| Summary : Evaluation of Sprinkler Irrigation Uniformity and Efficiency
|
Description :
Processing and analysis of field collected or simulated sprinkler
system catch data (depths) to characterize irrigation uniformity and
efficiency using standard and other measures. Standard measures include
the Christiansen coefficient of uniformity (CU) as found in
Christiansen, J.E.(1942, ISBN:0138779295, \"Irrigation by Sprinkling\");
and distribution uniformity (DU), potential efficiency of the low
quarter (PELQ), and application efficiency of the low quarter (AELQ)
that are implementations of measures of the same notation in Keller, J.
and Merriam, J.L. (1978) \"Farm Irrigation System Evaluation: A Guide
for Management\" < https://pdf.usaid.gov/pdf_docs/PNAAG745.pdf>.
spreval::DU.lh is similar to spreval::DU but is the distribution
uniformity of the low half instead of low quarter as in DU.
spreval::PELQT is a version of spreval::PELQ adapted for traveling
systems instead of lateral move or solid-set sprinkler systems. The
function spreval::eff is analogous to the method used to compute
application efficiency for furrow irrigation presented in Walker, W.
and Skogerboe, G.V. (1987,ISBN:0138779295, \"Surface Irrigation: Theory
and Practice\"),that uses piecewise integration of infiltrated depth
compared against soil-moisture deficit (SMD), when the argument
\"target\" is set equal to SMD. The other functions contained in the
package provide graphical representation of sprinkler system
uniformity, and other standard univariate parametric and non-parametric
statistical measures as applied to sprinkler system catch depths. A
sample data set of field test data spreval::catchcan (catch depths) is
provided and is used in examples and vignettes. Agricultural systems
emphasized, but this package can be used for landscape irrigation
evaluation, and a landscape (turf) vignette is included as an example
application.
