Basic Calcs for Qbar

[wunderjah]

Really basic embarassing Question.
Want to do a check on some of my modelling outputs. does anyone have a tried and trusted method to calculate Qbar for a small area (less than 100 hectares) for 1/30 year, 1/50 and 1/100 year? we have rainfall for these storms.

thanks
