ABSTRACT. Monthly Trend Investıgatıon of the Dıscharge of a Stream in Cache County. Utah. Discharge values of streams are critical for planning the water resources of basins. Discharge values of streams may change due to many reasons such as climatological effects or human-related issues. It is essential to make estimations about the discharge values’ trends for more feasible constructions on streams. In this study, discharge monitoring station records of USGS were used to determine the trends over 50 years. The data set is belonging to the Logan River Above State Dam, Near Logan. UT station and it starts in 1971 and ends in 2020. Traditional Mann Kendall Spearman’s Rho and Sen’s slope statistical tests were used to determine the monthly trends. Additionally, a yearly investigation was performed by using the same statistical approaches. According to the obtained results, any significant trends were not detected in the yearly evaluation. However, in the monthly evaluation trends were detected for August and September.
