The ENFA analysis indicated high-suitability locations were in or near deep water during both high and low river stages. During high river stages, high-suitability locations were near island tip habitat, deep water, and steep bottom slope and far from main channel habitat. During low stages, ...
The use of retro- and scenario-modeling to assess effects of 100+ years river of engineering and land-cover change on Middle and Lower Mississippi River fl... modeling to assess effects of 100 + years river of engineering and land cover change on middle and lower Mississipi flood stages, ...
At low water river stages, isolated dike pools bordered by bars are formed, creating distinct aquatic habitats which are quite variable in size and depth. Fish and water samples collected in two such dike pools as well as from the adjacent river border wee used to determine the importance of...
Nutrient Biogeochemistry During the Early Stages of Delta Development in the Mississippi River Deltaic Plain Nutrient biogeochemistry associated with the early stages of soil development in deltaic floodplains has not been well defined. Such a model should follow ... KM Henry,RR Twilley - 《Ecosyst...
In the lower Amazon River, suspended sediment is stored during rising stages of the river and resuspended during falling river stages. The storage and resuspension in the reach are related to the mean slope of the flood wave on the river... RH Meade,T Dunne,JE Richey,... - 《Science》 ...
Seasonally, the percentage of carbohydrates in the lower Mississippi River appeared to increase during high discharge periods (e.g., through December 2001 to June 2002 and in February 2003) (Figure 6c). In the Pearl River, both carboxyl C and % aromaticity were higher during flooding stages ...
The Hehuashan Pb–Zn deposit is dominated by two main mineralization stages, including early stage mineralization (composed of breccia type ore bodies) and late mineralization (composed of massive type ore bodies). The Pb–Zn ore rocks of early stage contains numerous organic maters such as ...

Total aquatic habitat surface area ranged from 10,971 acres at a 0-foot LWRP river stage to 25,778 acres at a stage of +15 feet LWRP for pool areas, and from 14,404 acres to 23,599 acres at these river stages in sandbars associated with dike systems. These data were based on ...
