Title: Geostatistics: a new tool for describing spatially-varied surface conditions from timber harvested and burned hillslopes

Author: Robichaud, Peter R.;

Date: 1997

Source: Paper no. 97-2092. St. Joseph, MI: American Society of Agricultural Engineers. [5] p

Publication Series: Miscellaneous Publication

Description: Geostatistics provides a method to describe the spatial continuity of many natural phenomena. Spatial models are based upon the concept of scaling, kriging and conditional simulation. These techniques were used to describe the spatially-varied surface conditions on timber harvest and burned hillslopes. Geostatistical techniques provided estimates of the ground cover (organic forest floor commonly called duff), which was used to classify burned-over hillslopes into low- and high-severity burn conditions. Rainfall simulation was conducted and the results indicated variability in two important erosion process parameters: hydraulic conductivity and interrill erodibility.

Keywords: erosion modeling, hydraulic conductivity, prescribed fire, erodibility
