Aims

The aims of the course are to:

• This module aims to provide an in-depth look at pollutant transport in water bodies (surface and groundwater) and in the ground, their transport mechanisms and associated risk assessments and available remedial strategies.
• The module is divided into two halves: the first half will address ground and groundwater contamination,
• the second half will address pollutant and sediment transport in surface water.

Objectives

As specific objectives, by the end of the course students should be able to:

• Develop an appreciation of current and future problems and legislations related to contaminated land and waste containment;
• Understand the advective, diffusive, dispersive, reactive and sorptive processes related to pollutant transports
• Develop good understand of contaminated land remediation options and selection decisions;
• Develop an understanding of decision support tools for contaminated land management;
• Appreciate the crucial stages in dealing with and managing contaminated land;
• Estimate the mixing coefficients in uniform open channel flows;
• Understand the mechanism of soil particle motion subject to surface water flow;
• Calculate the sediment transport rate and determine the bed regime;
• Appreciate the interplay between sediment transport and pollutant transport.
