doi: 10.12957/geouerj.2016.15456 The water scarcity problem in Pernambuco semiarid encourages scientific research that aim to understanding the behavior of integrated semiarid river systems, relating the physical system of basins to antropic systems. This perspective the present study characterized the fluvial dynamics of Riacho Grande basin, located in the Sertao de Pernambuco region, applying an integrated manner the proposal of landscape connectivity and rivers styles, generating useful background information for management of water resources at the local scale. Therefore, it was identified the land uses, from data obtained in the field work with the support of GPS and use of QuickBird and SRTM (Shuttle Radar Topography Mission) images; understanding its dynamics and relating them to water infiltration capacity retained in the soil and runoff. The calculation of runoff flow volume was performed by using data extracted from the Agritempo data platform, for the period 1993-2012, through water balance daily sequential. It was identified in the Riacho Grande basin 3 main classes of land use, associated, with the texture and soil structure, the volume of runoff flow in the area. The analysis also identified the drainage impediments, able to retain the drained flow making it impossible them from reaching the network channels. Between main transmission impediments was identified a large number of dams, roads paved and unpaved and floodplains. Finally, the characterization of the channels from the primary analysis of river styles.
