A computer program was created to conduct a comparative study of five Multi-Criteria Evaluation Methods (MCEMs), each of which is capable of evaluating alternatives in a resource management setting. The MCEMs included Weighted Average (WA), Preference Ranking Organization METHod for Enrichment Evaluations (PROMETHEE II), Compromise Programming (CP),(More)
For several years, Colorado State University has been documenting flow and water quality conditions in Colorado's Lower Arkansas River Valley with the goal of providing data and models that water users and managers can use to enhance both agriculture and the environment in the Valley. Extensive measurements are being made in the field, and some previously(More)
The objectives of this study are: to compare regression kriging and Co-kriging techniques when applied to LANDSAT images to generate accurate soil salinity maps; to compare the performance of different crop types: alfalfa, cantaloupe, corn, and wheat as indicators of soil salinity; and to evaluate the best band combinations to estimate soil salinity with(More)
The flow cytometry (FC) technique used with certain fluorescent dyes (ChemChrome V6 [CV6], DRAQ5, and PI) has proven useful to label and to detect different physiological states of yeast and malolactic bacterium starters conducting cider fermentation over time (by performing sequential inoculation of microorganisms). First, the technique was tested with(More)
Knowledge is a requirement for concurrent engineering, and therefore an approach to capture and organise the different knowledge to be taken into account in concurrent engineering is proposed. This approach, known as the "MEthodology for Knowledge Engineering for Concurrent Engineering" (MEKECE) is a dedicated application of knowledge engineering(More)
Two different techniques are evaluated in this study to estimate soil salinity in the lower Arkansas River Valley area in Colorado for both the sub-basin and field scales. Inverse Distance Weight (IDW) and Ordinary Kriging (OK) are evaluated as deterministic and geostatistical techniques respectively. Deterministic techniques depend on the assumption that(More)
A comprehensive salinity monitoring program has been conducted in a portion of the Arkansas Valley in southeastern Colorado from 1999 to the present. This area was selected for study because it provides a good illustration of a salinity-affected area. The main objective of this presentation is to utilize spatial statistical modeling using information from(More)
During the 2004 growing season (May 20-August 20), irrigation activities were monitored along the 160-mile stretch between Fowler and Holly in Colorado's Lower Arkansas Valley. Fifteen fields were monitored to evaluate ongoing water use practices with an eye toward potential improvement. Ten of the monitored fields were surface irrigated, two by center(More)
