Smaller-scale channel modification techniqqes cannot be approached generically, Specific points along the river may benefit *mporarily from channel modification to avoid or reduce structural damage. Existing: erratic hydraulic and sediment transport characteristics demand site-specific design, detennination of upstream and downstream effects, and consideration of overall channel stability. Because of the widely varying hydraulic characteristics throughout the study reach, a generic channel configuration addressing conveyance, sediment transport, and vegetation encroachment on banks could not be identified. . Inundation of agricultural fields by river flows can be addressed in various ways: - Structurally, through rehabilitation of eXisting berms by local authorities; - Non-structurally, through retirement of lands from production and conversion to pasture or riparian vegetation. This may be pursued individual landowners, or facilitated by the Corps of Engineers' ecosystem restoration authority (Section 1135), . Within thefloodway, cost-effective restoratiQn of native riparian vegetation can be accomplished through the Corps' Section 1135 program. Extensive opportunities for riparian restoration (including salt cedar retrioval) exist within the study area, Because the majority of these lands are privately owned, this study has not selected &j)ecific sites suitable for restoration, Landowners will require the support of a local sponsor to take advantage of the Section 1135 program. . To preventfurther encroachment on thefloorJway, coordination and education of local stakeholders is required, The Colorado Water Conservation Board and the Arkansas River Steering Committee can playa crucial!role in coordinating these general objectives in addition to facilitating all report recommendations,
