Darcy Velocity
Calculates the
groundwater seepage velocity vector (direction and magnitude) for steady flow
in an aquifer.

Input groundwater head elevation raster أدخل البيانات النقطية لارتفاع رأس المياه الجوفية
The input raster where
each cell value represents the groundwater head elevation at that location.
The head is typically an
elevation above some datum, such as mean sea level.

ارتفاع رأس المياه الجوفية في ذلك الموقع.
عادةً ما يكون الرأس ارتفاعًا فوق بعض الإسناد ،
مثل متوسط مستوى سطح البحر.
Input effective formation porosity
raster
The input raster where each cell value represents the effective formation
porosity at that location.
Input saturated thickness raster
The input raster where each cell value represents the saturated thickness
at that location.
The value for the thickness is interpreted from geological properties of
the aquifer.
Input formation transmissivity
raster
The input raster where each cell value represents the formation
transmissivity at that location.
The transmissivity of an aquifer is defined as the hydraulic conductivity
K times the saturated aquifer thickness b, as units of length squared over
time. This property is generally estimated from field experimental data such as
pumping tests. Tables 1 and 2 in How Darcy Flow and Darcy Velocity work list
ranges of hydraulic conductivities for some generalized geologic materials.
Output direction raster
The output flow direction raster.
Each cell value represents the direction of the seepage velocity vector
(average linear velocity) at the center of the cell, calculated as the average
value of the seepage velocity through the four faces of the cell.
It is used with the output magnitude raster to describe the flow vector.
