What is a Step?

A step includes a set of instructions to perform a specific activity. For example, instructions for getting a time series of streamflow is a step. Similarly, plotting the streamflow hydrograph in Excel is a step. Separating baseflow from the streamflow hydrograph is a step. Each step has some input and output. For example, the baseflow separation step cannot be performed without an input streamflow hydrograph to create an output including the direct runoff hydrograph and the baseflow. Similarly, the streamflow hydrograph step cannot be performed without getting the streamflow data. The input and output structure associated with each step enables their use with other steps in more than one Unit. This page contains the list of existing steps available in the system.
