Abstract

A recurrence analysis technique using probability and contingency relationships of snow
depth, water equivalent, and snow density is presented. Three methods of estimating snow
water parameters at site A by recurrence and the presently used regression techniques are
based on (1) the value from the previous month at site A, (2) the value from a reference
site, and (3) the month to previous month contingency parameter of the reference course. The
recurrence technique (Pearson type 3) when it was tested on three central Idaho snow courses
was most useful when method 3 was used to estimate snow depth and either method 1 or 3
was used to estimate the water equivalent. Correlation of estimated values to measured
values indicated equal reliability of recurrence and regression analysis when the three methods
were used. The recurrence technique can successfully be used in estimating snow water parameters
and their probability of occurrence. This technique like the regression technique requires
a basic data set before it can be applied.
