Simulation of a collective solid-set sprinkler irrigation controller
8 The modernization of irrigation districts in Spain is based on the construction of 9 collective pressurized networks equipped with remote control systems. In this paper, a 10 simulation approach is used to explore the benefits of introducing a collective solid-set 11 irrigation control software. The controller works in combination with a district 12 management database, real time evapotranspi...
متن کاملA Rainfall Interception Model for Alfalfa Canopy under Simulated Sprinkler Irrigation
Estimating canopy interception of water by plants during rainfall or sprinkler irrigation is a critical step for evaluating water-use efficiency. Most existing experimental studies and mathematic models of canopy interception have paid little attention to the interception losses of water by herbaceous plants. To better understand the canopy interception processes of herbaceous plants and to est...
متن کاملAlfalfa Water Use and Yield under Different Sprinkler Irrigation Regimes in North Arid Regions of China
Alfalfa (Medicago sativa) is one of the major crops grown in Northern China in recent years, however, the current serious water shortage conditions present a challenge to the growth of this crop, especially if efficient use of water is considered in forage production for sustainability. This study aimed to evaluate alfalfa productivity and water use efficiency (WUE) under different sprinkler ir...
متن کاملAdvection Influences on Evapotranspiration of Alfalfa in a Semiarid Climate
Advective enhancement of crop evapotranspiration (ET) occurs when drier, hotter air is transported into the crop by wind, and can be an important factor in the water balance of irrigated crops in a semiarid climate. Thirteen days of moderate to extremely high ET rates of irrigated alfalfa (Medicago sativa L.) were evaluated using energy balance and atmospheric coupling models to examine the mag...
متن کاملNighttime Evapotranspiration from Alfalfa and Cotton in a Semiarid Climate
Nighttime evapotranspiration (ETN) has typically been neglected in estimating water loss from land surfaces. Our objective was to quantify the contribution of ETN to daily (24-h) ET (ET24) of irrigated and dryland cotton (GossypiumhirsutumL.) and irrigated alfalfa (Medicago sativa L.) grown in a semiarid climate. The results were then examined using a Penman–Monteith ETmodel which separates con...
