Fisheries Survey of the New York State Barge Canal, Knowlesville to Oneida Lake

The New York State Department of Transportation conducted a two-year fisheries survey in the New York State Barge Canal with the goal of obtaining a qualitative baseline inventory of fisheries resources. The first year examined, in addition to conducting the survey, possible dredging and spoil disposal effects on fish populations in four widewater areas between Knowlesville and Fairport (Canal Section 7) (Kucharski, 1982). The present study continued the survey to Oneida Lake (Canal Sections 5 and 6). Canal Sections 5 and 6 had never been thoroughly surveyed with the exception of a few stations in two previous studies (Sawyko, 1982; Haines and Ellis, 1977). More historical collection information was available from Canal Section 7 (see Kucharski, 1982, Appendix). A variety of habitats were sampled using electroshocking, gill and trap nets, and beach seines. The collected data were used to meet the following objectives: to identify the fish species present, to determine their range; to determine the species composition and relative abundance of species within stations, study sections, and habitat type; to determine the length frequencies of selected species; and to collect scale samples for later age and growth studies. Each station was characterized as to depth, vegetation, substrate, current, temperature, pH, dissolved oxygen, conductivity or total hardness, and secchi disc transparency

Carsharing in a small city : Ithaca Carshare's first two years.

Ithaca Carshare launched service in June 2008 as the first independent carsharing organization in New York State, offering anaffordable and reliable transportation option to the residents of the City of Ithaca and Tompkins County. During the first two yearsof operation, Ithaca Carshare registered over 800 drivers who collectively made 14,126 trips totaling nearly 250,000 miles. IthacaCarshare vehicles are scattered throughout Ithaca, where they are proximate to registered drivers. Usage is best during spring andfall seasons, when the academic institutions are in session. The majority of Ithaca Carshare members are between the ages of 20 and34, and many are affiliated with either Ithaca College or Cornell University. The organization serves members across a variety ofincome brackets, indicating the affordability of carsharing services

Climate Vulnerability and Economic Assessment for At-Risk Transportation Infrastructure in the Lake Champlain Basin, New York

The New York State Department of Transportation (NYSDOT), in partnership with The Nature Conservancy (TNC), wrote this report in fulfillment of a grant from the Federal Highway Administration\u2019s (FHWA) Climate Change Resilience Pilot Program. The purpose of the program was to pilot approaches to conduct climate change and extreme vulnerability assessments of transportation infrastructure and to analyze options for adapting and improving resilience. NYSDOT and TNC developed tools and approaches to assess vulnerability primarily focused on one asset \u2013 culverts. They evaluated vulnerability, criticality and risk, and developed a method to apply an environmental importance score to each culvert. Finally, they developed a benefits valuation approach to help decision makers prioritize infrastructure and assess when to undertake culvert replacements considering social, economic, and environmental factors

A numerical investigation on the fire response of a steel girder bridge

The response of bridges subject to fire is an under researched topic despite the number of bridge failures caused by fire. Since available data shows that steel girder bridges are especially vulnerable to fire, this paper delves into their fire response by analyzing with a 3D numerical model the response of a typical bridge of 12.20 m span length. A parametric study is performed considering: (1) two possibilities for the axial restraint of the bridge deck, (2) four types of structural steel for the girders (carbon steel and stainless steel grades 1.4301, 1.4401, and 1.4462), (3) three different constitutive models for carbon steel, (4) four live loads, and (5) two alternative fire loads (the hydrocarbon fire defined by Eurocode 1 and a fire corresponding to a real fire event). Results show that restraint to deck expansion coming from an adjacent span or abutment should be considered in the numerical model. In addition, times to collapse are very small when the bridge girders are built with carbon steel (between 8.5 and 18 min) but they can almost double if stainless steel is used for the girders. Therefore, stainless steel is a material to consider for steel girder bridges in a high fire risk situation, especially if the bridge is located in a corrosive environment and its aesthetics deserves special attention. The methodology developed in this paper and the results obtained are useful for researchers and practitioners interested in developing and applying a performance-based approach for the design of bridges against fire. © 2012 Elsevier Ltd.

Implementation of the Falling-Weight Deflectometer [Project Title from Cover]

This publication compiles materials from a training program for interpreting data produced by the falling-weight deflectometer, a device that may gradually replace previous conventional methods for analyzing the structure and condition of existing pavements. The subjects covered include pavement response (basic theory including deflection, stain, and stress), empirical and mechanistic-empirical methods of pavement design, background and characteristics of the deflectometer and its measurements, backcalculation of material properties, and applications of the instrument in the context of revised AASHTO methods for overlay design
