Duration: Development October 2016 to September 2019, opertaion of plattform from 2020 ongoing
Funded by the German Federal Environment Agency

For the implementation of the Water Framework Directive lakes and streams are assessed eco-logically on the basis of so-called "biological quality components" (BQE). For the BQE a number of assessment methods have been developed in the past and operationalized with the help of var-ious software products. These products were first programmed fifteen years ago and have been updated regularly. The updates were largely limited to content-related aspects and the usability of the programs, whereas the basic architectures were not touched.

Against this background the project aims to reprogram the software products PhytoFluss, Phylib, Perlodes, and fiBs. In all cases the previously desktop-based versions are abandoned in favor of a client-server solution. The user no longer has to install the programs on a local computer, but they run centrally on a server. For this purpose files are uploaded in a defined format. The calcu-lation results are then made available to the user and all user-related data is deleted from the server. The implementation is realized in a way that any current web browser can act as a client, so that no special programs need to be installed locally. Nevertheless, all necessary functionali-ties are provided.

For the user changes in the application can be minimized. All programs use a surface that is not significantly different from a locally installed program. Opening or saving data and displaying the results is done in the well-known way. Only the data bases and the calculations will no longer be executed locally, but server-based. By focusing on a modular architecture, the user interface, data management, calculation of the individual biological components and visualization of the results are separated from each other. Future updates can be made to each of the components without affecting the other modules. The concept of online implementation also eliminates the need to reinstall a software after an update on each individual user PC.

The use of all services of gewaesser-bewertung-berechnung.de is free of charge.

At the moment the platform is only avalibale in German, but other languages are possible and might come in the near future.
