What Is Hydro Excavation?

Hydraulic model is a small-scale model made in the laboratory to simulate the dynamic changes of water in the complex natural environment, that is, the diffusion process of substances in water. It is used to predict the changes that will occur when the environment exerts some influence at that time. The horizontal and depth ratios are different and designed according to similar laws. According to the purpose of the experiment, the factors that dominate the various phenomena and changes can be determined and the pollutant diffusion law and situation in the model (such as the designed river, lake, bay, etc.) can be observed.

It is used to predict the changes that will occur when the environment exerts some influence at that time. The horizontal and depth ratios are different and designed according to similar laws. According to the purpose of the experiment, the factors that govern the combination of various phenomena and changes can be determined and the diffusion law and situation of pollutants in the model (such as the designed river, lake, and bay models) can be observed ^.

As a water company, the data of the pipe network is available, but how can it be operated to ensure both the demand for water supply and reduce energy consumption and leakage? How can we predict the possible burst of pipes based on the existing pipe network? Scope? Pollutant tracking? How to choose the best one from many emergency plans when an emergency occurs?

How to know if the expansion and reconstruction of the pipeline network is reasonable in design? ... To achieve this, we need to analyze the existing data of the Water Division. So much data is analyzed by the human brain, both in terms of accuracy and efficiency It was unreliable, so a hydraulic model that relied on a computer for analysis and simulation appeared.

According to the terms of reference, the model work required by the Advisory Expert Group includes:

1. Development and establishment of a hydraulic model-The model is needed to review, analyze and evaluate the city's flood control measures and make recommendations for optimal design.

2. Development can establish a water quality model-This model needs to be used to review and evaluate the advantages and disadvantages of urban water environment improvement engineering measures, and to make recommendations for optimal design.

3. Participate in the integration of plans and strategies in water resources management.

4. Train technical staff of project office and project implementation unit ^[1] .
