- Abstract
- This work examines the possibility of using a surface hydrology model in a karst environment. In these
kinds of environments, deterministic models such as SWAT, and the majority of surface hydrology models,
are unable to compute the added contribution due to subsurface circulation. This can result in a substantial
under-estimation of the river flows. Therefore such models are generally not applied by
researchers to complex watersheds. Often the simulation of spring discharges is in itself very complex,
making it even more difficult to simulate river discharge in karst environments, where the flow contribution
coming from karst conduits cannot be directly measured. The present paper investigates the
advantages of applying Wavelet Analysis (WA) to this field. The statistical method of WA has been
recently applied in hydrogeology for interpreting spring discharges, and in hydrology to describe the variability
of streamflows, thus providing insights into their dynamical link with the dominant modes of climate
variability. However it has not yet been directly used to support the understanding of river flow
components in karst environments. What is more, the present work proposes using WA not merely to
assist in the analysis of experimental series, but also as a tool for interpreting the data series generated
by the modelling process. In this paper we shall describe how WA can potentially be applied to help
define the nature and behaviour of the karst contribution to river flows, thereby improving the future
performance of surface hydrological modelling. (literal)
