Abstract In order to respond corroding law from channel level and analogy among same levels , the grading method of American physiognomy geometry ration math model put forward by A. N. Strahler, which stressed that I penstock was minimum penstock of no embranchment and the new penstock joined and formed by two I penstocks intituled Ⅱ penstock , and the like , is adopted to grade on the relief map of ten thousandth. The application of dam series status quo analysis and layout in three small representative valley of loess hill gully has acquired anticipative purpose. Disposing different scale project respectively according to channel level is convenient for dam series layout tending towards scientifical-ness and standardization, at one time for physiognomy research developing quantificationally. Therefore adopting Math Model of American Physiognomy Geometry Ration to Channel Grade, water and soil lose law study, physiognomy geometry ration analysis and dam series layout takes on pervasive academic significance and practical value.
