a National contingency plan dedicated to oil-spills. More precisely, the numerical
solution can be obtained in a relative short delay so that a high reactivity is possible
between numerical computation and response planning. A weakness can be under-
lined concerning the computational time necessary to quantity the sea current map
for a valuable boom geometry forecasting. To that end, pre-defined coastal current
map can be measured experimentally or numerically to dispose of the necessary
environmental hindcast for boom computation. Forecast coastal hydrodynamics can
equally be proposed to faster operational action concerning boom relevance during
a shortcoming time [

].
Such tensile membrane structure is constitutive of a complex and interdisciplinary
problem. From the fluid and solid mechanics points of view, the present study is a
structure-fluid interaction problem involving principally two liquids the seawater and
the oil. For coastal engineering and civil engineering, the boom behaviour depends
on sea current hydrodynamics and mooring or towing floating structure. Several oth-
ers approaches can be cited such as the atmospheric and oceanic interaction on wind
waves and current forcing, decision support systems using software and geographic
information system. The overall approach is dedicated to emergency situation and
disaster risk reduction of an oil-spill. The accessibility for wide and diversified audi-
ence of research results is a main issue to handle more complex situations and provide
local stakeholders participation.
The future of the scientific and operational works can be the generalization of
boom usages. In term of oil response protocol we can cite the static or dynamic oil
recovery and the mostly probable new risks [
4
]. The environmental conditions can
be more complex: current in tidal inlet [
14
], river or estuarine terminal and artificial
lakes. From a numerical analysis point of view, progress can be made to be more sure
that there is convergence of the non-linear membrane equation solution. Concerning a
view in an operational mode of coastal hydrodynamics with boom structural analysis,
the development of oil-spill model [
5
] can be made so that realistic boom boundary
condition is integrated to the oil slick moving.
