The governance strategies and regulation measures for the Yellow River have always been discussed for generations. In recent years, some researchers suggested controlling the wandering reach with the counterpart spur dikes in the Lower Yellow River to increase the sediment transport capacity. To study the effects of the counterpart spur dikes, three different kinds of runoff and sediment series were selected. The erosion and deposition situation in the Lower Yellow River was simulated by a 1-D numerical model. The results indicate that the sediment transport capacity of the wandering reach can be increased under the remediation of counterpart spur dikes. More than a half of the extra sediment from the wandering reach is transported to the downstream reach of Lijin station. The rest deposits between Gaocun and Lijin station, especially in the reach from Gaocun to Aishan station. The erosion and deposition situation between Aishan and Lijin station varies little before and after the construction of counterpart spur dikes.
