 Semester Frühjahrssemester 2021 Dozierende M. Willmann, J. Jimenez-Martinez Periodizität jährlich wiederkehrende Veranstaltung Lehrsprache Englisch

 Kurzbeschreibung The course is based on the course 'Groundwater I' and is a prerequisite for a deeper understanding of groundwater flow and contaminant transport problems with a strong emphasis on numerical modeling. Lernziel The course should enable students to understand advanced concepts of groundwater flow and transport and to apply groundwater flow and transport modelling.the student should be able toa) formulate practical flow and contaminant transport problems.b) solve steady-state and transient flow and transport problems in 2 and 3 spatial dimensions using numerical codes based on the finite difference method and the finite element methods.c) solve simple inverse flow problems for parameter estimation given measurements.d) assess simple multiphase flow problems.e) assess spatial variability of parameters and use of stochastic techniques in this task.f) assess simple coupled reactive transport problems. Inhalt Introduction and basic flow and contaminant transport equation.Numerical solution of the 3D flow equation using the finite difference method.Numerical solution to the flow equation using the finite element equationNumerical solution to the transport equation using the finite difference method.Alternative methods for transport modeling like method of characteristics and the random walk method.Two-phase flow and Unsaturated flow problems.Spatial variability of parameters and its geostatistical representation -geostatistics and stochastic modelling.Reactive transport modelling.
