SITE SELECTION, DESIGN, CONSTRUCTION AND MONITORING OF A PROTOTYPE SWMIS. FINAL REPORT

Current stormwater management (SWM) policies concentrate on controlling the negative effects of increased runoff rates, volumes, and channel erosion through the use of detention basins. The stormwater management infiltration structure (SWMIS) has been examined as an alternative SWM technique to maintain the quality of runoff, as well as to augment the groundwater reserves by means of artificial recharge. Recent studies on the SWMIS have focused on the development of methods of analysis and experimental research. While these studies have been beneficial in the advancement of research of the SWMIS, they were primarily based on laboratory test and lack verification under actual field conditions. The purpose of this study was to verify the results of previous studies using actual field data. Several potential sites for a prototype SWMIS were located based on a standardized site selection method. The infiltration characteristics of the subsoil media was evaluated based on a modified analysis of the falling head test. Additionally, the optimum filter was designed based on the maximum expected infiltration rate of the subsoil. The prototype SWMIS was designed based on currently accepted design guidelines. A site plan was developed and accepted by SHA for both potential sites. It was hoped that the prototype SWMIS would be constructed on one of these two sites and monitored during storm events for a period of two years. However, the physical limitations of the potential sites made this goal infeasible. Thus, the validity of the proposed guidelines for the design and construction of a SWMIS and the viability of the SWMIS as an alternative SWM technique cannot be evaluated.
