Data assimilation using the ensemble Kalman filter in a distributed hydrological model on the Tocantins River, Brasil

Autor: Karena Quiroz Jiménez, Walter Collischonn, Rodrigo Cauduro Dias de Paiva

Publikováno v: Revista Brasileira de Recursos Hídricos, Vol 24 (2019)

ABSTRACT In this work, the data assimilation method namely ensemble Kalman filter (EnKF) is applied to the Tocantins River basin. This method assimilates streamflow results by using a distributed hydrological model. The performance of the EnKF is als

Autor: Diego Alonso Arias-Choquehuanca, Brayan Indalecio Campos-Neciosup, Karena Quiroz-Jiménez

Publikováno v: Dyna, Vol 90, Iss 229 (2023)

Floods are a phenomenon that can be triggered by river overflow or heavy rainfall. In this context, detecting flooded areas is crucial to document affected zones in urban environments over time. This study focuses on the development of a model based
