Evaluation Of The Equations Used To Calculate Hydraulic Conductivity Values From Two-Stage Borehole Tests, Johnathon Dale Blanchard
Evaluation Of The Equations Used To Calculate Hydraulic Conductivity Values From Two-Stage Borehole Tests, Johnathon Dale Blanchard
Civil Engineering Undergraduate Honors Theses
A compacted clay liner (CCL) test pad was constructed for the purpose of evaluating the testing procedures utilized for determining hydraulic conductivity of a CCL. These procedures include ASTM D6391 (2014) Method C and ASTM D6391 Method A. Method C was recently added to ASTM D6391(2014) and was evaluated based upon comparison of results obtained from previous research with results from the data presented herein. The test pad was instrumented with volumetric water content probes and water matric potential sensors to monitor the wetting front in the soil. The data obtained from this instrumentation should be used to develop a …
Examination Of Nitrogen To Phosphorus Ratio In Nutrient Removal From Wastewater Through Chlorella Vulgaris, Courtney L. Hill
Examination Of Nitrogen To Phosphorus Ratio In Nutrient Removal From Wastewater Through Chlorella Vulgaris, Courtney L. Hill
Civil Engineering Undergraduate Honors Theses
A need for phosphorus removal is becoming increasingly evident as some wastewater treatment plants struggle to meet wastewater effluent nutrient requirements. High nutrient levels in wastewater effluents have also caused ongoing tension between the state of Oklahoma and Arkansas regarding the pollution of the Illinois River. This research seeks to establish the relationship between nitrogen to phosphorus ratio in wastewater and the level of nutrient reduction using Chlorella vulgaris. Seed cultures of Chlorella vulgaris were added into solutions with various ratios of nitrate to phosphate representative of treated domestic wastewater and the removal of nitrogen and phosphorus were measured in …

Hydraulic Conductivity Of Environmentally Controlled Landfill Liner Test Pad, Camila Maldonado Soria Galvarro
Civil Engineering Undergraduate Honors Theses
Laboratory and field hydraulic conductivity tests have been conducted on soil samples to develop and verify the zone of acceptance for liner placement. Compaction testing and flexible wall hydraulic conductivity tests were performed on fifteen (15) samples to determine the dry unit weight, molding water content, and laboratory permeability. Five of the fifteen samples were compacted at Standard proctor energy, five were compacted at 75 percent of Standard proctor energy, and five were compacted at 50 percent of Standard proctor energy. The results obtained from the laboratory portion of the testing program (the zone of acceptance) are presented. A ten …
Effects Of Piston Uplift, Piston Friction, And Machine Deflection In Reduced Triaxial Extension Testing, Morgan Race
Effects Of Piston Uplift, Piston Friction, And Machine Deflection In Reduced Triaxial Extension Testing, Morgan Race
Civil Engineering Undergraduate Honors Theses
A series of Reduced Triaxial Extension (RTE) tests were conducted on dummy (brass) and null (water) samples to determine the effects of (corrections required for) piston uplift, piston friction and system compliance associated with RTE tests. During the consolidation stage of RTE tests, the sample may be consolidated in isotropic or anisotropic stress conditions. During the shearing stage of an RTE test, the sample is unloaded in the axial direction by decreasing the deviator stress while the radial stress remains constant. Ten (10) tests were conducted on a brass "dummy" sample. The device was assembled in the same manner as …
