Instructions1. Establish the rainfall rate (R) for the area to be drained, e.g. 75mm/hr.2. Measure the width of catchment (B) towards the proposed PolyChannel run. If thePolyChannel runs down the centre of the area, then the width of catchment is the sum ofthe two dimensions either side of the channel.3. On the flowchart project a line from B until it intersects with the 75mm/hr rainfallline.4. Next project this line upwards through the base line (this point gives the quantityof flow (q) in litres/sec per metre) until it hits the curved hydraulic line and thenproject the line horizontally across the graph.Starter channels5. Where this line crosses the vertical axis this gives the last three digits of thepart no. of the minimum depth starter channel (e.g. 100SK140) necessary tocope with the volume of water being discharged from the catchment area.6. To select the ‘finishing’ channel i.e. part no. 200, 150 etc, project a linehorizontally from the vertical axis until it intersects with a ‘finishingchannel’ line. From this point project a line vertically downwards tointersect with the base line, which will give you the total possiblelength of channel run in meters (which may need to include flatchannels*) to cope with the flow from the catchment area.7. To calculate the total output of water, multiplythe flow per m (q) by the length of channel run(e.g. 1.0 l/s/m x 13m 13 l/s). A suitableoutlet, from Table 7 on page 12, cannow be selected to suit the amount ofwater being discharged.
