Advanced numerical simula on models can poten ally help improve guidelines for irriga on and salinity management. Many simula on model parameters have considerable uncertainty, and ideally that uncertainty should be refl ected in model predic ons and recommenda ons. In this work, we inves gate solute transport predica on intervals that can be generated by propaga ng model parameter uncertainty ...

Vegetative Treatment Systems have historically been a practice for the treatment and utilization of open lot livestock wastes. Use of these systems has been rejuvenated in recent years. A “sprinkler” vegetative treatment area (VTA) has been designed and developed as a proof of concept for addressing challenges experienced with small and medium Animal Feeding Operations. The focus of this paper ...

This study investigates which factors may influence producers’ use of irrigation technologies and/or water management practices (WMPs). One major finding is that Arkansas producers are more likely to rely on WMPs instead of sprinkler irrigation as a response to changes in depth to water and drought occurrences. This finding highlights the importance of expanding the existing literature that foc...

Methods of modifying the water distribution pattern of an impact-drive sprinkler are described. A method of pattern modification called intermittent diffusion is introduced. A deflector attached to the drive arm intermittently diffuses the jet of a standard circular-orifice nozzle, producing desirable pattern shapes while maintaining a large pattern radius. Uniformity of application for both wi...

Scarcity of fresh high-quality water has heightened the importance of wastewater reuse primarily in dry regions together with improving its efficient use by implementing the Subsurface Drip Irrigation (SDI) method. Sustainable effluent reuse combines soil and plant aspects, along with the maintainability of the application system. In this study, field experiments were conducted for two years on...

Dairy manure increases the yields of dry bean (Phaseolus vulgaris L.) and spring wheat (Triticum aestivum L.) from eroded, furrow-irrigated soils and may increase corn (Zea mays L.) silage yield from steeper eroded areas under sprinkler irrigation. In a 2-year field study in southern Idaho on Portneuf silt loam (coarse silty, mixed, superactive, mesic Durinodic Xeric Haplocalcid), the effects o...

Introduction In modeling real world tasks, one inevitably has to deal with uncertainty. This uncertainty is due to the fact that many facts are unknown and or simply ignored and summarized. Suppose that one morning you find out that your grass is wet. Is it due to rain, or is it due to the sprinkler? If there is no other information, you can only talk in terms of probabilities. In a probabilist...

Current regulations for fire suppression systems in underground coal mines to protect conveyor belt installations have been in place since the Coal Mine Health and Safety Act of 1969 was enacted. Over time, the coal conveyer equipment being used and ventilation conditions underground have changed significantly, particularly the width of the conveyor belts and the use of belt air at the face. Th...

for the proper use of water resources in agriculture, it is necessary to provide appropriate irrigation system to supply crop water requirement. in the present research, using a hierarchical analysis, different types of irrigation systems were evaluated and prioritized on 1150 hectares of agricultural land of etka organization ​​ located in dorud, iran. hierarchical analysis process is one of t...
