PRISE: Plume Rise and Dispersion ModelThe model PRISEd (Plume RISE) calculates all of the phases (rising, bending over the (quasi-) equilibrium dispersion) of the behaviour of the plume emitted by a stack in atmosphere or by a pipe in deep water, in one continuous formulation, taking fully into account the ambient meteorological (hydraulic) conditions.
The atmosphere is parametrised as consisting of two layers: a neutral layer with a lapse rate equal to the dry adiabatic and an overlying stable layer (extending to infinity). Three wind speed profiles are available: constant with height, logarithmic and logarithmic based on a user-input roughness length.
