Basis for determining Q347 flow rate
This dataset explains the legal basis for determining the Q347 residual flow rate under the Swiss Water Protection Act, which sets rules for calculating appropriate residual flows in watercourses. It applies to new water withdrawals and to existing withdrawals whose concessions are being renewed, covering uses such as power generation and irrigation from permanent, non-seasonal watercourses. Published by the Swiss Federal Office for the Environment (BAFU) under the Swiss Confederation, it provides methodological and regulatory guidance for cantonal authorities and water users involved in granting or renewing abstraction concessions and for ensuring compliance with national water protection legislation.The Water Protection Act specifies how appropriate residual flows can be determined. This applies to new water withdrawals and also to existing withdrawals for which concessions have to be renewed. Anyone who withdraws water from a permanent (non-seasonal) watercourse - for power generation, irriga…
