The smooth and irregular plains and low hills classes had a very low occurrence and, hence, were combined with the flat plains and hills, respectively.
Slope classes and relief classes were subsequently combined to produce eight land surface form classes (flat plains, smooth plains, irregular plains, escarpments, low hills, hills, breaks/foothills, and low mountains).
The High Plains, which occur throughout each county, are a semi-arid high plateau region classified as cold steppe (Köppen BSk) and characterized by shortgrass prairies (now predominately converted to croplands), coarse and sandy soils, and rolling, irregular plains.
The lowest erosion rates are associated with the low-relief area (irregular plains), where clastic laterite (mean 0.67 m/Ma) and quartzite (mean 2.6 m/Ma) crop out, whereas the highest erosion rates are associated with dissection of residual hills, dominated by metasandstone (mean 11.6 m/Ma) and phyllite (mean 27.6 m/Ma).
Significantly different slope comparisons between Central Great Plains (CGP), Central Irregular Plains (CIP), Flint Hills (FH), and Western Corn Belt Plains (WCBP) ecoregions are listed.
Eighteen watersheds were located in the Central Irregular Plains (CIP), characterized by irregular topography, loam soils, and a variety of land use types, including cropland agriculture, tallgrass prairie, and oak-hickory forests.
The very good groundwater prospect zones are mostly in the alluvial plains/valleys, with smooth and irregular plain geomorphological classes.
Side effects are the major reasons that women cite, with many complaining of mood swings, tender breasts, water retention, irregular bleeding or just plain feeling "crummy".
Lying between about 160 and 330 feet (50 and 100 metres) in elevation, the Kempenland contains pastureland and is the site of a number of industrial enterprises; it forms an irregular watershed of plateau and plain between the extensive Schelde and Meuse drainage systems.
South from there the plain is narrow and irregular, widening at the northern end of the Isthmus of Tehuantepec.
The contacts are generally plain, though also frequently irregular or undulating, and are classified as either conformable (more than 70% of the studied sites) or erosional (approximately 15% of the studied sites).
