Construction Cost Models, Barry Dikeman

Economics and Finance

The following are a series of cost estimate models similar in format to a typical engineer’s estimate that were developed in support of our financial impact assessment report for LD 1725. The models us current material costs, labor costs, and equipment costs for the region to provide a comparative cost analysis of seven culvert replacement scenarios. The models provide information about what the cost impact of LD 1725 would be for typical culvert replacements in Maine. However, due to the inherent restrictions of the cost modeling framework we were not able to include the abundance of variables that would be …

River Sediment Sampling Methods: Causeway Building And Removal, Dillon Dittmer Jul 2010

River Sediment Sampling Methods: Causeway Building And Removal, Dillon Dittmer

Department of Environmental Studies: Undergraduate Student Theses

Abstract The Environmental Protection Agency (EPA) and U.S. Fish and Wildlife Service (USFWS) suspect that causeways have a negative impact on river ecology both when installed and when removed. The Nebraska Department of Roads routinely uses causeways as a tool in the construction and repair of bridges. Although research has not been conducted on the impact of causeway building and removal data has been collected about the impact of dams, causeways, etc. on estuaries. This data is considered subjective and authors often cite sampling methods as a source of error. Currently there are no widely used handheld sampling methods that …

Influence Of Clay Mineralogy On Soil Dispersion Behavior And Water Quality, Jessique L. Ghezzi May 2010

Influence Of Clay Mineralogy On Soil Dispersion Behavior And Water Quality, Jessique L. Ghezzi

Master's Theses

Currently, there is very little research available on nonpoint source pollution from rural watersheds. Government regulatory agencies are desperate for information regarding the causes of nonpoint source pollution, which includes the relationship between suspended soil particles and dispersion. Since soil dispersion is dependent on clay mineralogy, knowing the clay mineralogy of the soil in an area can help predict sediment loads entering the surrounding surface waters. This information is necessary to protect the resource value of our rivers, lakes, and estuaries, as well as to protect recreational activities such as fishing or hunting; but most importantly, this information is necessary …

Hanson River Watch 2009-2010

Watershed Access Lab Projects

The Indian Head River is part of the large and complex system of streams and rivers, which contribute to the South Coastal Plain Watershed. A portion of the river forms the border to the Town of Hanson from where it flows into the main stem of the North River. Further upstream, the river is called the Drinkwater which itself drains into Factory Pond directly upstream of our study site A.

Historically the Indian Head, its headwaters and tributaries provided an important fishery for alewives, shad and rainbow smelt. However, the river suffered much the same as other river systems in …


The Mashpee River: Water Quality Index & Macroinvertebrates Apr 2010

The Mashpee River: Water Quality Index & Macroinvertebrates

Watershed Access Lab Projects

The Mashpee River is a short river, flowing only 5 miles before becoming tidal and draining into Popponesset Bay. In order to determine the overall water quality of our river, we ran tests on its levels of dissolved oxygen, BOD, temperature, pH, nitrates, phosphates, turbidity, and the presence of macroinvertebrates. A low level of dissolved oxygen is a sign of pollution, but our levels were better than ideal. Healthy pH levels for most fish fall between the values 5 and 9. Our pH levels were measured at around 6, well within the healthy range. Our river also maintained stable temperatures, …

Influence Of Canopy Cover, Nutrients, And Season On Stoichiometric Variation Of Epilithon In Neotropical Streams., Tyler J. Kohler Apr 2010

Influence Of Canopy Cover, Nutrients, And Season On Stoichiometric Variation Of Epilithon In Neotropical Streams., Tyler J. Kohler

School of Natural Resources: Dissertations, Theses, and Student Research

Light and nutrient availability are strong factors determining the nutrient composition of epilithon in temperate stream ecosystems. However, little work has been performed regarding this association in tropical streams. In our study, we investigated 1) how gradients of canopy cover and nutrients and 2) wet/dry seasonality influence epilithon standing stocks and nutrient quality. We surveyed 18 stream locations within six watersheds that varied in nutrient and light conditions during both the wet and dry seasons on the island of Trinidad to test these questions. Additionally, we sampled four stream reaches bimonthly for three years, thinning the canopy of two of …


An Artesian Well System In Beaver Crossing, Nebraska, It's Development And Demise, Mary Lanik Apr 2010

An Artesian Well System In Beaver Crossing, Nebraska, It's Development And Demise, Mary Lanik

Department of Environmental Studies: Undergraduate Student Theses

ABSTRACT

Nebraska has a veritable wealth of groundwater. The High Plains Aquifer underlies most of the state, and within its sand and gravel deposits, many interconnected aquifers provide fresh water for a variety of uses.

One of the most spectacular examples of this resource is the artesian well. Beaver Crossing, Nebraska was once home to one of the most prolific artesian systems in the state before its demise. Founded in the 1880’s, Beaver Crossing soon became known for its many artesian wells, that provided leisure activities and supported profitable business ventures such as small farming, ice production and aquiculture. Eventually …

Distribution Of Rain Gardens In Lincoln Nebraska: Are Rain Gardens More Likely To Be Built Near Bodies Of Water, Eric Voecks

Department of Environmental Studies: Undergraduate Student Theses

Abstract Rain gardens are an important tool in reducing the amount of stormwater runoff and accompanying pollutants from entering the city’s streams and lakes, and reducing their water quality. This thesis project analyzed the number of rain gardens installed through the City of Lincoln Nebraska Watershed Management’s Rain Garden Water Quality Project in distance intervals of one-eighth mile from streams and lakes. This data shows the distribution of these rain gardens in relation to streams and lakes and attempts to determine if proximity to streams and lakes is a factor in homeowners installing rain gardens. ArcGIS was used to create …


Input-Output Analysis Of Irish Construction Sector Greenhouse Gas Emissions, Adolf Acquaye, Aidan Duffy Apr 2010

Input-Output Analysis Of Irish Construction Sector Greenhouse Gas Emissions, Adolf Acquaye, Aidan Duffy

Articles

Ireland is committed to limiting its greenhouse gas (GHG) emissions to 113% of 1990 levels over the period 2008-12 and to 84% of 2005 levels by 2020 under the Kyoto Agreement and the EU’s ’20 20’ by 2020 respectively. National policies have targeted many industry sectors but have failed to directly tackle GHG emissions associated with construction activity. This paper estimates energy and GHG emissions intensities of the Irish construction sector and subsectors and estimates its contribution to Irish national emissions. This information is used to identify and assess the impacts of policy measures which would result in a reduction …


Analysis Of Streamflow In The St. Croix River: A Hydrologic Model, Stephanie A. Kleinschmidt Apr 2010

Analysis Of Streamflow In The St. Croix River: A Hydrologic Model, Stephanie A. Kleinschmidt

Geography Honors Projects

This project assesses how streamflow is affected by anthropogenic changes to the environment, looking specifically at the St. Croix River Basin. In 2004 the United States Geologic Survey (USGS) published a report on streamflow in the St. Croix River at two gaging stations: Danbury and St. Croix Falls. The streamflow at the upstream station near Danbury, Wisconsin remained stable over time, while an increase was observed at the station in St. Croix Falls, Wisconsin further downstream. In order to evaluate this disparity, this project utilizes a GIS hydrologic model to analyze the factors expected to be influencing the flow rate. …
