GEOTECHNICS IN CHANGING CLIMATE
GEOTECHNICS IN CHANGING CLIMATE
(OP)
Dear Readers,
Climate change is one the burning issues in this centrury.
How shall be think about adoption of the chaning climate in geotechnical practice? Why geohazards have increased due to changing climate? or is it simply a fuss for us?
May be we should have this issue on table

RE: GEOTECHNICS IN CHANGING CLIMATE
The concept of "global warming" or climate change is really a very long term subject - thousands of years. The weather variations (wind, temperature, rain, snow, etc.) are limited to the history of past records and most construction is based on the tradition and performance under the recorded conditions. Granted, the short term history has degraded some weather effects from 100 year storms to 50 year storms, but this can be handled easily with professional judgement.
There have been some dramatic (but really minor) occurances in the past 5000 years. - The mini ice age in the Middle ages, etc.
I would be more concerned with the geological(stability, seismic, etc.) factors for most structures since the climatic variation are less important and do not an major effect on a structure.

We have a few evidence that certain part of the area is experiencing highest water level ever measured and and some other palces where the ground water layer is rapidly decreasing with more than 15 cm each year! With respect to climate change I am more worried about the frequency of natural disasters which has increased ten fold in past few years.

-loss of foundation support due to thawing permafrost
(that connection may be impossible to prove, but there some designs were modified due to concerns the permafrost may be warming)
-increased coastal erosion due to less sea ice. Supposedly wave action has been more severe than in the past without the sea ice to mitigate the storm's effect.
