Majid Hassanizadeh (eds.), Proceedings of Workshop on HYDRUS Applications. October 19, 2005, ISBN 90-39341125, Department of Earth Sciences, Utrecht University, Utrecht, The Netherlands. p: 69-72.

Interpretive Summary: With its wide ranging capabilities for simulating variably saturated water flow and solute transport, the HYDRUS computer code has proven to be a valuable tool for analyzing and designing irrigated agricultural systems. We briefly review three recent projects that illustrate the versatility of the model and software. The first project demonstrates the use of HYDRUS in analyzing drip irrigation systems. The second shows the model's capabilities for simulating the effects of salinity and drought stress on root water uptake. The last illustrates an inverse modeling approach to assessing upward water flow from shallow groundwater.
