Vegetative Filter Strips Reduce Runoff Losses and Help Protect Water Quality
Potential contamination (pollution) of surface waters with sediment, nutrients, and pesticides in agricultural runoff is an important water quality issue. Conservation tillage has been promoted and adopted by many row crop farmers because of its effectiveness in decreasing exposure to rainfall and reducing runoff and sediment loss. Vegetative filter strips (VFS), also known as buffer strips or ...
متن کاملLITERATURE REVIEW ON BUFFER POLLUTANT REMOVAL March 29 , 2010
A riparian buffer (also known as riparian vegetative filter strips, or buffer strips) is an area of vegetated land surrounding a waterbody, potentially capable of filtering non-point source pollution in runoff from adjacent lands. Main pollutants studied include sediment, nitrogen, phosphorus, bacteria, and pesticides. Although the literature suggests a general consensus about a riparian buffer...
متن کاملA design aid for sizing filter strips using buffer area ratio
Nonuniform field runoff can reduce the effectiveness of filter strips that are a uniform size along a field margin. Effectiveness can be improved by placing more filter strip where the runoff load is greater and less where the load is smaller. A modeling analysis was conducted of the relationship between pollutant trapping efficiency and the ratio of filter strip area to upslope contributing ar...

The performance of vegetative filter strips is governed by complex mechanisms. Models can help simulate the field conditions and predict the buffer effectiveness. A single event model for simulating the hydrology and sediment filtration in buffer strips is developed and field tested. Input parameters, sensitivity analysis, calibration and field testing of the model are presented. The model was ...
متن کاملEffectiveness of variable-width buffer design for sediment reduction
Vegetative buffer strips are vegetated areas (usually strips) between fields and waterbodies that can mitigate the effects of agricultural activities by acting as a physical barrier to sediment and nutrients being carried to streams, and thereby have been widely used as a best management practice (BMP). Buffers can slow surface water flow and allow greater water infiltration, trapping the sedim...
