Abstract (2021) Site and Regional Trend Analysis of Precipitation in Central Macedonia, Greece. The purpose of this paper is to investigate the trend of precipitation in Kilkis Computational Water, Energy, and Envi- region (Greece) at the site and regional level in various time scales. At the site ronmental Engineering, 10, 49-70. level, the precipitation trend was analyzed using three tests: 1) Mann-Kendall, https://doi.org/10.4236/cweee.2021.102004 2) Sen’s T and 3) Spearman while the trend slope was estimated using the Received: January 16, 2021 Sen’s estimator. At a regional level, nonparametric spatial tests such as Re- Accepted: April 13, 2021 gional Average Mann-Kendall (RAMK) and BECD’s (Bootstrap Empirical Published: April 16, 2021 Cumulative Distributions) were elaborated with and without the effect of Copyright © 2021 by author(s) and cross correlation.
