In this study, hydrological indices variability due to land use change were assessed in the Marboreh watershed. In order to land use map preparing, maximum likelihood method was used in the ENVI software. We created land use scenarios based on land use maps and climate data. Then, after the SWAT calibration and validation, flow discharge data, and hydrological indices were simulated and extracted respectively for each scenario. Statistical analysis carried out using Mann-Kendall and t-test for hydrological indices. The results of Mann-Kendall test showed that in the first scenario, hydrological indices related to high flow including high flow pulse duration, high flow pulses days per normal flow days and high flow pulses duration per high flow counts decreasing trends at the 1% significance level. All indices (expect maximum September flow, low flow pulses duration per low flow counts and high flow pulse count in the second scenario, and high flow pulse count in the third scenario and also expect maximum September flow in the fourth scenario, had decreasing trends at the 1 & 5% significance levels. The results of t-test revealed that minimum April flow and maximum September flow in the first scenario altered at the 5% significance level with scenario #2 and #4 scenarios respectively. Low flow pulse count, low flow pulse duration, high flow pulse duration, low flow pulses days per normal flow days had altered between #1 and #4 scenarios, and high flow pulses days per normal flow days altered between #1 with #2 and #4 scenarios at the 1% significance level. Generally, the results of this study in the Marboreh watershed revealed that hydrological indices related to the minimum and maximum flows were decreased and increased due to land use changes respectively. Also, impacts of land use change on hydrological indices related to the minimum flows was higher than hydrological indices related to the maximum flows.
