hydrologic cycle evapotranspiration gross primary productivity entropy production soil water retention
2015/2/3
The synergy between the hydrologic extremes, plant transpiration, gross primary productivity, and soil water retention was studied in the experimental area Zábrod – Meadow in the Šumava Mts. (Boh...
Preparation, Swelling and Water-retention Properties of Crosslinked Superabsorbent Hydrogels Based on Guar Gum
Superabsorbent hydrogel Guar gum Sodium acrylate Water absorption Water retention
2011/12/13
Utilization of natural polymer as matrix for preparing hydrogels can improve the performance of the materials and render them environmentally friendly. In this work, the guar gum-g-poly(sodium acrylat...
Contaminant transport to public water supply wells via flood water retention areas
Contaminant transport public water supply wells flood water retention areas
2009/12/8
The essential processes and mechanisms of the transport of contaminants from a river to a well field via a flood water retention area are presented. The transport is conceptualized as a succession of ...
Preferential Flow and Melt Water Retention in Cold Snow Packs in West-Greenland
Preferential Flow Melt Water Retention Cold Snow Packs West-Greenland
2009/10/23
Runoff from seasonal snow covers in Greenland provides the major source of
stream flow in the non-glacierized catchments, and has gained interest in relation
to hydropower potentials and water suppl...
An alternative deterministic method for the spatial interpolation of water retention parameters
spatial interpolation water retention parameters
2009/4/28
There are two approaches available for mapping water retention parameters over the study area using a spatial interpolation method. (1) Retention models can be first fitted to retention curves availab...
Direct measurement of the soil water retention curve using X-ray absorption
X-ray absorption soil hydraulic properties soil water dynamics Richards’equation
2009/3/3
X-ray absorption measurements have been explored as a fast experimental approach to determine soil hydraulic properties and to study rapid dynamic processes. As examples, the pressure-saturation relat...
Identification and model based assessment of the potential water retention caused by land-use changes
the potential water retention land-use changes
2010/1/27
The extreme summer flood in the Elbe River watershed initiated a debate on the role of forest conversion and afforestation as measures for preventive flood protection. To quantify the effect of forest...
Water Retention by Colloidal Allophane and Imogolite with Different Charges
Allophane Imogolite Net Charge pH Pressure Potential Water Retention
2011/12/8
Abstract: Water retention curves of colloidal allophane and imogolite with different charges and different pretreatments were measured using a tension plate and a pressure plate apparatus. An irrevers...
