New Methods for Optimal Management of Karstic Aquifers: Case of Big Spring Missouri
To better study, exploit and manage Karstic aquifers, a new approach using systemic analysis is currently used by Ramboll Environ. This approach uses a different state of mind than the conventional hydrogeological approach and requires an abundant collection of continuous data - using transducers - of the various parameters that monitor the functioning of the karstic aquifer (discharges, water levels, rainfall). This approach involved the development of a set of methods and high-performance software to extract information from the collected data, to recognize the physical signatures that are responsible for it and thus, whatever the difficulty encountered, including non-linearities, characterize the dynamics of systems and predict their behaviours. These methods are called correlative and spectral analyses, continuous or discontinuous wavelet analyses, Rescaled Range Analysis, fractal or multifractal analyses and attractor analyses.
The application of these methods to Big Spring, Missouri allowed the establishment of an “Identity Card” of the spring, encompassing all information necessary for an optimal management of the spring.
