Yes, there are hydrological routing methods suitable for intermittent flow in river networks. While the Muskingum-Cunge method is based on continuous flow, the following methods can handle intermittent flows:

These methods can be adapted to better suit intermittent flow conditions along the river network.

Yes, there are several hydrological methods that can be used to route intermittent flow along a river network. The choice of the appropriate method depends on the nature of the network and the flow characteristics. Below is a structured and logical approach to selecting the right method:

1. Analyzing the Nature of Intermittent Flow

Before selecting the appropriate routing method, it is essential to determine the characteristics of the intermittent flow, including:

Flow frequency: Is it seasonal, caused by sudden rainfall, or due to human releases?

Flow volume and duration: Is it small and temporary, or large and prolonged?

Impact on the hydrological network: Does it cause sedimentation, erosion, or changes in the river path?

2. Suitable Hydrological Routing Methods

A. Traditional Hydrological Routing Methods

1. Muskingum Method (Semi-empirical Model)

Suitable for rivers with natural or semi-natural channels.

Accounts for dispersion and storage in the channel.

Requires parameters based on river characteristics (X and K).

Useful for intermittent flows resulting from short-term rainfall events.

2. Saint-Venant Method (Partial Differential Equations for Unsteady Flow)

More accurate as it is based on mass and momentum conservation laws.

Suitable for rivers with fast flow and significant variations in water levels.

Requires numerical solutions and is commonly used in hydrodynamic modeling (HEC-RAS, TELEMAC, MIKE 11).

3. Storage Routing Method

Based on balancing water storage in different river sections.

Suitable when natural or artificial storage areas influence the flow.

B. Modern Hydrological Routing Models (Data-Driven and Numerical Modeling)

1. Artificial Neural Networks (ANN) and AI-Based Models

Useful if historical flow data is available.

Uses techniques like ANN and LSTM to predict river behavior under intermittent flow conditions.

2. GIS-Based and SWAT Models

Utilize Geographic Information Systems (GIS) to analyze the impact of intermittent flows at the watershed level.

Effective for studying flash floods and their influence on the river network.

3. Selecting the Most Suitable Method Based on Conditions

Conclusion

If the intermittent flow is short-term and small in volume → Use Muskingum Method.

If the flow is unsteady but larger and affects water levels → Use Saint-Venant Method.

If there is water storage affecting the intermittent flow → Use Storage Routing Method.

If high predictive accuracy is required and sufficient data is available → Use Modern Models like ANN or SWAT.

By following this approach, you can select the most appropriate hydrological routing method based on the intermittent flow conditions in your river network.
