III.3.4 - Dam Parameters

Table 16 Dam-related tokens
Token	Definition
dam	Names the dam. The name must be present in the columbia.desc file, and must be paired with an end statement.
pred_den_forebay	Describes the density of predators in the forebay.
pred_den_tailrace	Describes the total predator population in the tailrace.
tailrace_length	Length of the tailrace in feet.
mod_*	Parameters used in modulation of flows.
mod_ou_r	Specifies correlation of flow from one day to the next.
mod_ou_sigma	Standard deviation to use when modulating flows at farthest upstream dams.
mod_norm_sigma	Standard deviation to use when modulating flows at downstream dams.
mod_weekly_amp	Amplitude of weekly variation imposed on modulation.
nsat_equation	Equation describing the ability of the dam to generate gas saturation as a function of the amount of water spilled over the dam. The number following the token dictates the form of the equation used. Three parameters are used. This must be paired with an end statement.
spill_mort	species-specific value for mortality suffered as fish pass through the spillway. This is a stochastic parameter.
bypass_mort	species-specific value for mortality suffered in the bypass system. This is a stochastic parameter.
turbine_mort	species-specific value for mortality suffered during turbine passage. This is a stochastic parameter.
transport_mort	species-specific value for mortality suffered during the entire transport process. This is a stochastic parameter.
separation_prob	species-specific parameter for ability to separate individuals of that species during bypass, in percentage.
predation_prob	species-specific array of values describing the relative success of predators during each 2-hour segment of the day; generally this is 1 for all periods.
day_fge	species-specific parameter describing fge during daylight hours. This is a stochastic parameter.
night_fge	species-specific parameter describing fge during nighttime hours. This is a stochastic parameter.
spill_cap	maximum allowable flow that is allowed to pass through spill.
spill_equation	equation describing the spill efficiency at the dam. The number following the token dictates the functional form of the equation; usually linear. Three parameters.
powerhouse_ schedule	Array of hours during which a powerhouse may operate. This generally defaults to 24 hours year round.
powerhouse_ priority	Dictates whether the powerhouse is the primary or secondary powerhouse.
powerhouse_ threshold	Amount of spill allowed over primary powerhouse capacity before secondary powerhouse is turned on.
additional_ powerhouse	names a second powerhouse if one exists at the project. This powerhouse has separate specifications for priority, schedule, threshold, passage mortalities, and fge. It must have a closing end statement.
fish_spill	days and hours of the day during which planned spill is allocated.
planned_spill	periods of one or many days and an associated amount of spill as a fraction of total flow. There may be many periods.
flow_min	Minimum flow allowed at a dam, in kcfs.
