It rises from the need to obtain reliable data of discharges under the particular morphological conditions that determine the hydrodynamic behaviour of the coastal plain Quequén Grande River estuary (Buenos Aires, Argentina), in which the tide behaves as a standing wave. The technique is calibrated with direct measurements of discharges performed with an acoustic Doppler current profiler in field studies during periods of poor and abundant rains. It is found that the exchange of water with the sea is proportional to the time derivative of the height of the free surface, and the fluvial discharge can be estimated from the height difference between monitoring stations. The results make it possible to quantify the river contribution during dry and wet seasons, and the flows generated by occasional and unusual tides. The method proposed is simple, does not require complex instruments to continuously measure velocity, and takes advantage of existing monitoring nets to provide the information of the estuarine flows in real time and of historic files to evaluate the changes produced in the past.</p></div>","PeriodicalId":42124,"journal":{"name":"RIBAGUA-Revista Iberoamericana del Agua","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.riba.2016.01.001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"55050812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The selected framework consists on the implementation of hydrodynamic models to reproduce the mean sea level elevation induced by the presence of tropical cyclones on the coast. For this, we used synthetic events (120 events) generated in the Atlantic Ocean during the defined time period between 1980–2010 and limited to a 100<!--> <!-->km circular region around the mouth of the Panuco River in Mexico (22.26°N, 97.78°W), together with historical events (25) occurring between 1951 and 2012.
