Pages : 68
Book Description
Fresh groundwater in the Mississippi embayment can be found in alternating formations of sand, silt, and clay. The uppermost of these formations is the Mississippi River Valley alluvial aquifer (alluvial aquifer), which can provide well yields of 300 to 2,000 gal/min. The alluvial aquifer exists at land surface and covers much of the embayment area within the Mississippi Alluvial Plain.

Pages : 403
Book Description
This paper highlights the role of agriculture in the American economy and society over time and points to farmer historical and contemporary responses to varying climatic conditions. It indicates the importance of water as an input to agricultural production and identifies possible impacts of climate change on access to water. It then summarizes a set of eleven papers from an NBER research project on water, climate change, and the agricultural sector.
Breakfast Cereals and How They Are Made

Languages : en
Pages : 478
Book Description
Breakfast Cereals and How They Are Made: Raw Materials, Processing, and Production, Third Edition, covers the transformation of a cereal grain across the supply chain with oversight of the entire lifecycle – from ingredient, to finished product. The book provides essential Information for food product developers on the effect of ingredients and process conditions on breakfast cereal quality. All aspects of the processing of cereals grains into finished products is covered, from batching and cooking, toasting and tempering, coating, the inclusion of additional ingredients, and packaging information. In addition, the book covers the chemistry and economics of cereal crops. Essential reading for all product developers working in the cereal industry, this book will also be of interest to academic researchers and postgraduate students in both cereal science and food processing. - Provides an up-to-date, end-to-end overview of the production process of cereal products - Edited by active cereals researchers working in industry, with experts from both academia and industry supplying content - Includes essential information on both ingredients and processes in the production of breakfast cereals - Discusses materials, cooking and packaging - Includes nutrition, quality and safety
Characterizing Spatial and Temporal Changes and Driving Factors of Groundwater and Surface-water Interactions Within the Mississippi Portion of the Mississippi Alluvial Plain

Book Description
The Mississippi Alluvial Plain, a robust agricultural region in the South-Central United States, provides commodities across the United States and around the world. Water for irrigation, which is necessary due to irregular rainfall patterns during the growing season, is withdrawn largely from the Mississippi River Valley Alluvial aquifer, one of the most intensely used aquifers in the United States. The groundwater-dependent region has observed recent declines in groundwater and streamflow levels, raising concerns about the availability and use of fresh-water resources. Declining water levels have prompted investigation into the current understanding of groundwater and surface water interaction. Previous research does not adequately quantify the unobservable exchange of water between surface-water bodies and the underlying aquifer. This research was designed to advance the current understanding of the interaction between groundwater and surface water through the quantification of spatial and temporal trends in streamflow and groundwater level changes and the use of high-resolution spatial estimates of streambed hydraulic conductivity. Changes in streamflow and groundwater levels were quantified with the use of hydrograph-separation techniques and trend analyses. High-resolution estimates of streambed hydraulic conductivity were found through the correlation of waterborne continuous resistivity profiling data to hydraulic conductivity and streambed hydraulic conductivity estimates were incorporated into the existing Mississippi Embayment Regional Aquifer Study (MERAS) groundwater-flow model. Site-specific empirical relationships between resistivity and hydraulic conductivity were developed with near-stream borehole geophysical logs to improve model estimates of streambed hydraulic conductivity. Results of the quantification of changes in streamflow and groundwater levels suggested agricultural groundwater withdrawals for irrigation to be the primary source of groundwater-level declines. Results from the incorporation of high-resolution estimates of streambed hydraulic conductivity showed that the existing groundwater-flow model is sensitive to changes in streambed hydraulic conductivity, which may impact model accuracy. The incorporation of streambed hydraulic conductivity estimates derived from site-specific empirical relationships impacted MERAS model water-budget estimates. Information gained from this research will be used to improve the existing groundwater-flow model, which acts as a decision-support tool for water-resource managers at state and local levels to make informed water-use decisions for the conservation of fresh-water resources for sustainable agricultural irrigation practices.
