 Student already contribute a number of years to our projects on fresh and salt groundwater in the coastal area. Sometimes with nice reports, sometimes with great results, article worthy! As such, this made that we are a strong supporter of guiding students through internships or thesises (both MSc and PhD)! We have already had students from Dutch universities (WUR, UU, VU), Universities of Applied Sciences (Zeeland, Larensteijn) and institutions like UNESCO-IHE. Foreign (PhD) students were welcome (Universities of Ghent, Florence, Bologna, Rome (La Sapienza)).

We have quite a few new topics, from numerical modeling to water system analysis using monitoring techniques. Just contact us, or the students below. Till hears!

New topics:

• Feasibility Study The Coastal Collector
• Vulnerability Study: Upscaling rainwater lenses throughout the Southwestern Delta:
• Research on salinisation processes in the Brabant Delta: causes (deep) hydraulic head decline in North Brabant salinization?
• Modeling of submarine groundwater discharge along an extended coastal stretch
• 3D Modelling salt water intrusion in the Bengal area

Course Groundwater in the coastal zone

18-20 September 2014, Delft – The Netherlands

download flyer for detailed information

| | !

Description:

The course will provide participants with (1) principles and procedures of variable density groundwater flow and coupled solute transport, (2) salinisation of groundwater systems and fresh-saline groundwater flow phenomena in the coastal zone, (3) monitoring techniques for fresh-brackish-saline water systems and (4) modelling experiences through hands-on training in computer workshops. On completion of this course the participants are able to understand, quantify and monitor groundwater flow processes in the coastal zone and to construct some (relatively simple) models on variable density groundwater flow and coupled salt transport. A fi eld visit to the south-western part of the Netherlands will provide participants some field experiences in handling monitoring techniques to understand fresh-saline groundwater systems.

The following persons participate in the fresh-salt research on this wiki:
