Comparison Of Saturated Hydraulic Conductivity Using Geospatial Analysis Of Field And Ssurgo Data For Septic Tank Suitability Assessment, Joshua Randall Weaver
Comparison Of Saturated Hydraulic Conductivity Using Geospatial Analysis Of Field And Ssurgo Data For Septic Tank Suitability Assessment, Joshua Randall Weaver
All Theses
Saturated hydraulic conductivity (Ksat) is a soil property linked to ecosystem services and it is often used in septic tank suitability determination at various scales. Field and laboratory measurements of Ksat and septic tank suitability are time-consuming and expensive. Soil Survey Geographic Database (SSURGO) data are available for the United States, but limitations of using SSURGO data for Ksat and septic suitability determination are not fully understood. The objectives of this study were to quantify and compare depth to limiting layer, thickness of limiting layer, and Ksat values for a 147-hectare Cornell University Willsboro Research Farm, located in upstate New …
Comparing Ssurgo Data Versus Geospatial Field Measurements To Estimate Soil Texture And Infiltration Rate Classes In Glaciated Soils, Stephen Austin Cole
Comparing Ssurgo Data Versus Geospatial Field Measurements To Estimate Soil Texture And Infiltration Rate Classes In Glaciated Soils, Stephen Austin Cole
All Theses
The infiltration rate (IR) of water is a key soil property related to hydrological processes, soil health and ecosystem services. However, detailed measurements of IR in the field and/or laboratory are labor-intensive and expensive to perform. Soil judging in the field provides a rapid and inexpensive method to estimate IR classes based on soil texture, soil organic carbon/matter and soil structure. The objectives of this study were to classify and compare soil texture and IR for the A horizon across the 147-ha Cornell University Willsboro Research Farm using the Soil Survey Geographic (SSURGO) database and field-based measurements. Soil texture was …
