When the team of the Ministry of Water Resources, Irrigation and Electricity and the Groundwater and Wadis Directorate arrived in my village to install a rain gauge and evaporation pan
, the community selected me to support the team since I had prior construction experience as mason.
Chen, 2012: Wind-induced splash in Class A evaporation pan
The water amount used for irrigation treatments is calculated based on evaporation measured by Class A evaporation pan
by using the formula given below.
Irrigation scheduling using small evaporation pan
and computer program for developing countries.
In this research, using 14 empirical methods of evapotranspiration estimation in monthly scale for the area concerned and eventually, comparing outputs and data from evaporation pan
, best empirical relation for each month is suggested.
It is included in this research the distiller in the form of four-sided pyramid, where the structure allows a better use of solar radiation during the day, combined with studies on the inclination of the faces and the water depth in the evaporation pan
to improve the production of distillate.
Precipitation and evaporation were measured with a standard rain gauge and a class A evaporation pan
, respectively, that were installed near the ponds.
Irrigation was performed on Class A Evaporation Pan
for each treatment.
The evaporation data worksheet, [E.sub.pan], measures the evaporation data from the evaporation pan
. In order to determine reference operation E[T.sub.o], one has to multiply the data from the evaporation pan
with pan coefficient that can be chosen from 1 to 2.1, with the interval of 0.1 .
The factors studied included irrigation according (50, 100 and 150 mm water evaporation from evaporation pan
) and planting densities (6, 9, 12 and 15 plants/[m.sup.2]).
data [E.sub.pan] can be used to calculate reference ET or crop [ET.sub.c] with the appropriate coefficient.
The evaporation pan
used to estimate the water loss is located on a bluff above the lake at Pierre, and it takes the corps' office about an hour each day to make measurements at the site.
