Brackel, A.K.C. (author)Brackish waters can be found in transition zones between freshwater rivers and saltier seas. These dynamic coastal landscapes harbor multiple functions such as housing, agriculture, nature, and industry. Because of climate change, existing borders between fresh and saline water - and between land and water - are becoming contested. Extreme...doctoral thesis 2024

Pletzer, Johannes (author)At speeds roughly between five and ten thousand km/h, hypersonic aircraft offer the promise of an extremely fast means of transport. Growing concerns about climate warming, however, direct attention to sustainability. This thesis focuses on atmospheric composition and radiation changes by considering a range of individual hypersonic aircraft...doctoral thesis 2024

Annor, F.O. (author)The importance of small reservoirs for the livelihoods of people in the Upper East Region of Ghana cannot be over-emphasized. They are used for many purposes which include fishing, livestock watering, construction, irrigation, recreation, drinking water, and other domestic uses. The reservoirs were built most often close to communities to...doctoral thesis 2023

Tang, Yuchen (author)Rivers are vital for maintaining freshwater ecosystems as they distribute nutrients as well as dilute and transport anthropogenic pollution. Tracers provide direct empirical data on complex waterflows and reveal transport processes of waterborne substances. Recent advances in material engineering and biomolecular technology have made it possible...doctoral thesis 2023

Belloni, C. (author)This thesis focuses on recycling resources while preserving water quality and availability. This concept is at the basis of a healthy and sustainable society yet works needs to be done. Water scarcity will be a growing challenge that humanity will have to face in the coming years, due to poor resource management and the climate change crisis....doctoral thesis 2023

Zimba, H.M. (author)Through precipitation retention and evaporation (by both interception and transpiration), woodlands play a significant role in the global moisture cycle. Evaporation is the largest, but at the same time, the most difficult flux to observe in a woodland. Accounting for woodland evaporation is important for hydrological modelling for the efficient...doctoral thesis 2023

Eisfeld, R.C.M. (author)Fresh water is an essential resource for life. Yet, overexploitation of water resources, rainfall shortages, and a decrease in water quality by pollution increase water scarcity worldwide. Since agricultural production consumes about 70% of the available fresh water resources, it is particularly vulnerable for water scarcity. Therefore, this...doctoral thesis 2023

Romanos, C. (author)The role played by the Mekong River in the organization of land and people is inextricably linked with a particular spatial category. The concept of the hydrological catchment extends the space of the river far beyond the limits of the river’s perennial waterbodies, to encompass vast areas inhabited by millions of people speaking different...doctoral thesis 2023

Venugopal, A. (author)Climate change, due to the continued emissions of carbon dioxide into our atmosphere and subsequent warming of the planet, is an existential crisis facing humanity. The rising temperature is are resulting in the melting of our ice caps and glaciers, influencing the weather patterns, are making many parts of the world unliveable and are driving...doctoral thesis 2023

Nagtegaal, M.A. (author)Magnetic Resonance Imaging (MRI) is a flexible medical imaging technique that facilitates measurement of a wide range of contrasts particularly in soft tissue (e.g. brain and heart). Conventionally, qualitative images are acquired in which certain physical tissue properties are emphasized such as the transverse and longitudinal relaxation times....doctoral thesis 2023

Chen, B. (author)In recent years, considerable attention has been given to the utilization of municipal solid waste incineration (MSWI) bottom ash as a mineral resource for construction materials. MSWI bottom ash is the primary residue discharged after incinerating municipal solid waste. The generation of MSWI bottom ash is increasing dramatically with the wide...doctoral thesis 2023

Ariëns, M.I. (author)Hydrogen gas is an essential reagent in numerous industrial processes including ammonia synthesis. Ammonia is a key intermediate in the synthesis of nitrogen-based fertilisers, e.g. nitrates and urea. According to recent estimates (2008), approximately half of the world population is fed by nitrogen-based fertilisers of synthetic origin....doctoral thesis 2023

Vermunt, P.C. (author)Observing vegetation water dynamics from space offers insights into plant-water relations and water and carbon fluxes across ecosystems at local to global scales. A promising technique to observe water in the vegetation layer is radar, an active form of microwave remote sensing. Interactions between microwaves and vegetation material depend on...doctoral thesis 2022

Wang, Q. (author)To eliminate organic micropollutants (OMPs) from (surface) water, activated carbon adsorption is a cost-effective technology to remove a broad range of OMPs without producing any byproducts. However, co-existing dissolved organic matter (DOM), at much higher concentrations (mg C/L) than OMPs (ng/L-μg/L), inducing adsorption competition, can...doctoral thesis 2022

Li, K. (author)Naturally fractured reservoirs (NFRs) gain much attention worldwide because they are often encountered in aquifer remediation, CO2 sequestration, and hydrocarbon extraction. In hydrocarbon extraction, however, oil recovery by gas injection in NFRs is usually low, because of poor sweep efficiency. During gas injection, the displacement front is...doctoral thesis 2022
