<br />206~ <br /> <br />HEC-2 program. <br /> <br />d. The Corps will prepare and submit to the sponsor a draft and final report including the <br />methodologies, assumptions and results of the analyses, and a hard copy of all maps. Relevant <br />back-up data and computer files will also be provided. <br /> <br />e. The Corps will coordinate their efforts with the concurrent water management <br />alternatives study being performed by a selected groundwater specialist contractor. The contractor <br />will expand the previous investigation entitled" Evaluation of Proposed Water Management <br />Alternatives to Lower the High water Table in the Arkansas River Valley Near La Junta, <br />Colorado" . <br /> <br />f. The high groundwater table in the La Junta area is a recurring problem. The CWCB <br />will contract to evaluate the problem and prepare recommendations for improvement. <br /> <br />g. Findings of the Corps planning effort will be combined with I) the contractor's study <br />findings, and 2) CWCB field investigations to produce a single document reflecting the multi- <br />objective planning initiative. <br /> <br />3. MAPPING AND FIELD SURVEYS <br /> <br />The CWCB will solicit bids from open compellllve contractors to obtain aerial <br />photography, channel and floodplain cross-sections, and rectified photo mapping. The aerial <br />photography will be at a quality and standard suitable for I) topographic mapping, 2) vegetative <br />mapping inventories, and 3), development of digital mapping files. The mapping data is needed <br />to assist with the engineering and technical analyses task for the river study. <br /> <br />4. PRODUCTS OF THE STUDY PROJECT <br /> <br />The contracted products from the mapping, planning and engineering tasks are: <br /> <br />- Hydraulic river model for estimating channel capacities at selected locations, <br /> <br />- 1996 aerial photography of the Arkansas River corridor, <br /> <br />- Recommendations for the improvement of I) river channel conveyance, 2) sediment <br />transport, as well as workable and usable solutions to groundwater problems and riparian <br />plantings and removal, where applicable, and <br /> <br />- Recommendations for channel maintenance activities consistent with current water <br />resource management and environmental policies, and in coordination with the ongoing <br />study below John Martin Dam. <br />
