Shall we always use hydraulic models? A graph neural network metamodel for water system calibration and uncertainty assessment.

Water Research, 2023
Representing reality in a numerical model is complex. Conventionally, hydraulic models of water distribution networks are a tool for replicating water supply system behaviour through simulation by means of approximation of physical equations.

Hydraulic model investigations. [PDF]

, 2020
This thesis is based upon the work and experience of the author since 1956. During this period he has been engaged in the design, construction and operation of hydraulic models, first as an engineer employed by the Department of Public Works, N.S.W. and then as a Lecturer in Civil Engineering in the University of Queensland.

Matching trends in channel width, sinuosity, and depth along the fluvial to marine transition zone of tide-dominated river deltas: The need for a revision of depositional and hydraulic models

Earth-Science Reviews, 2019
Along their fluvial to marine transition zone, tide-dominated river deltas show upstream to downstream trends in channel width, sinuosity, and depth, which at present have been only partially reported.

New Hydraulic System Modelling

Journal of Vibration and Control, 2004
The efficient design of hydraulic systems requires fast simulation methods. In most simulation programs, the hydraulic components are coupled by compressible joints. Since the compressibility of oil is very small, this leads to stiff differential equations.

Accurate Dynamic Modelling of Hydraulic Servomechanisms

2019 Design, Automation & Test in Europe Conference & Exhibition (DATE), 2019
In this paper, the process of modelling and identification of a hydraulic actuator is discussed. In this framework a simple model based on the classical theory has been derived and a first experimental campaign has been performed on a test bench. These tests highlighted the presence of unmodeled phenomena (e.g. dead-zone, hysteresis, etc.), therefore a

Assessing the effect of different bathymetric models on hydraulic simulation of rivers in data sparse regions

Journal of Hydrology, 2019
River bathymetry, which is vital for accurate hydraulic modeling, is not readily available at large scales because of the logistical difficulties in field surveys and uncertainties associated with remote sensing techniques.
