If you want to integrate a stream into your garden, you should let it flow down a slight slope - and also invest in a sensible pump. So that the brook does not mutate into a trickle or even into a torrent, the pumping capacity and thus the required amount of water should be adapted to the circumstances.
The amount of water is important for the right pump
Rule of thumb for the right pump
There is a simple rule of thumb for calculating the required amount of water and thus the pumping capacity for a stream:
The width of the creek x 1.5 equals the amount pumped per minute
A stream that is 40 centimeters wide therefore requires a pump that delivers 60 liters of water per minute. The water reservoir or the garden pond, on the other hand, should be able to hold about a third of this amount of water - calculated per hour. With around 3600 liters per hour, the pond should therefore have a capacity of at least 1200 liters.
tips
If your stream is unevenly wide, use the average value for the calculation.
