摘要：

Inclined rainfall leads to errors in the assessment of effective precipitation in areas with rugged relief. This affects many hydrological studies such as hydrological forecasts, water erosion, determination of conditions for flash flood formation, determination of cropping conditions, etc. In this paper a nomograph is presented for the rain-gauge correction factor (Cgau), by which rainfall measured in a standard horizontal rain-gauge (Pgau) may be corrected to obtain the rainfall flux actually received on the inclined surface under study (Pact = Cgau × Pgau). The correction factor is assumed to be a function of wind (with constant wind velocity), type of rainfall, and inclination and orientation of the sloping surface with respect to the oblique rain. © 1990.
