A classical approach to the assessment of the available water resources for different users, including environmental, in Europe is the Catchment Abstraction Management Strategy (CAMS). An assessment has to be made of the extent, to which natural runoff regime could be changed without affecting the sustainable functioning of the environment. The aim of the Restoring Sustainable Abstraction (RSA) is to identify over-abstraction in rivers and wetland sites and make the abstraction sustainable again. In this regard, the report presents an innovative approach for the integrated assessment and management of the water and natural resources (water ecosystems, wetlands, forest, etc.) in cases of Natura 2000 areas (on the example of Vitosha Nature Park, Sanitary Protection Zones of the Struma River Basin, etc.). In the methodology, the ecosystems are also part of the measures. Some measures (such as to restore water regime of the peatlands) are non-traditional measures for RSA and supply-side drought measure. This is a step towards improving the CAMS approach. The main stages of the improved methodology are: Modeling and assessment of climate factors and trends; Water balance modeling; Assessment of water consumption and the environmental needs; Ecological flow assessment and RSA; Simulation modeling and CAMS; Monitoring and adaptive management. A methodology and a mathematical model for determination the ecological flow in Bulgaria which is a necessary condition for achieving a good ecological status are proposed. As an object of research macrozoobentos ecosystem are considered. Emphasis is given to the places of water abstraction, water transfer, rivers at risk of not achieving good ecological potential (hot spots). Measures with synergistic effects are recommended – to protect ecosystems, for flood risk prevention, etc. The results and applications in practice are related to the Vitosha Nature Park Management Plan, Program of Measures, for the goals of WFD and Natura 2000 and supports the MoEW and Basin Directorates in determining the ecological flow and implementation the Eflow concept in Bulgaria
