Once we know how our river works, we can assess what is wrong. This regards both [[HYMOQE|hydromorphological quality]] and [[BQE|biological quality]]. Based on the outcomes of the REFORM project, we recommend using the hydromorphological assessment method for ecological class assessment directly, circumventing the use of biological indicators. Degradation of quality can be due to hydromorphological pressures <hyperlink>, although it is often difficult to single out the effects of these pressures compared to other pressures in a multi-stressor environment.
In REFORM we focused on linking hydromorphology to biology, notably water plants, macro-invertebrats (aquatic insects) and fish. To do this we:
+
* developed hydromorphological assessment methods;
+
* identified potential links from hydromorphology to biology (waterplants, macroinvertebrats and fish);
+
* were able to link several biological states to hydromorphological states;
+
* developed and tested useful indicators;
+
* and produced recommendations for hydromorphological and biological indicators to show what is wrong with your river.

What's wrong?

What's in this wiki? Click image to return to the overview of river basin management plan.


The second stage of river basin planning is to assess what is wrong. In case you jumped here without scanning the How does my river work? section, be advised to check that section first.

REFORM researched methods for assessing the hydromorphology (HYMO) and biological elements. We follow the selection of elements used in the Water Framework Directive for river quality assessment. Once we know how our river works, we can assess what is wrong. This regards both hydromorphological quality and biological quality. Based on the outcomes of the REFORM project, we recommend using the hydromorphological assessment method for ecological class assessment directly, circumventing the use of biological indicators. Degradation of quality can be due to hydromorphological pressures <hyperlink>, although it is often difficult to single out the effects of these pressures compared to other pressures in a multi-stressor environment.

REFORM reviewed existing tools and developed new tools for hydromorphological assessment.
