Yanwachuan basin is located in Xifeng district and Ningxian County of Qingyang City, Gansu Province. It is a tributary of Malian River on the right bank of Jinghe River Basin. It is a typical loess plateau gully region. As an observation station of soil and water conservation benefits in medium-sized watershed, the experimental observation section of runoff station is a large parabolic weir, and the observation mode is manual observation. The main observation indexes are daily average discharge, daily average sediment concentration, daily average sediment transport rate, extraction of flood hydrological elements and successive flood test results. &lt;/p&gt;\n</code></pre>",
