A plant root water uptake model written in Fortran 77. The program was based on A.W. Warrick's soil water infiltration and redistribution model (2003, Soil Water Dynamics, Oxford University Press), with additions in (a) dynamic root growth, (b) non-uniform root distribution and water uptake, (c) effect of water stress on plant uptake, (d) root uptake compensation, and (e) soil evaporation, etc. A full documentation of the utilities of the program is in X. Dong. 2016. How to put plant root uptake into a soil water flow model. F1000Research, 5:43 (doi: 10.12688/f1000research.7686.1) and X. Dong, B. Patton, A. Nyren, P. Nyren and L. Prunty. 2010.
