119 Measurement and Modeling of in Situ Soil Water Retention

Oral Session
SSSA Division: Soil Physics and Hydrology
The relationship between soil moisture content and energy status is represented by the soil water retention curve (SWRC). The SWRC is a useful tool for characterizing many soil hydrologic relationships and for modeling water flow and chemical transport in soil. Recent technological advancements permit measurement of soil water potential beyond the traditional measurement range and allow for accurate in-situ measurements of soil water retention. Coupled with measurement advances are promising new modeling developments that better describe the real-world complexity of soil water retention. This session will highlight the latest efforts in the measurement and modeling of in-situ soil water retention.
