Flood Insurance Study, City Of Cedar City, Utah, Iron County

All U.S. Government Documents (Utah Regional Depository)

This Flood Insurance Study investigates the existence and severity of flood hazards in the City of Cedar City, Iron County, Utah, and aids in the administration of the National Flood Insurance Act of 1968 and the Flood Disaster Protection Act of 1973. This study will be used to convert Cedar City to the regular program of flood insurance by the Federal Emergency Management Agency (FEMA). Local and regional planners will use this study in their efforts to promote sound flood plain management.

Fertilization Management In Double Cropping, John H. Grove

Soil Science News and Views

Double crop systems are being widely adopted by grain and silage producers in Kentucky. The wheat-soybean grain intensive system accounts for nearly 750,000 acres of cropland in the state each year. Alternative silage systems for beef and/or dairy producers involve a fall seeded small grain (wheat, barley, triticale) that is harvested at an immature stage of growth. Immediately afterward a crop for silage (corn, grain sorghum) or grain (soybean, grain sorghum) is planted. When reduced and no-tillage management practices are used the timeliness of planting is improved and losses of surface soil moisture are minimized as the second crop starts …

Identifying Environmental Features For Land Management Decisions, Annual Report, United States, National Aeronautics And Space Administration

Land Use

This annual report outlines the major accomplishments of the Center for Remote Sensing and Cartography (CRSC) since the annual report was submitted in October 1982, with reference to the semiannual report of March 1983. The past year has been characterized by important progress in the research of digital processing techniques, completion of projects involving integrated remote sensing and environmental analysis, and interesting developments for new and continuing projects. Our computing strength is stronger than ever; we continue to rely primarily on the University of Utah Research Institute's Prime computer and NASA's Earth Resources Laboratory Applications Software (ELAS). We continue to …

Does No-Till Change Soil Management Practices?, Robert L. Blevins

Soil Science News and Views

Successful no-tilling requires a different approach to soil management practices. Since continuous no-tillage systems leave residues on the soil surface without mechanically mixing them into the plow layer and since lime and fertilizer are surface-applied, no-tilled soils have biological, chemical and physical properties contrasting with those of a plowed soil. For any crop production system to be widely accepted and used it must provide and maintain desirable physical properties of the soil, control erosion and replace nutrients removed by crops and other losses. This can be accomplished in a no-till system if proper management is used.

Natural Pastures Of The Macquarie Region Of New South Wales: Their Origin, Composition And Management, David Leslie Michaelk

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two experiments were conducted in the semi-arid (400 millimeter annual rainfall) Macquarie region of New South Wales, Australia, at the Trangie Agricultural Research Station (31° 59'S; 147° S7'E), to examine (a) the way botanical parameters can be used to separate grazing and climatic impacts on range vegetation, and (b) how this delineation affects application of range science tenets (site, condition and trend) to different pasture types.

Two range sites were studied: Site 1, a light soil type, was dominated by annual grasses, legumes and forbs, whereas perennial grasses (mainly Chloris acieularis and Chloris truncata) dominated the heavy soils of …

Visual Impacts Of Forest Management Activities: Findings On Public Preferences, United States Department Of Agriculture, Forest Service

Forestry

A major concern of forest land managers is the visual impact that activities such as timber harvest, road building, and mining have on the forest landscape. Management of the visual resource is a regular part of planning on National Forests, and many other public and private forest land managers are increasing their efforts to protect and enhance this resource. The Forest Residue and Harvesting Research Program at the Intermountain Station includes studies of the impact of harvest and roading activities on visual quality. Preliminary results were reported earlier (Schweitzer, Ullrich, and Benson 1976). This report updates earlier findings and presents …

Interior West Watershed Management, United States Department Of Agriculture, Forest Service

Water

Habitat type classification systems are reviewed for potential use in watershed management. Information on climate, soils, and vegetation related to the classifications are discussed. Possible cooperative applications of vegetation and habitat type classifications to watershed management are explored.

Mass Marking Of Mosquitofish: Preliminary Results, Bruce Vondracek, Wayne A. Wurtsbaugh, Joseph J. Cech Jr.

Watershed Sciences Faculty Publications

Three marking techniques were tested to determine their applicability for mosquitofish. Tetracycline drugs and DC Ar administered in the diet successfully marked laboratory-cultured mosquitofish, but exposure to direct sunlight in outdoor tanks resulted in the rapid disappearance of the marks. Preliminary data on fluorescent marks from a polystyrene pigment in a melamine-sulfonamide-formaldehyde resin forced into the dermal ,tissue with compressed air are more promising.

A t an optimal deliver pressure of 7.3 m Hg (140 p.s.i.) and spraying time of 15 sec., marking percentage is maximized and fish mortality is minimized. Mark retention time was up to 80 days in …

Computer Simulation Of The Hydrologic And Salinity Flow Systems Within The Bear River Basin, Robert W. Hill, Eugene K. Israelsen, J. Paul Riley

Reports

Accompanying the increased use of water resources is an increases accumulation of chemical pollutants. Te prevent degradation of the water resources beyong useful limits, pollution inputs from additional uses must be quite accurately predicted prior to implementation of the new use. The model described in this report was formulated to provide the required predictive capability for the Bear River Basin. Modeling concepts of the hydrologic system are based upon the development of basin relationships describing the hydrologic processes which are linked together by the countinuity-of-mass principle. The salinity flow system is then linked to the hydrologic system based on the …

A Soil And Vegetation Inventory And Analysis Of Three Nebraska Sandhills Range Sites, Donald F. Burzlaff

Nebraska Agricultural Experiment Station: Historical Research Bulletins

This study was undertaken to inventory the soils and vegetation of certain areas of the Sandhills and to seek edaphic characteristics that may be the limiting factor in the distribution of various plant species. Information of this nature will permit formulation of more accurate management practices because of a refinement in delineation of range sites.
