摘要
由于受到河床地质、地形和水文条件等因素影响,一些干旱地区和半干旱地区的河道或多或少都存在着河道渗漏问题。河道渗漏对于地下水补给、洪水演进过程、农业灌溉等方面都具有重要的影响,准确地模拟计算河道渗漏量和渗漏过程具有十分重要的意义。从河道渗漏量的估算、渗漏过程的模拟以及渗漏试验方法等3个方面对国内外在河道渗漏模拟和计算方面的研究进展进行了总结和归纳,并分析了当前研究存在的不足,在此基础上对未来河道渗漏方面的研究工作进行了展望。
The rivers in some arid and semi-arid areas are faced with river seepage problems influenced by geology and topography of river bed,hydrological conditions and some other factors.River seepage has a significant influence on groundwater recharge,flood evolution and agricultural irrigation in arid area.Therefore,it is very important to simulate the calculative process of river seepage.This paper reviewed the research progress of river seepage simulation from three aspects,such as the estimation of the river seepage amount,the simulation of the river seepage process and the seepage experiments.Also,it analyzed the shortcomings of current research.Finally,some future research directions would be discussed based on the existing research of river seepage.
