Diffuse-flow networks in karst aquifers include integrated fracture systems in bedrock and intergranular pores in regolith and unconsolidated cave fill. The size, distribution, tortuosity, and interconnection of voids in fractured rock or unconsolidated material determine how readily water will move through diffuse-flow …

Laminar flow is a gentle flow in which the streamlines are not crossing each other, that is, they are parallel to one another. What determines a flow if it is laminar in nature or not is the value of its Reynolds number, if the Reynolds number is less than 2000, the flow is still con-sidered to be laminar flow. The laminar flow still re- c. Contour plowing. 9.
