LNWB Ch06 Soil Processes and Inputs - SSURGO soil spatial data

Soil data from the NRCS high resolution Soil Survey Geographic (SSURGO) Database.

The SSURGO data are generally not available in uninhabited landscapes with dense vegetation, such as National Forest lands. SSURGO data are available everywhere in the Lower Nooksack Subbasin. Where SSURGO data are not available in WRIA 1, STATSGO soils datasets were merged to parameterize Topnet-WM (see Tarboton, 2007, this same data layer will be used in this Lower Nooksack Water Budget project. The soils data generally pertains to the upper 80 inches of surficial material, with data in WRIA 1 ranging from 0.03 inches to 2 feet. Soils parameterization in the 2012 work is derived using information from the soils database using data extraction and depth averaging of publicly available soils data accessible through the USDA-NRCS Soils Data Mart1 . A search for soils data for Canada was completed during earlier work (Tarboton, 2007), but adequate data available in electronic form was not found at that time

来自自然资源保护服务局（NRCS）高分辨率土壤调查地理数据库（SSURGO）的土壤数据。SSURGO数据通常不适用于植被茂密、无人居住的景观，例如国家森林地区。在诺克斯克河下游子流域，SSURGO数据无处不在。在WRIA 1区域，当SSURGO数据不可用时，STATSGO土壤数据集被合并以参数化Topnet-WM（参见Tarboton，2007年；在本 Lower Nooksack 水预算项目中，将使用同一数据层。土壤数据通常涉及地表材料上部的80英寸，WRIA 1区域的数据范围从0.03英寸至2英尺。2012年的土壤参数化工作是通过使用来自土壤数据库的信息，采用数据提取和深度平均法对通过美国农业部自然资源保护服务局土壤数据市场（USDA-NRCS Soils Data Mart1）公开获取的土壤数据进行得出的。在早期工作中（Tarboton，2007年），已完成对加拿大土壤数据的搜索，但当时未能找到足够可供电子使用的相关数据。
