Resumen
The progress of Santa Maria had as one of its consequences the environmental
degradation of urban streams. The importance of this study is given in the
presentation of an alternative and new methods of work for the rehabilitation of rivers
slopes of the city. It was chosen as a stretch of creek Cancela, located in the Park of
CACISM (Câmara de Comércio Indústria e Serviços de Santa Maria) or Park of
Tamanday, between the districts Nossa Senhora Medianeira and Nonoai, in order to
reshape, stabilize and restore ecologically the place building a cribwall vegetated
with Hedychium coronarium. It was aimed to analyze the development of the specie
in the structure by counting the shoots and monitor the stability of the slope. To this
end, the cribwall was divided into three portions: the portion "A" understood the
section near the bridge, the portion "B" was located in the center portion of the
cribwall, and "C" is further upstream. Each plot was subjected to three treatments, as
follows: T1 - water line, T2 - middle of the cribwall and T3 loud of the slope. In 90
days of the experiment, the T1 (water line) obtained the best results, because at this
point the Hedychium coronarium showed a higher number of shoots with an average
of 3.65 shoots per linear meter. In assessing the biotechnical potential of Hedychium
coronarium in the structure, it was shown that this herbal specie can be used by soil
bioengineering, there is need to test other species together. With the action of public
and private sector, residents and the community, were able to observe an innovative
form of environmental remediation. This work enabled the development of new
researches being undertaken by students of the Graduate Forestry at UFSM.
