| Title: | Minidisc Infiltrometer Data Management |
| Version: | 0.0.5 |
| Description: | A set of functions for the modeling of data derived from the Minidisc Infiltrometer device. It calculates cumulative infiltration and square root of time. Also, it calculates the A parameter based on soil physical properties. |

Cumulative infiltration and sqrt of time Using time and volume from field spreadsheets, the Cumulative infiltration and sqrt of time are calculated
Description
Cumulative infiltration and sqrt of time Using time and volume from field spreadsheets, the Cumulative infiltration and sqrt of time are calculated
Usage
infiltration(dataset, col_name)
Arguments
dataset |
A tibble or data.frame including time and volume |
col_name |
vars including time and volume |
Value
A tibble giving three new columns: sqrt_time, volume_infiltrated and infiltration
Examples
infiltration(data.frame(time = c(0, 30, 60, 90, 120, 150, 180, 210, 240, 270, 300,
0, 35, 65, 95, 125, 155, 185, 215, 245, 275, 305),
volume = c(95, 89, 86, 83, 80, 77, 74, 73, 71, 69, 67,
83, 77, 64, 61, 58, 45, 42, 35, 29, 17, 15)))
Calculates parameter A from (Philip, 1957)
Description
Calculates parameter A from (Philip, 1957)
Usage
parameter_A(dataset, col_name)
Arguments
dataset |
A tibble or data.frame including n_ho, alpha and suction |
col_name |
vars including n_ho, alpha and suction |
Value
A tibble giving two new columns: suction_num, and parameter_A
Examples
parameter_A(data.frame(alpha = c(0.145, 0.008), n_ho = c(2.68, 1.09),suction = c("2cm","3cm")))
Tabulated VG parameters Van Genuchten parameters and values of A, n and alpha for the Minidisk Infiltrometer (Decagon Devices, Inc., 2005). 12 soil texture classes and suction from 0.5 to 7 cm are tabulated
