Properties Affecting Karst Conduit Hyporheic Flow
Abstract
We present computational fluid dynamics simulations of wall morphology driven hyporheic flow in the permeable rock at the margin of a phreatic karst conduit. The simulations examine the effect on karst conduit hyporheic flow of different water and rock properties such as: turbulent flow in the conduit, wall morphology, and matrix rock permeability. Using information gained from the simulations, we present a discussion on controls of karst conduit hyporheic flow. Lessons learned have applications to hyporheic flow in surface streams including bedrock streams and streams with thin sediment overlying bedrock.
