Soil: the Unseen Layer of Water

Abstract

Healthy soil performs important functions in regulating water volume and controlling water quality. However, overlooking such dynamics between soil and water often leads to design misassumption and water system failure. For instance, the compacted soil and disturbed soil profile result in poor water retaining capacity and increased surface runoff. The organic matter loss decrease soil’s effectiveness at binding and breaking down nutrients and sediments, which further pollute the water system. To incorporate soil sciences in design and construction processes, implementing a soil management plan is suggested. The best soil practices for water system includes 1) Protecting soil structure to conserve hydrological performance; 2) Avoiding and amending soil compaction to increase water retaining capacity; 3) Conserving and restoring soil performance in water cleansing.
