## FLOWER: a computer code for simulating three-dimensional flow, temperature, and salinity conditions in rivers, estuaries, and coastal regions

FLOWER is a three-dimensional computer code for simulating fast-transient, free-surface flow, temperature, and salinity conditions in rivers, estuaries, and coastal regions. The model also includes rotational effects (Coriolis force) and is capable of accommodating wind-stress coupling, a capability which enables the model to be applied to large water bodies with significant wind-driven currents, such as the Great Lakes. The mathematical formulation utilizes the integral form of the governing equations of the discrete-element method. In this method, interior flow regions are represented as rectangular elements of variable size, while impermeable boundary elements are constructed from truncated rectangles, thus allowing accurate representationsmore »
