Technical Abstract: In the Southern High Plains (SHP) of Texas, irrigated cotton occupies > 600,000 ha above the Ogallala Aquifer and receives > 2 billion m3 of irrigation pumped from the aquifer each growing season (TASS, 2010). The relationship between irrigation pumping and the sustainability of the aquifer has been emphasized recently by the proposal of well production limitations by the High Plains Underground Water Conservation District (HPWD, 2011). These regulatory restrictions will increase demand for tools that provide water balance information at temporal and spatial resolutions, and scales appropriate to support management decisions. The model PALMSCot, a combination of the PALMS model (Precision Agricultural-Landscape Modeling System) (Molling et al., 2005) and the Cotton2K model (Marani, 2004), is being developed as such a tool.
