The very extensive literature on phosphorus (P) sorption studies is reviewed with the
intention of selecting equations and parameter values for use in a soil P dynamics model …

This paper reviews simplified process models for denitrification. More than fifty models were
considered. The majority of these (simple) models are based on potential denitrification …

The HYPE model is a hydrological model for small-scale and large-scale assessments of
water resources and water quality, developed at the Swedish Meteorological and …

Since the pioneering work of CT de Wit in the 1960s, the Wageningen group has built a
tradition in developing and applying crop models. Rather than focusing on a few models …

An evolving, living organic/inorganic covering, soil is in dynamic equilibrium with the
atmosphere above, the biosphere within, and the geology below. It acts as an anchor for …

Prediction of nitrate leaching from cropland is crucial for preventing surface or ground water
degradation. Accurate modeling of nitrate leaching requires simulations of both soil …

Water flow and solute transport in top soils are important elements in many environmental
studies. The agro-and ecohydrological model SWAP (Soil-Water-Plant-Atmosphere) has …

This study concentrates on eutrophication effects in shallow lakes and ponds on the one
hand and in ditches (small water channels in agricultural areas) on the other. In shallow …

A new model has been developed for assessing the effects of multiple sources of
phosphorus on the water quality and aquatic ecology in heterogeneous river systems. The …

Eutrophication of drainage ditches by over-fertilization with nitrogen and phosphorus causes
a shift from a mainly submerged aquatic vegetation to a dominance of duckweed. This …
