| 摘要： | The present practice to discharge water from drainage pipe is to place a 4 inch PVC outlet pipe approximately every 250 feet. This 4 inch PVC discharge pipe is capped with a headwall splash block, which often becomes blocked with debris to the point where it hinders the drainage system. The objective of this experimental feature is to determine if constructing vegetation barriers around the headwalls of edge drain systems will help solve the problem of vegetation and debris from blocking the drain. |
