The watercourse is not an overly complicated structure. A slight tilt is all it takes to set the water in motion.It is assumed that the desired effect is given by a slope of the terrain of 2-3 centimeters per linear meter of the ground.The water then runs very smoothly and makes a soft rumble. To create an imitation of a mountain stream, the terrain must have a much greater slope.
Then the water will run off faster, boil over the cascades and emit a characteristic splash.On flat terrain, the soil chosen for the construction of the pond (or pond) can be used to model the watercourse bed.Each water design, including the watercourse, has its own style.
Of course, the more it corresponds with the environment, the better. It is assumed that the optimal bed length for a watercourse with different arrangements (with cascades, terraces and arches) should be at least 4 meters.On such a surface, the stream can be additionally equipped with bends and plant niches with hollows that keep the water even when the pump is turned off.Soil modeling should be started at the stage of extracting the soil, the last grinding is made of the trough when making sand bedding and laying foil lining.
Foil is the most commonly used sealing material. Long, narrow tapes from a roll are the best, they can be the same materials that were used to seal the eyelet. The foils can be made of PVC, PE or rubber, their width may vary from several dozen centimeters to even several meters. A special type of substrate are the so-called gravel foil (lined with fine gravel), perfectly imitating a rocky bottom.When laying the foil, the same rules apply as for sealing the mesh.
You have to take care of, among others that the edge of the foil is folded over the edge of the pond (so that the water from the stream does not seep into the ground). When the stream runs through streamers, the bottom should be sealed with several sheets laid with overlaps and joined with a special glue or adhesive tape.
Foil is the most popular material, but not the only one. Rarer, but not without advantages, are ready-made plastic modules. Some manufacturers cover them with a layer of natural sandstone.These are durable and easy-to-stack elements, but non-plastic, and therefore allow you to build assumptions with a rather cliché-like appearance.Remember that the molds are folded from the bottom to the top.

Water in the watercourse circulates in a closed circuit. It begins in a spring or a fountain, and it opens out in a pond or a well, from where it is pumped to the spring. The pumps have different capacities, from less than 2 to more than 20,000 liters per hour.
Efficiency must always be well matched to the length and inclination of the watercourse, otherwise the stream will be either too weak or too rapid. of a stream with a moderate slope, a pump with a capacity of 10,000 liters of water per hour will be good.
Foiled streams have the advantage over modular ones that they are easier to arrange with both aquatic and bedding plants. The foil is easy to disguise with stones (ordinary fieldstones are perfect for this) and creeping perennials, e.g. algae and geraniums.Outside the water zone, you can plant tawulas and loosestrife.
