The model can be adjusted flexibly according to the demonstrated case of the actual outflow so as to meet the field requirement. The complex tank model is physically composited by three sub-models: the green-roof sub-model, the runoff sub-model and rainfall recycling system sub-model. The study uses the multi-start-Powell scheme to optimize the flow rate parameters that are used to evaluate the detention capacity of the storage facility of the water self-sustained community. The test site is located at Panchiao district, New Taipei. The study uses the complex tank model to simulate the rainfall-runoff of four rainfall events. The results show that the GM of the 2015/8/18 event is 0.181；2015/8/28 event is 0.056；2015/9/7 event is 0.219；2015/9/28 event is 0.08. The R2 (Square of Pearson Correlation Coefficient) of the calculated and observed values is 0.93 for the 2015/8/18 event； 2015/8/18 event is 0.98；2015/9/7 event is 0.93；2015/9/28 event is 0.97. which shows an acceptable correlation and that the application of the complex tank model to the water self-sustained community is adequate.
