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