CJCZO -- Streamflow / Discharge -- Marshall Gulch -- (2006-2020)

30 minute streamflow data measured and computed for the irregular weir located at the Marshall Gultch catchment outlet (Santa Catalina Mountains,Arizona). Streamflow are derived using pressure measurements to infer water levels and hence discharge in the weir. Pressure is measured using Onset Hobo pressure transducers model U20.

15 minute discharge data measured and computed for the Seep located at the Marshall Gultch schist catchment (Santa Catalina Mountains,Arizona). Discharge is measured by directing the flow from a spring into a large custom made tipping bucket measuring 1 liter per tip. Data is logged using an Onset hobo pendant event datalogger.

针对位于Marshall Gultch流域出口（亚利桑那州圣卡塔利娜山脉）的不规则堰，测量并计算了30分钟的流量数据。流量通过压力测量推断水位，从而推算出堰的流量。压力的测量采用Onset Hobo压力传感器U20型号。针对位于Marshall Gultch片麻岩流域（亚利桑那州圣卡塔利娜山脉）的渗流，测量并计算了15分钟的排放数据。排放量通过将泉水流入一个特制的大容量倾倒桶（每次倾倒1升）来测量。数据记录使用Onset Hobo挂件式事件数据记录器。
