ONE-PARAMETER MODELS FOR UNSATURATED HYDRAULIC CONDUCTIVITY

Soil Science, 1998
Simple one-parameter models for predicting changes in unsaturated soil hydraulic properties with changing soil-water content are useful, considering the great uncertainty and variability in the hydraulic parameters, and the models are often used for stochastic simulations of water and solute transport under field conditions.

ECONOMIC HYDRAULIC PARAMETERS FOR CONCRETING CANALS

Journal of Science and Innovative Development, 2020
Irrigation canals are of particular importance to provide water for irrigated areas. In recent years, the irrigation canals of Central Asia have been negatively affected by deformation phenomena. As a result, their hydraulic parameters changed and their throughput decreased. The results of the studies in the field of the deformations and designing open

Uncertainty of Hydraulic Parameters

Journal of Hydraulic Engineering, 1996
Reliability analysis and other probabilistic techniques are becoming increasingly important tools in hydraulic modeling and decision making. Probabilistic and reliability analyses are based on knowledge of the underlying parameter uncertainties. Hydraulic variables, such as roughness coefficient, channel slope, and critical shear stress, common to many

Parameter Estimation in Stochastic Hydraulic Models

IFAC Proceedings Volumes, 1989
Abstract In practice many large scale numerical models are used to simulate tidal motion in coastal waters, which is of great importance for flood forecasting in the Netherlands. One of the problems to be dealt with is the calibration of the models. A major part of it is the assignment of appropriate values to some uncertain parameters that occur in ...

Hydraulic parameter identification using aerial photographs

IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004
Some parameters embedded in open-channel flow equations lack definitive measurement methods. Optimal values of these parameters in a mathematical sense can be identified by using assimilation methods. New generations of satellites are now able to provide observation data that can be useful to implement inverse problems.

Parameter identifications of the hydraulic mount

International Technology and Innovation Conference 2009 (ITIC 2009), 2009
A lumped parameter model is proposed for analysis of dynamic behaviour of a Passive Hydraulic Engine Mount (PHEM) with incorporation of inertia track and throttle, which is characterized by effective and efficient vibration isolation behaviour in the range of both low and high frequencies.
