Roy, N. (author)Interactive information retrieval (IIR) is a user-centered approach to information seeking and retrieval. In this paradigm, the search process is not confined to a single query and a static set of results. Instead, it emphasises the active involvement of users in refining their information needs, iteratively modifying queries, and exploring...doctoral thesis 2024

Lakerveld, Stijn (author)Salt Marshes are a coastal ecosystem which have numerous benefits as coastal defense such as wave attenuation and can adapt to sea level rise. Wave flume tests, using a scale model of a cross-section of a salt marsh adjacent to a dike, were conducted in the Hydraulic Laboratory, to quantify the effectiveness of such a salt marsh system as flood...master thesis 2024
