Results & Analysis 

Results

The comparisons of different strategies for all the variables are shown in the histograms below.

 Analysis

From the results of the strategies following analysis is done:

Strategy 1 – The strategy of rainwater harvesting itself suggest that there would be decrease in   the demand of the domestic water, so there is a decrease in the domestic supply also. The agriculture water demand and supply also decreases. There is also a decrease in the ground water volume and level, which could be due to the increase in the population and less seepage of water in the ground from the rainfall (precipitation). Also the water demand and supply for the industrial sector grows as more water is available, due to the decrease in demand of the other sectors because of the distribution policy.

Strategy  2 -  Due to drip irrigation the  agriculture water demand an supply decreases and the  ground water level and volume increases. This shows that the major demand of the is water is from the agriculture sector. Due to result of this there is more supply of water to the increasing demand in the domestic and industrial sector. The population also increases and the amount of nitrate is almost the same.

Strategy  3 –  Due to the recycling of water the demand and supply for all the sectors i.e domestic, agriculture and industrial increases, as more water is available. The groundwater volume and level and the amount of nitrate increases slightly but the population increases to a greater extent.

Strategy  4 -   The results of desalination of the sea water is almost the same as the recycling of the water but the only  differences are that the amount of increase in the groundwater level and volume is to a greater extent, but the amount of pumped water also increases as more amount of ground water is available and the amount of nitrate has also increased to a greater extent.

Strategy  5 -  As the birth rate is affected the population decreases. The domestic and industrial water supply and demand also decreases due that. The agriculture water demand and supply increases, as more water is available. There is a minimal decrease in the ground water volume and level and also the concentration of nitrate.

Strategy  6 -  Changing the nitrate content per liters of water , there is a decrease in the amount of nitrate but there is not much change in all the other variables. Hence this strategy can be used to improve the quality of the groundwater as no variables are affected.

Strategy  7 -  By changing the percentage of the irrigated and eh non irrigated area, the results are almost the same as the existing situation. So probably the more experiments should be done on changing the percentage that would give s the results.

Conclusions Of Strategies

Strategy 4 of desalination of sea water for use has the best results to cope up with water demand and supply for all the sectors and it also improves the groundwater conditions i.e. volume and level, but it doesn’t cope up with the population and the amount of nitrate. The strategy 5 deals with the population and the strategy 6 deals with the nitrate problem. So one strategy in itself is not enough to cope up with the problems of Azag strip.
