1. Höjddata i översvämningsmodellering : En fallstudie om hur höjdmodellens upplösning kan förbättra precisionen hos den 1D/2D-kopplade hydrauliska modellen LISFLOOD-FP
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Syftet med fallstudien var att undersöka möjligheterna och nyttan med att implementera en höjdmodell med högre upplösning i SMHI:s översvämningsmodellering som tillämpar den hydrauliska modellen LISFLOOD-FP. SMHI utfärdar översvämningsvarningar och det är därför av vikt att översvämningsmodelleringen håller hög kvalitet. LÄS MER
2. Behind the early warning: Improving impact-based forecasting of riverine floods in Malawi using passive microwave remote sensing
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : This thesis investigates whether freely available, coarse-resolution, Passive Microwave Remote Sensing (PMRS) data (37 GHz) can be effectively used for early warning systems for floods in Malawi. The Shire River Basin in Chikwawa and the smaller-scale North Rukuru River Basin in Karonga were studied using two alternative, ratio-based satellite indices that make use of the signal difference between wet and dry pixel cells: The m index and the rcmc index.

3. Prioritising biochar application to arable land in Sweden : A spatial multi-criteria analysis
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Biochar, the solid product of thermal conversion of biomass with little or no available air, is acknowledged as a carbon dioxide removal technique and soil enhancer among other applications. Its potential soil enhancing properties consists of increased water and nutrient holding capacities, liming effects and sorption of pollutants. LÄS MER
4. Time series analysis for spring barley phenology monitoring using Sentinel 2 – A case study of Southern-central Sweden
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Monitoring crop phenology at parcel scale aligns with the concept of precision agriculture (PA) and can provide invaluable information to agronomic management systems. Satellite time series data are commonly deployed for detecting crop growth stages, while the recent advancements in remote sensing (RS) technologies such as the launch of Sentinel 2 (S2) are providing unprecedented opportunities for crop monitoring.

5. Spatial resolution threshold in layers and red jungle fowls : are there differences due to light intensity or light spectra?
Master-uppsats, SLU/Dept. of Animal Environment and HealthSammanfattning : The domestic fowl (Gallus gallus domesticus) originates from the forests in South-east Asia. It may be correct to assume that the visual system of the domestic fowl is still adapted to light that is filtered through the green forest canopy. LÄS MER
