Abstract
The basin of the dam Camará - PB presents great diversity of landscapes, especially in relation to landform, soil. Its importance lies in concerns about the conservation of the environment and the socio-economic development and preservation of natural resources in the area in search of integrated and sustainable development. This study aimed to contribute to developing a map of Camará erodibility of the basin for future research and projects that improve environmental conservation. Thus, there were collection and analysis of the soil, drawing up a map of slope, for more accurate results. Was used in this study an image of CBERS, for 2004 and geoprocessing techniques using the program SPRING, descriptive basis for the work field, where it was collected GPS control points for observation. From the information of soil and topography, we described the areas susceptible to erosion. The results obtained in the watershed data showed that in his 19 geoenvironmental units present most of the strong wavy relief and soils Regosols, deep and well drained.
Highlights
A watershed is a unit of territorial management of water resources and has an integrative character of the dynamics that occur in environmental units, revealing excellent study areas for planning (Hidalgo, 1992)
The catchment area of the dam Camará has an area of 104 km2, and is contained in the upper quadrangle whose geographical coordinates are 60 58'20'' 45'40'' South and 350 West, and less than 70 04'40'' south and 350 53'40'' west
The basin is located on the Camará Borborema Plateau, and covers part of the Considering the attributes related to natural components, soil and topography, and the socio-economic, related to land use, Silva (2006) separated nineteen geoenvironmental units in the basin Camará, shown in Figure 3, coded by numbers and colors
Summary
A watershed is a unit of territorial management of water resources and has an integrative character of the dynamics that occur in environmental units, revealing excellent study areas for planning (Hidalgo, 1992). It is represented by different ecological units, which define its natural characteristics, socioeconomic and political. The dam had a capacity to store about 27 million m3 of water, only 65% capacity, on June 17, 2004, occurred the rupture of its wall, causing serious material damage and human (Nieble, 2004)
