| Abstract: | Conductive heat exchange between streambed and the water contacted is a significant heat balance component in a full thermal budget model, especially in ice covered rivers or shallow streams. A numerical model based upon a finite difference solution of the unsteady heat dispersion equation is formulated to predict heat conduction between water and streambed with emphasis on its application to the diurnal temperature variations of shallow or ice covered streams. |
