Abstract
Distributed TOP model was applied to the middle Mekong river basin divided into 5 sub-basins. The model parameters were estimated from land use data. The TOP model simulation remained regular deviation for observed data. The deviation was considered as storage effects such as reservoirs and irrigation. The regular variation was extracted as a storage model. The amplitude of the regular deviation was decided by catchment area. The storage model was substituted to TOP model and solved the regular deviation.
Water balance model with distributed T
OP model evaluated the distribution of potential water resources in the middle Mekong basin. As the results, east and west region of the middle Mekong have much water in wet season and poor water during one year, respectively. This potential water resource is used as one of indices to evaluate actual water resources.
