The Water Budget

Abstract

This lesson will build on the previous lesson which introduced the hydrological cycle and water movement through soil and the vadose zone. In this lecture we will introduce a water budget concept in the context of groundwater and surface water. At the end of this lesson you should be able to: • Explain precipitation, evaporation, transpiration and the compartment model. • Discuss the concept of changes in storage for surface water and groundwater basins • Explain how stream flow and groundwater levels are measured to asses change in storage over time GL6020 Hydrogeology, Contaminated Land and Assessment
