Salt water intrusion of bank groundwater from rivers

A substantial percentage of drinking water in the Netherlands is obtained as bank groundwater by pumping stations alongside rivers. Rising sea levels and lower river discharges caused by longer droughts and upstream water and groundwater use causes the salt water wedge to penetrate further upstream salinizing the river from time to time, especially near its bottom, thus causing intrusion of salt into the groundwater and affecting nearby drinking water wells. This situation was simulated in a cross section for a pumping station near Ridderker in the Netherlands to show what may happen. The exercise was carried out by Remko Nijzink, in preparation for his Geo2 exam at TUDelft, June 2011.

Building Envelope Design Guide APEGBC

The Building Enclosure Design Guide — Wood-Frame Multi-Unit Residential Buildings updates earlier best practice guides that have been instrumental in creating a consistent approach to the design and construction of effective building envelopes. This current Guide builds on previous work, including earlier editions published by the Canada Mortgage and Housing Corporation (CMHC), and industry knowledge gained over the last decade: The Guide was developed by the Province in partnership with the Homeowner Protection Office (HPO) and in collaboration with an industry task group. The Association of Professional Engineers and Geoscientists of BC (APEGBC) and the Architectural Institute of BC (AIBC) have endorsed the publication as an invaluable reference for the construction industry.
