Tom uses scale models to show why wetlands hold water and how they have been drained for agriculture. He focuses on natural wetlands found in basins that have thick layers of compacted clay, and wetlands found in basins with permeable soil where groundwater is near the surface . Tom then demonstrates how ditches and buried drainage structures were used to dry wetlands for farming.
