Selected Research Projects of Dr. Ramchand Oad

The field research is sponsored by the New Mexico Interstate Stream Commission, to investigate options for the agriculture sector to be a more efficient user of water supplies from the Rio Grande. Reduced water diversions from the river, it is envisaged, will improve river ecology for fish and wildlife some of which have been listed as endangered species.

The field research is sponsored by the Agriculture Experiment Station, for the purpose of investigating the salinity problem associated with irrigated agriculture in Eastern Colorado (Lower Arkansas River). I work as a member of a team that includes two Ph.D. and one M.S. students.

Primary purpose of this field research is to evaluate the impact of cropping practices on water quality, especially the nitrate content of groundwater in irrigated fields. The research will be conducted on selected farms in Eastern Colorado.

The Colorado State Engineer's Office, the City of Colorado Springs and the Colorado Water Resources Research Institute sponsored the research. Its purpose was to evaluate the magnitude of return flows from irrigation of urban landscapes. Several cities with rapidly expanding populations (including Denver and Colorado Springs) claimed credits for the return flows. Four graduate students worked on the project as a part of their M.S degree programs.

The U.S. Bureau of Reclamation and the Environmental Protection Agency sponsored the project. Its purpose was to investigate and document the working procedures of private enterprises that deliver irrigation water to the farmers, including irrigation ditch companies and irrigation districts. The information could be used to more effectively engage these farmers' organizations in better management of water and other environmental resources.

The field research was sponsored by the Central Colorado Water Conservancy District and was conducted in the Weld County. The purpose was to monitor water use, fertilization and other cropping practices of selected farmers and access their environmental impact on water quality. One Ph.D. and one M.S. students worked on the project.

Sponsored research by the Colorado Water Resources Research Institute, 1990-91.

The purpose of the research was to develop computer aided decision support systems that can be used to make crop choices, application of inputs, and manage irrigations .
