Simulation of storm hydrographs in the Oregon Coast Range was explored using the Soil Conservation Service (SCS) curve number methodology, and by developing and testing an antecedent precipitation index (API) method. Standard SCS procedures over-estimated peak discharge by about a factor of two (i.e., average over-prediction of percent).Cited by: 8.

Linear regression was then used to establish a relationship between calculated API values and Cited by: The SCS runoff curve number method is not recommended for estimation of peak discharge nor simulation of storm hydrographs in Oregon's Coast Range. A simple rainfall-runoff model, was developed, which requires only precipitation and watershed area as inputs.\ud An antecedent precipitation index (API) was developed by decaying the residual effects of precipitation.

Application, of the an Oregon Coast Range stream, USA. The slope of the regression line is for data collected.

Reduction in the infiltration capacity of forest roads can also occur as a result of compaction by heavy equipment ().

An approach to estimate the rate of storm runoff based on an intensity-runoff relationship; Q=CIA. C is the coefficient describing runoff potential of an area, I is the rainfall intensity during the core time of concentration, and A is the drainage or watershed area.

We test our model, in a landslide-prone study area near the Mettman Ridge in the Oregon Coast Range (CB-MR), USA, where a decade-long inventory of rainfall-triggered shallow landslides is. Clearcutting the basin by percent, concurrent with access roads covering 5 percent of the basin, increased total runoff by 8 percent and increased storm volume by 6 percent.

No additional clearcutting, concurrent with access roads covering 12 percent of the basin, increased storm-peak magnitude by 14 by: 4. in total storm flow at the outlet of the large basin would be, at most, only about 1% in any given year. For a rota- tion of 50 years, the maximum increase in total storm flow at the outlet would be about 2%.
