daily_cost {FlowRegEnvCost}

Calculates the daily environmental costs of flow regulation

Description

Calculates the daily environmental costs of flow regulation

Usage

daily_cost(First_year, Last_year, Year_evaluated, Year_impact, a_low, a_high,
  b_low, b_high)

Arguments

First_year

First year to consider in the analysis starting on October 1st (e.g.: First_year = 1964)

Last_year

First year to consider in the analysis finishing on September 30th (e.g.: Last_year = 2011)

Year_evaluated

Year when the environmental impact is evaluated (e.g.: Year_evaluated = 2010)

Year_impact

Year when the human impact started (the construction of a dam) (e.g.: Year_impact = 1988)

a_low

Coefficient a of Low-flow impact of function ku (e.g.: a_low = 0.05)

a_high

Coefficient a of High-flow impact of function ku (e.g.: a_high = 0.01)

b_low

Coefficient b of Low-flow impact of function ku (e.g.: b_low = 2)

b_high

Coefficient b of High-flow impact of function ku (e.g.: b_high = 2)

Value

Calculates the daily environmental costs of flow regulation for a specific year evaluated.
