Book excerpt: Excerpt from Mulches for Wind and Water Erosion Control This report deals with procedures for establishing various kinds of protective mulch and for establishing and maintaining permanent vegetation. The word mulch means any substance, such as straw, hay, paper, gravel, organic or inorganic film, brush Spread upon the ground, or produced and killed or allowed to die and left on the ground as a stubble mulch, or formed and left on the ground as a layer of clods or dust, for the purpose of protecting the soil from erosion or the plants from heat, cold, or drought. The limitation on what is called a mulch is not the kind of material from which it is derived but that it be dead when left or placed on the ground. On the other hand, the term permanent vegetation means perennial vegetation such as grasses, shrubs, or trees growing on the land. Perma nent vegetation is a living cover, whereas mulch is a dead cover. A mulch may be tempo rary such as dead vegetation, or permanent such as a layer of stones or gravel. This report includes information on stabilization of level and sloping ground, but not waterways The information was obtained in part from a series of experiments started in 1959 on contract with the Bureau of Yards and Docks, Department of the Navy. Explanations of various research procedures and data pertaining to the contracted series of experiments are contained in other reports 9, A portable wind tunnel was used to determine the effectiveness of the various mulching treatments under field conditions (fig. Limited information also was obtained on the relative effectiveness of some of the treatments against erosion by water. From results of the wind tunnel tests, the wind erosion climatic factor (4) and the universal wind erosion equation (1) were used to estimate the relative quantities of mulch required in various sections of the United States. An effective wind erosion control treatment is considered as one that will resist an 85-mile-per-hour wind as measured at so-foot height.

This book was released on 2018-01-10 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Control of Wind Erosion in the Sandy Lands of the Southern High Plains of Texas and New Mexico Wind erosion occurs when high winds come in contact with loose, unprotected soil. Particles of medium and fine sand begin to move across the soil surface in a series of bounces or by rolling or creeping. Where they strike unprotected soil they loosen other particles which are then swept across the ground surface and cause-still further erosion. Finer particles are sometimes carried high into the air and may float for days before settling. The damage done by wind erosion has serious short and long-term effects. The most notable short-term effect is that of reducing or eliminating stands of crops. One storm can completely destroy young cotton. A visible effect of erosion is the piling up of sand or silt on highways, railroad rights-of-way, and around buildings on farms and in urban areas. This material must be removed at great expense. Another visible effect of wind erosion is the duning of sand in cultivated fields, making them impractical to till for crop production. Perhaps the most serious effect of wind erosion, however, is sel dom noticed. This is the removal of clay and organic matter from sandy soils. The soil is left not merely more susceptible to wind erosion than before; the materials which are of major importance in storing and eventually releasing moisture and nutrients are gone from the plowed layer. The finer the texture, the more serious the loss, since organic matter (thus nitrogen) is stored in the surface 6 or 7 inches of the soil. Removal of a part or all of this horizon usually reduces the inherent productivity of the soil. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book Urban Runoff Quality Management written by Water Environment Federation and published by ASCE Publications. This book was released on 1998-01-01 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This manual comprises a holistic view of urban runoff quality management. For the beginner, who has little previous exposure to urban runoff quality management, the manual covers the entire subject area from sources and effects of pollutants in urban runoff through the development of management plans and the design of controls. For the municipal stormwater management agency, guidance is given for developing a water quality management plan that takes into account receiving water use objectives, local climatology, regulation, financing and cost, and procedures for comparing various types of controls for suitability and cost effectiveness in a particular area. This guidance will also assist owners of large-scale urban development projects in cost-effectively and aesthetically integrating water quality control to the drainage plan. The manual is also directed to designers who desire a self-contained unit that discusses the design of specific quality controls for urban runoff.
Download or read book Principles of Soil Conservation and Management written by Humberto Blanco-Canqui and published by Springer Science & Business Media. This book was released on 2008-09-16 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Principles of Soil Management and Conservation” comprehensively reviews the state-of-knowledge on soil erosion and management. It discusses in detail soil conservation topics in relation to soil productivity, environment quality, and agronomic production. It addresses the implications of soil erosion with emphasis on global hotspots and synthesizes available from developed and developing countries. It also critically reviews information on no-till management, organic farming, crop residue management for industrial uses, conservation buffers (e.g., grass buffers, agroforestry systems), and the problem of hypoxia in the Gulf of Mexico and in other regions. This book uniquely addresses the global issues including carbon sequestration, net emissions of CO2, and erosion as a sink or source of C under different scenarios of soil management. It also deliberates the implications of the projected global warming on soil erosion and vice versa. The concern about global food security in relation to soil erosion and strategies for confronting the remaining problems in soil management and conservation are specifically addressed. This volume is suitable for both undergraduate and graduate students interested in understanding the principles of soil conservation and management. The book is also useful for practitioners, extension agents, soil conservationists, and policymakers as an important reference material.

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.
