Sea Bathing water monitoring program was established in 1989.

Monitoring Programme is implemented by Seven Coastal Counties (Public Health Institutes)

Bathing season: 15. May until 30 September

10 sampling during the season Program is financed by the regional and

local selfgoverment and touristic sector. Currently we have 913 sampling points Bathing water profile are completed for

all beaches

Data collection

Data are collected by eight authorised institutions from seven Croatian counties. Samples were taken every two weeks, 10 times from mid may until end of September on each location. Results are inserted into web application, and instantly presented on the Internet, on public presentation application part. Data can be inserted manually trough HTML form, or by uploading file (bulk insert). All data on the public presentation pages are organised by counties and cities. There is also available search within city or location name or description. Click on the map showing locations are another way to find desired data. Google maps are used for presentation of locations and each location is color coded depending of last measured water quality. At the end of the season, locations are color coded according of final assessment. Also is available reviewing of all past measurement results.

Bathing water profile

Bathing water profile is included into web application. Main objectives of bathing water profile is pollution risk assessment. Defining beach borders and objects on the beaches on the map, and collecting data about beaches fulfull this purpos. Thought web application users can easily define geographical borders by clicking on the map in the web browser. Also it is possible to upload pictures of beaches as the part of the beach profile.

Final assessment

Final assessment of each location is automatically calculated using statistical procedures defined in the local Croatian regulation and also according EU directive 2006/7/EZ (despite lack of minimal 3 previous seasons). The Croatian regulation have more strict rules, so final assessment in case of some locations are different, regarding used procedures (showing better state in EU directive then in Croatian regulation view).

Statistical parts of various reports about sea bathing water quality are automatically generated by web application.

Browser problems

IE6 browser does not support AJAX technologies

Automatic redirection to view without AJAX for IE6 visitors

Relatively small number of this type of access

Slow javascript execution in some browsers

New browser releases have increased speed of javascript execution

Usage of standardized technologies (HTML, CSS, javascript), we avoid nonstandard techniques (Flash, Silverlight)

Future development

Development of “light” version of public page (only basic maps and essential information)

Improve quality of beach profile data Improve search capabilities regards

beach profile data (objects) Improve info for search engines
