A Linear Tank (LTANK) model and its application in Viet nam

Abstract

     LTANK model was developed in 1985-86 by Nguyen Van Lai (Water Resources University - WRU-Vietnam) and Berndtsson R. (Lund University, Sweden) for simulating rainfall-runoff process of catchments in humid tropical zone. Its original software written in FORTRAN-77. In 1998, the software was re-written in VISUAL BASIC by Nghiem Tien Lam (WRU) running in EXCEL. The article presented results of the application for 12catchments representative 5 geographical zones the whole territory of Vietnam. The results reconfirm the model rather suitable for humid tropical small and medium catchments. It's being connected with hydraulic river system models and other kind of model become a powerful flexible model in water resources and mitigating disaster management.
