Seasonal Slope Variation at Bangsaen Beach in 2014
Abstract
This study aims at seasonal variation of slope at Bangsaen beach in January, March, May, July, September and November 2014 respectively. Variations of depth at Bangsaen beach were determined from Bangsaen beach near Laemtan, Bangsaen beach and Vonnapa beach from 7 stations in total. The results show maximum changing of beach slope at station L1 ranges (-0.140)-(+0.105) m/m and minimum changing of slope at station L4 ranges (-0.115)-(+0.067) m/m in January. In March, maximum changing of slope appears at station L3 ranges (-0.123)-(+0.093) m/m and minimum at station L4 ranges (-0.081)-(+0.027) m/m. In May, maximum changing of slope appears at station L3 ranges (-0.130)-(+0.008) m/m and minimum at station L4 ranges (-0.034)-(+0.015) m/m. In July, maximum changing of slope appears at station L0 ranges (-0.136)-(+0.010) m/m and minimum at station L4 ranges (-0.036)-(+0.006) m/m. In September, maximum changing of slope appears at station L3 ranges (-0.211)-(+0.202) m/m and minimum at station L4 ranges (-0.066)-(+0.008) m/m. And in November, maximum changing of slope appears at station L3 ranges (-0.111)-(+0.015) m/m and minimum at station L4 ranges (-0.112)-(+0.003) m/m. The area between Laemtan and the middle part of Bangsaen beach shows a large slope variation in all seasons, almost never changes in slope at Bangsaen roundabout and changes slope at Vonnapa beach in Northeast monsoon. Moreover, slope of Bangsaen beach shows large variation of slope since 2006. Keyword : beach slope, Bangsaen beach, seasonal variationsReferences
