Evaluation Of Effectiveness Of Streambank Stabilization Practices And Flood Impact On Cedar River, Nebraska, Naisargi N. Dave
Evaluation Of Effectiveness Of Streambank Stabilization Practices And Flood Impact On Cedar River, Nebraska, Naisargi N. Dave
Department of Environmental Engineering: Theses and Student Research
Stream restoration has been a major environmental objective for preserving biodiversity, reducing loss of valuable cropland and improving water quality. The impact and efficiency of streambank stabilization practices has been simulated using erosion-prediction models; however, evaluation of the erosion-control practices to measure their efficiency is often neglected. This project monitored changes in fluvial geomorphology on the Cedar River in Nebraska and quantified the effectiveness of 18 sites with streambank stabilization practices. A flood event in 2010 due to dam failure acted as a major parameter in measuring the efficiency of the erosion control practices. The methodology included aerial imagery to …
Evaluating Opportunities And Barriers To Improving The Energy Efficiency Of Small Nebraska Wastewater Treatment Plants, Matthew J. Thompson
Evaluating Opportunities And Barriers To Improving The Energy Efficiency Of Small Nebraska Wastewater Treatment Plants, Matthew J. Thompson
Department of Environmental Engineering: Theses and Student Research
Wastewater treatment plants (WWTP)s account for about 0.8% of U.S. electricity use. Small WWTPs serving communities of populations less than 10,000 accounts for 95% of treatment plants in Nebraska. These plants are significantly less efficient compared to large systems and thus improving their energy efficiency (E2) is a growing focus in efforts to reduce greenhouse gas emissions associated with their operation. Energy use of plant unit operations was evaluated for several plants and included analysis of energy for space heating. Specific infrastructure and/or operational changes reported by operators following an E2 benchmarking project were evaluated by quantifying the change in …
