How to deal with nonlinearities in the modeling of complex subsurface processes?

a cargo de

a cargo de: Denis Voskov (TU Delft)

Día:  Jueves 10 de Mayo a las 12:15 h

Lugar: Departamento de Ingeniería Civil y Ambienta, Modulo D2-Aula CIHS, Planta Baja


The nonlinear nature of complex flow and transport in porous media requires a linearization of governing equations for the numerical solution. In my talk, I will describe two flexible and efficient techniques for the linearization and present results from two different simulation codes based on these techniques. The first technique is based on automatic differentiation approach, which was adapted for reservoir simulation in our Automatic Differentiation General Purpose Research Simulator (ADGPRS) developed at Stanford. The current version of ADGPRS supports coupled thermal-compositional-mechanics processes for naturally fractured media with various schemes of nonlinear coupling. Recently, this framework was extended for fracture propagation which I will describe in more details. The second simulation code Delft Advanced Research Terra Simulator (DARTS) is based on a recently proposed linearization strategy, capable to deal with complex nonlinear problems. This approach approximates exact physics of simulation model which is conceptually similar to an approximate representation of space and time discretization performed in conventional simulation. I present a resolution study in parameter space for highly heterogeneous reservoirs and different physical kernels including complex thermal-compositional description. The proposed linearization approach can also serve as an initial step in creating of physics-based data-driven proxy-models for complex subsurface processes. I will discuss ongoing developments and possible extensions of the proposed methodology as well as other research directions in our group.

Dynamic modelling of geochemical (C, N, P, Fe, O, S) fluxes in lakes using a coupled water-column and sediment diagenesis model

a cargo de: I. Markelov, R.-M. Couture, P. Van Cappellen

Día:  Jueves 03 de Mayo a las 12:15 h

Lugar: Departamento de Ingeniería Civil y Ambienta, Modulo D2-Aula CIHS, Planta Baja


We updated the 1D physical model of lake and coupled it to a vertically resolved sediment diagenesis module. Also, we built biogeochemical reaction network seamlessly coupling water column and sediment processes. The application of the model to a boreal lake shows the capacity of the model to simulate daily water quality and sediment-water exchange fluxes dynamically over a long historical period.
In our prognostic scenarios, we studied the importance of sediment as well as we tested the effects of various climatic and anthropogenic driving forces on biogeochemical cycles in Lake Vansjo. First, coupled Lake-Sediment model was used to study the effect of increasing air temperature on water quality. Secondly, given the chief role of ice cover in controlling water column and biogeochemical cycles, we also examined extreme scenarios of presence and total absence of ice cover. Thirdly, in the artificial scenario with a complete cut-off of the phosphorus loading from the watershed to the lake, we assessed an internal capacity of the lake to preserve phosphorus in water over time. Finally, due to many efforts to improve water quality have relied on the addition of reactive material to the water column, we investigated the influence of iron addition on the DIP flux from the sediment and, consequently, phytoplankton in Lake Vansjo.

Petrophysical and geophysical techniques to characterize seawater intrusion (SI) and submarine groundwater discharge (SGD)

a cargo de: Laura Martinez (PhD)

Día: Jueves 26 de Abril a las 12:15 h
Lugar: Departamento de Ingeniería Civil y Ambiental, Modulo D2-Aula CIHS, Planta Baja


Coastal zones are increasingly demanded spots for human settlements and economic development, which subject alluvial coastal aquifers to the threat of seawater intrusion (SWI). But they are also strategic areas for the chemical exchange between the continent and marine ecosystems, providing a source of nutrients from the submarine groundwater discharge (SGD) from the aquifer. Furthermore, in these contexts, the characteristics of the freshwater-seawater interface (FW-SWI) and its dynamics are strongly conditioned by the lithology and, among others, the typology of the discharge, density contrasts and tides.

The proper management of such enclaves requires full understanding of the SWI-SGD system, which can only be achieved through a multidisciplinary and multi-scale characterization of the considered aquifer. For that purpose, we have developed an experimental field site in a coastal alluvial aquifer close to the mouth of a temporary stream in the Maresme coast line (Barcelona, Spain). The aquifer is formed by unconsolidated heterogeneous and polygenic alluvial sediments ranging from very fine to very coarse grained sand with discontinuous interfingering lenses of gravel and silt. All these sediments have around 25-30 m thickness and are overlying a weathered granitic basement. Several boreholes were drilled perpendicular and parallel to the shoreline, at various depths to reach different hydraulic conductivity areas along the mixing zone.

Here, we present the geophysical techniques including electrical resistivity tomography and different types of logging (natural gamma ray, spectral gamma ray, induction and magnetic susceptibility) that have been performed to distinguish sedimentary bodies and characterize the salinity gradient. Also lithological description, sedimentological correlation and geochemical analysis of the cores obtained after drilling were integrated to characterize the initial stage of the experimental site.



Simulating the effect of distinct irrigation scheduling strategies and soil hydraulic properties on crop yield and water balance

a cargo de: Mireia Fontanet

Dia: Jueves 19 de abril a las 12:15 h
Lugar:  Departamento de Ingeniería Civil y Ambienta, Modulo D2-Aula CIHS, Planta Baja


In a context of climate change evidence and the fact that agriculture uses about 70% of total available water for irrigation in semi-arid areas, there is an increasing probability of local water scarcity scenarios; therefore, water optimization is one of the main goals of researchers and stakeholders in irrigated agriculture.

Irrigation scheduling is the process by which irrigation system managers adjust frequency event and duration to guarantee maximum yield, avoid salt buildup in the root zone and maximize profitability with the minimum volume of water applied. Irrigation event Frequency can be set by defining the Plant Available Water (PAW) level to trigger the moment to irrigated, and thus, avoid soil water stress. Irrigation event Duration is related to the volume of water is applied to refill root zone moisture content.

The main methodologies to assess irrigation scheduling strategies and tactics are based on water balance budget, plant stress monitoring and soil moisture monitoring; usually, the manager combines different information strains and methodologies to adapt to each soil type, cropping system and weather conditions. Each methodology has limitations and not all take in account how water moves in the soil when it is infiltrated, or in another words, they do not consider soil type and structure. In this work, we have simulated, with HYDRUS software, different irrigation strategies with different combinations of frequencies and irrigation durations in different soil types. Water balance components and an economical analysis have been computed to determine the best irrigation strategy to guarantee the maximum yield with minimum water in each soil. Results show that depending on soil type and its hydraulic properties, irrigation scheduling should be managed different affecting crop yield and water balance components.
