The aim of Colorado State University's research is to develop insight into current problems and to identify potential solution strategies for consideration by water managers and users in deciding how to best meet the needs of the Lower Arkansas River Valley.

Extensive field data and modeling tools are being developed and incorporated into a decision-making framework focused on meeting multiple criteria:

• maximize the net economic benefits to agricultural production viareduction in salinity and waterlogging.
• minimize salt and Se concentrations in the river at key locations, including the Colorado-Kansas state line.
• maximize “liberated” water via reduction in non-beneficial consumptive use from high water tables under fallow alluvial land and from invasive phreatophyte vegetation (Tamarisks) along the river corridor.
• provide tradeoff information relating expected economic net benefits and salinity/Se reduction to expected implementation costs, in consideration of budgetary constraints.
