A significant action in mitigation of the effect of harbours,
their hydrotechnical constructions and ship route canals would be
to dump the regularly dredged sediments from harbour aquatories
and ship route canals in the shallow water belt (0-5 or 6 m depth)
and not in further and deeper (>10-15 m) locations from where
the sand material practically does not return to the shallow water
belt and the shore. The dumping of dredged sediments (if not
polluted) in shallow areas closer to the shore began in 1993. Only
a small amount was transported to land.
During the past 10 years, protection of the solid shore from
storm erosion was begun, but only in a relatively small area due
to restricted financial resources. Coastal protection against
erosion is urgently required for a longshore length of about 4,000
m. In some locations, actions for protection of threatened coastal
segments have been carried out, which have been mainly financed by
municipalities, harbours, or individual land or building owners.
That includes creation of a belt of large boulders, strengthening
of the eroded shore with concrete blocks, formation of a moraine
clay ridge, planting, renewal of foredunes.
In 1997, Integrated Coastal Administration and Management Plans
for Latvia and Lithuania were adopted.
