Description Usage Arguments Value Examples

Water level in a tank raises due to an inflow and lowers due to an outflow. An exessive inflow volume may result in water draining out the tank (lost_water variable in returned data.frame). The water tank needs a recharge whenever it does not guarantee the required outflow. The tank is recharged to its entire volume and is_recharged variable is set to TRUE.

1	get_tank_water_level(tank_level, water_in, water_out, tank_volume)

`tank_level`	level of water in the tank before in/out flows
`water_in`	the amount of water flowing in the tank (usually from rainfall), may be `NA`
`water_out`	the amount of water flowing out the tank (usually for lawn irrigation), may be `NA`
`tank_volume`	the total volume of the tank

a 1 row data.frame with the following variables: tank_level, water_in, is_recharged, lost_water

tank_level_l <- 2000
tank_vol_l <- 5000
# inflow = outflow, water level is unchanged
get_tank_water_level(tank_level_l,  500,  500, tank_vol_l)
# water level decreases
get_tank_water_level(tank_level_l,   NA, 1000, tank_vol_l)
# water level decreases, tank is recharged
get_tank_water_level(tank_level_l,    0, 2500, tank_vol_l)
# inflow fills up the tank, water is lost
get_tank_water_level(tank_level_l, 4000,  500, tank_vol_l)
