| This paper analyses the hydrological functioning of the Bange-L’Eau-Morte karstic system using classical and original
techniques, recession curves, correlation and spectral analyses, noise analysis and wavelet analyses. The main characteristics that can
be deduced are the recession coefficients, the dynamic volume of storage, the response time of the system, the quickflow and baseflow
components and the snowmelt characteristics. The non-stationary and timescale-dependent behaviour of the system is studied and particular
features of the runoff are shown. The step-by-step use of these different techniques provides a general methodology applicable to different
karstic systems to provide quantifiable and objective criteria for differentiation and comparison of karstic systems.
