In this study we develop and test a calibration approach on a spatially distributed groundwater–surface water catchment model (MIKE SHE) coupled to a land surface model component with particular focus on the water and energy fluxes. The model is ca

Comparison of simulated water, nitrate, and bromide transport using a Hooghoudt-based and a dynamic drainage model

Autor: Mikkel Mollerup, Søren Hansen, Per Abrahamsen, Carsten T. Petersen

Publikováno v: Water Resources Research. 50:1080-1094

For large-scale hydrological modeling, the accuracy of the models used is a trade-off with the computational requirements. The models that perform well on the daily/meter scale may not perform well when applied at the yearly/kilometer scale. We compa

Publikováno v: Computers & Geosciences. 34:861-875

We combined an inverse routine for assessing the hydraulic soil parameters of the Campbell/Mualem model with the power series solution developed by Philip for describing one-dimensional vertical infiltration into a homogenous soil. We based the estim

Philip’s infiltration equation for variable-head ponded infiltration

Autor: Mikkel Mollerup

Publikováno v: Journal of Hydrology. 347:173-176

Summary Often the Philips infiltration equation has been applied as a fitting equation or as the subsurface component in run-off models. Many a time, the theoretical assumptions for the theory have not been fulfilled. Originally Philip showed that th

Application of water saving irrigation strategies in agriculture has become increasingly important. Both modelling and experimental work are needed to gain more insights into the biological and physical mechanisms in the soil–plant system, which re

Drip irrigation can be an effective way to improve water and nitrogen use efficiency in soil and hence to reduce the environmental pollution. In the EU project SAFIR (http://www.safir4eu.org/) a potato experiment was carried out in lysimeters on thre
