Coupling of Agricultural Economic and Hydrological Models

German Journal of Agricultural Economics, 2003
The objective of the paper is to show the potential of interdisciplinary model networks consisting of agricultural economic and natural science models performing integrated impact assessments of agri-environmental policies. The potentials are exemplified using a coupling of the agricultural sector model RAUMIS with the hydrological models GROWA98 and ...

The hydrologic behavior of agricultural watersheds

Eos, Transactions American Geophysical Union, 1944
During the past decade there has been much discussion, pro and con, with regard to the effects of agricultural operations upon the amount and regimen of runoff from watersheds. The problem becomes highly involved on large watersheds, because they are made up of various complexes of soil, cover, topography, and other edaphic features.

Evaluation of a surface hydrological connectivity index in agricultural catchments

Environmental Modelling & Software, 2013
Identification of surface hydrological connectivity at scales where critical source areas (CSAs) can be managed is fundamental to achieving effective management of phosphorus loss in agricultural catchments. This study investigated the potential for the 'Network Index' (NI) to predict surface connectivity at CSA-management scales in contrasting ...

Hydrological controls on nutrient concentrations and fluxes in agricultural catchments

Science of The Total Environment, 2002
Like many streams draining intensively farmed parts of lowland Scotland, water quality in the Newmills burn, Aberdeenshire, is characterized by relatively high nutrient levels; mean concentrations of NO3-N and NH3-N are 6.09 mg l(-1) and 0.28 mg l(-1), respectively, whilst average PO4-P concentrations reach 0.06 mg l(-1).
