Trelleborg Municipality has commissioned DHI to carry out a coastal study that included:

• a baseline coastal description,
• the establishment of littoral drift budget,
• the coastal erosion conditions,
• the influence of sea level rise on erosion and coastal flooding,
• the possibilities for establishing a beach park west of Trelleborg Port, and
• an assessment of the water quality conditions along the coast.

With respect to the water quality situation the study revealed that E.coli concentrations were too high at 5 bathing sites but relocating and modification of sewer overflows and storm water discharges could significantly improved the bathing water quality at four out of six bathing sites. The small creeks that discharge into the area primarily affect the two easternmost sites. Model calculations also resulted in much better understanding of E-coli variation in time as well as space. A remarkable finding was that the concentration may become too high only in a matter of hours, and then decrease just as quickly.

The figure shows areas which will be flooded for a storm surge event with 50 years recurrence for the present sea level conditions (red) and for the conditions in year 2100 (yellow).
