Book excerpt: The Chesapeake and Ohio Canal National Historical Park is 184.5 mi long and extends from Washington, D.C., to Cumberland, Md. The canal passes through three physiographic provinces including the Piedmont, Valley and Ridge, and the Blue Ridge; the map area also includes rocks of the Coastal Plain and Appalachian Plateaus provinces. Each province contains unique packages of rocks that influenced the character of the canal and towpath. The ages of the bedrock encountered along the length of the park range from Mesoproterozoic to Jurassic and represent a variety of tectonic and depositional environments. The different rock types and surficial deposits dictated the various construction methods for the canal, which was excavated in Quaternary flood-plain deposits as well as through bedrock. The ancient course of the Potomac River and the deposits it left behind also influenced the location of the canal and towpath. The engineers made good use of the many rock types to construct the locks, dams, aqueducts, and culverts that guided water from the Potomac River into the canal and maintained the water level as canal boats traveled between higher elevations in western Maryland to sea level in Washington, D.C. The canal and towpath provide a unique transect across the central Appalachian region for examining the rich geologic diversity and history.

Download or read book Highlights of the Geology and Engineering of the Chesapeake and Ohio Canal written by William E. Davies and published by American Geophysical Union. This book was released on 1991-01-08 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Field Trip Guidebooks Series, Volume 206. The Chesapeake and Ohio Canal National Historical Park offers an opportunity to examine most of the rock formations and geologic structures typical of the Potomac Appalachians as well as many features of civil engineering related to the C&O Canal. This can be done in a safe and leisurely manner along the canal towpath. Several plants along the canal are to be avoided. Poison Ivy growth is rampant. The plant grows as low ground cover, as a bush and as a vine. Poison Ivy is characterized by leaves in clusters of three. Contact of the skin with the plant or with its secretions on clothing, shoes and other personal objects can result in a severe skin irritation that lasts up to a month. Another annoying plant is the nettle. On contact, even where the skin is covered by clothing, this plant can inject a toxin that numbs the skin for several hours leaving a persistent itch for a day. During the warm season ticks, which carry spotted fever and Lyme disease, are common throughout the area. It is prudent after being in the field to make a careful check to see if ticks are on the body and remove them. Two poisonous snakes are in the region. The Timber Rattler is a dangerous viper but is seldom encountered. It is not aggressive and generally moves off unless cornered or surprised. It occurs mainly in sandstone areas. The Copperhead is common in all parts of the area. Its bite causes injury but it is seldom fatal to adults.

Download or read book Urban Stormwater Management in the United States written by National Research Council and published by National Academies Press. This book was released on 2009-03-17 with total page 611 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.

Book excerpt: Biology and Control of Aquatic Plants: A Best Management Practices Handbook is the fourth edition of a handbook produced by the not for profit Aquatic Ecosystem Restoration Foundation (AERF). The mission of the AERF is to support research and development which provides strategies and techniques for the environmentally and scientifically sound management, conservation and restoration of aquatic ecosystems. One way the Foundation accomplishes this mission is by producing this handbook to provide information to the public regarding the benefits of aquatic ecosystem conservation and aquatic plant management. The first, second and third editions of this handbook became some of the most widely consulted references in the aquatic plant management community. This fourth edition has been specifically designed with water resource managers, water management associations, homeowners and customers and operators of aquatic plant management companies and districts in mind. Our goal in preparing this handbook is to provide basic, scientifically sound information to assist decision-makers with their water management questions.
