Maximum equilibrium scour depths, equilibrium scour volumes,
and induced equilibrium movements at isolated obstacles on river
beds were investigated in clear-water scour. The research was
achieved by a systematic flume study based on the results of
dimensional analysis of local scour.
The main tested obstacles for local scour were cubes....
Natural resource data are typically non-linear and complex, yet modeling methods often utilize statistical analysis techniques, such as regression, that are insufficient for use on such data. This research proposes an innovative modeling method based on pattern recognition techniques borrowed from the field of machine learning. These techniques make no...
This research examines the downstream fining phenomenon as it operates in coastal gravel-bed rivers of Oregon. Downstream fining is a change in bed composition toward smaller sediment sizes in the downstream direction. Changes in stream flow discharge and channel slope affect the rate of bed-load transport, thereby altering the downstream...
This research analyzes the effects of islands on river process and the effects river processes have on island formation. A fluvial island is defined herein as a land mass within a river channel that is separated from the floodplain by water on all sides, exhibits some stability, and remains exposed...
Object oriented programming features information hiding and encapsulation, meaning that 1) each object hides the the implementation details tram access from outside and only a set of methods (interface routines) are visible outside of the object, and 2) changes to the implementation of the object do not require changes to...
An evaluation was made on the nutritive value of tropical forages
and by-product feeds for rabbit production. Digestibility of nutrient
fractions, feed preferences, growth, combination of forages, supplementation
of micro and macro nutrients and/or effects of drying temperature
on the quality of four groups of forages, namely woody legumes
(WL),...
Recent experimental and theoretical work has examined the possible genetic causes of senescence. These are reviewed, and four types of factors are found to be responsible for the evolution of senescence and age specific fecundity curves: 1. Age specific mortality schedules, 2.Density dependent factors, 3. Density independent factors, 4. Random...
