| Summary: | The river Toplica springs on the east slopes of Kopaonik. It is the biggest
left tributary of the Južna Morava, in which it empties at the town of
Korvingrad. It is 130 km long and the surface of its river-basin amounts to
2180 km². This study estimates the probability of average, minimum and
maximum discharge occurrence on the hydrological profile Pepeljevac on the
Toplica River in the period 1951-2014. Pearson type III distribution was used
for quantifying average, minimum and maximum annual discharge. Results of the
study point out to significant fluctuations in the river Toplica discharge
upstream the hydrological profile Pepeljevac, which is the base for further
study and improvement water management planning in the basin. On the basis of
probability of average annual discharges occurrence, a classification of
years by water richness was done. Mann-Kendal test examined the trend of
Toplica discharge, while Pettit, SNTH, Buishand and von Neumann tests
analyzed homogeneity of the data on the observed profile. Analysis of average
annual discharges shows that years moderately rich in water are the most
numerous (29) with somewhat higher participation of rich in water (16) than
dry (14) years. Coefficients of variation of maximum and minimum annual
discharges for the Toplica river point out to significant fluctuations
upstream the hydrological profile Pepeljevac. These results are the base for
further study and improvement of water management planning in the basin. |
