The objective of the activity A5 is to prepare a plan of measures for reduction of the impact of hydromorphological modifications, which will later be implemented within the activity C9. Activity A5 has two sub-activities: A5.1, which includes the inspection and assessment of actual status of rivers of interest and A5.2 where solutions for improvement of hydromorphological quality will be developed. In order to assess the current situation, it is planned to survey not only the largest part of riverbed of each of these rivers, but also their most important tributaries. Survey will be performed following methodology of the classical River Habitat Survey (RHS) which will be supplemented by collecting of information specific to Latvia (height of beaver dams etc.). Solutions for improving of the hydromorphological quality of each river will be based on the results of this survey.
