Design Example: Creating a Hydraulic Model of a Dam Spillway

Scaled hydraulic models of dam spillways provide a practical way to replicate and study the intricate flow dynamics of these structures. Often built to a 1:15 ratio, these models allow for observing critical water behavior, such as velocity distribution, flow patterns, and energy dissipation.

Background:

The instability theory for drumlin formation models coupled subglacial processes involving ice, water, and sediment.
This theory has evolved over two decades, enabling predictions of various glacial landforms, including ribbed moraines, drumlins, and mega-scale glacial lineations.
Previous efforts to numerically solve the model have been constrained.

Purpose of the Study:

To present the current state of the drumlin formation instability theory.
To introduce a novel numerical method for solving the model.
To investigate the model's ability to simulate realistic glacial bedform evolution.

Main Methods:

Summarizing and refining the existing instability theory for drumlin formation.
Developing a new numerical approach to solve the coupled subglacial flow model.
Testing the model with realistic parameter values, focusing on the subglacial water film.

Main Results:

The refined theory incorporates updated descriptions of the subglacial water film and its flow.
The new numerical method allows for solutions with most parameters set to realistic values, except for water film thickness.
The model successfully generates three-dimensional bedforms of appropriate sizes, demonstrating sensitivity to parameter variations.

Conclusions:

The instability theory provides a robust framework for understanding drumlin formation and related glacial landforms.
The developed numerical method enhances the model's solvability for realistic glacial conditions.
Further research is needed to refine the representation of subglacial water film thickness for even more accurate simulations.
