The Yom River in Thailand has seen changes in sediment and runoff over the past six decades due to human activities and climate shifts. By analyzing data from 2011 to 2013 and historical records from 1954 to 2014, researchers found that sediment is mainly carried in suspension, with different ratios in different parts of the river. Sediment load in the lower basin decreased by over 50% due to changes in river slope and irrigation projects. Climate variations like floods and droughts have a significant impact on river discharges and sediment loads. The construction of the Mae Yom Barrage and land-use changes did not greatly affect sediment transport in the Yom River.
