The numerical analysis of conservative inclined plumes using the k-ε turbulence model is carried out. The basic differentical equations are discretized by the SIMPLE method. The standard values of the constants in the k-ε turbulence model are used. The variations of the travel speed, the maximum height of a plume front are obtained from numerical solusions. The agreement of numerical results and expereimental ones for the travel speed and the maximum height is generally well. The contours of salinity concentration and velocity vectors of an inclined plume front for nine cases are also obtained and show the flow mechanism in a inclined plume clearly.
