Evaluation of the Impact of Ecological Water Supplement on Groundwater Restoration Based on Numerical Simulation: A Case Study in the Section of Yongding River, Beijing Plain

Ecological water supplement relies on river channels to introduce surface water, to make a reasonable supplement of groundwater, to repair the regional groundwater environment and urban river ecosystem. Evaluating the degree of groundwater restoration after ecological water supplement (by taking app...

In 2020, the calculated ecological water infiltration amount was 102.64 × 10<sup>6</sup> m<sup>3</sup>, the affected area was 506.88 km<sup>2</sup>, and the average groundwater level rise in the affected area was 1.25 m.
