Analysis of Water Yield Changes from 1981 to 2018 Using an Improved Mann-Kendall Test

open access: yesRemote Sensing, 2022
Water yield (WY) refers to the difference between precipitation and evapotranspiration (ET), which is vital for available terrestrial water. Climate change has led to significant changes in precipitation and evapotranspiration on a global scale, which ...

Trend analyses of regional time series of temperatures and rainfall of the Tapi basin

open access: yesJournal of Agrometeorology, 2020
Climate change information at the scale of basin is vital for planning, development and use of water. The Tapi basin is climatically responsive. Hydrological response of a basin is based mainly on rainfall and temperature.

Applicability of prewhitening to eliminate the influence of serial correlation on the Mann‐Kendall test [PDF]

open access: yesWater Resources Research, 2002
Prewhitening has been used to eliminate the influence of serial correlation on the Mann‐Kendall (MK) test in trend‐detection studies of hydrological time series. However, its ability to accomplish such a task has not been well documented. This study investigates this issue by Monte Carlo simulation. Simulated time series consist of a linear trend and a
