Abstract:
The Propose of this research is to predict drought hazards occurring within the
vicinity of Lam Takhong Dam, Khun Dan Prakarnchon Dam, Thub Sa-Loa Dam, by
utilizing water volume data from the Lam Takhong Dam, Khun Dan Prakarnchon Dam, Thub Sa-Loa Dam to forecast the reservoir's water volume in the year 2022.
Additionally, the study establishes drought severity criteria based on the reservoir's
water volume. This is achieved through analyzing the forecasted water volume using
Grey Model (GM (1,1)) and Grey Verhulst Model (GVM). Furthermore, drought severity criteria are determined using clustering analysis methods, including K-Mean Clustering and Fuzzy-C Mean Clustering. The research findings indicate that the Grey Model (GIM (1,1)) provides the most accurate prediction of the reservoir's water volume and effectively categorizes drought severity into five groups. It was found that in 2022 there are different drought conditions in each dam.
