Welcome to www.hydromod.de/lake-jewel
On behalf of the Hanseatic City Lübeck – Department
for Environmental Protection – HYDROMOD examined the two
lakes Krähen- and Mühlenteich located close to the city
centre. This webpage aims at
presenting the different works
of HYDROMOD carried out within
the Interreg-project "Lakes – Jewels
in the Landscape"
. It is part of the project

Each surface
water is unique, because
no river and no lake is
equal to others. This of course counts also for artificial
and man made waters
like reservoirs, communal
lakes and ponds, river
enlargements, harbour basins, channels or large public swimming
pools. The
geographical position,
the incidence of light,
the landscape and its orography cause specific, location depending
conditions.
Numerous factors (e.g.
temperature, turbidity,
sediment transport, the growth of algae, etc) continuously
are changing the interaction
between parameters and
processes.

Factors like water quality, which are depending on these parameters,
can be monitored – of course with limitations - by standardised
measuring and sampling systems.
But even the application of standard devices and systems demands
for a continuous adjustment, to avoid
misleading information which may
result in severe failures with regard to recommendations and actions.
However, to gain high quality results concerning the actual state
of the lakes and to produce
secure hydrophysical forecasts about their future developments
it is absolutely necessary to apply specifically
adapted model systems. This
especially is significant in cases when prognostic simulations
on future modifications (e.g. to improve
the environmental situation of
the lakes) are carried out.
Modern model systems like "OPMOD-Lake" are able to
reproduce nature in the computer.
That’s why models are indispensable
for the simulation of different
scenarios or the optimisation
of lake regulating measures.
Their early application helps
to save costs caused by unexpected technical amendments. Prognostic
simulation models provide the
opportunity to study modifications
and their effects virtually
without any practical
cost-effective actions.
Exactly such models and their
successful application are
belonging since decades to
the major topics of HYDROMOD.
Founded in 1987 the consulting company covers
the fields of oceanography,
hydrography, hydrology and
limnology. HYDROMOD’s models
are able to provide detailed
information and prognoses
with regard to water levels, currents, salinity
and temperature as well as
to processes like transport,
mixing, dispersion, turbulence,
sedimentation and erosion.
