Abstract: A model is developed to predict the trajectory of a surface buoyant discharge into a large receiving water body. A Lagrangian approach is used to trace the path of a `control volume' of spreading fluid. The governing equations include effects due to buoyancy, entrainment, cross flow, wind, bottom drag and Coriolis acceleration. Spreading is calculated based on a `convective regime' assumption. The sensitivity of various parameters is investigated by a systematic variation of parameters. Model predictions are compared with previous model predictions of experimental data.
