Key finding (our summary)
Combined modelling and experiments showing white-ball covers consistently outperform black and mixed-colour covers. Low surface-flow rates (below an optimal threshold) enhanced suppression by cooling the water surface, whereas flow rates above the threshold increased evaporative loss — a nuance relevant to reservoirs with inflow/outflow circulation.
Adds a flow-rate twist to the cover story: gentle circulation can help, but too much undoes the benefit.
