This book was released on 1984 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 25 borrow pits sampled were distributed along the Mississippi River from New Madrid, Missouri, to near Lutcher, Louisiana. Data on fishes, macrobenthos, water quality, and sediments were collected once in the summer of 1981; topographic surveys of each borrow pit were conducted in 1982. Results of this investigation indicated that main stem levee borrow pits along the Lower Mississippi RIver support abundant and moderately diverse fish and macroinvertebrate populations. Total fish standing stock averaged 600 lb/acre; macroinvertebrate total density and standing stock averaged 2967 organisms/sq m. and 851 mg dry weight/sq m. respectively. Gizzard shad, buffalo, carp, and threadfin shad were the most abundant fishes, but significant numbers of white crappie, sunfishes, and catfishes were also present. The phantom midge, Chaoborus punctipennis, the midge Tanypus stellatus, and tubificid worms were the most abundant macroinvertebrates. Step-wise regression analyses revealed that the duration of annual borrow pit flooding by Mississippi River waters was the single most important positive factor affecting fish and macrobenthos abundance in the borrow pits; mean borrow pit depth, Volume Development Index (a depth factor), and Shoreline Development Index were also significant factors influencing the abundance of some fish and macrobenthos species.

Cobb and published by . This book was released on 1986 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil used to construct the main stem levees is obtained from adjacent land, usually between the levee and the river. Surface depressions resulting from excavation of such material are known as borrow pits. A series of borrow pits is generally found along the riverward toe of the main stem levee system throughout its length. The Levee Borrow Pit Investigation (LBPI) was designed to provide data on fishery, benthos, wildlife, vegetation, physical, and chemical aspects of main stem levee borrow pits. Specific objectives of the LBPI are: (1) To develop an inventory of wildlife and fishery resources of the main stem levee system borrow pits; and (2) To formulate environmental design considerations for main stem levee system borrow pits. The first fieldwork of the LBPI included fish and aquatic sampling by the US Army Engineer Waterways Experiment Station (WES) from June through August 1981. Topographic surveys of selected pits were conducted by the US Army Engineer District (USAED), Vicksburg, in 1982. Wildlife surveys were carried out by WES on a seasonal basis for 2 years from December 1981 to October 1983. This report presents partial results of the wildlife study conducted as part of the LBPI.

Aggus and published by . This book was released on 1986 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmentally important physical features of main stem levee borrow areas along the Lower Mississippi River are identified and presented as design considerations. These design considerations were developed for the Mississippi River Commission for possible use in design and construction of the Mississippi River levees portion of the Mississippi River and Tributaries Project. Routine, relatively inexpensive environmental measures and more complex, costly measures are identified and discussed. Environmental measures discussed include borrow pit size, depth, shape, and vegetation and cover for both fish and wildlife. A review of the literature relating to the ecological characteristics of borrow pits and similar water bodies is presented. (Author).

Buglewicz and published by . This book was released on 1988 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twenty-five borrow pits along the main stem levee system of the Lower Mississippi River were investigated with regard to selected physical, chemical, and biological resources as part of the Lower Mississippi River Environmental Program. Objectives of the levee borrow pit investigation are to develop an inventory of environmental resources of the borrow pits and to develop environmental design criteria for borrow pits to be used during levee construction. The 25 borrow pits were located between the levees along the Mississippi River from near New Madrid, Missouri (River Mile (RM) 877) to near Belmont, Louisiana (RM 151). Data on fishes, water quality, macrobenthos, and sediments were collected during the summer of 1981. A topographic field survey of each borrow pit was conducted during 1982. A vegetation survey was conducted from 1981 to 1983 as part of a companion study of bird and mammal use. Vegetation data are summarized in this report. Levee borrow pits range in size from one acre ponds to lakes of 50 or more acres. Traditional indicators of environmental quality based on morphological characteristics do not generally fit these unique aquatic basins. The borrow pit basins are generally shallow with most of the bottom in the photic zone. Physico-chemical indicators suggest a productive aquatic habitat. Although the data are survey in scope, it represents the first time a large number of borrow pits representing the entire Lower Mississippi River have been described and compared. (fr).

Book excerpt: The international journal Ecohydrology & Hydrobiology (E&H) has been created to promote the concept of Ecohydrology, which is defined as the study of the functional interrelations between hydrology and biota at the catchment scale. Ecohydrology extends from the molecular level to catchment-scale processes and is based on three principles: • framework (hydrological principle) - quantification and integration of hydrological and ecological processes at a basin scale; • target (ecological principle) - necessity of enhancing ecosystem absorbing capacity and ecosystem services; and • management tool (ecological engineering) – the use of ecosystem properties for regulation the interplay between hydrology and biota. The journal encourages the submission of manuscripts which adopt an integrative approach to aquatic sciences, explaining ecological and hydrological processes at a river-basin scale or propose practical applications of this knowledge. It will also consider papers in other hydrobiological fields. Especially welcome are papers on regulatory mechanism within biocenosis and the resistance and resilience of freshwater and costal zones ecosystems. There is no page charge for published papers. All submitted papers, written exclusively in English, should be original works, unpublished and not under consideration for publication elsewhere. All papers are peer-reviewed. The following types of papers are considered for publication in E&H: • original research papers • invited or submitted review papers, • short communications
