Some studies are currently underway, such as the MDC Mystic River Hydrologic and Hy- draulic Study. Recommended hydrological and hydraulic im- provements are as follows: 1. Increase flood storage volume through dredging of ponds and stream chan- nels. This action must be closely linked to a comprehensive strategy to elimi- nate re-sedimentation from watershed inputs to the system to ensure long- term success. Potential aquatic habitat impacts must be carefully studied and minimized. 2. Increase flood storage volume by lowering floodplain elevation, , through wetland creation and removal of fill material. Eliminate structural constrictions by widening bridge openings and FIGURE 24. This stream channel is being restored using bioengineering techniques. These techniques, originally developed in Europe, combine mainly natural materials such as native plants, coconut fiber mats, and rock. They have proven very successful in restoring natural systems. 20 FINDINGS AND RECOMMENDATIONS ALEWIFE MASTER PLAN.
