The hydrologic units are arranged or nested within each other, from the largest geographic area (regions) to the smallest geographic area (cataloging units) each hydrologic unit is identified by a unique hydrologic unit code (huc) consisting of two to eight digits based on the four levels of classification in the hydrologic unit system. The hydrologic soil group refers to the infiltration potential of the soil after prolonged wetting group a soils: high infiltration (low runoff) sand, loamy sand, or sandy loam. Soil hydrology this web map allows you to view multiple soil hydrology properties in one web map click on any soil map unit and the map will display information for hydric classification, hydrologic group, drainage class, flooding frequency, ponding and slope in a single pop-up window.
Name position/title organization email phone topic area(s) marty adkins: state resource conservationalist. Digit hydrologic units in the state of iowa the second part of the study involves two study areas, consisting of two hydrologic units (nine counties total) the eight-digit hydrologic unit encompasses o’brien, plymouth, sioux, franklin, hamilton, hancock, hardin, marshall, and wright counties the location of these counties can be seen in figure 2. A cataloging unit is a geographic area representing part of all of a surface drainage basin, a combination of drainage basins, or a distinct hydrologic feature these units subdivide the subregions and accounting units into smaller areas.

Kristie franz → surface water hydrology william simpkins → groundwater hydrology (hydrogeology) alan wanamaker → isotope geochemistry elizabeth swanner → biogeochemistry research the hydrologic sciences group focuses on improving our understanding of the processes that control the movement of water on the earth.
A hydrologic unit has a single flow outlet except in coastal or lakefront areas as stated by the federal standard for delineation of hydrologic unit boundaries , a hydrologic unit is a drainage area delineated to nest in a multi-level, hierarchical drainage system. Hydrologic unit map (based on data from usgs water-supply paper 2294) the gray lines are state lines, the blue lines are major rivers, and the white lines are water-resources region boundary lines. Soil hydrology of the united states communities / soils soil hydrology dominant, and weighted average drainage class values for the soil map unit the maximum drainage class is the value for the component with the largest value in the map unit, while the dominant drainage class is the component with the largest proportion of the map unit.
