how to prevent surface runoff?

Steps
1
Minimize impervious surfaces on your property. In nature, most precipitation soaks into the ground where it falls. Plants absorb much of this through their roots, and some makes its way down to the water table, being purified as it gradually percolates through the soil.
2
Line impervious surfaces with gravel trenches. Figure out where water runs off your driveway or patio, and then dig a small trench along the edge. Fill it with gravel to slow the runoff and allow the water to seep into the soil.
3
Use the water that drains off your roof. A 1,000 square foot roof can produce more than 600 gallons (2,271.2 L) of runoff for every 1" of rain that falls on it. If your downspouts are connected directly to a storm drain, disconnecting them is the single most important step you can take to reduce runoff.
5
Add organic matter to your soil. Adding compost or mulch to your soil can make your plants happier, but it can also reduce runoff. Spread a 2-4" layer of organic material once a year.[5]
6
Don't leave soil exposed. Depending on your slope and soil type, bare soil can be nearly as impervious as concrete. If you can't or don't wish to plant vegetation on an exposed patch of soil, cover it with mulch, wood chips, or gravel. This is especially important for newly landscaped yards that don't yet have established vegetation.[6]
7
Plant trees and preserve existing ones. Trees' immense root systems effectively absorb water over a large area. In addition, the canopy of a tree slows the fall of rainwater so that the ground is capable of absorbing larger amounts than it otherwise would be.
