Data Assimilation as a Tool to Improve Chemical Transport Models Performance in Developing CountriesLopez Restrepo, S. (author), Yarce Botero, A. (author), Quintero Montoya, O.L. (author), Pinel Pelaez, N. (author), Hinestroza Ramirez, J.E. (author), Nino-Ruiz, Elias David (author), Anderson Flórez, Jimmy (author), Rendón, Angela Maíra (author), Alvarez-Laínez, Monica Lucia (author), Heemink, A.W. (author)Particulate matter (PM) is one of the most problematic pollutants in urban air. The effects of PM on human health, associated especially with PM of ≤2.5μm in diameter, include asthma, lung cancer and cardiovascular disease. Consequently, major urban centers commonly monitor PM2.5 as part of their air quality management strategies. The Chemical...book chapter 2021

(author)This chapter book presents Medellín Air qUality Initiative or MAUI Project; it tells a brief story of this teamwork, their scientific and technological directions. The modeling work focuses on the ecosystems and human health impact due to the exposition of several pollutants transported from long-range places and deposited. For this objective,...book chapter 2021

Heemink, A.W. (author), Umer Altaf, M. (author), Barbu, A.L. (author), Verlaan, M. (author)Variational data assimilation, also sometimes simply called the ‘adjoint method’, is used very often for large scale model calibration problems. Using the available data, the uncertain parameters in the model are identified by minimizing a certain cost function that measures the difference between the model results and the data. A variational...conference paper 2013

Huber, E. (author), Spivakovskaya, D. (author), Lin, H.X. (author), Heemink, A.W. (author)Last several years the ship accidents caused the serious ecological catastrophes in the seaside of different countries. To prevent or, at least, reduce the possible damage due to accidents we need to develop efficient and accurate model for the simulation of the pollution spreading. The movement of the pollutant can be modeled by using a random...conference paper 2006

Spivakovskaya, D. (author), Deleersnijder, E. (author), Heemink, A.W. (author)Large scale diffusion processes in the ocean occur mostly along isopycnal surfaces, i.e. surfaces of equal density. However, there is also diapycnal diffusion, which is associated with a diffusion flux orthogonal to isopycnal surfaces. The diapycnal and isopycnal diffusion fluxes are commonly parameterized a la Fourier-Fick, a formulation...conference paper 2006

Jesus de Moraes, R. (author), Fonseca, R.M. (author), Helici, M. (author), Heemink, A.W. (author), Jansen, J.D. (author)In this work, the application of tensor methodologies for computer-assisted history matching of channelized reservoirs is explored. A tensor-based approach is used for the parameterization of petrophysical parameters to reduce the dimensionality of the parameter estimation problem. Building on the work of Afra and Gildin (2013); Afra et.al. ...conference paper 2017

de Zeeuw, W. (author), Jesus de Moraes, R. (author), Heemink, A.W. (author), Jansen, J.D. (author)We propose a novel adaptive, adjoint-based, iterative multiscale finite volume (i-MSFV) method. The method aims to reduce the computational cost of the smoothing stage of the original i-MSFV method by selectively choosing fine-scale sub-domains (or sub-set of primary variables) to solve for. The selection of fine-scale primary variables is...conference paper 2019

Vermeulen, P.T.M. (author), Te Stroet, C.B.M. (author), Heemink, A.W. (author)Despite increasing computational resources many high?dimensional applications are impractical for model inversions. In this paper, two methods are presented that are promising for high?dimensional model inversion. The methods draw on proper orthogonal decomposition (POD) and yield reduced models that describe a truncated behavior of the original...journal article 2006

Vermeulen, P.T.M. (author), Te Stroet, C.B.M. (author), Heemink, A.W. (author)Different upscaling methods for groundwater flow models are investigated. A suite of different upscaling methods is applied to several synthetic cases with structured and unstructured porous media. Although each of the methods applies best to one of the synthetic cases, no performance differences are formed if the methods were applied to a real...journal article 2006
