A Hydrologic Study of the Middle Spring Creek near Shippensburg, Pennsylvania

摘要: This study was conducted at two different locations along Middle Spring Creek to determine if the stream segment between measurement points a losing or gaining segment. At time of study, generally system. Measurements were taken using Pygmy Meter and state-of-the-art Acoustic Doppler FlowTracker. The used only one site compare its results those FlowTracker measurements appeared be more accurate than Meter. provides quality check information assure accuracy readings. Given that conducted, it can said baseflow contributing flow stream. geology Cumberland Valley allows for vast underground network channels.
