The Experimental Monitoring of the Water Regime in the Reka River

Reka Reka, s prispevno povrsino 422 km2 , ponika v Skocjanskih jamah, ki jih je UNESCO leta 1986 proglasil za svetovno dediscino. V sedemdesetih letih je bila Reka ena od najbolj onesnaženih rek v Sloveniji. V casu visokih vod leta 1999 in 2000 smo izvedli meritve hitrosti, kalnosti, vrste fizikalnih in kemicnih parametrov ter teste strupenosti. Glavni cilji teh pionirskih meritev so bili preveriti mersko opremo v terenskih pogojih visokih voda, zbrati cimvec podatkov ter primerjati uporabnost opreme. The river Reka, with 422 square kilometres of drainage area sinks into the Skocijan Cave system, which was proclaimed by UNESCO as a World Heritage Site in 1986. In the seventies, the Reka river was one of most polluted rivers in Slovenia. During floods in 1999 and 2000, experimental measurements of velocity, water level, suspended sediment transport, chemical parameters and toxicity tests were conducted. The main tasks in the first stage of the investigation: check the equipment in field conditions and test the toxicity of water in particular cross sections. In the paper, the measurements and some discussion of the results and applicability of equipment are presented.
