Watershed Erosion
Scientific agricultural planning requires knowledge of the relations between soil and water that cause soil loss, and of the procedure to reduce such losses on cropland. This paper presents...
Total Sediment Loads of Tropical Rivers
Unmeasured and total sediment discharges were computed for 107 sets of data from the Amazon and Orinoco Rivers and their major tributaries. Unmeasured loads were generally small except...
Bed Sediments Size Changes, Atchafalaya River
During low flows of 1989 and 1991, we collected bed sediment samples from the thalwegs of the Mississippi River from Cairo, Illinois, to Head of Passes and along the Atchafalaya River...
Bank Stability Analyses Versus Field Observations
The concept and process of stream bank stabilization design through the development and use of limiting stability curves for the comparison of existing bank height/angle combinations to...
Video Analysis of Gravel Saltation
Experimental results concerning saltation characteristics of gravel particles in a movable bed channel are analyzed by using video imaging techniques. Ensemble averaged values of saltation...
Drag Characteristics of Coarse Sediment in Clay Suspensions
Drag characteristics of spherical particles in clay suspensions, such as coarse sediment in hyperconcentrated flows, has been analyzed by using a limited data available in the literature....
Rheometry of Natural Sediment Slurries
Recent experimental analyses of natural sediment slurries yield diverse results yet exhibit broad commonality of rheological responses under a range of conditions and shear rates. Results...
Prediction of Filtrate Turbidity by Parameter Estimation
In order to operate the rapid sand filter in response to the time variation of effluent quality, a model and a procedure to predict the filtrate quality of rapid sand filters have been...
Scour Inspection Using Ground Penetrating Radar
This paper examines the capabilities of Ground Penetrating Radar (GPR) for river bed scour inspection based on a study carried out by Clarkson University, Potsdam, New York in association...
New Canadian Provisions Related to the Design of Composite Beams
In this paper, the new provisions in CAN/CSA-S16.1-M89 for the design of composite beams, together with reasons for changes, are discussed. Some of the new provisions reflect results of...
Shear Connection in Composite Beams
This paper considers the influence of the shape of the deck profile on the shear connection of composite beams. It was found that the existing strength reduction factor can be unconservative...
Modern Design Concept for Composite Slabs with Ductile Behaviour
Numerous tests with different types of composite slabs have been carried out in the laboratory for constructional engineering of the University of Kaiserslautern, Germany in order to determine...
Connection of Grouted Tubular Insert Piles to Soil
Force transfer between offshore production jackets and tubular piles is effected by weld bead shear connectors, acting within the grout filled annulus between the piles and pile sleeves...
Design of Shear Connectors in Composite Bridge Beams
A new approach is described for the design of stud shear connectors, in composite steel and concrete beams that are subjected to vehicular loads, which allows for the interaction between...
Design of Composite Slabs for Vertical Shear
Three major modes of failure should be considered in the design of the positive moment regions of composite slabs incorporating profiled steel sheeting, viz.: flexure, longitudinal slip...
Investigation of Corners and Joints Applied to a Steel-Concrete Composite Caisson
We have developed a caisson composed of steel-concrete composite slabs and steel structures, which we call a `Hybrid Caisson.' We studied the structural principles and usability of the...
Development of Composite Slab with Truss-Typed Shear Connectors
This paper describes the results of the test on a steel-concrete composite slab with truss-typed shear connectors. This composite slab was recently developed. A series of tests were conducted...
Connection of Beam Flange to Concrete-Filled Tubular Column
Research has been carried out on a frame composed of a concrete-filled steel tubular column and H-shaped steel beam with the aim of developing a reasonable connection method. The proposed...
Thin Walled Circular Concrete Filled Steel Tubular Columns
The thin walled steel tube filled with high strength concrete delivers the economies of a concrete column with the speed of construction and the constructability of a steel column resulting...
Strength and Stiffness Behavior of Composite Steel Grid Decks
This paper briefly discusses the historical development of composite steel grid decks. The static and fatigue behavior under bending of filled and unfilled steel grid decks (exodermic)...
