Abstract : The premise of time series analysis is that the instream physical habitat at a given time and place can be calculated as a function of the streamflow using the equation HA(t) = PH(Q(t)) where PH( ) is the physical habitat-versus-streamflow function for a given life stage and species of aquatic organism or river activity; Q(t) is the streamflow at time t; and HA(t) is the habitat area for time t. The physical habitat represents the space in a river that can be used as habitat by a given species and life stage of fish. The assumptions and calculation procedures used to determine the physical habitat are described in Stainaker (1979). The Time Series Library (TSLIB) of programs has been developed to analyze the pattern of time-varying events. The TSLIB system can be considered a decision support system with the decision being quantification of an instream flow need, an instream flow water right, or a minimum flow requirement for operation of a water resource project. The general concept of a decision support system using TSLIB is shown in Fig. 1.1; the objective is to choose between water resource management alternatives or to modify the operation of an existing water resource system.
