Description:
Abstract:
A map of soil parameters in digital format was derived for the international watershed of Ambos Nogales generated to run in selected models. The Ambos Nogales watershed is located in southern Arizona and northern Sonora, Mexico and describes the Nogales wash, a tributary of the Upper Santa Cruz River. The Nogales Wash watershed covers 235 square kilometers, just under half of the area is in Mexico. Investigations of potential erosion revealed a discrepancy in soils data found at the international border of the watershed, in part due to low-resolution, formatting, variable nomenclature and classification systems. Historical analog soils data were automated to create a higher-resolution digital soils survey map of the Nogales, Arizona and merged with lower resolution data describing soils in Nogales, Sonora.
Purpose:
To model soil erosion and sedimentation for future planning purposes.

The most accurate soil information for the study area was in hard copy. This was available as 1:20,000 scale maps in the "Soil Survey of Santa Cruz and Parts of Cochise and Pima Counties, Arizona" (USDA, SCS & FS, 1979), a product of the U.S. Department of Agriculture's Soil Conservation Service and Forest Service in cooperation with the Arizona Agricultural Experiment Station. These maps were created according to the site conditions in 1971. Aerial photography was used to map polygonal soil types according to field test sites.

Source_Contribution:
Soils data in the Arizona portion of the watershed awere digitized and attributed according to the soil units on the map. User defined items were added to the newly digitized soil coverage feature attribute table to define the map unit descriptions: soil series. Labels were created and attribution of the new soils coverage was completed using a form-based interface provided by ESRI within ARCEDIT. The projection was defined according to the DOQQ that fostered it (UTM, Zone 12, Datum NAD83). The soil coverage is not meant to be used or displayed at any scale larger than 1:20,000 (e.g., 1:10,000).

According to a report by the City Hall in Nogales, Sonora (Plan de Desarrollo Municipal 2000-2003), the predominant soils in Nogales, Sonora are Lithosol (I) and Regosol Eutrico (Re), with a textural average of 30 cm. Lithosol is abundant in the southern region of the municipality and is characterized for the presence of abundant stony materials (lítica); its susceptibility to erosion depends on the slope of the land and vegetation developed. Regosol is located in the north and central regions of the municipality, presenting some lítica; the soil fertility and agricultural use is dependant on depth.

A digital soils map of Mexico at a scale of 1:1,000,000, derived from units of classification related to the 1970 FAO/UNESCO soil map of the world, was modified by the Directorate of the Geography of the National Territory (DDGTENAL) and digitized by the Instituto National de Estadistica Geografia e Informatica (INEGI) in 1997 and describes the Nogales area. In addition to the soil classes, the map units may be described by a chemical or physical phase..
Process_Step:
Process_Description:
The 1979 soil maps were automated for future incorporation into the hydrologic modeling within a GIS. The maps from which this dataset was made had not been rectified for distortion or registered to a coordinate system. Each map was scanned into tagged image file format (TIFF) using an 8-bit black and white drum scanner at 100 dpi. ERDAS IMAGINE was used to import the images. Automating these soils maps was done according to procedures described in Norman and others, 2002. CD-ROM's containing Digital Orthophoto Quarter Quads (DOQQ's) from the USGS were used to register and rectify the scanned soils maps. Ground Control Points (GCP's) were established by matching known locations on the soil maps to the same location identified on a DOQQ. The digital transformation was performed with the cubic convolution method of resampling to effectively associate the aerial photo with pinpoints to known coordinates and to adjust the map to accurate proportions. This method transformed scanned soils maps into registered images. Error still exists despite the high number of GCP's used to control the transformation.
