'I've taken up a fair amount of my column space in WaterShapes with discussions of the wise use of water, and for good reason: What could be more important to watershapers,' wrote Bruce Zaretsky to open the April 2010 edition of On the Level, 'than knowing how to make the best possible use of the material that defines our profession? 'The common thread in all of this coverage . . . is that, ultimately, our aim must be to preserve the integrity of water, to cleanse it for return to the groundwater system and to
I’ve taken up a fair amount of my column space in WaterShapes with discussions of the wise use of water, and for good reason: What could be more important to watershapers than knowing how to make the best possible use of the material that defines our profession? And what could be better than the fact that it’s possible to approach the subject in positive ways that bode well for the future? The common thread in all of this coverage – whether it’s about conservation, constructed wetlands or rainwater harvesting – is that, ultimately, our aim must be to
A rainstorm is a good thing: It gives us water, fills our lakes and streams, feeds our crops and landscapes and arguably makes our way of life possible. But if there's too much of that good thing, it can also irreparably damage homes, roadways, curb and gutter, crops, landscapes and other elements of the environment, particularly when we've altered the topography to suit our own purposes. The importance of erosion control and the need for including it in any land-altering project has been underscored through the years by numerous disasters, including landslides that have resulted in property destruction and even
Think about what happens when rainwater falls on an impervious surface in a big outdoor parking lot studded by the occasional tree: The water dampens the surface, which instantly becomes saturated. Only a minute percentage of water that penetrates the trees' canopies to reach their curb-bound planters becomes available to the trees' roots. The rest almost immediately starts flowing to drain grates or perimeter drainage details and is lost to a stormwater-collection system. The trees are helped only marginally by the life-giving rain, and the water
Throughout recorded history, people have tried to control the elements in every which way they can. We plant trees to block the wind, build levees to hold back rising river water and dikes to hold back the seas. We build skyscrapers that defy gravity, winds and earthquakes. For all of this ingenuity, however, we sometimes don't do a very good job. When our efforts to control the elements fail on a large scale, we witness catastrophes that
