ABSTRACT
The use of materials that contain radioactive substances has gained grounds in Ghana due
to numerous benefits derived from them. These radioactive materials can be found in the
areas of medicine, agriculture and industries such as mining. Though there are strict
measures to ensure such material do not find its way into the environment, improper
management of the waste poses a threat to the environment. To be able to understand the
impact the radioactive material has on the environment, mathematical models play a very
relevant role in tracking the level of pollution in any medium. This thesis was concerned
with the numerical modelling for the transport of the radioactive solute material that
suspends in a stream using Matlab at different velocities as a result of flooding or an
accident for research purposes. The modelling was done by using partial differential
equations describing relevant physical processes evolution which includes water level,
dissolved and suspended substances concentration and velocities. The equation system
basis are the mass conservation and momentum laws, state equation and state transport
equations. The implicit finite difference scheme was used to evaluate the transport
equation, Advection-Dispersion Equation (ADE) with respect to time and space. Solution
algorithms for Matlab programming were developed and implemented for generating
results for analysis. The results obtained showed that the model was able to simulate
accurately the various levels of suspended radioactive sediment concentration changes in
the flowing stream longitudinally.
