Abstract

The hydro-agricultural zones in the Capim river basin (Eastern Amazonia) were identified using the variations of the landscape model and the dynamics of the surface runoff. The evaluation variables were: morphometry basin and the relief-forming parameters, the distribution of rainfall, and the land use classes. The results indicated the segmentation of the basin in Medium-High and the Medium-Low curse, with distinct degrees of alteration. Where the most vulnerable regions belong to the Capim river valley in watersheds smaller than 700 km², and the priorities for agricultural use in topographic boundaries; which reinforces the need for a basin plan that orders the sector and recovers these areas. The Amazon basins need effective control and quantitative and qualitative monitoring of water to improve agricultural production and human supply.
