On subsurface stormflow: Predictions with simple kinematic theory for saturated and unsaturated flows

This paper provides analytical solutions for some simple cases of subsurface stormflow. The solutions are based on kinematic approximations in both unsaturated and saturated zones. Solutions for rising, falling, and partial equilibrium hydrographs are given. The analytical model has been applied to data collected on a hillslope of the East Twin Brook catchment, Mendip, United Kingdom. Measured and predicted hillslope hydrographs were in good agreement.
