Development and Validation of Hydrological Circulation Model using MIKE11 in the Chao Phraya River Basin, Kingdom of Thailand

Abstract

In order to assess the effect of human activities, such as land use change and large-scale reservoir development on river flow regime, we have developed a hydrological circulation model using MIKE11 for the Chao Phraya River basin. We have tested the effectiveness of this model. River discharge and water level during 1956-1962 when large-scale development had not been carried out in the Chao Phraya River basin yet were simulated using MIKE11.This model was able to estimate the river discharge and water level with a high degree of accuracy. Comparisons with the actual measurements have proved the validity of our model.
