Inverse Infiltration Modeling of Dike Covers Made of Dredged Material Using PEST and AMALGAM

چکیده
A variety of studies recently proved the applicability different dried, fine-grained dredged materials as replacement material for erosion-resistant sea dike covers. In Rostock, Germany, a large-scale field experiment was conducted, in which were tested with regard to installation technology, stability, turf development, infiltration, and erosion resistance. The infiltration experiments study development seepage line body showed unexpected measurement results. Due high complexity problem, standard geo-hydraulic models be unable analyze these Therefore, methods inverse modeling applied, such parameter estimation tool (PEST) AMALGAM algorithm. paper, two approaches are compared discussed. sensitivity analysis presumption non-linear model behavior problem Eigenvalue ratio indicates that is an ill-posed problem. Although this complicates (e.g., termination local minima), sets close optimum found both PEST algorithms. Together data, information supports rating effective properties applied used cover material.
