Intraspecific variation in growth of marsh macrophytes in response to salinity and soil type: Implications for wetland restoration
R.J. Howard
2010, Estuaries and Coasts (33) 127-138
Genetic diversity within plant populations can influence plant community structure along environmental gradients. In wetland habitats, salinity and soil type are factors that can vary along gradients and therefore affect plant growth. To test for intraspecific growth variation in response to these factors, a greenhouse study was conducted using common...

Y. Luo, M. Sophocleous
2010, Journal of Hydrology (389) 325-335
Groundwater evaporation can play an important role in crop-water use where the water table is shallow. Lysimeters are often used to quantify the groundwater evaporation contribution influenced by a broad range of environmental factors. However, it is difficult for such field facilities, which are operated under limited conditions within limited...
Theory for source-responsive and free-surface film modeling of unsaturated flow
J. R. Nimmo
2010, Vadose Zone Journal (9) 295-306
A new model explicitly incorporates the possibility of rapid response, across significant distance, to substantial water input. It is useful for unsaturated flow processes that are not inherently diffusive, or that do not progress through a series of equilibrium states. The term source-responsive is used to mean that flow responds...
