Study On The Relationship Between BTOPMC Model Parameters And Physical Basin Features Of The Mekong River

Hydrological models are important tools to assist in water management and policy decisions. Accordingly, the ongoing development and improvement of hydrological models is necessary to help managers plan to avoid water shortages, mitigate floods and droughts, and implement integrated basin management.In hydrological modelling one of the most common and significant challenges faced is the reduction of uncertainty in estimation and calibration of model parameters,especially how to estimate parameter values for ungauged (or poorly gauged) basins and simulate the hydrological effects of basin development scenarios and water usage practices. In order to overcome these problems, a hydrological model is required of which parameters can be identified by physical basin features such as land-covers, soil types and topography. Furthermore, the International Association of Hydrological Sciences (IAHS) have recognized that it's very important to develop methods for predictions in ungauged basins (PUB) and adopted this issue as one of the core components for their ten-year PUB project.This paper focuses on investigating quantitative relationship between actual physical characteristics of the Mekong River and parameters of a physically based...
