Most industrial pollution sources are stacks with discharges of momentum and heat as well as pollutants. The resulting plume rise can be considerable—hundreds of meters—and can substantially aid the dilution of plume constituents before they reach ground level. Thus, plume rise is an important factor to consider in diffusion modeling. For power plants and other moderate-to-large industrial sources, the major contribution to the rise is from the heat flux. For example, a modern power plant typically discharges ~ 100 MW of heat from its stack. Source momentum can be important for smaller sources, such as those typically found in light manufacturing. Although we will address the plume rise due to source momentum, we will give most attention to the effects of source buoyancy.
