Stream Discharge Measured at the Flumes on Watershed N04D

Stream discharge is measured on a catchment (N04D), with 4-year fire return interval and grazed by bison since 1992. Measurements are taken at 5 minute intervals at a triangular throated flume. The prairie streams are 3rd-order and are intermittent. Daily and stormflow discharge records are available.本研究针对集水流域（catchment）N04D开展河道流量观测，该流域火灾重现周期为4年，且自1992年起由野牛进行放牧。观测采用三角喉道水槽（triangular throated flume），以5分钟为采样间隔获取数据。该区域的草原溪流为3级溪流，且属于间歇性溪流。现有日径流与暴雨径流的流量记录可供使用。
