Opis

This thesis presents the development a generic morphological model for both structured and unstructured grid. An online coupling model frame is set up by modularizing a proven 3d hydrodynamic module, a bed state description module, a sediment transport module, a bed update module, and a vegetation population dynamic module. Since the model is embedded in the validated Delft software system, the existing hydrodynamics, water quality and bio-chemistry processes are applicable with minimum efforts in addition. Both relevant geomorphological and ecological processes and their scales are discussed. For the morphological model, numerical algorithms are adjusted to adapt unstructured grid. An adaptable bed update algorithm and corresponding numerical schemes are analysed. Mass conservation of morphological updating is discussed. Afterwards a generic velocity integration algorithm is presented.

O autorze

Qinghua YE (Wuxue, China,1977) studied Coastal Engineering at the Hangzhou University (now Zhejiang University) from 1994 to 1998 and graduated with first class honours (cum laude). From 1998 to 2001, he studied and graduated as an Msc in specialization of Coastal Engineering in Nanjing Hydraulic Research Institute. From 2001 to 2004, he worked as a coastal engineer in the section of River and Harbour department in Nanjing Hydraulic Research Institute. In 2004 he travelled to Delft, the Netherlands to study Hydroinformatics in UNESCO-IHE and was awarded a 2nd Msc in 2006. In 2006, he started to persue his phd in Delft hydraulics (now Deltares). From September of 2010 till now he was employed by Deltares as a consultant and researcher, first in the Hydraulic Engineering unit and later in the Deltares software centre. His main research interests include: process-based morphology modeling; sand bank/ridge generation and evolution; stability analysis; biogeomorphology; human interference (dredging, sand mining), river meandering; bifurcation; bank erosion; bed form evolution; vegetation effects, sediment /mud transport modelling and water quality modelling. He is also a Microsoft certified software developer in C++ and C#, a Sun certified Java programmer and a Cisco certified network associate
