Estimation of Collection Performance of a Rainwater Harvesting Tray with Multi Ribbed Fold Using for Forest Supplementary Irrigation Based on Grasshopper-SWMM
摘要
Abstract
Afforestation is an important approach to prevent soil erosion in dry areas,reduce water and soil loss,and solve ecological and environmental problems.However,soil drought,uneven distribution of precipitation,and low rainwater utilization efficiency in dryland seriously restrict the survival rate of seedlings.To address these issues,a Rainwater Harvesting Tray(RHT)with a multi-ribbed fold design was developed.It can effectively increase the rainwater collection area.When placed under the forest canopy,it achieves in-situ rainwater collection and infiltration to replenish soil moisture.After digitizing the structure of the rainwater harvesting tray product,the collection performance of RHT was estimated using an evaluation model based on Grasshopper-SWMM.The relative error between the calculated and measured rainwater collection amount was within 2.5%.The simulation results show that when the number of ribs on the surface of the rainwater collection tray is 26,the height of the ribs is 3 cm,and the inclination angle of the collection groove is 13°,the collection performance of the rainwater collection tray is optimal.关键词
