Abstract
A set of equations was derived to model the dynamics of the thermal advection/diffusion processes that are caused by the discharge of stormwater effluent into a water body. This model will be used to predict the size, temperature, and duration of the region of a water body that exceeds a temperature limit due to the discharge of urban stormwater runoff. The mixing zone was divided into two regions, ambient and heated, separated by a moving isotherm defined by a threshold temperature limit for the water body. The motion of the isotherm is governed by the net heat flux at the boundary surface. This is similar to a Stefan condition but the parameters were extended to include the heat fluxes at the boundary due to advection.
