Results

A series of results from the model.

Rainfall

A comparison of average results of simulation run with varying levels of rainfall, with all other parameters set to default values:

Rainfall
Scenario % Loss of Land (tiles) % Loss of Parciantes % Loss of Acequias
Default - 15 1.1 20.0 59.9
Drought - 1 10.5 19.9 59.9
Flood - 50 0.2 6.4 57.6

Real Estate Agents

A comparison of average results of simulation run with varying numbers of Real Estate agents, with all other parameters set to default values:

Real Estate Agents
Scenario % Loss of Land (tiles) % Loss of Parciantes % Loss of Acequias
Default - 10 1.1 20.0 59.9
0 Realtors 0.0 0.0 56.3
100 Realtors 5.6 99.9 99.9

Costs versus Culture

A comparison of the results of the nine scenarios with varying acequia maintenance costs and Parciante attitude distributions. The "Traditionalist" strategy profile entails that 80% of the Parciantes were Traditionalists, 10% were Followers, and 10% were Prodigals. Likewise the "Followers" strategy profile has 80% of its Parciantes as Followers, and so forth.

Maintenance Costs versus Cultural Valuation
Cost = 1
Scenario % Loss of Land (tiles) % Loss of Parciantes % Loss of Acequias

Followers 0.9 14.0 59.0
Prodigals 0.9 13.8 58.9
Cost = 5
