Hidrološki modeli

Bonacci, Ognjen (author)

This paper discusses the highly topical issue of forming and using hydrological models. Their significance in water resource management and achieving sustainable development goals is underlined, particularly in the context of climate change. Some shortcomings in hydrological process modelling are pointed out, ones that can significantly affect the probability of achieving reliable results. Given the important role water plays, it is necessary to understand the complexity of producing hydrological models. Indeed, hydrological models themselves play an important role, and they must as such meet several important assumptions. Above all, they must consistently follow the basic principles of hydrology. We find that contemporary modelling technology (computer use, rapid development of numerical methods, use of state-of-the-art monitoring techniques) has strongly surpassed the level of our knowledge regarding physical hydrological processes and their interactions with the living and non-living environments that we aim to model. The complexity of the procedures and the problem of transferring information from one dimension to another in space and/or time have been highlighted.

Abstract

Prispevek obravnava zelo aktualno problematiko oblikovanja in uporabe hidroloških modelov. Izpostavljen je njihov pomen pri upravljanju vodnih virov in doseganju ciljev trajnostnega razvoja, še posebej v luči podnebnih sprememb. Izpostavljene so tudi nekatere pomanjkljivosti v procesu modeliranja hidroloških procesov, ki lahko pomembno vplivajo na verjetnost doseganja zanesljivih rezultatov. Glede na pomembno vlogo vode je pomembno, da razumemo tudi kompleksno problematiko oblikovanja hidroloških modelov. Ti sicer imajo pomembno vlogo, a morajo pri tem izpolnjevati več pomembnejših predpostavk. Predvsem morajo dosledno slediti osnovnim načelom hidrologije. Ugotavljamo, da je sodobna tehnologija modeliranja (uporaba računalnikov, hitro razvijajočih se numeričnih metod kot tudi uporaba sodobnih tehnologij monitoringa) močno presegla raven našega poznavanja hidroloških fizikalnih procesov in njihove interakcije z živim in neživim okoljem, ki jih želimo modelirati. Izpostavljena je kompleksnost postopkov in problematika prenosa informacij iz ene razsežnosti v drugo v prostoru in/ali času. Poudarjena je potreba po nadaljnjem razvoju hidroloških modelov s strogim preverjanjem rezultatov, ki jih modeli dajejo.
