Abstract:
The applicability of the stage-fall-discharge (SFD) method in combination with acoustic Doppler velocity meter (ADVM) data, upstream of a hydraulic structure, specifically, the Sejong-weir located in the Geum River, Korea, was examined. We developed three rating curves: a conventional simple rating curve with the data measured using an acoustic Doppler current profiler (ADCP) and floating objects, an SFD rating curve with the data measured using the ADCP and floating objects, and an SFD rating curve with the data measured using an ADVM. Because of the gate operation effect, every rating curve

Abstract. Hydrological models play an important role in water resources management. These models generally rely on discharge data for calibration. Discharge time series are normally derived from observed water levels by using a rating curve. However, this method suffers from many uncertainties due to insufficient observations, inadequate rating curve fitting procedures, rating curve extrapolation, and temporal changes in the river geometry. Unfortunately, this problem is prominent in many African river basins. In this study, an alternative calibration method is presented using water-level time

One of the fundamental issues with the operation of surface water resources is erosion, and sediment transport. Reducing the reservoir’s useful life and declining the reservoir storage are subsequences of erosion and sediment transport. These natural events occur in different geographical circumstances. Since the major part of the watershed sedimentation consists of suspended sediments, the amount of suspended loads, has a special priority.

Abstract:
The heat removal efficiency of a storage tank is effective to evaluate the thermal energy that users can obtain during its heat removal phase. With different types and volumes Vt, from 174 L to 1093 L, of six vertical mantle storage tanks widely applied to heat pumps and solar heating systems, the analyses of heat removal patterns were carried out. In addition, using a new integrated variable (Ti − Tw)/ V˙d found from the heat removal patterns, an empirical model of heat removal efficiency has been developed. The study found that the empirical model is a logarithmic curve ηR = aLn((Ti − Tw)/V˙

Abstract:
In ductile materials the fracture toughness is usually characterised by a tearing resistance curve, or R-curve, plotting the fracture toughness in terms of J or CTOD against crack extension. Recent research has evaluated the methods to determine CTOD in engineering alloys with a wide range of yield to tensile (Y/T) ratios for single point CTOD. This work develops the investigation into R-curves, and reviews the assumptions about SENB specimens deforming under rigid rotation, the evaluation of CTOD from J for R-curves, and the nature of tearing initiation in low Y/T ratio stainless steel, from

The stack line is vertically symmetrical, composed of two third-order Bezier curves and a straight line.

Abstract:
In order to obtain the fracture toughness curve of inhomogeneous CT specimens, a simplified J-R curve estimation method has been proposed. To verify the applicability of this method, the fracture toughness test and the finite element analysis has been conducted. In overmatching case (mismatch ratio M = 2.2), the conventional ASTM standard’s J-R curve exceeded the J-R curve from the FE analysis in the plane strain condition by over 20%. On the other hand, the simplified J-R curve was located between J-R curves from the FE analyses in plane strain and plane stress condition. In undermatching cas

For all the materials studied, a transition load ratio Rt was found, which marks the transition between a dominant influence of ΔK or Kmax on FCGR behavior. F

Numerous tests have been performed in the nuclear industry to determine damping ratios for the analysis of steam generator tube bundles. Several methods have been used to analyze the response data, including the logarithmic decrement method, the half-power point method, and curve-fitting methods. Theoretically, the methods give the same damping results; however, in practice, the results may be appreciably different. Each of these methods presents certain difficulties in determining a damping ratio. For the half-power point method, the difficulties include selecting a sampling rate, setting a t

Abstract:
Buried pipelines subjected to non-continuous ground movement such as frost heave, thaw settlement, slope instability and seismic movement experience high compressive strains that can cause local buckling (or wrinkling), in which the pipe wall buckles like a thin cylindrical shell in axial compression. In a strain-based design and assessment framework, excessive local buckling deformation that may cause loss of serviceability, or even pressure containment in some cases, is managed by limiting the strain demand below the strain limit. The determination of compressive strain limit is typically pe
