The design of your waterfall pond unit should blend seamlessly with rest of your landscape. According to Landscape Design Advice, if your outdoor space is formal, and has many linear features, like straight walls or rows of hedges, you will likely want to install a waterfall pond with a well-defined geometric shape.
This might be a square, rectangle, pentagon or hexagon. The waterfall in such a design should fall over a straight edge, to keep all of the elements linear.
Alternatively, if your outdoor space is void of strict linear elements, you may want to use a natural waterfall pond design. You can let the features of your landscape determine the shape of your pond, which could be long, narrow and curving, or wide and amorphous.
In such a landscape, you won't need a linear edge to tie elements together, so your waterfall can tumble over a group of rocks or another uneven, natural-looking structure.
There are a variety of materials you can use for your waterfall pond. If you have decided on a geometric design, using a pre-casted fiberglass or plastic waterfall pond unit is an easy-to-install and relatively inexpensive option, according to Peters Perfect Pond.
Alternatively, to create a uniquely shaped waterfall pond, that adheres to the curves of the natural landscape, you will likely want to use concrete or clay. However, this option is more expensive, and will likely require that you hire a professional to complete the installation.
When deciding on where you will place your waterfall pond, consider the slope, if there is one, of your outdoor space. One idea, perhaps best suited for a natural design, is to position your waterfall so that it is higher than your pond.
This will help make your waterfall seem less like a fountain running on an electric pump (which, it essentially is) and more like a natural waterfall that gravity is pulling on. According to Landscape Design Advice, another way to increase the natural-look is to position your waterfall pond far away your home and other manmade structures.
Alternatively, if you are using a formal design, try adjoining your unit to a patio, deck or garden. In either instance, if you plan on growing plants in your pond, make sure to put it in a spot where it can receive lots of sunlight.
