This study was carried out to observe effects of tidal events on the water quality parameters at Merbok estuary, Kedah, Malaysia. Twenty four hours sampling were conducted at Station 1, 2 and 3 from 12 th November (spring tide) to 3 rd December (neap tide) 2011 on weekly interval. Results showed that water quality parameters varied with the following ranges: temperature (26.10 - 30.7 ° C), pH (6.29 - 7.22), dissolved oxygen (0.65 - 5.48 mgL -1 ), salinity (0.50 – 35PSU), nitrate (0.037 - 0.647mgL -1 ), nitrite (0.09 - 0.36 mgL -1 ), ammonia – N (0.03 - 3.05 mgL -1 ), phosphate (0.03 - 0.10mgL -1 ). Kruskal Wallis H test showed that water quality parameters were significantly different among sampling stations (p<0.01). Mann-Whitney U test result showed that water quality parameters were significantly different between spring and neap tides (p<0.01) except temperature and nitrate. Parameters such as temperature, salinity, nitrate, ammonia – N and phosphate recorded higher in spring tide while, DO, pH and nitrite were higher in neap tide. J. Environ. Sci. & Natural Resources, 8(2): 15-19 2015
