The YES Network is an international association of early-career geoscientists who are primarily under the age of 35 years and are from universities, geoscience organizations and companies from across the world. About the YES Africa Symposium I blog this event according to my opinions of the session i had participated in it online via Go To Meeting , i used twitter update to blog about this event, i arranged it chronologically. I hope this be useful. Twitter Hashtags for the event was #YESAfrica2011 Starting the event 1st day 8:30 Am Amel Barich from YES-Morocco talking about her PhD research

Aquifers Properties: Specific Yield and Specific Retention

Image
Aquifers Properties: Specific Yield and Specific Retention In an aquifer with a water table (unconfined aquifer), the volume of water released from groundwater storage per unit surface area of aquifer per unit decline in the water table is known as the specific yield, S y . also known as the drainable porosity. Hydrologists divide water in storage in the ground into the part that will drain under the influence of gravity (called specific yield) and the part that is retained as a film on rock surfaces and in very small openings (called specific retention). The physical forces that control specific retention are the same forces involved in the thickness and moisture content of the capillary, fringe. fig.1
