- Povzetek: Eksperimentalna porečja, ki so pogosta tudi v svetovnem merilu, so pomemben dejavnik pri razvoju hidrologije, saj nam omogočajo opazovanje in proučevanje različnih procesov, kot so padavine, površinski odtok, premeščanje sedimentov, procesi erozije, itd. V prispevku so predstavljeni nekateri merski instrumenti, s katerimi smo opremili dve sosednji eksperimentalni porečji (Mačkov graben ter Kuzlovec) ter njuno okolico. Obe porečji sta del porečja reke Gradaščice, ki se izliva v Ljubljanico, slednja pa je del porečja reke Save. V članku so prikazani nekateri preliminarni rezultati analiz izmerjenih podatkov s poudarkom na suspendiranih snoveh. Ugotovili smo, da do nastopa maksimalne vrednosti koncentracij suspendiranih snovi v povprečju pride pred nastopom konice pretoka, kar je pogosto značilnost manjših porečij, kjer so potencialni viri sedimentov locirani blizu struge oz. v strugi sami. Poleg tega je očitno, da imajo izraziti padavinski dogodki velik vpliv na premeščanje suspendiranih snovi. Meritve s časovnim korakom krajšim od ½ ure se bodo na obeh eksperimentalnih porečjih nadaljevale, s čimer bomo pridobili kvalitetne podatke, s katerimi bomo lahko nadgradili znanje o hidroloških procesih.
