Abstract: The technology of irrigated agriculture has often been controversial. The development agencies would praise its productivity, as only 18% of the world’s cultivated land is irrigated but produces roughly 33% of the world’s ...

Abstract: This paper presents our research on the issue of water rights to return flow from irrigation of urban landscapes. Municipalities in Colorado's Front Range, with rights to transmountain water and other “use to extinction” ...

Abstract: Research was conducted to estimate grass consumptive use and return flow (deep percolation) in urban lawn water use. Two types of small lysimeters were used—a drainage-type lysimeter of 40 cm diameter and 60 cm depth and ...

Abstract: The Middle Rio Grande Conservancy District (MRGCD) was officially founded in the 1920s, but it may well be the oldest operating irrigation system in North America. Currently the MRGCD serves about 22,300 ha of irrigated ...

Abstract: Throughout the American west, irrigated agriculture has been targeted to increase water-use efficiency because of increased urban demands. Soil-moisture sensors offer a method to achieve efficiency improvements, but have ...

Abstract: Systems engineering research is conducted to analyze improvements in performance of a water‐storage and ‐distribution system in response to improved monitoring of irrigation demands. The Mahaweli system in Sri Lanka, a ...

Abstract: Results of the advance-infiltration phase from a zero-inertia model and a volume balance model in level basins are analyzed and compared. Level basin irrigation systems are traditionally more efficient than other surface ...

Abstract: Water is the lifeblood of the American West and the foundation of its economy, but it remains its scarcest resource. The explosive population growth in western United States, the emerging additional need for water for ...

Abstract: To address water shortage and improve water delivery operations, decision support systems (DSSs) have been developed and utilized throughout the United States and the world. One critical aspect that is often neglected ...
