“…The test was conducted on 95 m long furrows having a slope of 0.04%. Manning roughness coefficient (n) was calculated from field observations of the furrow cross-sectional area, flow rates, flow water depths and water surface width (Horst et al, 2005). The value of n was 0.037.…”

“…La mayoría de la investigación actual está destinada a mejorar la eficiencia del riego, mediante la utilización de modelos de simulación (Wöhling et al, 2004;Eldeiry et al, 2005;Mailhol et al, 2005;Mateos and Oyonarte, 2005;Walker, 2005) en general con base en experimentos de campo (Horst et al, 2005). Sin embargo, en la situación que nos ocupa, se imponía la necesidad de desarrollar una tecnología apropiada.…”

“…Sin embargo, la situación económico-financiera de los productores estudiados impide la inversión en métodos de aspersión o goteo, por lo que la alternativa posible es el riego por superficie. La solución necesaria debía contemplar el logro de buenos resultados productivos, utilizando riego superficial de una manera apropiada tanto desde el punto de vista del uso del agua como de la energía y la mano de obra, conjuntamente con un adecuado control del riesgo de erosión del suelo.La mayoría de la investigación actual está destinada a mejorar la eficiencia del riego, mediante la utilización de modelos de simulación (Wöhling et al, 2004;Eldeiry et al, 2005;Mailhol et al, 2005;Mateos and Oyonarte, 2005;Walker, 2005) en general con base en experimentos de campo (Horst et al, 2005).

“…This study was designed to identify improvements that growers could easily apply without large investments. Therefore, precision land leveling was not considered in this study although its importance in achieving high performances and water savings is known (Pereira et al, 2002;Horst et al, 2005). In this sense, laser technology is used to achieve a leveled field surface after chufa tuber harvesting.…”

“…This method estimates the field-averaged infiltration function from the field-measured geometry, inflow, advance times and recession times, thereby, requiring the determination of different measurements, including furrow discharges, furrow cross-sections, infiltration, advance times, recession times, hydraulic roughness, and furrow slopes (Horst et al, 2005).…”
