Abstract

The use of monolayers to reduce evaporation was originally developed in 1925 (Frenkiel 1965). The major problem with using monolayers is the difficulty associated with the
prediction and control of the distribution of the monolayer to the water surface. Full scale experiments are not very successful due to difficulties quantitatively measuring the
evaporation resistance the monolayer provides to different areas of the water surface.

A simulation of the monolayer as it disperses and degrades on the water surface can be used to predict the long term performance as well as a real time control system. The
model was created in MATLAB and simulates the behaviour of the monolayer based on experimental results. The simulation selects the optimal application rate for each individual applicator based on maximising the amount of money saved by comparing the money gained from all possible permutations of applicator rates and applicator positions. The money saved has two parts, the cost associated with distributing the monolayer and the value of the water saved from evaporation. This comparison is performed for each small time step. After the optimal permutation of rates has been
found, the optimal permutation of rates for the following time step is calculated
