Resumo: This research aims to associate the spatial variation of rainfall and relief for water availability in the Apodi/Mossoró River Basin (RN, Brazil). A series of temporal rainfall data (mm) was used between the years 1983 to 2013, of 38 monitoring stations located along the study area, obtained from the database provided by the institutions ANA, CPRM, EMPARN and SUDENE. The data were submitted to the geostatistical interpolation procedure, by the inverse distance weighting method (IDW). The division was observed in well-defined pluviometric sub-regions: in the section that includes the high course of the Apodi/Mossoró River, rainfall is between 821 and 1,284 mm; rainfall levels between 742 and 821 mm dominate most of the middle course; and in the low course, was characterized by the drier climate, since the rainfall index oscillates between 534 to 742 mm. The results corroborated the influence of the domain of residual masses (plateaus in the order of 700 and 750 m) in rainfall, in the initial stretches of the hydrographic basin. Therefore, the atmospheric dynamics conditions and the heterogeneity of the relief morphology influence the temporal and spatial variations of the pluviometric precipitation of the study area.

Se utilizaron una serie de datos temporales de precipitación pluviométrica (mm) entre los años 1983 a 2013, de 38 puestos de monitoreo localizados a lo largo del área de estudio, obtenidos a partir de la base de datos disponibilizada por las instituciones ANA, CPRM, EMPARN y Sudene. Los datos fueron sometidos al procedimiento geoestadí­stico de interpolación, por el método de ponderación por el inverso de la distancia (IDW). Se observó la división en subregiones pluviométricas bien definidas: en el tramo que engloba el alto curso del Rí­o Apodi / Mossoró, las precipitaciones están entre 821 a 1.284 mm; los niveles de lluvias entre 742 a 821 mm dominan mayor parte de la porción del medio curso; y en el bajo curso, fue caracterizado por el clima más seco, una vez que los í­ndices de lluvias oscilan entre 534 a 742 mm. Los resultados corroboraron la influencia del dominio de macizos residuales (platós en el orden de 700 y 750 m) en la pluviometrí­a, en los tramos iniciales de la cuenca hidrográfica. Por esta razón, las condiciones de la dinámica atmosférica y heterogeneidad de la morfologí­a del relieve influencian en las variaciones temporales y espaciales de la precipitación pluviométrica del área de estudio.Esta pesquisa objetiva associar a variação espacial da pluviometria e relevo, para disponibilidade hí­drica na Bacia Hidrográfica do Rio Apodi/Mossoró (RN, Brasil). Foram utilizados uma série de dados temporais de precipitação pluviométrica (mm) entre os anos de 1983 a 2013, de 38 postos de monitoramento localizados ao longo da área de estudo, obtidos a partir do banco de dados disponibilizado pelas instituições ANA, CPRM, EMPARN e SUDENE. Os dados foram submetidos ao procedimento geoestatí­stico de interpolação, pelo método de ponderação pelo inverso da distância (IDW). Foi observada a divisão em sub-regiões pluviométricas bem definidas: no trecho que engloba o alto curso do Rio Apodi/Mossoró, as precipitações estão entre 821 a 1.284 mm; os ní­veis de chuvas entre 742 a 821 mm dominam maior parte da porção do médio curso; e no baixo curso, foi caracterizado pelo clima mais seco, uma vez que os í­ndices de chuvas oscilam entre 534 a 742 mm. Os resultados corroboraram a influência do domí­nio de maciços residuais (platôs na ordem de 700 e 750 m) na pluviometria, nos trechos iniciais da bacia hidrográfica. Portanto, as condições da dinâmica atmosférica e heterogeneidade da morfologia do relevo influenciam nas variações temporais e espaciais da precipitação pluviométrica da área de estudo.Universidade do Estado do Rio Grande do Norte (UERN)2018-12-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersion Peer reviewed Revisado por paresAvaliado pelos paresapplication/pdfhttps://periodicos.apps.uern.br/index.php/GEOTemas/article/view/899Journal Geotemas; Vol. 8 No. 3 (2018): Revista Geotemas; 29-41Revista Geotemas; Vol. 8 Núm. 3 (2018): Revista Geotemas; 29-41Revista Geotemas; v. 8 n. 3 (2018): Revista Geotemas; 29-412236-255Xreponame:Revista Geotemasinstname:Universidade do Estado do Rio Grande do Norte (UERN)instacron:UERNporhttps://periodicos.apps.uern.br/index.php/GEOTemas/article/view/899/811Copyright (c) 2018 REVISTA GEOTEMASinfo:eu-repo/semantics/openAccessMedeiros, David Hélio Miranda de Cavalcante, Andrea Almeida Pinheiro, Lidriana de Souza 2020-06-22T15:14:53Zoai:ojs2.periodicos.apps.uern.br:article/899Revistahttp://periodicos.apps.uern.br/index.php/GEOTemas/indexPUBhttp://periodicos.apps.uern.br/index.php/GEOTemas/oaigeotemas@uern.br||josielguedes@yahoo.com.br2236-255X2236-255Xopendoar:2020-06-22T15:14:53Revista Geotemas - Universidade do Estado do Rio Grande do Norte (UERN)false
