Russian term
гидродинамическое взвешивание
Russian to English
Tech/Engineering
Construction / Civil Engineering
грунтовые сооружения
Опасные нарушения грунтов могут возникнуть также при открытом водоотливе. К ним относятся вынос мелких частиц на откосах, а также вспучивание дна котлована вследствие гидродинамического взвешивания.

hydrostatic loading
I believe that the author had in mind hydrostatic, not hydrodynamic, although one Russian article speaks of hydrodynamic weighing, which does not find confirmation in English literature.
I believe in the context of trench/excavation stability, the issue is hydrostatic loading - the constant pressure of groundwater on the sides of the excavation

Hydrostatics is the study of fluids at rest, and the study of the forces that can be exerted by those fluids. If you put a fluid under pressure, it can exert a force.
Hydrodynamics is the study of fluids in motion. It is about when we use that motion to do useful work - for example, a fluid flywheel. When fluid flows, that flow may be smooth and steady (laminar flow) or unsettled and disturbed (turbulent flow)

5.48. Dangerous soil damage can also occur with open drainage. These include the removal of small particles on the slopes, as well as the expansion of the bottom of the pit due to hydrodynamic weighing.

Water/cement ratio = 0.45 maximum (all concrete exposed to hydrostatic loading), 0.50 maximum (all other concrete)

Design shall address hydrostatic loading, seismic loading, rapid drawdown, surcharge, velocity effects, and back slopes where appropriate.

The interior surfacing system shall be continuously bonded to all brick, mortar, concrete, chemical sealant, grout, pipe and other surfaces inside the manhole according to ASTM C882 testing and therefore shall be designed for hydrostatic loading

Dewatering was carried out with an external
ring of wellpoints (see figure). The external drawdown removed the hydrostatic loading on the sheet-piles, avoiding
the need for other support.
. External wells have the advantage of being out of the
way of the excavation and can reduce the hydrostatic loading on the retaining walls with potential for a saving in propping or anchoring requirements. I

Фильтрационный поток, формирующийся в направлении к месту отбора воды (к скважинам, дренажу или к горной выработке), создает гидродинамическое давление на грунт, ослабляет прочностные связи в нем и может вызвать вынос частиц грунта. Понижение уровня воды вызывает уменьшение взвешивающего давления в грунте и, как следствие, дополнительные его осадки.

Reference is to loss of fine particles on slopes and to upheaval of pit bottom due to hydrodynamic suspension/buoyancy, not erroneously hydrostatic since with upheaval/uplift the pressure changes. ..взвешивание is used for fluidization in metallurgy, not here, as far as I know. In IrinaN's reply's citation, уменьшение взвешивающего давления simply means decrease of uplift
