Doctorate in laboratory study of subglacial drainage
Subglacial water flow plays a pivotal role in glacier dynamics via impacting sliding speeds, erosion rates, and glacier lake drainages. However, the decade-old theories of subglacial drainage remain only weakly tested as direct observations are difficult. The avenue of testing these theories in laboratory experiments remains largely unexplored.
Our institute, the Laboratory of Hydraulics, Hydrology and Glaciology (VAW), has both a long-standing expertise in subglacial drainage studies as well as a world renown hydraulics laboratory. This project aims to combine those two fields of expertise to investigate subglacial drainage in a laboratory setting. A novel flume experiment will be constructed and used to simulate the subglacial conditions.
The project aims at simulating the hydraulics, sediment transport, and till dynamics in a setting designed to mimic the subglacial environment of a till-bedded glacier. With the experiments you will test existing theories of so-called canal drainage. A particular focus will be on canal inception, steady states, till dynamics, and whether a canal drainage system is distributed or channelised.
To achieve these measurements you will design and construct a novel type of flume allowing for pressurised water flow and till compression.
The starting date is negotiable, the latest start being envisioned for 1 September 2020.
The planned project duration is 3.5 years.
