By: B. M. Jackson; C. J. Daughney; U. Morgenstern; M. R. Guggenmos

Description: School of Geography, Environment and Earth Sciences, Victoria University of Wellington, Wellington, New Zealand. Identifying areas of interaction between groundwater and surface water is crucial for effective environmental management, because this interaction is known to influence water quantity and quality. This paper applies hydrochemistry and multivariate statistics to identify locations and mechanisms of groundwater-surface water inte...

Incorporation of Groundwater Losses and Well Level Data in Rainfal...

By: R. J. Moore; V. A. Bell

Description: Centre for Ecology and Hydrology, Wallingford, Oxon, OX10 8BB, UK. Intermittent streamflow is a common occurrence in permeable catchments, especially where there are pumped abstractions to water supply. Many rainfall-runoff models are not formulated so as to represent ephemeral streamflow behaviour or to allow for the possibility of negative recharge arising from groundwater pumping. A groundwater model component is formulated here for use in extending ...

By: F. Zabel; W. Mauser; T. B. Hank

Description: Department of Geography, Ludwig-Maximilians-Universität, Munich, Germany. Regionalization of physical land surface models requires the supply of detailed land cover information. Numerous global and regional land cover maps already exist but generally, they do not resolve arable land into different crop types. However, arable land comprises a huge variety of different crops with characteristic phenological behaviour, demonstrated in this paper with Leaf ...
