摘要
Abstract
Small and medium-sized rivers of mountainous have the characteristics of large slope and a lot of hydraulic structures,, which leads to more difficult on the water surface calculation than the plain river,.Normal water surface calculated program is diffi-cult to adapt to supercritical flow and the calculation of hydraulic structures.General water surface calculation program under the condition of supercritical flow and the hydraulic structures is more prone to mutation,, sometimes must be segmented calculated,. The calculation accuracy is poorer,, and operation is more complicated.The comprehensive regulation and administration of tiec-hang river project is used as example, water surface elevation has been calculated and compared with other application results through the establishment of hec-ras one-dimensional model.As a result, hec-ras model has advantages in water surface calcu-lation of small and medium-sized rivers of mountainous area.关键词
