AlSin Spring spurts at the foot of coastal mountains and pours in The Mediterranean sea
near Arab-Almulk village. Presently, spring water used for drinking, irrigation and
industry, while excess water goes to sea.
Current research aims to determin
e the daily discharge response to daily rainfall, and to set
an equation for recession discharge for predicting spring discharge and volumes of flow
after definite time from the beginning of spring base flow, which allows to operate and
manipulate available water resources through an optimum design of water intake from this
spring.
Response time of AlSin Spring between (3-5) days for average discrete daily rainfall with
high intensity which caused 0.5 ~ 1.0 m3/sec increasing in spring discharge value.
Yearly discharge trends to decrease with a rate of 0.0975 m3/sec between 1974 and 2016
years. While the monthly minimum discharges increase about 0.1284 m3/sec, and monthly
maximums decrease about 0.0752 m3/sec between 1994 and 2016.
We recommend adopting recession curve analysis to predict the optimal discharge of
springs within definite periods.
