20801644 - WATER QUALITY MANAGEMENT

The main scope of the Water Quality Management course is to provide students with the basic knowledge of the physical and biogeochemical mechanisms controlling the quality of groundwater (flow and contaminant transport modeling in groundwater). Furthermore the course addresses the assessment of contamination level, health risk and groundwater remediation systems.
Water Quality Management course is part of the master's degree program in "Civil Engineering for Protection from Natural Risks", whose objective is to train civil engineers with high professional qualifications for the protection from hydrogeological and seismic risks.
Within the framework of this course, the course aims to provide an in-depth knowledge of 1) flood legislation; 2) contamination sources in natural and anthropic environments; 3) main physical mechanisms of contaminant transport in groundwater and soils; 4) modelling of solute transport in environmental systems most popular computational tools flow and transport modeling in groundwater; 5) health risk due to contaminated groundwater; 6) main groundwater remediation systems.
Upon successful completion of the course, students will be able to 1) identify fundamental criteria and restrictions for the assessment of the environmental concentration and the related health risk ; 2) develop an hydrological/hydraulic model for the study of a contaminated site; 3) perform simulations exploring different contamination scenarios; 4) identify the most appropriate solution for groundwater remediation; 6) prepare project report and drawings.
