Exploration and Graphics for RivEr Trends
Statistics and graphics for streamflow history,
water quality trends, and the statistical modeling algorithm: Weighted
Regressions on Time, Discharge, and Season (WRTDS). The modeling
method is introduced and discussed in Hirsch et al. (2010) <doi:10.1111/j.1752-1688.2010.00482.x>,
and expanded in Hirsch and De Cicco (2015) <doi:10.3133/tm4A10>.
