Using hydrological models and geographic information systems to assist with the management of surface water in agricultural landscapes

Geographical information systems (GIS), remote sensing, and the various analytical tools associated with them, are increasingly able to provide sources of data and means of manipulating data appropriate for large scale management of resources. A major management concern in western Canada is the conflict between the desire of farmers to drain or consolidate small bodies of non-permanent surface water and the possible onand off-site effects of such land drainage.
