Peak flow control structures (leaky woody dams)

Submitted by Philippe Lanceleur on Sun, 09/22/2024 - 14:24

Peak flow control structures are designed to reduce flow velocities and quantities running down from catchment areas. Leaky dams are peak flow control structures that are made of wood and allow low flows to pass through, but hold back high flows, thus providing temporary storage and enhanced infiltration of flood water.

Maize strip tillage

Submitted by Philippe Lanceleur on Sun, 09/22/2024 - 14:24

A cropping system for maize which reduces the reworking of the soil to the stripes, in which the seeds are planted.

Small retention ponds in the forest

Submitted by Philippe Lanceleur on Sun, 09/22/2024 - 14:24

Small retention ponds, located in the forest, are ponds or pools with sufficient storage capacity to store the surface runoff to prevent flooding during heavy rainfall events. Ponds contain limited or no water during dry weather, but are designed to retain water during rain events.

Direct seeding

Submitted by Philippe Lanceleur on Sun, 09/22/2024 - 14:24

A cropping system which allows to plant the seeds directly into the soil without ploughing. The soil is covered with plant remainders.

Drainage Biofilter

Submitted by Philippe Lanceleur on Sun, 09/22/2024 - 14:24

Biofilters or “bioreactors” connected to agricultural tile drains are relatively inexpensive and space-saving measures with considerable potential to improve the quality of drainage water.

Small constructed wetland

Submitted by Philippe Lanceleur on Sun, 09/22/2024 - 14:24

A small constructed wetland is a combination of ponds and vegetation filters, designed mainly to remove sediment and nutrients from streams. It is usually located in first and second order streams in agricultural landscapes.

Grass buffer zones alongside waterways in cropland

Submitted by Philippe Lanceleur on Sun, 09/22/2024 - 14:24

Grass buffer zones are established along waterways in cropland to reduce the surface runoff rate, and the amounts of sediment, nutrients and pesticides in the runoff.

Afforestation of arable land

Submitted by Philippe Lanceleur on Sun, 09/22/2024 - 14:24

Afforestation is planting trees on previously non-forested land. Trees hold the soil and reduce runoff, and thus prevent erosion of the most fertile layers. It is an effective way to rehabilitate degraded lands, being a nature-based solution which addresses flood and soil erosion impacts.

Buffer strips and hedges around cropland

Submitted by Philippe Lanceleur on Sun, 09/22/2024 - 14:24

Buffer strips and hedges comprise natural vegetation of grass, bushes or trees. They are sited at the edges of fields, roads and surface water bodies. Their main function is to provide a natural buffer to control nutrient and sediment transport from agricultural fields by promoting water infiltration and slowing runoff, as well as preserving undisturbed green corridors.

Meadows and pastures

Submitted by Philippe Lanceleur on Sun, 09/22/2024 - 14:24

Permanent meadows or pastures are more effective in controlling land degradation than arable cropping. They are especially appropriate in hilly regions on sloping land where the risk of water erosion is high.
