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%).
This research aims to develop a mathematical model linking the available water resources and the demand of population and agricultural and industrial on these resources, where they were to rely on time series from 2000 until 2011 and study and know t
heir direction and growth, and it was the most important results:
1- increasing the size of the demand (population, agricultural and industrial ) on water resources during the period (2000-2011), where he found a positive relationship between the size of a very strong demand on water resources and time.
2 - increasing the volume of surface water resources and groundwater available during the period (2000-2011), where he found a positive relationship and a very solid between the size of surface water and groundwater resources and time available.
3 - there is an excess of total available water resources and the total volume of demand.
4 - there is a statistically significant relationship between the total volume of available water resources, and demand (population, agricultural and industrial) on them, where we can and relying on multiple regression equation to predict the total volume of water resources through the volume of demand ( population, agricultural, industrial) on them.
The water resources and water availability is main source for understanding the
threshold of Urbanism resources limitation; and any imbalance in water resources specifications reflexes a
crises for cities expansion, population growth, and activitie
s variety, mostly the planner depends on
providing some general recommendations about water uses and suggesting simple strategies for
correcting the deficiency without considering the needed consideration.
That drew the research to study ers Damascus the water of in city water future which should be worried
about, throughout a review on the former urban studies and look at the related balance water studies and
the adopted future population increase scenarios, and its impacts on the expansion areas; in order to
propose a system for planning, evaluating, and allocating the limited water resources, between the
agricultural, urban, and environmental uses; whereas full integration between supply, demand, and water
quality will be achieved , throughout compact indicators, manage building a model (Model) which will be
a tool for integrated planning method of water resources; can be adopted to study the future needs of
water in the short, medium and long terms.
The research aims to estimate allocated to quench agricultural areas in the coastal region, the amount of water during the period 2002-2012 in case of the use of modern irrigation (drip and sprinkler irrigation) instead of the traditional surface irr
igation according to water legalized each method and the rate of efficiency, as well as to estimate the losses in irrigation networks allocated to agriculture and the development of appropriate pricing mechanisms of government. Find the historical and descriptive approaches adopted, and it was the most important results:
1- The results showed that if the use of drip irrigation surface irrigation in the quench-based surface irrigation acreage allowance contributed to supply up to 40% of the water used in surface irrigation amounts, and an average (174 973 785) cubic meters during the period 2002- 2012.
2- The results showed that if the use of sprinkler irrigation surface irrigation instead of the quench-based surface irrigation acreage for contributed to the supplied amount to 28% of the water used in surface irrigation amounts, and an average (122 481 649) cubic meters during the period studied.
3- economic pricing of agricultural water demand for current pricing varies, it was found that there is a deficit in the recovery of operating and maintenance costs of the territory of farmer beneficiaries of the water public irrigation networks and adult (21,500) per hectare, compared with what is being collected (3500) for. Q per hectare.
This paper focuses on climate change in Nineveh based on climatological data records in
this governorate. The general trend of the temperature appeared to surpass its average mean.
The severe hot days also increased in summer, the precipitation in
general deceased practically
in the last two decades, irregular and delayed distribution of the rain, as well as drought cycles
did occur.
Barada and Auvage basin, experience of limited water resources against
growing of human activities related to increasing of inhabitants, and climate
changes influence on precipitation and water balance. This research focuses on
the definition of p
resent and expected water shortage in Barada and Auvage
basin within the period between 2012-2035 year, and the abilities of its changes
regarding the increasing of the gap between supply and demand, and the role of
integrated groundwater resources management in facing water challenges, so
decreasing of water shortage, taking into account, sustainability of ecosystems,
as an important element of integrated water resources management.
