Investigating the conversion coefficients for free water surface evaporation of different evaporation pans

Hydrological Processes, 2004
AbstractThe conversion coefficients of free water surface evaporation were investigated. Comparisons were made between numerous evaporation tanks (pans) and a 20 m2 evaporation tank. Based on 6 years of evaporation data collected at Nansihu Lake Evaporation Station in Shandong Province, China, the following results have been obtained. First, conversion

Crop and pan coefficients for saffron in a semi-arid region of Iran

Journal of Arid Environments, 2008
Abstract Saffron (Crocus sativus L.) is an important prennial crop planted in Iran. The growing period of saffron is mostly winter and spring, which makes it a popular crop in areas with limited water supply. Crop coefficients, Kc (the ratio of crop potential evapotranspiration (ETcp) to reference crop evapotranspiration (ETo) of saffron are needed ...

Research on the influence of secondary mirror shadow coefficient upon Pan-Cassegrain system

SPIE Proceedings, 2006
Pan-Cassegrain (PC) system is a new structure, which originates from the classical Cassegrain system. The most important character of the PC system is that a 4th order aspherical surface, which can be manufactured by using the spherical fabrication technology, is added in front of the primary spherical mirror.

Estimating Crop Coefficients of Drip-irrigated Watermelons and Honeydew Melons from Pan Evaporation

2003, Las Vegas, NV July 27-30, 2003, 2003
Field drip irrigation experiments of watermelons and honeydew melons were conducted in Hetao region of Inner Mongolia, China with portable lysimeters. Crop water requirements of watermelons and honeydew melons, were estimated through water consumption of the crops under different water application, through field water balance theory.

Determining Crop and Pan Coefficients for Sugar Beet and Potato Crops under Cool Season Semiarid Climatic Conditions

Journal of Agronomy and Crop Science, 2006
AbstractThis study was conducted in a region with semiarid cool climatic conditions during the period from May to October in the years 2003 and 2004, respectively. Actual evapotranspiration (ETc) of sugar beet and potato crops was calculated according to the water balance approach.
