Influ{\^e}ncia tect{\^o}nica na configura{\c{c}}{\~a}o da
paisagem atual da Bacia Para{\'{\i}}ba tem sido sugerida por
caracter{\'{\i}}sticas morfoestruturais derivadas do relevo e

detalhados que possam confirmar a presen{\c{c}}a de estruturas

desta pesquisa foi analisar a influ{\^e}ncia tect{\^o}nica no
desenvolvimento das bacias dos rios Para{\'{\i}}ba e Mamanguape
na por{\c{c}}{\~a}o norte da Bacia Para{\'{\i}}ba (PB) a
partir de t{\'e}cnicas e produtos de sensoriamento remoto. Para
isso, utilizou-se an{\'a}lise de bacias de drenagem e das
caracter{\'{\i}}sticas morfoestruturais com base em modelo
digital de eleva{\c{c}}{\~a}o (MDE) adquirido pela
\emph{Shuttle} Radar \emph{Topography Mission} (SRTM),

extra{\c{c}}{\~a}o da rede de drenagem da {\'a}rea de estudo.
Al{\'e}m de auxiliar na extra{\c{c}}{\~a}o de lineamentos

c{\'a}lculo de {\'{\i}}ndices morfom{\'e}tricos, como o fator
de simetria topogr{\'a}fica transversal (FSTT), que foi {\'u}til
para sugerir influ{\^e}ncia tect{\^o}nica em v{\'a}rias
subbacias da {\'a}rea de estudo. Esse {\'{\i}}ndice revelou
rios com alta assimetria, principalmente, aqueles localizados em
{\'a}reas da cobertura sedimentar, al{\'e}m de evidenciar dois
conjuntos de subbacias com padr{\~o}es de basculamentos
diferenciados. A an{\'a}lise conjunta dos elementos
morfoestruturais das bacias de drenagem pesquisadas permitiu
reunir evid{\^e}ncias em suporte a deforma{\c{c}}{\~o}es

Quatern{\'a}rio tardio e s{\~a}o devidas a

increasing number of publications have shown the influence of
Cenozoic tectonic activities in northeastern Brazil, despite its
localization in a passive margin of the Sulamerican plate.
Tectonic influence in the current landscape configuration of the
Para{\'{\i}}ba Basin has been suggested by morphostructural
characteristics derived from relief and drainage systems. However,
detailed studies to confirm the presence of tectonic structures in
various areas in this basin are lacking. The goal of this work was
to analyze the tectonic influence in the development of the
Para{\'{\i}}ba and Mamanguape river basins, northern of
Para{\'{\i}}ba Basin (PB), from techniques and remote sensing
products. The research was undertaken through the analysis of
drainage basin and of morphostructural characteristics based on
digital elevation model (DEM) acquired by the Shuttle Radar
Topography Mission (SRTM), geomorphometric variables derived from
this product, and multi-polarized radar image from the
PALSAR/ALOS-1 sensor. The results showed that the topographic
coherence was more efficient than the DEM-SRTM to extract the
drainage network of the study area. In addition to help the
extraction of morphostructural lineaments, the DEM-SRTM was also
useful for the calculation of morphometric indices, such as the
Transverse Topographic Symmetry Factor (TTSF), which was useful to
suggest tectonic influence in various sub-basins of the study
area. This index revealed rivers with high asymmetry which mainly
include those located in areas with sedimentary cover, in addition
to highlight two sets of sub-basins with different tilting
patterns. The integrated analysis of morphostructural elements of
the analyzed drainage basins allowed provide evidence to support
tectonic deformation in study area. This was manifested in the
late Quaternary and is due to the reactivation of extensional and
compressive efforts already recorded in the crystalline basement
during sedimentary deposition. This was evidenced by the good
correspondence between the morphostructural lineaments from the
areas with sedimentary cover and those from the Precambrian
crystalline basement. In addition to these results, the present
work also contributed to the morphological characterization of
residual deposits related to a delta located at the
Para{\'{\i}}ba Riverīs mouth. Arithmetic operations using
PALSAR/ALOS-1 images were essential for generating a data set that
allowed the best characterization of the studied deltaic feature.
Spatial filtering techniques (i.e., mean and directional
filtering) allowed highlight this paleomorphology, in addition to
help discriminating details of morphologies corresponding to its
sedimentary sub-environments. The cuspate morphology and the
presence of curvilinear features attributed to beach ridges and
paleoshoreline validated the hypothesis that the investigated
paleomorphology corresponds to residual deposits of a
wave-influenced paleodelta. The combination of morphological and
chronological data suggest that this delta was formed during the
past 2.140 \$\pm\$ 144 years, i.e., after the mid-Holocene
sea-level fall. However, the interpretation obtained from the
morphostructural analysis led to propose that its genesis might
have also been driven by tectonic factor.",
