  • Basic overview towards the assessment of landslide and subsidence risks along a geothermal pipeline network

    • Authors: Westen, C.V.; Astisiasari;  Advisor: -;  Participants: - (2018)

  • This paper aims to give a basic overview on the existing approaches for the assessment of multi-risk assessment along geothermal pipelines. It delivers basic principles on the analysis of risks and its contributing variables, in order to model the loss consequences. By considering the loss consequences, as well as the alternatives for mitigation measures, the environmental safety in geothermal working area could be enforced.

  • Climate-Determined Suitability of the Water Saving Technology "Alternate Wetting and Drying" in Rice Systems :A Scalable Methodology demonstrated for a Province in the Philippines

    • Authors: Nelson, Andrew;  Advisor: -;  Participants: - (2015)

  • 70% of the world’s freshwater is used for irrigated agriculture and demand is expected to increase to meet future food security requirements. In Asia, rice accounts for the largest proportion of irrigated water use and reducing or conserving water in rice systems has been a long standing goal in agricultural research. The Alternate Wetting and Drying (AWD) technique has been developed to reduce water use by up to 30% compared to the continuously flooded conditions typically found in rice systems, while not impacting yield. AWD also reduces methane emissions produced by anaerobic archae and hence has applications for reducing water use and greenhouse gas emissions. Although AWD is being promoted across Asia, there have been no attempts to estimate the suitable area for this promising...

  • CoastColour Round Robin data set :a database to evaluate the performance of algorithms for the retrieval of water quality parameters in coastal waters

    • Authors: Nechad, B;  Advisor: -;  Participants: - (2015)

  • The use of in situ measurements is essential in the validation and evaluation of the algorithms that provide coastal water quality data products from ocean colour satellite remote sensing. Over the past decade, various types of ocean colour algorithms have been developed to deal with the optical complexity of coastal waters. Yet there is a lack of a comprehensive intercomparison due to the availability of quality checked in situ databases. The CoastColour Round Robin (CCRR) project, funded by the European Space Agency (ESA), was designed to bring together three reference data sets using these to test algorithms and to assess their accuracy for retrieving water quality parameters. This paper provides a detailed description of these reference data sets, which include the Medium Resolu...

  • Coastal changes and movements in the wider Vlora (Albania) area

    • Authors: Kanjir, U.;  Advisor: -;  Participants: - (2016)

  • This paper explores the environmental change monitoring on the Albanian coastline (Vlora area) by analysing optical remote sensing data. Changes along this coastline are driven by coastal erosion and abusive urban construction of mostly tourist complexes and other man-made processes and pressures (e.g. sandpits, poor wastewater management, etc.). The change detection is based on yearly Landsat data of the period between 1984 and 2015. On the basis of mentioned images, each year's Normalized Difference Water Index (NDWI), Normalized Difference Build-up Index (NDBI) and Normalized Difference Vegetation Index (NDVI) are extracted. With the use of change vector analysis technique the combination of these indexes were then compared between each other. The quantitative extent of coastal c...

  • Clustering-based approaches to the exploration of spatio-temporal data

    • Authors: Zurita-Milla, R.; Wu, X.;  Advisor: -;  Participants: - (2017)

  • As one spatio-temporal data mining task, clustering helps the exploration of patterns in the data by grouping similar elements together. However, previous studies on spatial or temporal clustering are incapable of analysing complex patterns in spatio-temporal data. For instance, concurrent spatio-temporal patterns in 2D or 3D datasets. In this study we present two clustering algorithms for complex pattern analysis: (1) the Bregman block average co-clustering algorithm with I-divergence (BBAC_I) which enables the concurrent analysis of spatio-temporal patterns in 2D data matrix, and (2) the Bregman cube average tri-clustering algorithm with I-divergence (BCAT_I) which enables the complete partitional analysis in 3D data cube. Here the use of the two clustering algorithms is illustrat...

  • Combined impacts of future land-use and climate stressors on water resources and quality in groundwater and surface waterbodies of the upper Thames river basin, UK

    • Authors: Hutchins, M.G.; Hutchins, M.G.;  Advisor: -;  Participants: - (2018)

  • Changes to river flows, water temperature, river and reservoir quality were predicted under three contrasting future “storylines”; one an extension of present day rates of economic development, the others representing more extreme and less sustainable visions. Modelling revealed that lower baseflow conditions will arise under all storylines. For the less extreme storyline river water quality is likely to deteriorate but reservoir quality will improve slightly. The two more extreme futures could not be supported by current management strategies to meet water demand. To satisfy these scenarios, transfer of river water from outside the Thames river basin would be necessary. Consequently, some improvement over present day water quality in the river may be seen, and for most indicators c...

  • Climate change, uncertainty, and consequent risks :Opportunities for forest management adaptation in Britain

    • Authors: van der Veen, A.; Petr, M.;  Advisor: -;  Participants: - (2014)

  • Thesis explore uncertainty from a decision maker’s perspective; investigate uncertainty from a modeller’s perspective ;reports on the outputs from the drought risk assessment across Britain for the three major species and provides a better understanding of quantified climate change uncertainty; highlights changes of the main forest ecosystem goods and services under climate change impacts over the next 80 years, and suggests how they can be incorporated within the dynamic adaptive policy pathways approach modified for forestry application; reports on changes in forest planners’ decisions about expiry dates for forestry management actions due to new climate change information and discuss the barriers for uptake of this information in the forest planning; reflects on the key findings,...

  • Climate change impacts on future snow, ice and rain runoff in a Swiss mountain catchment using multi-dataset calibration

    • Authors: Addor, N.; Etterm, S.;  Advisor: -;  Participants: - (2017)

  • Water resources in the Alps are projected to undergo substantial changes in the coming decades. It is therefore essential to explore climate change impacts in catchments with hydropower facilities. We found that the annual runoff dynamics will undergo significant changes with more runoff in winter and less in summer by shifting parts of the summer melt runoff to an earlier peak in spring. We furthermore found that the MDC reduces the uncertainty in the projections of glacial runoff and leads to a different distribution of runoff throughout the year than if calibrated to discharge only. We therefore argue that MDC leads to more consistent model results by representing the runoff generation processes more realistically.

  • Climate change and water resources: Case study of Eastern Monsoon Region of China

    • Authors: Duan, Q.; Xia, J.;  Advisor: -;  Participants: - (2017)

  • This paper addresses the impact of climate change on the water cycle and resource changes in the Eastern Monsoon Region of China (EMRC). It also represents a summary of the achievements made by the National Key Basic Research and Development Program (2010CB428400), where the major research focuses are detection and attribution, extreme floods and droughts, and adaptation of water resources management. Therefore, climate change is making a significant impact and will be a risk to the EMRC, which covers almost all of the eight major river basins, such as the Yangtze River, Yellow River, Huaihe River, Haihe River, and Pearl River, and to the South-to-North Water Diversion Project (middle line). To ensure water security, it is urgently necessary to take adaptive countermeasures and redu...
