Water suppliers in parts of Europe currently face occasional Drinking Water Directive compliance challenges for a number of pesticide active substances including metaldehyde, clopyralid and propyzamide. Water Framework Directive (WFD) Article 7 promotes a prevention-led (catchment management)...

The DRAINMOD-N II model (version 6.0) was evaluated for a cold region in south-east Sweden. The model was field-tested using four periods between 2002 and 2004 of climate, soil, hydrology and water quality data from three experimental plots, planted to a winter wheat-sugarbeet-barley-barley crop...

Adequate knowledge on the movement of nitrate-nitrogen (NO3-N) under different subsurface (tile) drain configurations and management practices in the U.S. Midwest is essential for developing remedial measures for reducing hypoxic conditions in the Gulf of Mexico. In this study, DRAINMOD-NII, a...

Nitrate-nitrogen (NO3-N) loading from a 734ha coastal watershed draining into the Baltic Sea off south-east Sweden was simulated using a simple modelling approach in which the nitrogen model DRAINMOD-N II and a temperature-dependent NO3-N removal equation were incorporated into the Arc...

Rising ocean levels have resulted in increasingly severe flooding in numerous metropol-itan coastal areas. What would it cost to minimize or eliminate such damage? Relatively little economic work has been done to provide an answer, at least partially because some authori-ties believe attempts to...

Faster, frictionless, cheaper, better: these are said to be the hallmarks of economic activity on the Internet. Search theory suggests use of the Net could reduce the prices consumers pay, but product branding, price discrimination based on data mining, and auctions may raise prices. The Net has...
