ABSTRACT:
A method for locating surface deposits of porous, permeable soils having high percolation rates at locations having both permeable and impermeable soils present. During warmer periods of the year, when ambient atmospheric temperatures and soil temperatures are higher than the annual mean temperatures for the location, earth surface temperatures are measured at a plurality of points within a location. Points having relatively higher temperatures are identified as likely to have surface soils more porous and permeable than soils at points having relatively lower temperatures. The porosity and permeability of the soils at selected points may be quantified by testing the soil's percolation rates.
