“…A simple karst unit exhibits a normal distribution on a probabilistic graph while its duration curve is presented by a straight line with a certain slope (Soulios 1985;1991). In complex karst units; overflow or discharge loses towards an adjacent unit, or a supplementary recharge results in the differentiation of the duration curve, i.e., the change of its inclination (Soulios 1985;1991).…”

The importance of the groundwater management of karst aquifers relatively to their complexity requires the knowledge of the subsurface flow and storage behavior. In this study, a methodological approach based on the exploitation of daily spring's discharge data was developed and tested. The methodology makes use of the hydrograph recession curves, the correlograms output, and the logarithmically structured duration curves. This methodological approach was applied to the complex karst system of Louros basin. The Louros karst system consists of individual karst units discharged by respective springs which are distributed on three levels and form three easily distinguishable groups. The application results revealed a well organized karst system with conduits of slow and fast flow. It also revealed the uniformity and the complexity of the different units, as well as the properties, such as the storativity and the evolutionary process. This approach demonstrates the benefits of interpreting different methods in a hydrologically meaningful way for the recharge data evaluation.

“…Recession coefficients that increase with time have been observed in southern France (Bailly-Comte et al, 2010), Greece (Soulios, 1991), the Dineric Karst (Mangin, 1975;Bonacci, 1987 and1993), and, recently, in northwest Arkansas. Three models have been proposed for recession coefficients that increase with time: 1) Spring basins with two lithologies of contrasting permeabilities, which creates a lag-time for the inflow of water to the spring orifice (Soulios, 1991), 2) changes in storageoutflow relations created by temporarily flooded cave passages or ponor retention ponds that are drained by smaller diameter conduits (Bonacci, 1987 and1993), and 3) water exchange and pressure transfer between the matrix and conduit when antecedent water levels in the aquifer matrix are medium to high compared to those of the conduits prior to rainfall (Bailly-Comte et al, 2010).…”

Bonacci (1987 and1993) proposed that when the water levels in a cave chamber or a ponor retention pond rise above the surrounding ground-water table in the aquifer, the capacity of the conduits draining these features is exceeded.…”

“…Other studies are based on the difference response separation method or on the analysis of transfer functions between input and output; the karst aquifer is considered to be a blackbox. Bonacci (1993) and Soulios (1991) and Kovács et al (2005) directly analysed the form of the whole discharge flow recession, which is influenced by the size and the hydrodynamic characteristics of the karst system. Other authors employed the hydrograph component separation with different models to obtain some information about the behaviour of the aquifer (e.g.…”

Abstract:The regional study of hydrodynamic characteristics of karstic aquifers is challenging because of the great variety of lithology and the structural complexity found in carbonate formations. In order to improve this situation, a combined approach of time series and stochastic analyses was adopted to assess the hydrodynamic behaviour of the karstic aquifers. To achieve this, daily flow rates of 20 springs were taken from the 11 most significant aquifer units of the Basque Country. The results demonstrate the presence of memory effects, which modulated the input rainfall for short-, medium-and long-term storage capacity, resulting in hydrodynamic properties such as system memory, response time and mean delay between input and output. They reflect the storage and the manner in which these are filled and emptied, thus indicating the karstification of the aquifer. Likewise, the hydrodynamic and hydraulic classification obtained from the stochastic analysis provides a complementary approach to characterize the hydraulic behaviour of the studied karstic aquifers. The discussed examples indicate that this approach provides an excellent method to research hydrological karst systems. It is also shown that the use of hydrologic time series, alone, does not lead to a satisfactory classification of the hydrodynamic characteristics. Therefore, the general approach to hydrological regionalization in karst areas should take into account the structural complexity, heterogeneity of the lithology and the degree of karstification. Only in this case will the regionalization be physically founded, leading to a regional understanding of the hydrodynamic characteristics and flow conditions in a karst aquifer.
