Methods: 

Thirty six Campbell Scientific CS616 probes, or Time Domain Relectrometry (TDR) probes were installed in the Irrigation Transect study site early August of 2017 to evaluate soil moisture content across two topographic gradients with and without water limitations. Half of the sensors were positioned in an upland site (plot# 1-18) located along transects C and D, and the remaining eighteen sensors were positioned in a lowland site (plot# 37-54) along transects A and B. Probes were inserted in the ground at a depth of 15 cm next to a designated 1 m² plant species composition plot. Each topographic position is instrumented with a Campbell Scientific CR1000 Datalogger that is programed to collect volumetric water content every one half hour. Data is collected in the field and archived on the network server
