Scope1.1 This guide describes methods used for estimating soillosses due to rill and interrill erosion. All known methods

Thisguide provides complete reference citations for the variousmethods currently used to estimate soil loss by rill and interrillerosion. The referenced methods contain the rationale anddetailed procedures for determining rill and interril

Summary of Guide4.1 This guide provides guidance in selecting methods forestimating soil loss by rill and
20、interrill erosion and in predictingthe effects of various soil management practices on soil loss.5. Significance and Use5.1 A variety of methods exist for this measurement. Eachmethod has its specific applicability, limitations, and levels ofcomplexity. The users of this guide should use the descrip
21、tionsof the various methods to choose the procedure, which mostclosely meets their needs. Most of these methods are notintended to predict sediment yield (6).5.2 These methods are used to estimate the soil loss (in massof soil/unit area/unit time) from rainfall and snow melt forsite-specific factors
22、 due to rill and interrill erosion. Thesemethods can not be used to estimate soil loss from ephemeralgully or channel erosion.5.3 The estimates resulting from the methods in this guidedo not constitute a design for control of erosion. However, theoutputs of these methods may be important input into
