Functions
double	SH1 (double t, double x4)
double	SH2 (double t, double x4)
void	ComputeOrdinates (double x4, std::vector< double > &uh1Ord, std::vector< double > &uh2Ord)

Detailed Description

Shared GR unit-hydrograph S-curves and ordinate computation (Perrin et al., 2003).

Used by the GR6J routing process. GR4J keeps its own equivalent copy embedded in ProcessRoutingGR4J so that class stays untouched.

Function Documentation

ComputeOrdinates()

void gr_uh::ComputeOrdinates ( double x4, std::vector< double > & uh1Ord, std::vector< double > & uh2Ord )

inline

Fill the UH1 and UH2 ordinates (successive differences of the S-curves) for the given time base x4 (clamped to a minimum of 0.5). The ordinate vectors are resized to ceil(x4) and ceil(2*x4) respectively.

Parameters

x4	unit-hydrograph time base [d].
uh1Ord	output UH1 ordinates.
uh2Ord	output UH2 ordinates.

SH1()

double gr_uh::SH1 ( double t, double x4 )

inline

SH1 cumulative S-curve, time base x4.

SH2()

double gr_uh::SH2 ( double t, double x4 )

inline

SH2 cumulative S-curve, time base 2*x4.
