Quantitative characterization of solute transport processes in an undisturbed unsaturated soil by means of electrical resistivity tomography (ERT)
(2010-07-27)
Improved understanding of water flow and solute transport through the unsaturated zone is important for the sustainable management of soils. As soils are complex and heterogeneous systems, quantification of the transport ...
Effects on the Geodetic-VLBI Observables Due to Polarization Leakage in the Receivers
(2010-07-01)
Geodetic VLBI delivers baseline length and Earth orientation parameter measurements, which offer the most viable and precise way to study Earth crustal and core dynamics and to support space navigation. The precision of ...
Hydrological Characterization of a Forest Soil Using Electrical Resistivity Tomography
(2010-07-13)
An explicit knowledge of soil properties is required in agronomy, nature conservation, and hydrology to characterize water storage and water flow processes, even more in the context of climate change. Electrical resistivity ...
Assessing People´s Early Warning Response Capability to Inform Urban Planning Interventions to Reduce Vulnerability to Tsunamis: Case Study of Padang City, Indonesia
(2014-03-10)
In the last decade, more emphasis is given on the human aspect of early warning or the attribute of “people-centered” early warning systems. This study seeks to better understand the specific conditions that shape people´s ...
Retrieval of Sea Level and Surface Loading Variations from Geodetic Observations and Model Simulations: an Integrated Approach
(2014-04-07)
The mass distribution in the system Earth changes dynamically over time. Time-variable mass transport mainly arises from the interplay between the terrestrial hydrological water cycle, the ocean and atmosphere, and the ...
Statistical Signal Decomposition Techniques for Analyzing Time-Variable Satellite Gravimetry Data
(2014-09-29)
The time-variable gravity fields from the Gravity Recovery and Climate Experiment (GRACE) satellite mission provide valuable information about total water storage variations on a global scale. This quantity is difficult ...
Socio-environmental impacts of settlement growth under conditions of fostered infill development: a methodological framework for a multicriteria assessment
(2010-09-07)
The major objective of this study is to analyze socio-environmental conditions under which a sustainable and resource-preserving settlement development can be promoted and to assess respective impacts of greenfield and ...
Konzept zur Harmonisierung und Präsentation von Nutzungsdaten auf Grundlage des 3A-Modells
(2010-06-04)
Mit dem AFIS®-ALKIS®-ATKIS®-Anwendungsschema hat die AdV ein modernes Konzept zur integrierten Führung der Geobasisdaten des amtlichen Vermessungswesens geschaffen. Die verschiedenen Grunddatenbestände des Liegenschaftskatasters, ...
Zur Entwicklung und Bewertung der absoluten GNSS-Antennenkalibrierung im HF-Labor
(2010-07-09)
Bei der relativen Positionsbestimmung mit GNSS-Verfahren stellen die Antenneneinflüsse, die sich durch eine richtungsabhängige Empfangscharakteristik auszeichnen, einen der die Genauigkeit begrenzenden Faktoren dar. Durch ...
Non-invasive monitoring of water and solute fluxes in a cropped soil
(2010-12-15)
Although the influence of root water uptake on solute transport is commonly recognized as important, it has barely been studied throughout the literature. However, plants take up a big amount of the infiltrating water and ...
