Project Summary:

To effectively manage any resource, the ability to quantify that resource, accurately distribute it, and evaluate impact or productivity is essential. Water resources are no different. Most irrigation companies and water users groups have the infrastructure in place to measure and report flow rates in canals and rivers (typically downstream of storage reservoirs). In some cases, however, weir calibrations can be inaccurate due to an incorrect reference datum, effective shorting of weir heights due to upstream sedimentation or other maintenance issues. Other issues may be due to that fact that those who perform periodic field calibrations do not understand operational procedures for the measurement equipment or they do not have access to or the ability to update the head-discharge relationships in the computer that logs the data. In other cases, telemetry systems may transmit inaccurate data or no data at all if the batteries providing power to the system are sufficiently depleted of charged. In short, in addition to having a data collection and transmission system in place, a minimum amount of maintenance, and education of users is required to insure the accuracy of the data.

With an accurate flow measurement/distribution system in place, additional information such as local soil-moisture content and evapo-transpiration rates can further assist in determining appropriate water application rates and frequencies. The process of correlating water demand, supply, and productivity (total crop yield, crop yield per unit of applied water, crop quality, and others) are essential for maximizing our water resource potential.
