•Simplified models that reproduce karst spring hydrographs for free-surface flow conditions.•Karst aquifer characterization using effective discharge expressions.•Application on actual karst aquifer systems. Most karst aquifers are characterized as a dual-flow system comprised of a highly conductive...
