Ecobeach
Proposal
POect
Subject
lntroduction
We
like
to
introduce
an
unsolicited proposal (USP) to
the
ministry of
environment
and the
coastal authority
for
Ecobeach
as a system for coastal protection of
a
part of the
west coast
of Jutland.
BAM is a construction company
which
is
established
in
the Netherland,
Belgium, Germany,
Denmark, lreland and
the
UK.
ln
some
niche markets
we
are
operating worldwide. The
turnover
of
BAM is 7,4 billion euro a
year.
BAM has
experience
in
marine works
and has
developed
research intensive products
for coastal
protection such as
the Xbloc.(see
www.xbloc.com
and
www.dmc.nl,
DMC
is
a
trade
name
of
BAM).
BAM
is
familiar with
the
PEM
system developed
by
mr
Poul
Jakobsen ( SIC). ln
the
Netherlands
BAM
has performed
a
test with
the
PEM
system
under
the
name
Ecobeach,
which
has been completed
two
years ago. A scientific contribution
-
peer
reviewed-
has
been presented at
the
ICE 2015 conference on
coastal management
in
Amsterdam. The
Ecobeach
test
and our
ongoing research
in
the
Netherlands
and Denmark gives
BAM
trust
in
the
performance of the
system
as
a
tool
for coastal
protection. For
more
information
we
like
to
refer to the
attachment
of
this
letter.
The
aim of
the
Danish
government
by the west
coast
protection
is
to
prevent
flooding
of the
hinterland due
to a
breach
in
the
dune system.
The
dunes have
to
resist
a
1:100 year storm.
The minimum
required dune
width
is
40
meters. One method
Kystdirektoratet
applies to
prevent
the
hinterland
from flooding,
is
to
establish
a
wide
and high
beach
in
front
of the
dunes.
Ecobeach provides
a
wide
and
high beach by
the
increase
of
beach volume,
a
stronger
beach by the
coarser
sand and growth of the
dunes.
Ecobeach
will
contribute to the
protection of the west coast.

Our USP consists at
first
of
the
installation
and
maintenance
of Ecobeach
over
55
km along
the west coast
of
Denmark. Secondly
our
USP consists of the intensive
-quarterly-
surveying
of the coast along the
55
km and additional analyses
to
monitor
the change
in
the
quality
of
the
sand.
ln
this
manner
we
are able
to
monítor
the
changes of
the beach after
installation.
Why
BAM
proposes
this
USP
Kystdirektoratet policy to assure safety
is
to establish
a
wide
and
high
beach
in
front
of the
dunes.
Ecobeach
fits
perfectly
in
that
safety
policy of
the
Danish
government
because it
provides
an
increase of
the
beach volume and a
stronger
beach
by
the
coarser sand.
BAM
trust
of the
system
is based on the
tests
and analyses over
the years
in Denmark
and
Netherlands.
Significant growth of
the
beach
in
the
Netherlands
Skodbjerge test site shows significant growth
after
placing
the
PEM/Ecobeach
system
in
the
period
2009-2014
Coarser sand (improved strength)
is
found on
Danish
and Dutch
Ecobeach test sites
After
removal
of
Ecobeach
in
the
Netherlands significant
decrease
of
the
beach
volume,
back to
the
50 year average value.
The
beach
sand
particle
size
in
the
test
area
returns to
the
average value along the coast
.
.
.
o
Kystdirektoratet refers often to
the Skodbjerge
PEM
evaluation
report of
2008
We
conclude
that
more
recent information;
the
measurements of
the
particle size of the sand and the
survey
data
up
to
2014 requires
a
reconsideration
of
the conclusions of the
2008
report.
We
have
also
made
a
comparison
of the
application of
nourishments in the coastal
management system of
the
Netherlands
and
Denmark. The
sand
resources for the
nourishments
in Denmark
consist
of
relatively fine
sand
(no contribution to a
stronger
beach
and
a
shorter
lifetime of
the
nourishment)
We
have noticed that
the
sand
nourishment
volume
in
Denmark
has been
much
less
in
comparison
to
the
Netherlands
despite
the
longer
length of
the
Danish
sandy
coast and exposure
to
higher
wave energies
.
USP:
governance
and
safety
ofthe
coast.

BAM likes
to
make
a
clear
statement; the governance and security of
the
Danish coast
is the
responsibility of
the
Danish authorities.
BAM reports to
the
Danish
authorities.
BAM has the
aim
to avoid
surprises. BAM
provides
an
early
warning system
by
the
high measuring frequency of
the
relevant
coastal
state
indicators.
ln all cases of emergency
the
Danish
authorities
have always
the
right
to take the
necessary
measures.
USP:
activities
For
this
proposal
BAM
has
obtained
permission
from
SIC to
apply Ecobeach in
Denmark.
We
propose
to
install Ecobeach over a stretch of 55 km along the
west coast
of
Jutland
for
a
period of
at
least five years. The system
will
be
installed
from Nymindegab to
Fjand
Our
proposal has been
changed
in comparison
to
the
2013 proposal,
in
order to offer
KDI the
opportunity to
assess
beach behaviour with and
without
Ecobeach
over longer
stretches.
After
installation BAM
will
maintain
the
system for
the contract
period.
USP:
analyses and reports
Ecobeach and the
quantity
of the sand on
the
beach
will
be monitored
on
a
frequent
basis.
The
beach
levelwill
be measured
4
times
a
year.
ln
our
USP we
will
monitor the quality
of
the sand.
We
continue
to
build
on
the
outcome of
our
Ecobeach research in
the Netherlands.
Before installation and
after
installation
with
a
yearly
frequency
the
sand
particle distribution
will
be
determined
along
the coastal stretch of
55 km. On
a
local
smaller
stretch the frequency
of
measurements of
the sand
particle
distribution
will
be
more
intensive.
The
outcome
will
be
the
relation
of
Ecobeach
with
the
change
in
the quality and quantity of the sand on
the
beach
.
Every year the
survey
results and analyses
will
be
presented
by
BAM to
KDI We
on
yearly
basis at least the following coastal
state indicators
:
actual dune
foot
position(
+4
m
line)
actual average beach height
in
front of the dune
foot
beach volume
the
change
in
the sand
particle
diameter
will
report
o
¡
o
o
On
basis of
the
monitoring results
further
research
will
be proposed.
USP:
success
of
Ecobeach.
The
yearly
results
of
Ecobeach
will
be
defined
in
comparison
with the
coastalcondition
at the
beginning of
the project
.
The evaluation
time
is before the
storm
season.
Success
of
Ecobeach
will
be defined
as:
the average dune
foot
position over
the 55
km is stable
or
the average
sand
quantity over
the
55
km
on
the
beach
60-80
m
in
front of the dune
foot
is
stable
ln
3
of
the
5
years
this performance
is achieved.
ln
the
last
condition
the effect of
storms
is
taken
into account. The first two
conditions
means
that on
a
local
spot
in
the 55
km the coast
can
recede or accumulate.
o
¡
.
lf
there
is
a success
the
project
shall
be
continued
for 5
more years and extended
to other
stretches of the coast.
The
details of the
evaluation
of
success
will
be
determined
later

During
our
maintenance activities we
will
adapt
the
Ecobeach
system
in
order to
optimise
the
system
ln case
of
no
success according to
the
BAM
definition
but success
to
Coastal
authority's
own
evaluation, we otfer also
the
possibility to continue
the
project
for 5 more
years.
Success
of
Ecobeach
will result
in
an
increase of the windblown
sand
drift on
the
beach to
the
dunes.
Measures to fix
the sand
in
the dune
zone are recommended,
but
excluded
in
our
proposal.
What we expect
from the coastal authorities in
Denmark
We
like to cooperate for
this
project
with
the coastal authorities
from the
start to finally the
evaluation of
the
project.
ln
this cooperation communication
is included.
We
have
the
intention to
tune
our communication to stakeholders
on the
coast
with
the
coastal
authority.
BAM propose to communicate
with
the coastal
authorities
on
a regular
base
during
the
5
years
of
the
project.
We
like
to
present and
discuss
our
evaluation
report(s) and the
results
of our
analyses
with
the coastal specialists of the authorities.
We trust and have assumed
that
BAM has the
opportunity to
use
the
survey
data/reports of
the coastal authority for
our
joint
analyse of the coast system.
Of course
we
like
to
receive permits by KDI for the application
of
Ecobeach.
The
permits shall
be in accordance with what
we
agree in our cooperation.
We
like
to
mention
that
in
the
Netherlands Rijkswaterstaat allows
the
application
of
Ecobeach on
the coast.
Before the start
of
the
project we expect all
the
necessary support
from
the coastal
authorities,
also
in
relation
to
municipalities, for
the
remaining permits for
our
installation
and
maintenance
activities.
Next
step
We
like
to
present
our
USP, give an elucidation
about
our approach and answer
your
questions. After
mutual understanding
we
have
the
intention to
start
up
the
process to
transfer
this
USP to
a
contract.
We
look forward
with
interest
to
receive
your
response and
we
are available for
a
presentation.
Yours
