Although it was already included in the November
newsletter, on 20 April it will become a fact - Delft Cluster AIO
(research assistant) Victor Beumer will graduate with his doctorate
thesis ‘Winter flooding in Dutch stream valley floodplains:
biogeochemical effects and vegetation consequences’. The graduation
ceremony is at 10.30 in the Academiegebouw in Utrecht (Domplein).
Doctorate supervisor: Prof dr Jos Verhoeven (UU); fellow doctorate
supervisors: dr Jasper Griffioen (DLT), dr Geert van Wiirdum (DLT) and
dr ir Boudewijn Beltman (UU). [Click

On Thursday 2 April,
Paul Hölscher gave a presentation at Parkeervak in Den Bosch
entitled ‘Geobrain Building Vibrations: A good start means half the
work’. His presentation described how to manage the risks involved with
a construction pit. It covered general tools as well as the following
aspects specific to building vibrations: the reliability of vibration
predictions, historical database of building vibrations, and surface
subsidence due to in- and out building vibrations of sheet piling. [Click

Experts from Delft
Cluster have shared their experiences of organising the fundamentals
for the structure of the IJsselmeer area with the Delta Water Award
team, whose plan is ‘Grevelingen: from lake to Delta’. This plan
describes how to once again create a Delta region from a lake area: a
safe environment with improved economy and nature. Following the flood
disaster of 1953, we firmly closed the doors with ‘hard’ defence
structures. As a result, a lake area was created and the Delta was
partly lost. By re-opening the door a crack, it will be possible to
restore the link between the sea, the Grevelingenmeer, and the Volkerak
within a period of 15 years. The plan will have a minimal impact on the
islands, and a maximum effect on a settled climate. Part of the plan is
for a car-free island along the coast that will offer recreational
possibilities and will guarantee a high level of safety. The experts
clearly place the emphasis on jointly reaching solutions with the
surroundings instead of simply enforcing solutions. In the plan, which
will eventually be put forward for the Delta Water Award, attention
will be given to organising the social and political foundations. Delft
Cluster will also make a film to portray the vision for this area,
which can then be used for dialogue with the surroundings. |

A great deal of consideration has already been
given to the IJsselmeer area over a number of years, both by various
government organisations including the former Department of Transport,
Public Works and Water Management-RIZA, the Ministry of Transport and
Public Works, and the Ministry of Agriculture and Food Standards, as
well as knowledge institutes such as Deltares. A broad social coalition
had also worked on a future vision for developing the IJmeer. However,
all attempts to gain a firm hold on the preferred future picture for
the IJsselmeer area have had their own limitations. As a result, work
is not carried out on an actual vision for the area: a future vision at
the level of scale of the entire IJsselmeer area; a vision that shows
both spatial as well as scientific-disciplinary cohesion and which is
carried out by those involved. The Wetlands Association therefore
took the initiative in the form of a broadly-based study into the
problems
|
of
the area, and in discussions with involved parties. The objective was
to bring about a discussion on the vision for the future, from the
viewpoint that a new attempt had to be made regarding the Zuiderzee
works. This is because trends and requirements are now apparent that
were unknown when the Zuiderzee works commenced 100 years ago. The
activities of the Wetlands Association are now coming to an end.
Wetlands will present its final report and a follow-on analysis to
important stakeholders’ representatives at a closing meeting in the
Muiderslot on 3 April.
