Abstract: Regressional analysis of historical hydrological data including rainfall and runoff data reveal that although there has not been a significant temporal change in the amount of rainfall in Simi Valley, California, there has been a significant increase in runoff and stream flow rates since the mid 1960s. There are several urban-related activities, including land-use changes in the valley, lack of capturing and storing runoff in reservoirs and a recent dewatering system, which may have contributed to the higher stream flow rates.
