Abstract

Physical factors, such as the slope of the land, the texture of the soil, and the precipitation regime influence erosion in an area. Parts of Puerto Rico are very steep and erosion-prone. In addition, the nature of the soil and intense rainfall events promote severe erosion in these areas. Erosion can be extreme in exposed areas (cleared for a road or residential construction, or where soil is exposed due to cropping patterns or agricultural cycle.)

Purpose:

The purpose of this dataset is to estimate the relative vulnerability to erosion in Puerto Rico based on physical factors: slope, precipitation, and soil type

Process Steps

Process Step 1

CC ID: 476752
Description:

The simple indicator of the erosivity of the land is based on physical factors of the location (slope, precipitation, and a soil characteristic called K-ffactor, which reflects the erodibility of the given soil type.) This indictor does not consider the current land cover or land use. Rather, it provides an overall indicator of erosion-prone areas, and hence, areas where development / land conversion / road construction should be avoided.Inputs: 1.Slope (percentage) - for each 30m grid cell, derived from the (raw) DEM (without hydrologic correction.) 2.Precipitation during the peak rainfall month (in millimeters) - The long-term average monthly precipitation values for climate stations across the area were downloaded from NOAA's National Climate Data Center (NCDC). The mean monthly precipitation for the peak rainfall month was selected for each point location, and a 30m resolution grid was interpolated using the inverse distance weighting interpolation method. This variable was chosen because it is more indicative of the rainy season and more extreme events during the year. 3.Soil erodibility factor (K-ffactor) - the K-ffactor was obtained from the SSURGO database of the USDA.Equation 1: Vulnerability = Slope(%) x precip (mm for peak rainfall month) x soil k-ffactor
