An analytical solution is presented for the nonlinear pressure-flow relationship of deformable passive valves, which are formed by bonding a deformable film over etched channels separated by a weir. A fluidic pathway connecting the channels is opened when the upstream pressure creates a tunnel along a predefined narrow strip where the film is not bonded to the weir. When the width of the strip ...

abstract disc infiltrometer is one of those devices that used in recent years in measurement of hydraulic conductivity of entire soil. in order to analyze the data taken by disc infiltrometer a variety of methods based on wooding’s base analyze have been introduced. the objective of this study was to compare the performances of ankeny and weir methods for predicting soil hydraulic properties us...

For continuous monitoring of river water quality , this study assesses the potential of using artificial neural networks (ANNs) for modeling the event-based suspended sediments concentration (SSC) in Jiasian diversion weir in southern Taiwan. The hourly data collected include the water discharge, turbidity and SSC during the storm events. The feed forward backpropagation network (BP), generaliz...

Evidence from the probability learning literature indicates that when presented with simple situations that require making predictions, adults tend to probability match whereas children are likely to show maximization (Stevenson & Weir, 1959; Weir, 1964). The reason for this developmental difference is not fully understood, but one possibility investigated here is that children have fewer resou...

INTRODUCTION: The White River is a mountainous river with head waters on Mount Rainier. The Fish Barrier Structure on the White River serves as a collection point of migratory fish. Operators at the structure collect the fish and transport them upstream of Mud Mountain Dam. Currently, the fish barrier uses a weir to create a head differential, which stops the passage of the migrating fish. Howe...

Intraspecific variation in personality traits is increasingly recognized as an important determinant of invasion success and associated with the dispersal ability several invasive species. However, previous studies have focused on species through continuous habitats, despite high levels anthropogenic fragmentation modern environments. This study investigated how influences behaviour aquatic at ...

Abstract Silver Carp Hypophthalmichthys molitrix have expanded their range to encompass most of the Mississippi River basin, including much Missouri River. However, there is a paucity information concerning in especially tributaries. Little known about how function these tributaries or connectivity with main‐stem river can influence population demographics within either system. The Kansas tribu...
