KSL

Parameter denoting simulation of landslide; if KSL=O,
no landslide, if KSL=l, a landslide occurring along
one bank of the reservoir is simulated; if KSL=2,
the landslide occurs along both banks of reservoir
landslide on opposite bank is mirror image of the
one that is specified on cards (55-56).

Note:. Card (16) is omitted if MUD=o (card (15)).

UW, VIS, SHR, PoWR - 4 F 10.0 Format

Unit weight (lb/ft3) of mud/debris fluid
Dynamic viscosity (lb' sec/ft2) of mUd/debri~ fluid
Initial yield stress or shear strength (lb/ft ) of
mud/debris fluid.
Exponent in power function representing the stress-
rate of strain relation, if Bingham plastic is
assumed for fluid, set PoWR = 1.0.

Omit card (17) if ITEH (card 2) is nonzero, If card (17) is i ncl uded,
then omit cards (18) and (19).

QO
RHO

Initial steady discharge (cfs),
Ratio of peak flow to initial flow of inflow
hydrograph for Gamma mathematical function to
create inflow hydrograph.
Ratio of time between toO and center of gravity of
inflow hydrograph to time between t=o and peak of
inflow hydrograph.
Time (hr) between toO and peak flow of inflow
hydrograph (hr).

GAMA

TPG

QI(K) - 8 F 10.0 Format

QI(K)

Inflow (cfs) at upstream end of reservoir or first
routing reach for each interval of time until time
TEH is reached; K goes from 1 to ITEH which can
assume a maximum value of 100; if ITEH=O, omit this
card.

Card (19) is omitted if DHF>O.o (card 15)),
