Changes in soil moisture affect how precipitation behaves when it reaches the ground. Generally, higher soil moisture increases the potential for water from precipitation to reach streams & rivers. Soil moisture can be measured or modeled. Knowledge of soil moisture content tends to improve river forecasts.
