Horizontal Pressure Gradient Parameterization for One‐Dimensional Lake Models [PDF]

Journal of Advances in Modeling Earth Systems, 2020
This work presents a new method for closure of horizontally averaged 1‐D thermohydrodynamic equations in an enclosed reservoir by parameterizing the horizontal pressure gradient usually omitted in 1‐D lake models. Horizontal pressure gradient is computed

Fortnightly variability of horizontal salinity gradient affects exchange flow in the Sumjin River estuary

Frontiers in Marine Science, 2022
The horizontal salinity gradient has been reported to play a crucial role in fortnightly variability of estuarine exchange flow in short estuaries. However, spatiotemporal variations in the salinity gradient and exchange flow have not been examined over ...

Experimental Study on Horizontal Resistance Parameter of Gravelly Soil Considering Slope Gradient Factor

Buildings
Horizontal resistance can be significantly different for gravelly soil slope sites with different gradients. The impact of slope gradient on the horizontal resistance of soil based on a three-dimensional physical simulation test has been investigated ...

Comparison of different approaches of computing the tilt angle of the total horizontal gradient and tilt angle of the analytic signal amplitude for detecting source edges

Bulletin of the Mineral Research and Exploration, 2021
This paper compares effectiveness of the different approaches of computing the tilt angle of the horizontal gradient amplitude and tilt angle of the analytic signal amplitude such as use of direct expression and frequency domain technique (also called k -

APPLICATION OF GENERALIZED DERIVATIVE OPERATOR ON BOUGUER ANOMALY FOR DETECTING GEOLOGICAL STRUCTURES

JGE, 2022
Generalized Derivative Operator (GDO) is one of the first-order derivative filters that could control the derivative’s direction by modifying the value of azimuth () and dip () parameters.

Gradient horizontal de fonctions polynomiales [PDF]

Annales de l'Institut Fourier, 2009
Nous étudions les trajectoires du gradient sous-riemannien (appellé horizontal) de fonctions polynômes. Dans ce cadre l’inégalité de Łojasiewicz n’est pas valide et une trajectoire du gradient horizontal peut être de longueur infinie, et peut même s’accumuler sur une courbe fermée.

Ocean dynamic equations with the real gravity

Scientific Reports, 2021
Two different treatments in ocean dynamics are found between the gravity and pressure gradient force. Vertical component is 5–6 orders of magnitude larger than horizontal components for the pressure gradient force in large-scale motion, and for the ...
