LAG AND TRANSFER TIME INFERRED FROM MELTING CYCLES RECORD IN THE COULOMP KARST SPRING (ALPES DE HAUTE-PROVENCE, FRANCE)
Abstract:

 

A 11-days long period of snowmelt cycles was selected from the discharge and temperature data collected at Coulomp spring (Alpes de Haute-Provence, France), which is the largest of French Southern Alps with a discharge of 1 m3/s. Its catchment is 30–50 km2-large and mainly composed of marly limestones and poorly permeable covers, responsible of a combined diffuse and concentrated recharge. From Q data we extracted snowmelt discharge (Snowmelt Q = oscillating part of the discharge) and Basal Q. The contribution of Snowmelt Q is 30–50 % of Q. Amplitude of spring temperature (Tspring) is about 2 °C due to alternation of cold snowmelt water with low residence time and “warm” phreatic water with longer residence time. The lag between the peak of air temperature (Tair) corresponding to the maximum of snow melting and the peaks of Q, corresponding to the transfer time between surface and spring, is less than 10 h. This 10 h transfer time combines about 7 h of vertical transfer through the vadose zone and 3 h of horizontal transfer through the drain.
