Measuring Hydraulic Conductivity Using Flexible Walled Permeameter And Astm Method D5084, Bradon Povah

Master of Science in Environmental Sciences and Management Projects

This project is a guide that details the protocol synthesized from the ASTM D5084-16a method, the Humboldt control panel manual, and the time spent learning the intricacies of the Permeability Cell instrument.


Characteristics And Management Implications Of Mollic Soils In Forest Versus Grassland Settings In Central California, Brian Charles Clark Mar 2021

Characteristics And Management Implications Of Mollic Soils In Forest Versus Grassland Settings In Central California, Brian Charles Clark

Master's Theses

Efforts to sequester soil carbon (C) should consider soils intrinsically capable at C retention. Of the mineral soil orders, Mollisols have minimum requirements for soil organic C (SOC; over 0.06 %) and basic saturation (over 50 %). In the U.S., grasslands comprise 93% of the vegetation mapped above Mollisols. Soils beneath the southern extent of Sequoia sempervirens (redwood) forests in central California are mapped as Molliols. It widely accepted that redwood forests harbor considerable biomass C, but the extent to which aboveground C is retained in the soil is not well understood. This study aimed to: (i) to gather baseline …
