The objective of this paper is to assess the Extreme Gradient Boosting (XGB) machine learning algorithm\u2019s ability to classify streamflow regimes in BC, Canada. The created model is robust, with an 88.9% accuracy, and requires only readily available climate and topographic data. However, the ability of the XGB algorithm to predict streamflow magnitude is modest, and it tends to over-estimate for locations with low flow conditions.<\/p>\n<p style=\"text-align: center;\"><em>Keywords<\/em>:\u00a0 hydrology, GIS, streamflow regime, ungauged, machine learning, GWR<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Streamflow Regime Classification and Annual Discharge Prediction for Ungauged Catchments in British Columbia, Canada Using the Extreme Gradient Boosting Algorithm by Ziqiang (Kevin) Hu Abstract The prediction of the streamflow regime at ungauged locations in a stream network is a fundamental problem in hydrology.
