Results from ADP showed that the net water balances show the Contas River as a net water exporter, whereas the Jaguaribe River Estuary is a net water importer. At the Jaguaribe Estuary, water retention during flood tide contributes to 58% of the total volume transferred during the ebb tide from the middle to lower estuary. However, 42% of the total water volume (452 m ) that entered during flood tide is retained in the middle estuary. In the Contas River, 90% of the total water is retained during the flood tide contributing to the volume transported in the ebb tide from the middle to the lower estuary. Outflows obtained with the rating curve method for the Contas and Jaguaribe Rivers were uniform through time due to river flow normalization by dams in both basins. Estimated outflows with this method are about 65% (Contas) and 95% (Jaguaribe) lower compared to outflows obtained with ADP. This suggests that the outflows obtained with the rating curve method underestimate the net water balance in both systems, particularly in the Jaguaribe River under a semi-arid climate. This underestimation is somewhat decreased due to wetter conditions in the Contas River basin. %8 July %N 14 %T Comparative analysis of rating curve and ADP estimates of instantaneous water discharge through estuaries in two contrasting Brazilian rivers %@electronicmailaddress %@electronicmailaddress %@electronicmailaddress rmarins@labomar.ufc.br %@secondarytype PRE PI %K tropical river, river discharge, ADP, rating curve, estuary. %@usergroup administrator %@usergroup lattes %@usergroup marciana %@group %@group %@group CRN-CCR-INPE-MCT-BR %@e-mailaddress rmarins@labomar.ufc.br %3 Dias-86_Hydrology_of_the_Contas_vs_Jaguaribe_River[1].pdf %@secondarykey INPE--PRE/ %@secondarymark B2_CIÊNCIA_DA_COMPUTAÇÃO A2_CIÊNCIAS_AGRÁRIAS_I A2_ECOLOGIA_E_MEIO_AMBIENTE A1_ENGENHARIAS_I A2_GEOCIÊNCIAS A2_GEOGRAFIA A1_INTERDISCIPLINAR %F lattes: 9481839351821903 3 SilvaDiasLaceMariPaul:2011:CoAnRa %@issn 0885-6087 %2 dpi.inpe.br/plutao/2011/06.11.13.33.57 %@affiliation Departamento de Oceanografia Física, Instituto Oceanográfico da Universidade de São Paulo %@affiliation Departamento de Oceanografia Física, Instituto Oceanográfico da Universidade de São Paulo %@affiliation Instituto Nacional de Pesquisas Espaciais (INPE) %@affiliation Departamento de Ciências Agrárias e Ambientais, Universidade Estadual de Santa Cruz, Ilhéus BA %@project CNPq 573Ð601/2008-9. %B Hydrological Processes %@versiontype publisher %P 2188-2201 %4 dpi.inpe.br/plutao/2011/06.11.13.33.56 %@documentstage not transferred %D 2011 %V 25 %@doi 10.1002/hyp.7972 %O Setores de Atividade: Captação, tratamento e distribuição de água, Educação, Outras atividades de serviços. %A Dias, Francisco José da Silva, %A Lacerda, Luiz Drude, %A Marins, Rozane Valente, %A Paula, Francisco Carlos Fernandes de, %@dissemination WEBSCI; PORTALCAPES; MGA; COMPENDEX. %@area GEST
