How to Work with This Site

The first page of the site consists of 5 elements:

1. The colored rectangle in the upper left corner
2. The main menu
3. The login panel
4. The tree view
5. The map

The colored rectangle

This rectangle is colored according to the highest alert level of the control points (CPs). The text of the corresponding alert is written in it in Bulgarian and English.

The main menu

This menu opens pages in new windows, thus keeping the map accessible all the time.

Its items depend on the level of authorization the user has:

• For the general public it opens pages with explanations how the model works, what the hydrology of the region is, etc.
• For professional users it gives access to all the information "published for professionals"—bulletins for the CPs, or for the general bulletin for the region
• For the administrators (hydrologists on duty) it gives the possibility to change some or all alert levels, generated by the model, to edit the bulletins, adding some comments, to publish some or all the bulletins for the general public and/or for professionals.

The login panel

If you are an authorized user, use it to log in. Once logged in the pannel will change to logout.

The tree view

The tree view in the left part of the first page is automatically generated, retrieving in real time the actual set of control points and published bulletins from the database and displaying them according to the authorization the user has.
