Influence of Climate and Land Use Change on the Groundwater System of the Veluwe, The Netherlands: A Historical and Future Perspective

Autor: Marjolein H. J. Van Huijgevoort, Bernard R. Voortman, Sjoerd Rijpkema, Kelly H. S. Nijhuis, Jan-Philip M. Witte

Publikováno v: Water, Vol 12, Iss 10, p 2866 (2020)

Changes in land use and climate have a large influence on groundwater recharge and levels. In The Netherlands, precipitation shifts from summer to winter are expected, combined with an increase in summer temperature leading to higher evaporation. The

Technical Note: A Device to Directly Measure Transpiration from Vegetation Grown in Containers

Autor: Stefanie Pflug, Bernard R. Voortman, Jan-Philip M. Witte

Publikováno v: Water, Vol 12, Iss 2, p 355 (2020)

Information about evaporation and transpiration fluxes is vital for water budgets, modeling of water flows and climate, as well as for assessing the hydrological impact of land management practices. Under natural conditions, these fluxes are difficul

Forensic Hydrology Reveals Why Groundwater Tables in The Province of Noord Brabant (The Netherlands) Dropped More Than Expected

Autor: Jan-Philip M. Witte, Willem Jan Zaadnoordijk, Jan Jaap Buyse

Publikováno v: Water, Vol 11, Iss 3, p 478 (2019)

Since the nineteen fifties, groundwater levels in the Netherlands dropped more than as simulated by hydrological models. In the rural sandy part of the Netherlands, the difference amounts to approximately 0.3 m on average. The answer to the question

Trait Estimation in Herbaceous Plant Assemblages from in situ Canopy Spectra

Autor: Hans D. Roelofsen, Peter M. van Bodegom, Lammert Kooistra, Jan-Philip M. Witte

Publikováno v: Remote Sensing, Vol 5, Iss 12, Pp 6323-6345 (2013)

Estimating plant traits in herbaceous plant assemblages from spectral reflectance data requires aggregation of small scale trait variations to a canopy mean value that is ecologically meaningful and corresponds to the trait content that affects the c

Whole-tree rainfall interception measured directly by gravimetry and its relationship with plant traits

Autor: Stefanie Pflug, Jan-Philip M. Witte, Bernard R. Voortman

Rainfall interception by vegetation is influenced by rainfall characteristics, plant traits such as crown architecture and leaf area index, and the interaction between them. We determined the cumulative seasonal interception, interception loss (inter

The salt route through time and space: Following horizontal and lateral intrusion of brackish surface water into a natural floating root mat and its plant community

Autor: Jan-Philip M. Witte, Rien Aerts, Milou Huizinga, Richard S. P. van Logtestijn, Sjoerd E. A. T. M. van der Zee

Salinizing surface water is a large problem worldwide. In many areas agriculture is dependent on surface water irrigation, but there is an increasing fresh water scarcity. Due to natural and anthropogenic processes the salt concentration of surface w

Publikováno v: Ecohydrology. 9:1222-1234

Floating fen ecosystems are home to several protected habitats and species. Their development and conservation require special attention regarding water management. Although they are known to be heterogeneous and partially buoyant, their root mats ar
