Exercise 17 Solution
Using an internet search, learn that a hydrograph is a chart of the time series of water level or flow (that is, water level in a well, streamflow, stream gage height, spring flow). A chemograph is a chart of the time series of changing water chemistry (that is, groundwater chemistry, spring or stream water chemistry). Often a time series of discharge is used in conjunction a times series of water chemistry to assess diffuse versus rapid flow of water to a spring, or to estimate the groundwater discharge component of streamflow.
