碩士 === 國立成功大學 === 水利及海洋工程學系 === 89 === ABSTRACT The general study of groundwater is based on Darcy’s law，it is usually valid in low velocity．However，the range of Darcy’s law is only between Reynold number 1~10 The movement of groundwater in some special geologic structure，such as in the media passing through gravel undermine eroded cavity fracture and pebble，it is similar to the flow in the channel in the pipe，and its velocity is usually high． The behavior of fluid flow in fracture is very complex，the important things that we want to know are hydraulic gradient，flow velocity，and discharge. The behavior of fluid flowing below ground is concern with both of them，so combined both of Non-Darcy flow and fracture rock is the main purpose of this study ,the first approximation is achieved under many ideal condition.
