| Summary: | Nowadays it is discussed the necessity of preservation of the hydro resources availablefor consumption. Once the human beings have the consumption of water as somethingessencial for the life, since early they valued water near their houses. This preocupationcontinue, although during the last decade, the progressive destructions of nature waterreservoirs are observated. Among the depredating actions are: polution, contaminated riversand deforestation of ciliary woods near the rivers that become easy and fast the erosiveprocesses.The state of Maranhão, besides is in Northeast, has different physical characteristicsfrom the rest of the region. The drainage basins that are distributed through the Maranhão arecomposed of principal perennial rivers and tributaries that are sometimes perennial andtemporary. In the Munin river basin, the growing urbane evolution results in seriousenvironmental consequences in its way. The stretch studied, in Chapadinha-Maranhão, hassuffered quick erosive process and consequently the silting on the riverbanks.So in this work we intend to identify the principal agents and processes that spoil thefluvial environment provoking the erosion on the banks and the silting of the watercourse. |
