Overall Design and Discussion of Flood Discharge Channel Project for Zhangjiachuan County
In recent years,due to perennial seasonal rainstorm,the waterlogging in the built cities and parks has occurred frequently in the northwest China.The solution to this problem is mainly in the early stage of the construction of cities and parks.In the construction of flood drainage system in the park,not only the flood flow,but also the debris flow should be calculated.It is not only required that the drainage channel be laid smoothly,but also should follow the overall planning of the park,taking into account the impact of the existing buildings.Not only the crossing section of the flood drainage channel is calculated,but also the non-silting of the flood drainage channel is calculated.
