Ekkamol Vannametee or Top is a PhD student at Earth surface hydrology group, UtrechtUniversity. His research topic is entitled, ‘Nested discharge modelling from the large catchments using hydro-geomorphologic units’. The research goal is to develop a semi-distributed modelling framework for large-scale catchments based on the Representative Elementary Watershed (REW) concept. His research has two main parts. The first part focuses on the identification of a lumped physically-based process conceptualization (i.e. closure relations) for surface runoff fluxes at the REW scale that takes into account the scaling effects and uses observed physical properties of REW at a point-scale . The model performance is evaluated against the field data from a test catchment (12 km2) in French Alps. To extend the modelling framework for large-scale application, the second task is to develop a generic algorithm for the automated derivation of the modelling units (i.e. hydro-geomorphologic units) using Mulitiple Point Geostatistics. Accuracy of the automated map is assessed using both the geomorphology field map and a hydrological model. Effects of errors and uncertainties in the automated delineation of modelling units to the hydrological predictions will be also investigated.
Top received his BA in Geography (2003) fromChulalongkorn University,Thailand. In 2004, he was awarded a scholarship from Anadamahidol foundation under the royal patronage of HM the King of Thailand to peruse the graduate study aboard. He attended the master programme in Physical Geography atUtrechtUniversityin 2005. His MSc thesis was on the hydrological scaling of Hortonian runoff processes for an alluvial fan as a fundamental knowledge for geomorphology-based catchment modelling. During his master study, he has also spent 5 months working at Joint Research Centre (JRC),Ispra,Italy, where he investigated the use of MODIS snow cover products and data assimilation to improve the LISFlood model performance. After his graduation in 2008, he became a PhD student at Department of Physical Geography,UtrechtUniversity. His PhD research topic is basically a continuation of his master thesis.
