Depth-Area Relationships for Thunderstorm Rainfall in Southeastern Arizona

derstorms on the Walnut Gulch Experimental watershed in.Southeastern Arizona have provided data for deter mining a convective storm model. Three other thunderstorm rainfall mod els are compared with that developed from the Walnut Gulch data. Depth-area curves, which should be valuable for design floods, are compared for maxi mum point rainfalls of 2.0 and 4.2 in. Results suggest that air-mass thunder storm rainfall should be analyzed separ ately from frontal and frontal-con-
