Ecological flow estimation in Latvian – Lithuanian trans-boundary river basins (ECOFLOW) LLI-249
Flow regime regulation is one of the most significant pressures in Latvian-Lithuanian (LV-LT) trans-boundary river basins, where about 100 small HPP are installed and flow regime modifications are made. Hydrological regime regulation for hydropower production dramaticaly impact the biotic composition, supports production and sustainability of ecosystems. However estimations of ecological flow (E-Flow) have been carried out neither in LV, nor in LT. The overall objective of the project is to establish cooperation among the project partners in order to encourage development of new methodology for estimation of E-Flow, in compliance with standards and goals for protected areas under the WFD, Birds and Habitats Directive in Latvia-Lithuania border region.
The main project outputs are the Methodology for E-Flow estimation and Recommendations for the amendment to national water legislations in order to ensure effective implementation of E-Flow, binding the strategic planning for water uses and the permitting process. On Guidance document Nr.31 “Ecological flows in the implementation of the Water Framework Directive” based approach is used for the identification of insufficient water flow downstream HPPs and E-Flow estimation in LV-LT trans-boundary rivers. This approach includes in-situ measurements and modelling. LV-LT new common activities are designation of habitat changes due to flow regulation and planning of ecological status improving by E-Flow control.
