Specific Conductance Hydrograph
Specific conductance is a measure of the ability of water to carry an electric current. This ability is proportional to the quantity of ions dissolved in the water. If you study this specific conductance hydrograph and compare it to the discharge hydrograph you should conclude that the concentration of dissolved ions is inversely proportional to the discharge of the stream. Precipitation and runoff entering the river on August 30th diluted the concentration of dissolved ions, resulting in a sharp decrease in specific conductance. The specific conductance slowly rose through the rest of the week as runoff and bank storage water left the drainage area and baseflow (with its high concentration of dissolved ions) began contributing a greater percentage of the stream’s discharge.
