Inputs
Size linear/ACO-style channel drainage to BS EN 1433 using the Rational Method.
Project Information
Method: Q = C·i·A/3600 (L/s); channel capacity by Manning's formula flowing at 0.85×depth per BS EN 1433. EA May 2022 climate change uplift applied to rainfall intensity.
References: Design methodology per BS EN 1433 (drainage channels) with Manning's equation for channel capacity
