Multiresolution cross-analysis of rainfall rates and karstic spring runoffs, 2002, Labat D. , Ababou R. , Mangin A. ,
In order to quantify the quality of the rainfall/discharge relationship across time-scales, we propose the use of both orthogonal wavelet multiresolution analysis and cross-correlation analysis. By using the two techniques together, it is possible to show, scale-by-scale, the influence of the input to the system (rainfall) on the response (discharge) of the aquifer and also to relate these results to the internal structure of the aquifer and to the degree of organisation of the karst drainage. An application of this method to three Pyrenean karsts is also shown

Rainfall-runoff relations for karstic springs: multifractal analyses, 2002, Labat D. , Mangin A. , Ababou R. ,
Karstic watersheds appear as highly as non-linear and non-stationary systems. The behaviour of karstic springs has been previously studied using non-linear simulation methods (Volterra expansion) and non-stationary analyses methods based on wavelet transforms. The main issue of karstic spring behaviour consists of the presence and the identification of characteristic time-scales. In order to highlight more precisely the scale-properties of the rainfall-runoff relations for karstic springs, the multifractal analysis is introduced. These methods are applied daily and half-hourly rainfall rates and runoffs measured on a three French karstic springs located in the Pyrenees Mountains (Ariege, France): Aliou, Baget and Fontestorbes. They are characterised by a variable development of the drainage systems. We have at our disposal long and uninterrupted series of data over period of several years, which constitute a high quality bank data. Multifractal analyses of both daily and half-hourly rainfall rates and runoffs give evident a scale-dependant behaviour. Effectively, it highlights the presence of different multifractal processes at each sampling rate. Using a universal class of multifractal models based on cascade multiplicative processes, the identified multifractal sub-processes are characterised by the classical parameters alpha and C-1. All these results should lead to several improvements in karstic springflow simulation models. (C) 2002 Elsevier Science B.V. All rights reserved

Wavelet analysis of Late Holocene stalagmite records from Ortigosa Caves in Northern Spain, 2009, Muoz A. , Sen A. K. , Sancho C. , And Genty D.
We have deduced short-term climatic changes from millennial to annual scales from the study of laminae thickness and radiocarbon analysis of Holocene stalagmite records from two caves in Ortigosa de Cameros (Iberian Range, northern Spain). Speleothems are made up of dark compact laminae (DCL) and white porous laminae (WPL) of seasonal origin. Couplets seasonality is deduced from monitoring calcite laminae growth, drip water rates, and soil organic matter flushed into the caves. The thickness variations of the couplets are analyzed using a continuous wavelet transform and the various periodicities at interannual, decadal, multidecadal, and centennial scales are revealed from the wavelet power spectrum. The periodicities at decadal, multidecadal and centennial scales, with periods around 9.7, 10.4, 14, 16, 22, 43, 73, 83 and 180 years, are mainly related to solar activity. Among the interannual periodicities, oscillations around the 2.4-yr-period may be linked to the Quasi-Biennial Oscillation (QBO), whereas periods ranging from 4 to 7 years may be associated with the El Nin o-Southern Oscillation (ENSO) and/or the North Atlantic Oscillation (NAO).
