chris braun Like crops throughout large sections of the U.S. Midwest, these crops are partly fed by water from the Ogallala Aquifer, a giant layer of underground water. One of the largest underground repositories in the world, the Ogallala Aquifer lies under about 450,000 square kilometers of the Great Plains—an area that includes parts of eight U.S. states. A fundamental goal of hydrogeophysics is to quantify the in-situ hydraulic conductivity of aquifers from remotely sensed geophysical data. There are a variety of established methods for quantifying hydraulic conductivity (Butler 2005), but most are point-scale methods that provide low horizontal resolution and are generally impractical for parameterizing large-scale groundwater-flow models ... book travel through concurikea collapsible wall table Precipitation extremes in the Midwest have a major impact on the region’s resources, economic sectors, and residents.
