1 hr confidence: (hydraulic) gradient / slope of the water table
Explanation:
...this is definitely NOT a mere level difference; it is measured in m/km.
Verhang
Het verhang is het relatieve hoogteverschil van een watergang, uitgedrukt in m/km (meters per kilometer). Zo is het (gemiddelde) verhang van de beek de Geul 4,3 m/km, zijnde 250 m (het totale hoogteverschil) : 58 km (de totale lengte).

Ref. 1
Discharge and Velocity
The rate at which groundwater moves through the saturated zone depends on the permeability of the rock and the hydraulic gradient. The hydraulic gradient is defined as the difference in elevation divided by the distance between two points on the water table.
Ref. 2
Groundwater movement is dependent on the degree of interconnection of the porous space
(permeability) and the gradient or slope of the water table. These factors vary greatly depending
on the aquifer type. Groundwater in a carbonate aquifer can occasionally move through limestone
caverns as rapidly as surface water (1-3 ft/sec). In sandy aquifers, groundwater can move as
slowly as 3 ft/day or even as slowly as 1 in/day. For those reasons, groundwater cleanup, or
remediation, can only be done by enhanced methods.* These methods are complex and
expensive, making groundwater pollution prevention quite economical. There are obvious health
protection reasons for groundwater pollution prevention, as well.
