defineHeadBoundary: Helper function: define head boundary

In KWB-R/kwb.demeau: Heat tracer study SVH

Description

Helper function: define head boundary

Usage

defineHeadBoundary(head, nly, temp, ntx = 4, ntc = 1)

Arguments

head	as retrieved by convHeadBoundary()
nly	number of vertical nodes
temp	temperature at boundary
ntx	vector with node type identifier for boundary conditions. 0 (for no specified boundary (needed for resetting some nodes after initial recharge period); 1 (for specified pressure head); 2 (for specified flux per unit horizontal surface area in units of L/T); 3 (for possible seepage face); 4 (for specified total head); 5 (for evaporation, Note: is not implemented yet!); 6 (for specified volumetric flow in units of L3/T). 7 (for gravity drain). (The gravity drain boundary condition allows gravity driven vertical flow out of the domain assuming a unit vertical hydraulic gradient. Flow into the domain cannot occur.)"
ntc	vector with node type identifier for transport boundary conditions. 0 (for no specified boundary); 1 (for specified temperatures), (Default: 1)

Value

boundary head parameterisation
