The causes of the pan-evaporation decline have been debated, and few researches carried out on possible effect local land use cover change regional pan-observation data series. In this paper, urbanization estimate trends over 1961–2017 was examined for series 331 urban stations, applying a previously developed dataset reference in seven large river basins China mainland. difference (transformed...

Evaporation, as a major component of the hydrologic cycle, plays a key role in water resources development and management in arid and semi-arid climatic regions. Although there are empirical formulas available, their performances are not all satisfactory due to the complicated nature of the evaporation process and the data availability. This paper explores evaporation estimation methods based o...

Micronutriens deficiency is prevalent in case of drought stress conditions, so complementary boron and zinc nutrition are important for crops to overcome drought stress. This study evaluated the effect of zinc and boron foliar application on physiological traits of sesame under different irrigation levels. The experiment was conducted as a split plot in a randomized complete block design with t...

Abstract The possibility of estimating groundwater inflow to irrigation drains in Minia, Egypt, using stable isotopes has been explored. The evaporation pan technique described here makes use of small variations in the concentration of naturally occurring stable isotopes (oxygen-18 and deuterium) in irrigation-fed groundwater and surface water as well as agricultural drainage water. The agreeme...

Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract Using two methods of eddy correlation system and evaporation pan to measure respectively the aerodynamic resistance over bare soil surface and maize field, this paper analyses the diurnal variation of the aerodynamic resistance and its rel...
