Abstract: Abstract:The paper demonstrates the potential of a rainwater cistern design based on a probabilistic approach. Traditional cistern designs do not allow any water shortage. The tank-size design in this study permits the possibility of failure to account for the characteristics of the crop, which must sustain water shortage to a certain degree at infrequent intervals. Sequential peak analyses, combined with the failure probability concept, were adopted in the analytical procedure. A hilly area in northern Taiwan was selected as the study site, where water shortage is a severe problem for tea cultivation. Rainfall records and water-demand information were collected for analysis to determine an adequate tank size for a stable water supply. The determination of the tank size is related to the rainwater abstraction coe$cient, the ratio of the cultivated area to the rainwater collecting area and the failure probability. The results are expressed as a regression equation to provide a convenient way for farmers to set up cistern systems in this area.
