  4. Transient Flow Through Chemically Interactive Porous Sediments Dr. Ir. Amro Elfeki Section Hydrology and Ecology, Dept. of Water Management TU Delft

  5. Research Directions and Collaborations • Heterogeneity Modelling and Uncertainty by Coupled Markov Chains (CMC): -2D CMC: Elfeki (CiTG) and Dekking (EEMC). -3D CMC: (2-years postodc NWO Project: Park, Elfeki, Dekking. • Transient Flow and Transport Modelling: - Gradient Magnitude Variability: MSc. thesis (Lebreton, Elfeki and Uffink). - Gradient Direction Variability: (not yet). • Modelling Chemical Interaction with • Porous Sediments: 2-State PTRW method: (Elfeki, Bruining, Dekking, Kraaikamp and Uffink)

  6. Research Output • Heterogeneity Modelling and Uncertainty : - 2D CMC: Article in review (Elfeki and Dekking). -2D CMC uncertainty: Article in preparation (Elfeki and Dekking). - 3D CMC: Article published in UIST Conf. Oct., 2003. (Park, Elfeki and Dekking) • Transient Groundwater Flow and Transport Modelling: -MSc. Thesis by Sophie Lebreton (Supervisors: Elfeki and Uffink). -Poster for the DIOC meeting Dec. 2003. -Article published at MEJ, March, 2003 (Elfeki). -Articles are foreseen from Sophie thesis. • Modelling Chemical Interaction with Porous Sediments: - Article in Preparation “Linear Adsorption” (Elfeki, Bruining, Dekking, Kraaikamp and Uffink). - Non-linear Adsorption Case.

  7. Influence of the period of Oscillation Head profiles along the aquifer length. T he downstream water level is a cosine function with an amplitude of 5m and with different periods: 1, 5, 10 days. The length of the aquifer is 300m, the storativity S=0.01. Penetration length : controls the propagation of oscillations within the aquifer. When the period P increases, the penetration length increases

  8. Geological Uncertainty Quantification by CMC Data 19 boreholes Stochastic simulation of the longitudinal Section of afsluitdijk-Caspar de Roblesdijk, a part of Waddenzeedijken conditioned on 13 boreholes. Simulation conditioned on 13 boreholes

  9. Modelling Chemical Interaction with Porous Sediments: Non-linear Adsorption
