Abstract

The DHLLDV model consists of a framework to determine the resulting hydraulic gradient curve for spatial volumetric concentrations and uniform sands, consisting of parts of five flow regimes: fixed or stationary bed transport, sliding bed transport, heterogeneous transport, homogeneous transport and sliding flow transport. Each flow regime has its own physical and mathematical model. Once the resulting hydraulic gradient curve and the limit deposit velocity are determined, a holdup function enables the user to construct the delivered volumetric concentration curve and the bed height. The authors have developed an open source software library, written in the Python programming language, that implements the model. The paper will provide an overview of the software, how to download and test it, and how to incorporate it into a variety of types of software. Developing engineering software presents a number of challenges: tracking and managing the development process, ensuring the quality and correctness of the resulting software, and incorporating the software into existing engineering processes. The software is hosted in a Git software repository, to enable a transparent and traceable development process.
