Computational flood flow of Toplodolska river at Topli Do

Abstract

The paper presents in detail application of the peak over threshold (POT) method for flood flow estimation for the Toplodolska river, gauge station Topli Do. In addition, design flood flows are estimated by means of the synthetic unit hydrograph methodology, and the Limit Intensities Theory. The basis for flood estimation is the 14-year flow record at the Topli Do station and the daily precipitation maximal record. The nearby hydrologic station Visočka Ržana on the Visočica River is used as the control station for calculated flows. Flood flow estimation results are also shown compared to the flood flow envelopes for the territory of Serbia. Computations represent a part of a hydrologic study of water captures for small hydropower plant in the village of Topli Do.

U radu je detaljno prikazana primena metode parcijalnih serija za proračun velikih voda Toplodolske reke u profilu V.S. Topli Do. Računske velike vode ocenjene su još i metodom sintetičkog jediničnog hidrograma - aproksimacija trouglom i teorijom graničnih intenziteta. Korišćeni su podaci osmatranja proticaja na V.S. Topli Do, trajanja 14 godina i osmatranja visine dnevnih padavina. Kao kontrolna stanica usvojena je V.S. Visočka Ržana na reci Visočici. Rezultati ocene velikih voda prikazani su u odnosu na anvelope specifičnih oticaja velikih voda reka Srbije. Proračuni su vršeni u okviru hidrološke studije za profile zahvata planirane male hiroelektrane (MHE) u ataru sela Topli Do.
