Paper Title
Simulation of Dissolved Oxygen in Maeklong River in 2017, Samutsongkhram, Thailand

This research collected the essential hydrological data eg. cross-sectional area of river, water level, dissolved oxygen, water level, water velocity from some locations in the water then applied the MIKE HYDRO RIVER model version 2017 in data processing to simulate the value of dissolved oxygen along the Maeklong river for a length of 20.4 km between January and June 2017. The results from the simulation are generally consistent with the field data. The lowest and the highest DO found in this study were 0.13 and 5.70 mg/L, respectively.
