flow-rate measurement in rivers under different conditions is required for river management purposes including water resources planning, pollution prevention, and flood control. this study proposed a new discharge estimation method by using a mean velocity derived from a 2d velocity distribution formula based on tsallis entropy concept. this procedure is done based on several factors which refl...
Rapid land loss in the Mississippi River Delta Plain has led to intensive efforts by state and federal agencies for finding solutions in coastal land restoration in the past decade. One of the proposed solutions includes diversion of the Mississippi River water into drowning wetland areas. Although a few recent studies have investigated flow-sediment relationships in the Lowermost Mississippi R...
Wise and sustainable uses of water resources are essential for an effective river-basin-management planning. Recent management strategy further addresses the fact that quantity and quality of water are closely interrelated, and both must be considered simultaneously for all water resources and water quality management practices. The aim of this paper is to explore the impacts of water resources...
rivers are among the most important surface water resources which have always been of significance throughout the history of mankind. this significance is due to human dependence on water for answering his needs such as agriculture, water transfer, flood control and water transportation. in the past, it was assumed that basic measures such as exploiting rivers or managing floods were only limit...
1. The language and its speakers 1.1. Sociohistorical background Saramaccan is an Atlantic creole spoken primarily in Suriname, though there are also speakers in French Guiana as well as a substantial diaspora population in the Netherlands. The fifteenth edition of the Ethnologue estimates that there are about 26,000 speakers of the languages. It is a maroon creole—that is, a creole spoken by d...

The potamodromous smallscale redfin minnow (Pseudobarbus asper) spawned in the riffle areas of the regulated Groot River, the major tributary of the Gamtoos River system, during controlled releases of water from Beervlei Dam. Water had been released at irregular intervals from this flood control dam solely for irrigating agricultural lands. Flushing flows removed accumuIated salts from riverine...
The Amazon River watershed and its associated plume comprise a vast continental and oceanic area. The microbial activities along this continuum contribute substantially to global carbon and nutrient cycling, and yet there is a dearth of information on the diversity, abundance, and possible roles of viruses in this globally important river. The aim of this study was to elucidate the diversity an...
