This paper critically compares the use of laboratory tests against in situ combined with numerical seepage modeling to determine hydraulic conductivity natural soil deposits. Laboratory determination used constant head permeability and oedometer on undisturbed Shelby tube block samples. The auger hole method Guelph permeameter were performed field. Groundwater table elevations deposits differen...

This study developed an original constant-head permeability apparatus for rocks. can freely adjust the confining pressure and hydraulic (hydraulic gradient), directly measure runoff volume using electronic balance. conductivity more accurately than conventional method that measures a measuring cylinder. Second, this measured of Inada granite specimens (50 mm in diameter 40 length) under conditi...

The paper takes Jinping II Hydropower Station (8 × 600MW) as an example based on the internal mechanism and operating characteristics of system, complete simulation model super-long large water diversion power generation system has been completed finally.Besides, method parameter calibration correction for main elements is proposed.By model, two typical hydraulic transient process test conditio...

Hydraulic structures are man-made waterworks interacting with the rainfall run-off to store and convey water, or mitigate impact of run-off. Current approaches in hydraulic structure design tend be conservative, not much differing from ancient designs. Modern often designed based upon simplistic concepts optimize their performances. However, today’s engineers must embrace a number new challenge...

Hydraulic systems may involve both pipelines and open channels, which challenges the hydraulic transient analysis. In this paper, a method of characteristics (MOC)-finite volume (FVM) coupling has been developed with pipeline modelled using MOC channel FVM. The boundaries between these two simulation regions are based on Riemann invariants. simulated parameters can be transmitted from region to...

INTRODUCTION: The calculation of Manning n values has been of interest since the Manning equation was presented in the late 1800s (Henderson, 1966). While estimation of n vahm for normal channels has been fairly well standardized, the estimation of n values in areas of dense vegetation continues to be subject to large variations depending on the experience of the engineer and the perceived dens...

Abstract Despite significant advancements in geomodelling technologies, Accurately estimating hydraulic fracture half-length remains a challenging task. This paper introduces detailed estimation approach using the Gaussian Pressure Transient (GPT) method, which is relatively new. The GPT method iterative, ensuring fast convergence and providing reliable estimations of b’ased on predetermined di...

A collaboration between the University of Florida and the Swiss Federal Institute of Technology, Lausanne (EPFL) has been formed to develop and validate detailed coupled multiphysics models of the zero-power (100 W) CROCUS reactor at EPFL and the 100 kW University of Florida Training Reactor, for the comprehensive analysis of the reactor behavior under transient (neutronic or thermal-hydraulic ...
