Environmental history is the study of human interaction with the natural world over time, emphasising the active role nature plays in influencing human affairs and vice versa.. Environmental history first emerged in the United States out of the environmental movement of the 1960s and 1970s, and much of its impetus still stems from present-day global If you have questions or comments concerning the Rightslink service, please contact: To request permission to distribute a PDF, please contact our Customer Service Department at 800-624-6242 for pricing. The natural slope of the flood plains is often very small, and little fall (or head loss) is permissible in the culverts. The CO 2 produced for the manufacture of structural concrete (using ~14% cement) is estimated at 410 kg/m 3 [7][2], For existing culverts which have experienced degradation, loss of structural integrity or need to meet new codes or standards, rehabilitation using a reline pipe may be preferred versus replacement. Culverts that offer adequate aquatic organism passage reduce impediments to movement of fish, wildlife, and other aquatic life that require instream passage.
