1. Effects of modified river cross-section geometry on hydraulic modelling performance: the slope break method
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Remote sensing data has been widely used for large scale hydraulic modelling in the world. One of the most common ways to collect remote sensing data is by satellite. The digital elevation data observed from space is publicly accessible and covers almost all areas of the earth. However, the satellite cannot observe the river bathymetry. LÄS MER
2. The pathway to outcompete fossilfuels : Solar thermal as an alternative for industrial heating processesin Gujarat, India
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Byggteknik och byggd miljöSammanfattning : 2015 the Paris agreement was signed to tackle the climate change and reduce emissions from fossil fuel burning. The industrial and manufacturing sector which alone accounts for 32% of global energy use relies heavily on fossil fuels. Solar thermal energy is a renewable energy source that has potential of replacing large portions of this energy. LÄS MER
3. Vegetation phenology derived using the plant phenology index and the normalized difference vegetation index for the Balkan peninsula, south-eastern Europe
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : This study analyses the performance of the satellite derived Plant Phenology Index (PPI) against the Normalized Difference Vegetation Index (NDVI) for estimating start of season (SOS) and end of season (EOS) of vegetation growth in part of the Balkan Peninsula, Southeastern Europe (2000 – 2016). Results revealed that PPI and NDVI differ considerably; SOS and EOS may diverge by more than one month between the two indices. LÄS MER
4. Application of a new method to improve river cross sections derived from satellite images
Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : In hydrological and hydraulic modelling, river geometry is a crucial input data. Recent investigations have been looking at methods to improve the description of cross sections extracted by DEM derived by satellite images. LÄS MER
5. Satellite derived data to support flood modelling : An application to the Po River
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Satellite derived data has become an essential input in hydraulic modelling. Digital ElevationModels (DEMs) derived from different sources through remote sensing techniques have become a powerful tool for poorly gauged regions. LÄS MER
