Assessment

Edit Assessments Content
The windrose, gaussian plume modelling, soil profile/hydrology and groundwater contamination assignments will provide the modelling skills required for the solid waste project. During the workshops, you will also have time to work on the solid waste project and get advice and feedback from the demonstrators.
