Final report : ecological assessment of a wetlands mitigation bank (phase II: continued restoration efforts)( Book )

4 editions published in 2002 in English and held by 38 WorldCat member libraries worldwide

The overall objective for the Tulula Wetlands Mitigation Bank has been to restore the functional and structural characteristics of the wetlands. Specific restoration objectives of this Phase II study included: 1) determining the success of stream realignment by evaluating the geomorphology of the new channel before and after water release; 2) evaluating changes in ecosystem structure and function associated with plant community succession in planted and unplanted portions of the floodplain in response to restored hydrology; and 3) evaluating wildlife use of the site in response to changing hydrologic conditions (amphibians) and plant community succession (birds). A meandering channel (1.2 miles in length) was constructed across the floodplain and a portion of the constructed channel was connected to the existing Tulula Creek in fall 2001. Six random channel segments were used for measurements of stream geomorphology and after four months of water flow few differences were noted for channel morphology, partially reflecting the lack of substantial precipitation events since completion of the constructed channel. The hydrology of Tulula has been influenced by a regional drought that began in the summer of 1998 and the lack of precipitation has made hydrology assessment difficult at Tulula. Substantial natural regeneration of woody plants is occurring in the fairways at Tulula. The authors inventoried regenerating stems in a portion of one fairway, and found that 42% were shrubs, and 58% were sapling trees. Species diversity was much higher for shrubs than for trees, as 93% of all regenerating tree stems were red maple. When the North Carolina Department of Transportation (NCDOT) commenced restoration activities, spoil was removed from one fairway, and the original hydric soils and accompanying seed bank were exposed. In this area, coverage by one group of wetland plants (rushes) increased significantly between 2000 and 2001. Amphibians rapidly colonized constructed vernal ponds, and the number of species that utilize these as breeding sites averaged about 50% higher than that of reference ponds. The survivorship and output of wood frog and spotted salamander juveniles have declined since pond construction, in part due to the accumulation of predators in ponds, the outbreak of a virus pathogen, and premature pond drying associated with drought. Bird species richness in 2002 was the highest of the four years that surveys have been conducted, with 39 species recorded. Relative bird abundance increased 49% (215 to 321 birds) from 2000 to 2002. Four species, American Robin, Red-winged Blackbird, Northern Cardinal, and Song Sparrow, increased in relatively large numbers, accounting for 50% (53 birds) of the total increase in relative abundance in 2002

Performance evaluation of fine graded Superpave mixtures for surface courses by N. Paul Khosla( Book )

3 editions published in 2001 in English and held by 34 WorldCat member libraries worldwide

Strategic Highway Research Program (SHRP) A407 recommends that aggregate gradations pass below the restricted zone as traffic level increases. This study investigated the use of natural sand in the fine and coarse gradations for the surface course mixtures. The mixtures were designed using the SUPERPAVE mix design approach and were evaluated for their performance in terms of resistance to rutting, fatigue and moisture damage. In addition, the accelerated performance of these mixtures was also evaluated using the Asphalt Pavement Analyzer
Southeast regional fatal study : a causal chain analysis in North Carolina by James Kevin Lacy( Book )

2 editions published in 2002 in English and held by 34 WorldCat member libraries worldwide

This project completed the North Carolina portion of the pooled fund Southeast Fatal Analysis Project. In addition to completing this portion of the causal chain analysis for North Carolina crashes, the project developed a comprehensive list of candidate safety countermeasures likely to be effective in reducing both the number and severity of fatal crashes on two-lane rural roads in North Carolina. The list includes countermeasures ranked according to their expected influence on fatal crash frequency and severity for two-lane rural roads
Prototype demonstration of a geographic information system application for the seasonal analysis of traffic data, development of seasonal factors and seasonal adjustment of roadways by Shannon M McDonald( Book )

4 editions published in 1999 in English and held by 33 WorldCat member libraries worldwide

The Traffic Survey Unit plans to establish a methodology in which it can assign each Portable Traffic Counter station a seasonal group profile through a means of statistical and geographical analysis. An ArcView Geographic Information System (GIS) application was programmed to allow the traffic survey sites to be analyzed by their spatial nature as well as by their statistical profiles. This program was created using the Avenue programming language. The program offers a user-friendly GIS interface that can aid analysts with updating the current seasonal groupings for traffic survey points across North Carolina. The user is able to select a site and display an attribute table listing its current seasonal assignment, its new seasonal assignment based on the best "best guess" as determined by the statistical analysis, and all the "best guesses" determined by that analysis. The user is also able to summon displays of the seven Seasonal Profiles, and the graphs and charts produced by the statistical analysis. Finally, the user is able to update the new seasonal assignment based on the results of the statistical analysis and its geographical proximity to the other stations, highways, and municipalities
Motorists' perception of work zone safety( Book )

4 editions published in 1999 in English and held by 33 WorldCat member libraries worldwide

Highway work zones create potential hazards because motorists are confronted with unexpected and often confusing situations. The objective of this research study was to examine motorists' perceptions, opinions, expectations and other psychological factors, which influence their driving activity in highway work zones. The study was carried out in two parts: an opinion survey and focus groups. A two-page questionnaire was distributed to 2,246 automobile and truck drivers
Stone mastic asphalt mixture study for bituminous concrete courses : a design and performance evaluation by N. Paul Khosla( Book )

3 editions published in 1996 in English and held by 32 WorldCat member libraries worldwide

The primary objectives of this study were: (1) To evaluate the performance of stone mastic asphalt (SMA) mixes by performing fatigue tests, resilient modulus tests and creep tests; and (2) To input the resilient modulus, creep and fatigue data into the VESYS III-A pavement performance prediction model to determine the performance of the SMA mixes compared to the performance of the conventional, dense-graded asphalt mixes. Three surface course mixes were designed using the following mastic types: (1) Cellulose fibers; (2) Mineral fibers; and (3) Polymerized asphalt (Novophalt)

Low light as a possible impediment to river herring migration by Mary L Moser( Book )

2 editions published in 1999 in English and held by 30 WorldCat member libraries worldwide

Pipe and box culverts are economical alternatives to bridge construction over small water bodies; however, low light levels inside these structures may prevent adult river herring from passing through them on the way to historical spawning areas upstream. The effects of pipes and culverts on herring migration behavior were investigated using gillnet sampling, acoustic observations, and experimental field manipulations

Simulation of water-surface elevations and velocity distributions at the U.S. Highway 13 bridge over the Tar River at Greenville, North Carolina, using one- and two-dimensional steady-state hydraulic models by C. Russell Wagner( )

1 edition published in 2007 in English and held by 0 WorldCat member libraries worldwide

The use of one-dimensional hydraulic models currently is the standard method for estimating velocity fields through a bridge opening for scour computations and habitat assessment. Flood-flow contraction through bridge openings, however, is hydrodynamically two dimensional and often three dimensional. Although there is awareness of the utility of two-dimensional models to predict the complex hydraulic conditions at bridge structures, little guidance is available to indicate whether a one- or two-dimensional model will accurately estimate the hydraulic conditions at a bridge site. The U.S. Geological Survey, in cooperation with the North Carolina Department of Transportation, initiated a study in 2004 to compare one- and two-dimensional model results with field measurements at complex riverine and tidal bridges in North Carolina to evaluate the ability of each model to represent field conditions. The field data consisted of discharge and depth-averaged velocity profiles measured with an acoustic Doppler current profiler and surveyed water- surface profiles for two high-flow conditions. For the initial study site (U.S. Highway 13 over the Tar River at Greenville, North Carolina), the water-surface elevations and velocity distributions simulated by the one- and two-dimensional models showed appreciable disparity in the highly sinuous reach upstream from the U.S. Highway 13 bridge
