Prediction of Occurrence and Runoff Analysis of Debris Flow
A debris flow will occur on a slope when the rainfall exceeds a certain value determined by the hydraulic, geological and topographic properties of the slope. To estimate this critical...
The Concept of Local Euler Number as an Aid for Sizing Pitot Tubes
Correlations with drag coefficients enable determining the relations between the form of Pitot tubes and their velocity coefficients. A numerical example is presented to clear the use...
Design of a Curved Baffle Energy Dissipation Structure
A curved baffle energy dissipation structure was designed and constructed based on the results of hydraulic and analytical models. Field tests of the prototype demonstrate close comparison...
Hydrologic Design: Extending Traditional Methods
A review of traditional hydrologic design shows that it is inadequate. The continued adaptation of manual techniques into computer software without a major change in fundamental assumptions...
Progressive Failure of an Overtopped Embankment
The failure of an overtopped embankment is a problem of a very complicated nature. Concerned organizations are interested in information that can be used in future planning and development...
A New Type of Concrete Trapezoid Dam
A new type of 128.0 m height concrete trapezoid dam (t-d) has been built for the Wunana Town Hydroelectric Power Station (WTHPS). The paper presents its optimum section design, several...
Galveston Bay 3-D Model Study Channel Deepening Lessons Learned in Management of a Large Modeling Study
The numerical modeling of Galveston Bay in 3-D for long time durations with many geometry and hydrologic scenarios, coupled with the need to store all data for subsequent use in a model...
Reference Surfaces for Bridge Scour Depths
Depth of scour is measured as the vertical distance between scoured channel geometry and a measurement reference surface. A scour depth measurement can have a wide range depending on the...
Probability of Bridge Failure Due to Scouring
Models to estimate depth of scour at bridge piers and abutments are available in many forms,but all of them are based on constant discharges. Their results vary widely and engineering...
Uncertainty of Bridge Scour Estimates
Pier scour is the erosion of a streambed in the vicinity of bridge pier foundations. In this paper, fuzzy regression is used to develop two pier scour models, one based on crisp laboratory...
Uncertainty Analysis of the FEMA Method for Alluvial Fans
Distributary flow areas such as alluvial fans, bajadas, and alluvial slopes, and alluvial plains along mountain bases pose quite different and interesting problems for the design of hydraulic...
Three-Dimensional Modeling of the Coastal Region Offshore from Sydney, Australia
Care must be taken in model formulation to ensure that unwanted internal circulation cannot be induced. Extensive model testing must be carried out on possible distorted element shapes...
New York Bight Three-Dimensional Water Quality Model
The numerical modeling technology developed for Chesapeake Bay was applied to the Middle Atlantic Bight extending 550 km form Cape May, NJ, northeasterly to Nantucket Island, MA, and extending...
Serviceability Stress Limits for Composite Beams
Serviceability limits are increasingly becoming the critical design requirement for composite beams. A set of three illustrative design studies indicates that this is particularly true...
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 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...
Cyclic Lateral Load Analysis of Composite Frames
A method of analysis for composite building frames subjected to repeated and reversed lateral loads has been developed as part of an overall investigation of seismic response of composite...
Semi-Rigid Joint Action in Composite Frames: Numerical Analysis and Design Criteria
The paper focusses on the analysis of semi-rigid composite frames, reporting mainly on the results of a research study which combines the experimental and theoretical approaches. Attention...
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...
Composite Columns Subjected to Bending and Shear
This paper describes experimental as well as analytical studies of the post elastic deformation and fracture behaviors of wide flange steel encased reinforced concrete (SRC) composite...
