func (*TEM) ConcentrationTime

func (t *TEM) ConcentrationTime() map[int]int

func (*TEM) ContributingAreaIDs

func (t *TEM) ContributingAreaIDs(cid0 int) []int

ContributingAreaIDs returns a list of upslope cell IDs that make up the contributing area to cid0

func (*TEM) ContributingCellCounts

func (t *TEM) ContributingCellCounts() map[int]int

ContributingCellCounts returns a map of upslope TEC count for every TEC in TEM

func (*TEM) ContributingCellMap

func (t *TEM) ContributingCellMap(cid0 int) map[int]int

ContributingCellMap returns a map of upslope TEC count for every TEC in TEM cascading to cellID cid0.

func (*TEM) DownslopeContributingAreaIDs

func (t *TEM) DownslopeContributingAreaIDs(cid0 int) ([]int, map[int]int)
