%X Pour d¨¦finir les impacts environnementaux associ¨¦s ¨¤ l'occupation humaine dans des secteurs caract¨¦ris¨¦s par l'apport de s¨¦diments (bypass) sur la plage, via des champ de dunes et l¡¯estuaire, ont ¨¦t¨¦ r¨¦alis¨¦es des ¨¦tudes g¨¦o-environnementales dans la plaine c ti¨¨re du Caponga, en y incluant un promontoire, une bande littorale et l¡¯embouchure du canal estuarien de m¨ºme nom. Les r¨¦sultats ont ¨¦t¨¦ repr¨¦sent¨¦s dans des mod¨¨les ¨¦volutifs, int¨¦gr¨¦s ¨¤ partir de la d¨¦finition des flux de mati¨¨re et d'¨¦nergie qui transitent dans la zone c ti¨¨re. Les cons¨¦quences de l'expansion urbaine sur le promontoire, les dunes, la plage et le canal estuarien ont ¨¦t¨¦ caract¨¦ris¨¦es afin de d¨¦finir des mesures adapt¨¦es de planification et de gestion. Environmental impacts caused by the occupation of areas regulating the sand input to the coast line in the coastal plain of Caponga, Cascavel town, East Coast of Cear¨¢. To determine the environmental impacts related to human occupation in areas characterized by the input of sediments (bypass) to the coastal line, through dunes and estuary, we carried out geoenvironmental studies in the coastal plain of Caponga. They included sections represented by a headland, coastal line and river mouth of the estuarine channel of Caponga. The results were represented in integrated evolutionary models based on the definition of flows of matter and energy that occur in the coastal area. The effects of urban expansion on the headland, dunes, shore and estuarine channel were characterized so as to define adequate measures of planning and management. Para definir os impactos ambientais associados ¨¤ ocupa  o humana em ¨¢reas caracterizadas pelo aporte de sedimentos (bypass) para a faixa de praia, via campo de dunas e estu¨¢rio, foram realizados estudos geoambientais na plan¨ªcie costeira da Caponga, abrangendo setores representados por um promont¨®rio, faixa litoranea e desembocadura do canal estuarino de mesmo nome. Os resultados foram representados em modelos evolutivos, integrados a partir da defini  o dos fluxos de mat¨¦ria e energia que transitam na zona costeira. As conseq¨¹¨ºncias da expans o urbana sobre o promont¨®rio, dunas, praia e canal estuarino foram caracterizadas de modo a definir medias adequadas de planejamento e gest o.
