The water quality problems in coastal lagoon environment resulting from changes to water
and salinity budgets are reported. Direct linkage is determined between levels of water and
salinity and that of water quality indicators. As an example of a habitat under threat, a microtidal
lagoon in southern England, the Widewater Lagoon, is considered. Engineering
interventions for remedial measures along with their advantages and disadvantages of each
measure are highlighted. Such measures are believed to be crucial in devising rigorous
strategies for managing the environment of coastal lagoons.
Both economic and social considerations should, however, be included in deciding the
suitable solution to be implemented. Finally, scope for future studies is proposed which
emphasise the importance of developing reliable database and creating a vulnerability (risk)
map to identify locations in the lagoon exposed to considerable environmental strain.
