Tollenaar, Veronica (author)Meteorites contain information on the formation and evolution of the Solar System. Antarctica is the most productive region for collecting meteorites, as the visually contrasting meteorites are easily detectable and tend to concentrate at specific areas exposing blue ice. Blue ice areas act as meteorite stranding surfaces (MSSs) if the flow of...master thesis 2020

Hahn, Sebastian (author), Wagner, Wolfgang (author), Steele-Dunne, S.C. (author), Vreugdenhil, M. (author), Melzer, Thomas (author)This study investigates the performance of the TU Wien soil moisture retrieval (TUW-SMR) algorithm by adapting the strength of the vegetation correction.

Singh, C. (author), Wang-Erlandsson, Lan (author), Fetzer, Ingo (author), Rockström, Johan (author), van der Ent, R.J. (author)Climate change and deforestation have increased the risk of drought-induced forest-to-savanna transitions across the tropics and subtropics. However, the present understanding of forest-savanna transitions is generally focused on the influence of rainfall and fire regime changes, but does not take into account the adaptability of vegetation...journal article 2020

van Natijne, A.L. (author), Lindenbergh, R.C. (author), Bogaard, T.A. (author)Nowcasting and early warning systems for landslide hazards have been implemented mostly at the slope or catchment scale. These systems are often difficult to implement at regional scale or in remote areas. Machine Learning and satellite remote sensing products offer new opportunities for both local and regional monitoring of deep-seated...journal article 2020

Daggers, Tisja D. (author), Herman, P.M.J. (author), van der Wal, Daphne (author)Understanding the spatial structure of microphytobenthos (MPB) on intertidal flats is necessary to gain insight in the benthic community structure and ecosystem processes. The increasing availability of high resolution satellite sensors provides the opportunity to better understand spatial patterns of MPB on various (meter to km) scales. We...journal article 2020

(author), Savenije, Hubert (author), Hrachowitz, M. (author)The spatiotemporal dynamics of water volumes stored in the unsaturated root zone are a key control on the response of terrestrial hydrological systems. Robust, catchment-scale root-zone soil moisture estimates are thus critical for reliable predictions of river flow, groundwater recharge, or evaporation. Satellites provide estimates of near...journal article 2020

Simons, G.W.H. (author), Bastiaanssen, W.G.M. (author), Cheema, M.J.M. (author), Ahmad, B. (author), Immerzeel, W.W. (author)Increasing irrigation efficiencies remains the focus of numerous efforts to mitigate water scarcity. In reality, higher local efficiencies do often not reduce water scarcity, but instead cause a redistribution of water flows when the entire irrigation scheme or river basin is considered. Insufficient understanding of consumed fractions and non...journal article 2020

Chen, Yu (author), Ming, Zutao (author), Menenti, M. (author)This paper proposes a multioral image change detection algorithm based on adaptive parameter estimation, which is used to solve the problems of severe interference of coherent speckle noise and the retention of detailed information about changing regions in synthetic aperture radar remote sensing images. The change area in the initial...journal article 2020

(author), Friedman, Joshua (author)Coastal management in the Netherlands has the aim to defend coastal zones by preventing flooding and mitigating erosion. To that end, large-scale nourishments are placed in the nearshore, which are supposed to dynamically preserve the coastal zone over a timescale of years. To assess their effectiveness, these nourishments are monitored over...journal article 2020

Mashhoodi, B. (author), Stead, D. (author), van Timmeren, A. (author)It is widely accepted that land surface temperature (LST) affects household energy consumption (HEC). There is, however, no previous study available that clarifies whether LST's impact is similar in each and every area, or if it varies from one location to another. Analysing the impact of LST on HEC of 2612 residential zones of the...journal article 2020

Yet, assessing how much and how fast both glaciers will weaken if these changes continue remains a major uncertainty as many of the processes that control their...journal article 2020

Ball, W.T. (author), Chiodo, Gabriel (author), Abalos, Marta (author), Alsing, Justin (author), Stenke, Andrea (author)The stratospheric ozone layer shields surface life from harmful ultraviolet radiation. Following the Montreal Protocol ban on long-lived ozone-depleting substances (ODSs), rapid depletion of total column ozone (TCO) ceased in the late 1990s, and ozone above 32 km is now clearly recovering. However, there is still no confirmation of TCO recovery,...journal article 2020

Dooren, Mirja (author)Understanding the river dynamics is very important to be able to make use of all river functions and to protect ourselves against floods. Hydrodynamic models are used to predict river behaviour and one of the input parameters is the river geometry. In-situ measuring of river geometry can be very expensive and time consuming.

Petchiappan, Ashwini (author)The Amazon rainforest is among the most vital ecosystems on earth, holding about a quarter of the global terrestrial carbon sink. Since 2005, three 100-year return period droughts have occurred, the likes of which have the potential to turn the forest from a carbon sink to a source – meaning disastrous consequences for the planet. Monitoring of...master thesis 2019
