A program for searching optimal root parameters in plant water uptake modeling

This is a Fortran 77 program designed to search for optimal root distribution and rooting depth parameters useful for modeling plant root uptake and soil water dynamics.

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. Quantifying root water extraction by rangeland plants through soil water modeling.
