Evaluation Of The Embedded Environmental Impacts Of The Sanitary Sewer System Using Life Cycle Assessment, Kimberly Law

UCARE Research Products

This study identifies the overall impact that the installation and construction phase of sanitary sewer systems have on the environment. Construction data on sanitary sewer systems from small Nebraska communities was collected and compared to the operating phase of the sanitary sewer. The operating phase is the energy required for the lift station. Analyzing sanitary sewers during their entire life cycle involved the raw materials, infrastructure construction, installation, operation of the system, and maintenance.

Wastewater treatment systems are meant to reduce the negative impact that humans have on the environment. The purpose of the system is to treat and disinfect …

RESEARCH MOTIVATION The bridge piers are highly vulnerable to the impact and blast loads. The position in which they are constructed makes it difficult to install protective devices around them. By the current AASHTO standard, it is possible to under-design bridge piers for commercial vehicle impacts and other events such as blast.

OBJECTIVE To improve impact and blast resilience of bridge piers using polymeric coatings.

CONCLUSION Polymer coating of Portland cement concrete can be achieved with a good bonding. ü The polymeric coating seem to improve impact resilience of Portland cement concrete by increasing absorbed impact energy (i.e., area underneath …

Measuring Landscape Performance: Case Study Investigation, Hannah Michelle Lopresto, Brandon Zambrano, Catherine De Almeida

UCARE Research Products

Participating in the Landscape Architecture Foundation’s 2018 Case Study Investigation has been an incredibly informative experience for our research team at the University of Nebraska-Lincoln. We are eager to shine a spotlight on the landscape performance of two Great Plains projects: P Street Corridor, a revitalized downtown streetscape in Lincoln, Nebraska, and Tom Hanafan River’s Edge Park, a waterfront redevelopment in Council Bluffs, Iowa. Working on the post-occupancy study of both projects has been extremely beneficial in understanding how reclaiming underutilized sites can create high-performing landscapes. Both are public projects in urban settings with primary goals of transforming formerly unpleasant, …

Structural Evaluations Of Bridges With Smartphones, Garrett P. Martindale, Dean Whitfield, Jeremiah Dixon

UCARE Research Products

According to the 2013 Report Card for America’s Infrastructure, published by the American Society of Civil Engineers (ASCE), the United States has a bridge rating of C+. The C rating is classified by ASCE as a mediocre standing. Infrastructure that is awarded the C rating shows general signs of deterioration and requires attention.

Our Hypothesis: Smartphones have become readily available to anyone and is a relatively cheap device. They have instruments within them that can capture and collect usable data. An application can be downloaded to record the smartphone’s acceleration. The acceleration data can be used to evaluate vibrations within …

Research Question – Objective - Hypothesis

How does irrigation respond to the demands of Crop Irrigation Requirements under extreme hydrometeorological events?

Implement a parameterization of irrigation into the land surface hydrology model VIC.

Changes in evapotranspiration (ET) will be more conspicuous during dry years, highlighting the limiting role of soil moisture in the model.
