The contribution of soil structural degradation to catchment flooding: a preliminary investigation of the 2000 floods in England and Wales.

Holman, Ian P.; Hollis, J. M.; Bramley, M. E.; Thompson, T. R. E. (European Geophysical Society / Copernicus Publications, 2003-01-01)

During the autumn of 2000, England and Wales experienced the wettest conditions for over 270 years, causing significant flooding. The exceptional combination of a wet spring and autumn provided the potential for soil ...
Using a linked soil model emulator and unsaturated zone leaching model to account for preferential flow when assessing the spatially distributed risk of pesticide leaching to groundwater in England and Wales

Holman, Ian P.; Dubus, Igor G.; Hollis, J. M.; Brown, Colin D. (Elsevier Science B.V., Amsterdam., 2004-01-05)

Although macropore flow is recognized as an important process for the transport of pesticides through a wide range of soils, none of the existing spatially distributed methods for assessing the risk of pesticide leaching ...
Validation of an intrinsic groundwater pollution vulnerability methodology using a national nitrate database.

Holman, Ian P.; Palmer, R. C.; Bellamy, Patricia H.; Hollis, J. M. (Springer Science Business Media, 2005-10-01)

The importance of groundwater for potable supply, and the many sources of anthropogenic contamination, has led to the development of intrinsic groundwater vulnerability mapping. An Analysis of Co-Variance and Analysis ...
