Examining the impact of shallow groundwater on evapotranspiration from uncultivated land in Colorado's Lower Arkansas River Valley
MetadataShow full item record
The Lower Arkansas River Valley (LARV) in Southeastern Colorado is an important agricultural region of the state. However, more than a century of intensive irrigation has raised the water table under the area causing agricultural and environmental problems including water logging, soil salinization, and the leaching of salts and selenium into waterways. These issues could be mitigated by improving irrigation practices, lining irrigation canals, installing subsurface drainage systems, and implementing other strategies that lower the water table. A lower water table is expected to increase crop ...
