RADONE: A Computer Code for Simulating Fast-Transient, One-Dimensional Hydrodynamic Conditions and Two-Layer Radionuclide Concentrations Including the Effect of Bed-Deposition in Controlled Rivers and Tidal Estuaries.

摘要

RADONE is a computer code for predicting the transient, one-dimensional transport of radionuclides in receiving water bodies. The model formulation considers the one-dimensional (cross-sectionally averaged) conservation of mass and momentum equations and the two coupled, depth-averaged radionuclide transport equations for the water layer and the bottom sediment layer. The coupling conditions incorporate bottom deposition and resuspension effects. The computer code uses a discrete-element method that offers variable river cross-section spacing, accurate representation of cross-sectional geometry, and numerical accuracy. A sample application is provided for the problem of hypothetical accidental releases and actual routine releases of radionuclides to the Hudson River.
