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...

17 Globally, populations of diadromous anguilliform morphotype fish, such as eel and 18 lamprey, have experienced substantial declines, partly as a result of habitat 19 fragmentation caused by river infrastructure. In the UK, a new configuration of 20 hydraulically unobtrusive bristle pass (side-mounted and vertically oriented) has been 21 developed to help upstream moving European eel (Anguill...

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...

Evidence provided by Weir and Smith, particularly the findings from the National Health and Nutrition Examination Survey (NHANES), leads us to conclude that an increase in arthritis prevalence during the 1990s in the United States is probable, but the trend is likely overstated in the Health and Retirement Study (HRS). We show that a mistake in our earlier method does not change substantively o...

This work is mainly focused on improving the principle characteristics of RMPA. Here design of rectangular SRR based metamaterial structure is proposed, which has been superimposed on RMPA at a height of 3.2mm from its ground plane. The resonating frequency of the proposed antenna is 1.896GHz. Simulation results are suggested that the impedance bandwidth of RMPA with proposed metamaterial struc...

in order to improve the performance of irrigation networks, provide higher flexibility levels and improve water delivery methods, application of automatic control systems is suggested. in the coarse of the present study, a mathematical model of automatic pivot weir as based on pid control logic in combination with icss hydrodynamic model is developed. the developed model was tested under high f...
