Groundwater flow through anisotropic fault zones in multiaquifer systems

Anderson, E.I. (author), Bakker, M. (author)

Vertical faults through the shallow crust are commonly believed to act as either barriers to horizontal groundwater flow normal to the fault, conduits to horizontal flow tangential to the fault, or a combination of both. In addition, enhanced vertical permeability has been identified as a common feature. We investigate the effects of vertical...

Calibration of transient groundwater models using time series analysis and moment matching

Bakker, M. (author), Maas, K. (author), Von Asmuth, J.R. (author)

A comprehensive and efficient approach is presented for the calibration of transient groundwater models. The approach starts with the time series analysis of the measured heads in observation wells using all active stresses as input series, which may include rainfall, evaporation, surface water levels, and pumping. The time series analysis...

Ten Years of bored tunnels in the Netherlands: Part I: Geotechnical issues

Bakker, K.J. (author), Bezuijen, A. (author)

Ten years have passed since in 1997 for the first time construction of bored tunnels in the Netherlands soft soil was undertaken. Before that date essentially only immersed tunnels and cut-and-cover tunnels were constructed in the Netherlands. The first two bored tunnels were Pilot Projects, the 2nd Heinenoord tunnel and the Botlek Rail tunnel....

Analytical solutions for whirling groundwater flow in two-dimensional heterogeneous anisotropic aquifers

Hemker, K. (author), Bakker, M. (author)

Analytical solutions are derived for steady state groundwater flow in a heterogeneous, anisotropic, semiconfined aquifer. The aquifer consists of a number of horizontal layers, while each layer consists of a number of homogeneous cells with different hydraulic conductivity tensors. An exact solution for an arbitrary number of layers and cells is...

Structural Design of Linings for Bored Tunnels in Soft Ground

Bakker, K.J. (author)

The increase of bored tunnels in the Netherlands has raised the question how to design the tunnel structure in an efficient way. As a large part of the cost of a bore tunnel is related to the cost of the lining, it is important to design the lining in a cost-effective way. In the Netherlands it is customary to base the structural design of...

Soil Retaining Structures: Development of models for structural analysis

Bakker, K.J. (author)

The topic of this thesis is the development of models for the structural analysis of soil retaining structures. The soil retaining structures being looked at are; block revetments, flexible retaining walls and bored tunnels in soft soil. Within this context typical structural behavior of these structures is discussed too. The emphasis within the...

Monitoring pilot projects on bored tunnelling: The Second Heinenoord Tunnel and the Botlek Rail Tunnel

Bakker, K.J. (author), De Boer, F. (author), Admiraal, J.B.M. (author), Van Jaarsveld, E.P. (author)

Two pilot projects for bored tunnelling in soft soil have been undertaken in the Netherlands. The monitoring was commissioned under the authority of the Centre for Underground Construction (COB). A description of the research related to the Second Heinenoord Tunnel and the Botlek Rail Tunnel will be given. The Second Heinenoord Tunnel has...

Coastal Dynamics

Bakker, W.T. (author)

This book deals on "Coastal Dynamics", which will be defined in a narrow sense as a mathematical theory, which starts from given equations of motion for the sediment, which leads with the continuity equation and given boundary conditions to a calculated (eventually schematized) coastal topography, which is generally a function of time. This is...

Op 6 en 7 oktober 1994 hebben twee grootschalige damdoorbraakexperimenten plaatsgevonden in Het Zwin in Zee uwsch-Vlaanderen. Vooral het eerste experiment op 6 oktober heeft veel publicitaire aandacht getrokkcn. Op het beslissende ogenblik, het begin van de proef rondom het tijdstip van hoogwater, verliep deze proef niet volgens verwachting. Het...

Effect of tidal resonance on the morphology of Wadden and Estuaries

Bakker, W.T. (author)

Contains basic paper plus background supplements. Areas like the Western Wadden area have a length of approximately 1/4 of a tidal wave length. Therefore tidal motion is sensible for resonance. It is investigated, under which circumstances morphological instabilities may occur. Instabilities are defined in this way, that small depth increments...

Coastal changes, caused by a shallow water sanddam in front of the Delfland coast

Bakker, W.T. (author), Delver, G. (author)

Along tht coastline at Ter Heijde, near Delft, a dam parallel to the coast in shallow water will be constructed havlng a horizontal crest at the level NAP -3 m on the landward side, merging into the existing coastal profile and having on the seaward side a slope 1:20. The dam will have a length of 1.5 km (fig. 1). This work will be carried out...
