Weather for the Water Module is defined as a Weather data. defines a number of environmental circumstances the hydrological model is subject to. It also defines the (total) simulation time.

Weather is a required connection. There is always exactly one weather connected to a water overlay, and by default if no weather exists an appropriate weather effect is created and connected automatically.

Rain is a consistent addition of water to the hydrological model over a specified period of time. At the end of the rainfall's duration, the specified amount of rain will have fallen in each location in the project. The simulation can calculate both periods of rain as well as dry periods by setting the amount of rain for a specific period to 0. During any period, the amount of water added by rain per timestep is constant.

Evaporation is the consistent removal of water from the hydrological model over a specified period of time. As long as evaporation takes places at a certain rate, water both on the surface and underground can be subject to removal from the hydrological model. The evaporation rate defined by the weather is the base amount of all types of evaporation in the calculation.

The simulation time is equal to the total amount of time defined for rainfall (and the accompanying dry periods).

Attribute Unit Description
RAIN_M end-time, m An array of values, each pair indicating until what time that period of rain will last and how much rain will fall in that period.
EVAPORATION_M end time, m/day An array of values, each pair indicating until what time that period of evaporation will last and what the evaporation rate is in that period.
