Disposal of saline drainage water is a significant problem for irrigated agriculture. One proposal is to recycle drainage water to irrigate salt tolerant crops until the volume has been reduced sufficiently to enable final disposal by evaporation. Part of this concept requires in-situ crop water use from shallow groundwater; and data is needed to quantify the potential use of groundwater by alt...

Rice is an essential crop in Iran that is grown mostly in areas where depth to groundwater is low. Root growth and water uptake of rice under shallow groundwater has not been thoroughly studied. This experiment was conducted to determine the lowland rice (cv. Ghasrodashti) root distribution above shallow groundwater in relation to deficit irrigation and groundwater depth in cylindrical gre...

Much is known about deep ocean ambient noise, rather less about the more highly structured and variable noise in temperate coastal waters, and rather little about the tropical shallow waters that include coral reefs and the biological diversity these ecosystems support. Interest in shallow water acoustics has been growing over the last decade, and more recently specific interest has bloomed in ...
