Van der Spek, J.E. (author), Bogaard, T.A. (author), Bakker, M. (author)Groundwater dynamics may play a significant role in landslides. A detailed model is developed of the groundwater dynamics in landslides in varved clays in the Trieves area in the French Alps. The varved clays consist of a sequence of alternating silt and clay layers, covered by a colluvium layer and intersected by fissures. The hydraulic...journal article 2013

(author)WTP Gruszczyn supplies drinking water to a part of the city of Pozna?, in the Midwest of Poland. The conventional production flow control and pressure control of the facility was replaced by the advanced control software called OPIR. To assess the differences between conventional and advanced control, production flows and pressures of two...conference paper 2013

(author)WTP Gruszczyn supplies drinking water to a part of the city of Pozna?, in the Midwest of Poland. For the optimal automatic pressure control of the clear water pumping station, nine pressure measuring points were installed in the distribution network, and an active pressure control model was developed and installed. This model is a hybrid form of...conference paper 2013

Bakker, M. (author)Het drinkwater wordt vanaf de waterzuiveringen naar de onze huizen en bedrijven verpompt via de distributie netwerken. Deze netwerken zijn zeer uitgebreide systemen: naast elke straat en naast veel wegen en door veel weilanden liggen leidingen waardoor het water stroomt. De leeftijd van deze leidingen is divers: in jonge steden of in nieuwe...conference paper 2013

Bakker, M. (author), Vreeburg, J.H.G. (author), Van der Roer, M. (author), Sperber, V. (author)An algorithm which compares measured and predicted water demands to detect pipe bursts was developed and tested on three data sets of water demand and reported pipe bursts of three years. The algorithm proved to be able to detect bursts where the water loss exceeds 30% of the average water demand in the area. The accuracy depends on the...conference paper 2012

Bakker, M. (author), Lapikas, T. (author), Tangena, B.H. (author), Vreeburg, J.H.G. (author)Water supply systems are vulnerable to damage caused by unintended or intended human actions, or due to aging of the system. In order to minimize the damages and the inconvenience for the customers, a software tool was developed to detect anomalies at an early stage, and to support the responsible staff in taking the right decisions to restore...conference paper 2012

Bakker, M. (author)A new analytic-element solution is presented for a well with a sinusoidal discharge pumping near cylindrical inhomogeneities. Both the transmissivity and the storage coefficient may be different inside each cylinder. The solution consists of separate series solutions inside and outside each cylinder; asymptotic expansions are presented for cases...journal article 2009

Bakker, M. (author)A new accurate numerical solution is presented for aquifer storage and recovery (ASR) systems in coastal aquifers; flow is approximated as radial Dupuit interface flow. The radial velocities of points on the interface are a function of time, the vertical coordinate, and the dimensionless parameter D (the discharge of the well divided by the...journal article 2009

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...journal article 2008

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...journal article 2008

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...journal article 2006

Bakker, M. (author)Morphological development was researched along five meanders in the Allier river, France. This includes large scale development of meander form and direction and guiding factors and processes. On a smaller scale channel processes that form morphology, including bars and (secondary) channels. Five meanders in the Allier river, France,...report 2005
