Problems to be solved
Near coastal morphodynamic, being of high natural variability, is supervised
by the coastal management to preserve the environment. In this the authority
has to manage permanent human intervention as dredging, beach nourishment,
jetty construction or other coastal protection measures. To optimise these
actions it does not need data, it needs most actual thematic information to
assess the status and possible risks within the environment of the coastal
zone. This is also necessary for the security in shipping, to minimise the
risk of accidents, and for the detection of oil pollution that affects the
natural and recreational value in a negative way and endangers the use of
coastal waters as food supply area Therefore OROMA has the objective to present
the necessary information on the most actual status of the coastal bathymetry
and related processes as erosion, sediment transport and deposition. For this
OROMA will continue to develop innovative tools for mapping and presenting
morphodynamics and related processes on large areas in nearly real time. The
OROMA team consisting of 6 developers and 4 end users (coastal management)
will follow the issue to convert scientific based knowledge into the most
actual thematic information to be distributed via electronic network.
Scientific
objectives and approach
OROMA will conduct experimental monitoring to increase the effectiveness of
monitoring technologies by increasing the basic knowledge on the physics involved.
During the experimental monitoring phase of two years observation, data from
radar-, optical- and in-situ instruments will be acquired and validated. Data
will be acquired from board satellites and airplanes as well as from mobile
ground based instruments. Raw data from the different sources will be combined
and mapped into one common grid. Radar deduced information on the bathymetry
will be mapped in parallel to the optical acquisition of concentration of
suspended matter. Algorithms for data fusion, assimilation and inverse modelling
will be adapted for the assessment of the overall coastal status. Results
will be verified by ground truth observations. An operational technique to
detect trends and possible risks within the monitored processes will be developed.
Thematic information on the status and the interacting processes will be exchanged
among the experts. Extracted information, which is of value for the management,
will be comprised to thematic maps.
Expected
impacts
OROMA will develop operational mapping tools by scientific progress. It will
integrate cost effective radar and optical mapping techniques for the bathymetric
assessment. High resolution hydrodynamic surface features will be observed
by ground based radar and integrated in the mapping. OROMA will achieve a
near real time presentation of all monitored parameter. The results will be
presented as thematic information into a geo- coded grid and distributed by
electronic network to ensure actual update and to make it quick accessible
for the management. OROMA integrates end users, representing the coastal management,
by providing them the flow of information on electronic networks. It will
be their qualification, which evaluates the success of the project and the
operational usability of its product.
