Flow characteristics of triple porosity components in karst aquifers

Permeability Dimension Travel Time Flow Mechanism Distribution
Matrix μm to mm Long Darcy law, laminar flow Continuous
Fracture 10 μm to 10 mm Intermediate Cube law, usually laminar flow Localized
Conduit > 10 mm Short Darcy-Weisbach, open channel and pipe flow, turbulent flow Localized
