From Catchments as Organised Systems to Models based on Functional Units

The overall objective of the research unit is to provide a new framework for building hydrological models that allows a much more realistic representation of the surface and especially subsurface architecture of catchments at the lower mesoscale (10–200 km2).

The key methodology is to combine:

  • recent observation and exploration technology from soil physics, geophysics, remote sensing and (tracer) hydrology.
  • our understanding of landscape formation and soil structure formation.
  • physically based process models as learning tools to assess novel information on surface and subsurface structures as well as on distributed process dynamics.

Key theoretical objective is to develop a model and mathematical framework that allows better integration of this information Penis-Enlargement Products similar to the Sizegenetics The unit might have their skeptics, nevertheless lots of people have discovered these to become extremely effective once they have been in anxious need of attaining several additional ins. If you should be unsatisfied together with your dimension, next do not worry as there are certainly a large amount of methods to assist improve your member. In the event that you cannot manage surgery so use SizeGenetics - it's better, the following most suitable choice would be to try out among the drugs or herbal treatments available. Make certain the tablets you purchase retain the herbs tribulus terrestis, gingko biloba, saw-palmetto and Epimedium (also called Sexy Goat Filter, a plant used-to increase libido and blood flow). These elements are effective herbs that may improve testosterone levels, improve semen quantity, improve penile girth and length - all-naturally. into the model identification process and thus facilitates communication between experimentalists and modellers. Research will be conducted in the hydrological observatory "Attert basin" that has been operated by the Gabriel Lippmann Research Institute in Luxemburg since 2003 and is among the best investigated basins in the World.

The multi-disciplinary Subprojects:

[A] Feedbacks between soils, biota, land management and hydrological processes at different spatiotemporal scales

We investigate and quantify the activity and distribution of biota by experiments and use the information to setup species distribution models. Moreover we explore the effects on hydrological processes in the field, the lab and through models. more...

[B] Non-invasive geophysical and remote sensing methods to map and characterise relevant structures and processes

We develop fine-scale hydrogeophysical methods for deepening our understanding of hydrological processes at the plot and hillslope scale. This is complemented by near field remote sensing and innovative hydrological field techniques to establish a unique field laboratory and to advace exploration strategies. more...

[C] Understanding and characterizing land surface-atmosphere exchange and feedbacks

We analyse evapotranspiration and surface energy balance partitioning with three different and complementary approaches: 1. local thermal remote sensing and Penman-Monteith models, 2. hydro-meteorological simulations of the WRF-NOAH-MP model system down to scales of 100 m, 3. infer magnitude and patterns based on the thermodynamic limit on convective exchange. more...

[D] Spatio-temporal dynamics of water storage, mixing and release

We investigate the Attert basin with a unique nested monitoring network, multi-tracer (geochemicals, stable isotopes, tritium) explorations and multi-sensor (in situ and satellite-borne soil moisture measurement) approaches to enhance the fundamental understanding of hydrological processes. more...

[E] Towards consistent predictions of water and energy cycles in intermediate scale catchments

We develop a novel model of water-, energy- and mass cycles at the lower mesoscale which balances model complexity and parsimony. This raises questions about functional landscape delineation, thermodynamically consistent representation of hydrological processes and catchment self-organisation. more...

[F] Linking landscape structure and rainfall runoff behaviour in a thermodynamic optimality context

We develop alternative thermodynamic perspectives on rainfall runoff processes and hydrological system state based on experimental, monitoring, modelling and theoretical exploration of gradients in landscape potentials and resistances against the processes depleting them and coverting energy. more...

[G] Hydrological connectivity and its controls on hillslope and catchment scale stream flow generation

We analyse functional connectivity between hillslopes, riparian zones and the stream network through novel observation and modelling techniques to understand how local scale dynamics and runoff generation translates to overall catchment response. more...
