of which excelled are Varošnica, Bjelava and Grabovica, and from the left side Dobrovački potok, Čađavica, Studenac, Duboki potok and Jablanica. Numerous sources and springs (permanent and temporary) with significantly less abundance are situated on both valley sides of the Stupčanica, all until the source zone. Beside permanent surface flows, there are temporary ones as well, which existence is conditioned by water plunging into the ground or springs' drying. It has been performed in this paper the analysis of geological-tectonical structure as well as hydrogeological characteristics of the Stupčanica catchment area, from its source and down to Olovo, where together with Bioštica River it makes the River Krivaja Basin. The border of the basin-watershed with its significant part is underground-hydrogeological, very often with zonal character. The watershed has been determined on the base of analyse on geological structure and geomorphological relations as well as examinations on underground relations.
