Statistična analiza gospodarsko enakovrednih nalivov

Panjan, Jože (author), Bogataj, Marija (author), Kompare, Boris (author)

Statistično analizo padavinskih podatkov uporabljamo za oblikovanje kanalizacijskega omrežja in črpališč, ugotovitev trajanja in pogostosti prelivanja razbremenilnikov in zadrževalnikov oziroma za določitev kritičnega dotoka na komunalno čistilno napravo ali izpust v vodotok (npr. iz avtocest). Pri tem sta osnovna podatka jakost in trajanje naliva pri izbrani povratni dobi. Opisani so postopki, ki se uporabljajo za analizo gospodarsko enakovrednih nalivov (GEN) pri nas in v tujini. Natančneje je prikazana metoda stohastičnega modeliranja, ki je uporabna predvsem za ugotovitev verjetnosti pojava delnih nalivov višjih pogostosti in za določitev spodnje meje vrednotenja nalivov. Prikazani so rezultati izračunov za vrednotenje padavin na podlagi statistične analize opazovanih nalivov na območju Ljubljane.

• Title: Statistical analysis of the equivalent design rainfall

Abstract

Statistical analyses of rainfall data are used for the design of sewerage systems and pump-stations, for the evaluation of the duration and the frequency of overflow in runoff detention facilities, for the determination of the critical influence on a municipal wastewater-treatment plant or for the protection of watercourses from storm-water runoff (e.g., from highways). The basic data in this calculation are the intensity and the duration of a rainstorm. Different procedures used in the analysis of Equivalent Design Rainfall (EDR) in Slovenia and abroad are described. The stochastic model used is presented in more detail because of its applicability for the determination of the probability of the occurrence of partial rainfalls of higher frequencies and the determination of the lower limit of rainfall evaluation. Computation procedures and the results of the evaluation of rainfall data according to the stochastic model are presented for Ljubljana.
