Low Flow Analysis and Possible Impact of the Mekong River

摘要

In this study conducted a statistical analysis of low flow and used the following data made available of the Mekong River of Thailand from 1978-2008, time that the river has changed quite a lot and the scope of the study is using probability distribution, Weibull, Lognormal distribution and Extreme value distribution type 1(EV1) analyses low flow at various gauging stations, that found the values have very similar and chose to use the theory of General Extreme value for analyses because this way has been recognized in the analysis and study of the low flow rate better. The low flow will be lower and the low flow in the period of 1978-1991 is greater than the all of data and the data in the period of 1991-2008 and the probability form Extreme distribution , with the past record is considered a relatively small amount of normal.
