Abstraction quantities Provide details of the abstraction quantities proposed, including any deregulated abstractions (< 20 cubic meters per day) you currently have. Number Maximum annual Maximum daily Maximum hourly Abstraction of days abstraction abstraction abstraction Peak abstraction rate location name / abstraction volume volume volume (litres per second) reference per year (cubic metres) (cubic metres) (cubic metres) Total Please show us how you have calculated these quantities or reference any supporting information submitted. If necessary, continue on a separate sheet and tick here to show that you have done this. Flow data Please send us a copy of the full flow duration Provide the flow data (in cubic metres per second) & curve for the site and confirm the method used ratios specified below: to derive this. Q95 If you have used modelling software such as Q10 LowFlows, please provide us with a copy of the Qmean output (graph, data and catchment map) What is the ratio of Q95:Qmean? including the Long Term Average rainfall. What is the ratio of Q10:Qmean? What low flow protection* do you propose to maintain in the depleted reach when the hydropower scheme is operating (in m3/s)? * Low flow protection is the flow rate above which abstraction can begin and is separate to the abstraction % take, see HGN2 for details.
