Detailed Description
Ponds are defined as freshwater bodies between 25m2 and 5000m2. For newts the effective size is limited to 400m2.
Currently the only pond 'behviour' is related to provision of food for newt larvae. This is determined daily and can be seasonally adjusted.

Member Function Documentation
◆ CalcLarvalFood()
| void Pond::CalcLarvalFood | ( | ) |
Calculates the amount of larval food present
The larval food is calculated assuming a logistic equation in the form of Nt+1 = Nt+(N*r * (1-N/K)) t = one day, N is a scaler which is multiplied by a constant and the area of the pond to get the total larval food, K & r are carrying capacity and instantaneous reproductive rate respectively. K can change with season and this is currently hard coded, but could be an input variable later. The values are held in LarvalFoodMonthlyK
The steps in the calculation are:
- Enforce a assumed pond size for newts as maximum 400 m2
- Ensure we never get zero larval food, so there is always something to grow the curve from.
- Back calculate the current scaler value. This is needed because between time steps, food may be eaten by larvae. This is done based on the area and a fixed constant held in cfg_PondLarvalFoodBiomassConst
- Calculate the new scaler based on the logistic equation as described above
- Re-calculate the new total food biomass based on the area and a fixed constant held in cfg_PondLarvalFoodBiomassConst

◆ CalcPondPesticide()
| void Pond::CalcPondPesticide | ( | ) |
Calculates the amount of pesticide per unit pond water
The pesticide is calculated based on the mean concentration per m2 which is then multiplied by a factor representing run-off from the surroundings or other movements of pesticides through soil into the pond. This method assumes a uniform depth of water, which is then ignored (so can be seen as being part of the run-off factor). The pesticide concentration is calculated each day. These calculations are heavy on CPU time because of the need to search the landscape map for pond 1m2 and sum pesticide. So this has to be set to run by flagging using cfg_calc_pond_pesticide
To create the sum of pesticide the map is searched from min x,y to max x,y coords, and pond cells are summed for their pesticide content. Then the mean found.
We assume a mean pond depth of 1 m, so pesticide per l = m_pondpesticide/1000 to get per litre then multiplied buy the run-off factor

◆ SubtractLarvalFood()
| bool Pond::SubtractLarvalFood | ( | double | a_food | ) |
Called by a larva when feeding, removes an age specific amount of larval food
If the total amount of food is low then there is a probability test to determine if food can be found. If failed the return code false means no food was removed. If passed then this removes the amount of food passed in a_food and return true.
