Navigate to the Tool Box, which is the left-side bar on the screen in the default setting, select StandHyd and drag it to the desired location (somewhere in sub-catchment 1003 in this case) on the canvas and release it. A new StandHyd will be created in the given location with all default parameters.

Navigate to the Properties menu, which is right-side bar on the screen in the default setting, change the NAME (and NHYD) of the StandHyd to 1003. Spend some time to see what parameters are available and what are the default values. Notice that the default hyetograph has been assigned to the new StandHyd.

Continue to add another StandHyd for sub-catchment 1005 and rename it as 1005. At this stage, the canvas will be like the one shown below.
