Name of Collector/Analyst/Recorder: _______________________________________
Required Information:
Sample Set number: ________
Observation: Date ________________ Time ___________ UT
Distance to Soil Moisture study site marker _____ m
Diameter of -- Inner Ring: _______ cm Outer Ring: _______ cm
Water Level Change (Interval Thickness = Upper - Lower):
Heights above ground level: Upper : ________ mm Lower : _______ mm
Saturated Soil Water Content below rings at end of experiment: ________ gm/gm
Daily Metadata/Comments: (optional)
Directions:
Make 3 sets of infiltration rate measurements within a 5 m diameter
area on a sesonal basis or 3 times during the period you choose to monitor
soil moisture (3 sets x 3 times = 9 sets/yr).
Each set consists of multiple timings of the same water level drop or
change, until the flow rate becomes constant or 45 minutes is up.
Record your data below for each SET of Infiltration measurements you make.
The form below is setup to help you calculate the flow rate.
Data analysis: Plot the Cummulative time (E) vs. Flow Rate (G).
Observations:
| A. Start |
B. End |
C. Interval (min) (B-A) |
D. Midpoint (min) (A+C/2) |
E. Cummulative (min) (D-A1) |
F. Water Level Change (mm) |
G. Flow Rate |
