摘要：
The mathematical modeling of karst aquifers has been limited to black box models many times where the input (recharge) is related to the output (spring discharge) by using a transfer function from system theory and the spectral analysis of time series. These so-called black box models have a limited use because they do not provide information on the local spatial characteristics of the karst aquifer. In order to have a mathematical spatio-temporal model of the karst hydrogeology, several issues must be addressed, including a three-dimensional numeric model of the karst system, a spatial evaluation of recharge, and a consideration of the epikarst, karst depressions, fracture zones, thick vadose zones, and the simulation of conduit flow and karst spring discharge. All these characteristics have been taken into account in the Sierra de las Nieves karst aquifer in the Malaga province, Southern Spain. Furthermore, this aquifer has three hydrogeologic basins, with three main discharge points. It is concluded that spatially distributed karst models have following requirements: the integration of all the available information, the availability of speleologic cave mapping, the development of numerical karst system simulation methods and karst models of flow in the karst system. The problems encountered are discussed and the proposed solutions are described. © Springer-Verlag Berlin Heidelberg 2015.
