The research aims to study the effects of the climatic elements, rain, dry heat and drought on
wheat and barley production (irrigated and rain-fed) in al-Hasakah station in the Eastern Province,
In order to achieve the objectives of the research a
series of pen'ds of time extending from 2001 to
2010, was adopted Based on the indexes, rates growth and multiple regression the most important
results were as the Following, relation:
1- There is a very strong and statistically significant between the irrigated wheat production
and rainfall, dry heat and drought index, wch was the most influential, effed followed by
precipitation drought index, and by dry heat.
2- There is no statistically significant relationship between rain-Fed wheat production and
rainfall dry heat or drought index.
3- There is a strong and statistically significant relationship between the production of
irrigated barley and rainfall, dry heat and drought index, The most influential effed was drought
index, followed by dry heat, and precipitation.
4- There is no statistically significant relationship between the production of rain-Fed barley
and rainfall and dry heat or drought index.
The research aims to study the impact of the change in rainfall on wheat Productivity
in al-Hasakah station in the Eastern Province. and to achieve the objectives of the research
were to adopt a time series first one from 1991 until 2010,was used a
nd divided by two
equal period stretching from 1991 until 2000, and the second period extends from 2001
until 2010, and so on quarterly and annual level for the amount of rain and the productivity
of wheat, and Study the effect of rainfall in both periods on wheat production.
Because rainfall in the coastal area is high and water projects are nearly missing, we think it is important to make use of available water resources. In order to predict future rainfalls and suggest proper management of resources, we created a mathe
matical model linking rainfall amounts between demand (population, agricultural and industrial) on water resources during the period (2000-2012). Results show the following:
1. Rainfalls decreased during the period ( 2002-2012) at an annual rate of (1.84%).
2. Demand on water resources increased during the period (2002-2012) at an annual rate of (3.41%) of the population demand, and (3.47 %) of the agricultural demand, and 6.25% for industrial demand.
3. There is a surplus of available water resources and the size of demand for them, with the surplus decreasing during the period (2002-2012) at an annual rate (2.97 %).
4. The estimation of the surplus between the amount of available water resources and the size of the demand for them will decrease in 2023 from what it was like in the year 2013 at an annual rate (-3.23%).
The aim of this study isto determinat the concentration of (Pb, Cu, Cd, Co, Cr , NiZn,
Fe) in storm water and their content of sediments during four seasons, the samples were
collected in four areas along Tartous beach. After make necessary treatme
nt concentrations
of elements determination by flame atomic absorption spectrometry.The results showed a
high levels of elements iron and zinc, in stormwater (138.6 μg/l - 99.7 μg/l) and sediments
(17.863 μg/l – 138.735 ppm), in all samples and there were concentrations another
elements difference between stations and rainfalls related to the human activities.
Al-Kabeer River Coastal Plain faces very important economic activities which lead to growing water demands. This research aims to define the relationship between rainfall and subterranean-water levels. In the mountainous area fissured marl and limest
one with high permeability spread. However, on the coastal plateau deposits with moderate to low permeability values spread, and water levels quickly respond to rainfall and irrigation water, which makes it get easily polluted and affected by climatic factors. Analyses and discussions of field data have led to the fact that subterranean-water levels are to do with many natural and artificial interrelated parameters. And in some cases, they can be adversely oriented, and difficult to isolate and monitor separately, and become very difficult to derive mathematical formula for describing the relationship between just two parameters (subterranean-water percentages and rainfall levels)
This study was carried out at three different forest sites in Syria in order to
determine the effect of changing rainfall, temperature and soil on kernel
productivity of stone pine (Pinus pinea L.)> these sites included: Jabal Alnabi
Mata, (Tartou
s province, L1), Dahr Alkhoser (Homs province, L2) and E′en
Jron site (Idleb province, L3). Results showed that kernel productivity of stone
pine per tree was 236.3, 252.8, 143 g per tree, and 177, 162.3, and 86.98 kg per
hectare in L1, L2, and L3, respectively. These differences were attributed due
to the variation in the composition, textured and fertility of the soil available in
the three locations studied. It was concluded that trees of stone pine grow better
and superior in Kernel productivity in humid and super-humid bioclimatic
zone.
The aim of this research is to determine the infiltration values as a basic
hydrogeological factor , which expresses the recharge of the ground water in a
group of wells in the studied area . In order to include a general introduction ,
the geolog
y and hydrogeology of the area and the explanation of the methods
have been used to calculate infiltration and evaporation values . Finally the
obtained results.
