PhD in Modelling Spatial Grain-Size Variation & Residual Sedi

The Geotechnology Department comprises four sections: Applied Geology, Applied Geophysics and Petrophysics, Geo Engineering, and Petroleum Engineering. Its research activities are strongly interdisciplinary and aimed at the development and dissemination of innovative, integrated geo-technologies in the fields of subsurfaceimaging, characterisation and engineering for cost-effective andsustainable utilisation of the subsurface.

The Section of Applied Geology aims to develop high-resolutionquan titative models of geological heterogeneity in clastic sedimentarybasins at different spatial scales. The models serve to enhance ourunderstanding of clastic sedimentary systems as a whole, and will beapplied in the discovery, use and sustainable management of
subsurfaceresources . We strive to reduce the inherent uncertainty in numerical modelling by developing tools for quantitative prediction of keysubsurface properties such as size, shape, spatial distribution andinternal heterogeneity of sediment bodies.

JOB DESCRIPTION
Sediment grain-size data are routinely collected in many geoscientificsurvey s. In addition, estimates of sediment grain size may be derivedfrom other measurements collected during surveys (`proxies'). Theinformation contained in such data may be used to build subsurfacemodels for resource estimation, hydrological analysis, and hydrocarbonproducti on. The first objective of this research project is to build a(geo)statistical toolbox comprising a set of Matlab scripts designed tobe used by non-specialists. The toolbox includes: 1) estimation ofgrain-size parameters from proxy data; 2) reconstruction andinterpolation of continuous particle-size distributions from discretemeasurement s; 3) geostatistical modelling of spatial variation ingrain-size distributions (2-D and 3-D). Further research shall becarried out to 1) develop a method for extraction of residual sedimenttransport fields from spatial patterns of grain-size variability; 2)compare inferred residual transport fields to morphological data sets,and conduct process-based simulations of sediment transport andmorphodynamics. REQUIREMENTSCand idates should have an MSc in Earth Sciences(Geology, Geophysics, Physical Geography) or Civil Engineering( Engineering Geology, Hydraulic Engineering, Petroleum Engineering) . Wespecifically invite applications from candidates with demonstrableexperie nce in one or more of the following fields: (geo)statisticalmod elling, computer programming (e.g. Matlab) and
modelling of sedimenttransport/ morphodynamics.

CONDITIONS OF EMPLOYMENT
The successful candidate will beemployed by Delft University of Technology for a fixed period of fouryears within which he/she is expected to write a doctoral thesis.

TU Delft offers an attractive benefits package, including a flexiblework week, free high-speed Internet access from home, and the option ofassembling a customized compensation and benefits package (the 'IKA').Salary and benefits are in accordance with the Collective LabourAgreement for Dutch Universities.

Delft University of Technology strives to increase the number of womenin higher academic positions; women are therefore especially encouragedto apply.

APPLICATION
To apply, please send a detailed CV along with a letter of application by 15 April, 2009 to: recruitment- citg@tudelft. nl .
