evaporation
In recent years, I've had the good fortune to tackle a number of watershaping projects in the islands off the coast of eastern North America. From the West Indies to the Caribbean, I've learned in pursuing these projects that fresh water and electricity can be amazingly expensive commodities. These are, of course, settings in which numerous clients want to take advantage of water-on-water views. Trouble is, the vanishing edges that achieve these effects are questionable choices where the energy required to run them is costly; where winds and evaporation

When agitated or flowing water moves through the air, it loses carbon dioxide. That's particularly significant in systems with fountain jets, waterfalls or vanishing edges, observes Kim Skinner, with the loss affecting pH in ways that must be dealt with to avoid big problems.
In my work as a construction-defect expert witness, I see a certain problem in the design and construction of spillways all too frequently: When the system is initiated, the flow of water down the face of the dam wall will behave more or less as desired, holding to a narrow path into the pool or trough that awaits it. After a time, however, that water will begin to migrate, spreading out farther and farther beyond the desired pathway until the material - usually some sort of
