Physical processes in your basin are modeled according to specific algorithms or methods you select, based on timestep size, data availability, desired resolution or an institutional need to use a particular method. Some examples of categories of physical processes and their methods are:

• Power Generation:
  Plant Power Method, Unit Generator Power Method, Peak Base Power Method and Empirical Power Plant Method. 
  
  
• Tailwater (TW) Calculation:
  TW Base Value Only, TW Base Value Plus Lookup Table and TW Stage Flow Lookup Table. 
  
  
• Reach Routing Methods:
  Time Lag, Impulse Response, Muskingum, MuskingumCunge, Kinematic Wave and Storage Routing.
