Dynamical process upscaling for deriving catchment scale state variables and constitutive relations for meso-scale process models
In this study we propose an uspcaling approach to derive time series of (a) REW scale state variables, and (b) effective REW scale soil hydraulic functions to test and parameterise models based on the REW approach. To this end we employed a physically based hydrological model, that represents the typical patterns and structures in the study catchment, and has previously been shown to reproduce ...

متن کاملTowards a new generation of hydrological process models for the meso-scale: an introduction
The main motivation for this special issue of Hydrology and Earth System Sciences is the IAHS decadal research initiative “Predictions in Ungauged Basins” (Sivapalan et al., 2003), and more specifically the need to develop hydrological models that work for the “right reasons” (Kirchner, 2006). This means that a model shall “work” because its structure is based on appropriate representation of t...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Point process models of rainfall: Developments for fine-scale structure
A conceptual stochastic model of rainfall is proposed in which storm origins occur in a Poisson process, where each storm has a random lifetime during which rain cell origins occur in a secondary Poisson process. In addition, each cell has a random lifetime during which instantaneous random depths (or ‘pulses’) of rain occur in a further Poisson process. A key motivation behind the model formul...
