Gautam, K. (author), Wolf, M.E. (author), Bogaard, T.A. (author), Blom, A. (author)The dynamics of the bifurcating Karnali river in the western plains of Nepal and India is governed by the geomorphological processes in an alluvial fan. The dynamic branches showcase a notable degree of braiding, dominant channel switching and unequal discharge partitioning. Since recent switching of the dominant channel of Karnali system...abstract 2024

Li, K. (author), Wolf, K.H.A.A. (author), Rossen, W.R. (author)Foam is applied in enhanced oil recovery to improve the sweep of injected gas and increase oil recovery, by greatly reducing the mobility of gas. In the laboratory, X-ray computed tomography is commonly used to evaluate the performance of foam in core plugs. However, foam properties, such as bubble size and capillary pressure, are much more...journal article 2022
