The Effects Of Evapotranspiration Upon Recharge Using The Stable Isotopes Of Oxygen And Hydrogen In The Carbonate Aquifers Of The Cumberland Plateau In Southeast Kentucky, Lee J. Florea
Lee J Florea, PhD, P.G.
In this brief manuscript, we consider the variation of the stable isotopes of oxygen, δ18O, and hydrogen, δ2H, in samples collected during 2010 and 2011 from precipitation and shallow groundwater along the Cumberland Plateau of southeast Kentucky. These data from the 1,900-ha Redmond Creek karst aquifer lend insight into the source and timing of recharge to shallow groundwater in the epigenic karst of the U.S midcontinent. Specifically, we find that only 43% of precipitation remains as potential recharge after accounting for evapotranspiration, and 85% of this potential recharge occurs during only four two-week sampling periods. The isotopic composition of precipitation …

Efficient Water Conservation In Agriculture For Growing Urban Water Demands In Jordan, Raed Al-Tabini, A.R. Octavio, A,W. Frank, R. Phillips
Efficient Water Conservation In Agriculture For Growing Urban Water Demands In Jordan, Raed Al-Tabini, A.R. Octavio, A,W. Frank, R. Phillips
Raed Al-Tabini
A significant challenge worldwide is to increase food supply to accommodate a population growing to 10 billion in the face of climate change. Per capita water supply in Jordan is among the world’s lowest. Despite this scarcity, three quarters of Jordan’s water use is consumed by irrigated agriculture, while producing low economic values at the margin compared to urban uses. However, irrigated agriculture supports Jordan’s food security, so its policymakers continue to examine measures to produce more crop‐per‐drop in irrigated agriculture to permit scarce water to meet growing urban demands. This paper examines economically efficient measures to conserve water in …
