Advancements in Information Entropy-Based Hydrological Processes.

Session ID#: 162241

Session Description:
Velocity distribution plays an important role in understanding the hydrodynamics of open channel flows. The channel discharge, shear distribution, scouring around the bridge piers, sediment transport and erosion, and pollutant transport and its fate are dependent on the velocity distribution characteristics. Among many other approaches, the entropy-based approach holds great promise in achieving a reasonable characterization of the velocity distribution. Chiu (1987) employed the Information entropy (or Shannon entropy) in the field of water resources and developed the first entropy-based velocity distribution using the Principle of Maximum Entropy (POME). With time, other types of entropy measures, such as Tsallis entropy and Renyi entropy, have been explored to overcome the drawbacks of earlier approaches.

We are soliciting abstracts that employ Information Entropy-based approaches to study the hydrological processes (e.g., velocity distribution, suspended sediment concentration, shear stress distribution, bathymetric profile and channel discharge estimation) and support the development of novel applications (e.g., new theoretical, experimental, and computational advancements). The session focuses on (but is not limited to) exploring the comparative studies between the entropy-based approaches and other traditional ones.
