Karst aquifers are very important groundwater resources around the world as well as in coastal part of Croatia. They consist of extremely complex structure defining by triple phases: slow porous medium, mostly laminar fractures and usually fast turbulent conduits/karst channels. Usually, karst aquifers have been analyzed by lumped hydrological models which ignore high heterogeneity of karst and consider only input (precipitation) and output (spring discharge) due to lack of extensive other input data and knowledge regarding the karst system. Last two decades full hydraulic (distributive) models have been developed exclusively by conventional finite elements considering karst heterogeneity structure that improves our understanding of complex processes in karst. Therefore, in this project we will develop novel “unique” flow model based on multi-resolution approach originally designed by Gotovac et al. (2007-2013) for 1-D and 2-D groundwater flow and transport simulations. Proposed approach is based on Fup basis functions with compact support and meshless collocation procedure enabling multi-scale representation of heterogeneity and other flow variables, closely related to the karst flow physical interpretation. Moreover, extending existing procedure to 3-D and constructing separate multi-scale solution for all three karst phases, proposed approach will enable the following impacts in comparison to conventional methods: desired spatial and temporal accuracy and high computational efficiency, modular model structure, incorporation of different heterogeneity scales related to existing measurements, enabling of transport and tracer test analysis and better understanding of karst aquifers due to solving of different engineering problems such as water usage and protection or contaminant pollution. Flow model will be verified by laboratory experiments and numerical synthetic benchmarks as well as real examples such as Jadro catchment and Ombla underground accumulation.
