Riparian Buffer Strip Width Design in Semiarid Watershed Brazilian | Chapter 09 | Advances and Trends in Agricultural Sciences Vol. 1
The use of
riparian areas as water quality management tools, primarily derived from the
studies of agricultural watersheds, where low phosphorus and large nitrate
reductions in the suspended sediment are observed. A riparian strip performs
many key functions, such as nutrient uptake, trapping of sediment or
pesticides. Therefore, a number of different forms of protection strips have
been applied in the field according to relief, steepness and location for use.
Studies assessing technologies to design riparian strips using plant covers,
based on sediment yield in river basins, are required for environmental
protection. The removal of semi-shrubby, native vegetation in the Brazilian
semiarid region, has contributed to the degradation of semiarid basins. The aim
of this study was to design a riparian strip for the Jacu River in the semiarid
region of Pernambuco as a function of sediment yield. Experiments were
conducted during the years 2008-2011 in the Jacu River basin at Serra Talhada,
Pernambuco State, Brazil. The sediment yield in the Jacu River channel was
obtained by measuring suspended and background solid discharge. The riparian
strip width estimated in the riparian areas of the Jacu River basin was 15 m.
It was concluded that for this study, the sediment yield time and observation
of hydrological data were important factors for determining the riparian strip
width with greater security.
