Summary

Multi Order Hydrologic Position (MOHP) raster datasets: Distance from Stream to Divide (DSD) and Lateral Position (LP) have been produced nationally for the 48 contiguous United States at a 30-meter resolution for stream orders 1 through 9. These data are available for testing as predictor variables for various regional and national groundwater-flow and groundwater-quality statistical models. The concept behind MOHP is that for any given point on the earth’s surface there is the potential for longer and longer groundwater flow paths as one goes deeper and deeper beneath the land surface. These increasing depths correspond to increasing stream orders. Or in other words, with increasing depth these paths of groundwater flow travel further [...]

Purpose

These data are available for testing as statistical predictors in regional and national groundwater-flow and groundwater-quality models. DSD and LP can be tested individually as predictors or in combination with one another. The reason for producing these measures is that longer groundwater flow paths provide, for example, greater opportunity for minerals to dissolve or for geochemical reactions to occur. In this manner DSD and LP, varying by location and stream order, are expected to be useful as potential predictors of groundwater quality as well as groundwater-table surfaces.
