And correlated in the same direction, with average monthly rainfall and the amount of water in the reservoir statistically significant (p <0.05), with a correlation coefficient of 0.577 and 0.477, respectively.
And have a relationship to the same direction, with the monthly average rainfall and water content in a significant reservoir of statistics. (P < 0.05) with correlation coefficient value equal to 0.577 and 0.477, respectively.
and there is the relationship in the same direction with an average monthly amount of rain and the quantity of water in a reservoir is statistically significant ( <0.05 P) by abrasion resistance correlation equal to 0.577 and 0.477 respectively
