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 thesis (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 Aachen, Ghent, Firenze, Bologna, Roma (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 via e.g. LinkedIn!

  |

New topics:

• Freshwater management techniques as a bridge between water demand and supply in the Mekong Delta, Vietnam (including fieldwork provinces Ben Tre or Tra Vinh)

• Analysis of upconing of saline groundwater under deltaic areas (numerical study)
• Effect of model parameters (e,g. solute solvers, grid convergence) on variable-density groundwater and salt transport benchmark cases (e.g. Henry, Hydrocoin, upconing; numerical analysis using iMOD-SEAWAT)
• Fresh groundwater resources management at a farmers level in the province of Zeeland, The Netherlands: setting up robust web-based clipping tools; a modelling study
• Assessing submarine groundwater discharge along coastal stretches: a global analysis
• Setting up a 3D variable-density groundwater flow model simulating salt water intrusion in a deltaic area: possible cases: the Bengal, Indus, Po, Yangtze, Pearl river deltas

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.
