Measurement of the runoff coefficient of extensive greenroof

Abstract Describes the procedure of experimental measurement runoff coefficient C, both individual layers and entire composition extensive green roofs. Experimental measurements make it possible to determine reference behaviour characteristics, namely with emphasis on simulation real The aim is an elementary description structural physical For needs measurement, dimensional shape limits test specimens are described, conditions for conditioning specimens, boundary execution steps experiment. Then specified method evaluation subsequent verification measured data. result amount drained water from tested roof at time t, which shows a nonlinear behaviour. From set data, then predict roofs in C specimens. These data represent values design sub-elements structures buildings.
