30 DELTARES, FEBRUARY 2016
Climate adaptation, energy supplies,
communications, transportation and de-
fence have at least one thing in common:
decisions are taken in extremely uncertain
conditions. This emerged during the third
international workshop Decision Making
under Deep Uncertainty, which brought
together more than ninety scientists and
experts from around the world. Because it
has been applied in several domains, the
discipline of decision-making in deep un-
certainty has developed rapidly. To keep
each other informed about developments
in the interim, it was decided to establish
a society.

YOUNG DELTARES EXPERTS
WRITE BEST PAPER
Pepin van der Ven, Greta van Velzen,
Tom O'Mahoney and Alexander
de Loor won the PIANC Young
Professional Best Paper Award with
their paper Comparison of Scale
Model Measurements and 3D CFD
Simulations of Loss Coešcients
and Flow Patterns for Lock Levelling
Systems. Their study showed that
the computational fluid dynamics
method can be used to determine
the discharge coe¨cient for a new
lock design. The jury was impressed
by the practical applicability of
the study, which makes the use of
expensive scale models redundant,
or allows them to be used more
e£ectively.
Two Dutch ministers - Henk Kamp (Economic A£airs) and
Melanie Schultz van Haegen (Infrastructure and Environment)
- o¨cially opened the new Delta Flume, quite literally with a
splash. They experienced first-hand that the Delta Flume does
indeed produce the highest man-made waves in the world. The
Delta Flume is used to study coastal protection, natural flood
defences and block revetments in infrastructure.The
research results will help to develop solutions to com-
plex climate challenges in delta areas throughout the
world. See the simulated wave by clicking on this link:
