Secondary title: |
Stream flow measurements with two different instruments |
Secondary abstract: |
Hydrometry is the science of measurement of various parameters characterizing flow in natural or artificial waterways and pipelines. Two main variables in order to characterize the flow are water height (H) and discharge (Q). Thesis refers to the flow of the water volume flowing through the selected area or cross-section per unit of time.
Over time, the instruments and methods of measuring the streamflow were changed. In the first part of the thesis some of the most used methods for measuring flows in open streams are described. Two most common instruments, namely: Doppler flow meter FlowTracker Handheld ADV (velocity – area method) and FloTracer (acting on the basis of the method of dilution) were introduced.
The second part of the thesis is the practical part. Both instruments were used in practice. Namely, in a small stream Mačkov graben in three different time periods. Results of all measurements are presented and comparison of the results of the both instruments is done. |

Abstract (ePrints): |
Hidrometrija je znanost merjenja različnih parametrov, ki označujejo tok v naravnih ali umetnih vodotokih in ceveh. Dve glavni spremenljivki, ki sta značilni za tok sta višina vode (H) in pretok vode (Q). Diplomska naloga se nanaša na pretok vode, ki je prostornina, ki steče skozi izbrano površino oz. prečni prerez na enoto časa.
S časoma so se instrumenti in metode merjenja pretoka zelo spreminjale. V prvem delu diplomske naloge so opisane nekatere najbolj uporabljene metode merjenja pretokov v odprtih vodotokih. Največ časa pa smo posvetili dvema najpogostejšima instrumentoma, to sta: Dopplerjev merilnik pretočnih hitrosti FlowTracker Handheld ADV (metoda hitrost – površina) in merilnik FloTracer, ki deluje na podlagi metode razredčenja.
Drugi del diplomske naloge je praktični del, saj smo oba instrumenta tudi uporabili v praksi. In sicer, na manjšem hudourniku Mačkov graben, v treh različnih časovnih obdobjih. Podani so rezultati vseh meritev, ter primerjava rezultatov obeh instrumentov med seboj. |
