Geotop: a standard in 3D land subsidence studies in The Netherlands

K. Koster, J. Stafleu, D. Maijers, M.J. van der Meulen, Geotechniek special Land Subsidence, maart 2020, pagina 5

The Geological Survey of the Netherlands maps the Dutch subsurface systematically in 3D. Here the development of GeoTop is outlined, its recent application in subsidence studies, and its use under a newly implemented key register of the subsurface. Implementation of GeoTOP in the key register enables governmental stakeholders to make the right subsidence-related decisions. Volledige artikel


Monitoring shallow subsidence in cultivated peatlands

S. van Asselen, G. Erkens, Geotechniek special Land Subsidence, maart 2020, pagina 8

To develop a land subsidence monitoring system for cultivated peatlands, four measuring techniques are applied in the northeastern part of the Netherlands, including spirit leveling, extensometry, LiDAR and InSAR. The desired monitoring system should be able to capture long-term spatial and temporal subsidence trends at mm-scale accuracy. Volledige artikel


Methodology for systematic assessment of damage to buildings due to groundwater lowering-induced subsidence in The Netherlands

S. Kok, A.L. Costa, M. Korff, Geotechniek special Land Subsidence, maart 2020, pagina 12

In this paper a modular methodology is proposed for the systematic assessment of two subsidence-related damage mechanisms to buildings: timber pile rot due to low ground water levels and differential settlement of buildings on shallow foundations. Volledige artikel


Use of monitoring data for dike strengthening project KIJK

M. de Koning, R.R. van Buuren, J.K. Haasnoot, Geotechniek special Land Subsidence, maart 2020, pagina 16

For the dike strengthening project Krachtige IJsseldijken Krimpenerwaard (KIJK) in the Netherlands, two studies have been undertaken for which monitoring data played an important role. The data is used to determine the amount of soil needed to balance the subsidence and to quantify the building settlement due to natural subsidence. Volledige artikel


Climate-proof planning. Solution for preventing the immense cost of subsidence damage to dwellings and infrastructure

W. Kooijman, Geotechniek special Land Subsidence, maart 2020, pagina 18

The Delta Plan on Spatial Adaptation (DRA) aims to make the Netherlands climate-proof en water-resilient. Spatial adaptation means changing the public realm so that it can cope with the effects of climate change. As part of the DRA Programme (DPRA), Fugro was commissioned to contribute to a study on active groundwater level management. So far, over a hundred climate-related effects have been identified, from the rotting of wooden piles to roads flooding. Volledige artikel
