bdschism.ccf_gate_height.gen_gate_height(export_ts, priority, max_height, oh4_level, cvp_ts, inside_level0, s1, s2, dt)

Estimate Clifton Court Forebay Gate opening height.

This function estimates the opening height of the Clifton Court Forebay (CCFB) radial gates based on SWP export, eligible intervals for opening and priority level, maximum gate height allowed, OH4 stage level, CVP pump rate, and other operational rules for a given period.

Gate Opening Conditions

• Priority Eligibility: The gate opens only if priority eligibility criteria are met.

• Water Level Difference: The gate opens if the water level outside the forebay is higher than the water level inside.

Early Gate Closure

The gate will close early if the volume of water above the 2 ft contour is sufficient to cover the remaining water allocation for the day. This simulates field operations where operators aim to maintain water elevation as close to 2 ft as possible.

Gate Remains Open

The gate will remain open if the volume of water above the 2 ft contour is insufficient to cover the daily allocation, preventing the water level inside the forebay from dropping too low.

Gate Height Calculation

• The default gate height is 16 ft, but a maximum height based on export level is applied.

• The height is adjusted to prevent flow from exceeding 12,000 cfs, reflecting operational constraints.

• The gate height is calculated using a simplified version of the flow rating equation:

  Gate Height = 11 × (Head)^-0.3 - 0.5

  where Head = Water level upstream - Water level in the reservoir.

bdschism.settings module

bdschism.settings.create_link(source, symlink, config_log=False)

Create a link between a source file and a target path based on system-specific link styles.

This function creates a symbolic link, junction, or copies the file, depending on the system settings. The link style is determined dynamically from get_settings(), which specifies the preferred linking method for the operating system.

Parameters:

• source (str) – The path to the source file that will be linked.

• symlink (str) – The target path where the link (or copy) will be created.

• config_log (bool, optional) – If True, log the configuration source being used.

Raises:

ValueError – If the link style retrieved from get_settings() is unsupported.

Notes

• If a symbolic link already exists at symlink, it is removed before creating a new one.

• On Windows, the function supports creating junction links (mklink), symbolic links, or copying the file instead.

• On Unix-based systems, it defaults to using symbolic links.

Examples

Create a symbolic link on Unix-like systems or an appropriate alternative on Windows:

>>> create_link("/path/to/source.txt", "/path/to/symlink.txt")

bdschism.settings.get_settings(config_log: bool = False)

Load and return application settings from a configuration file.

This function retrieves configuration settings using a hierarchy of possible sources: 1. A package-level default configuration file (bds_config.yaml within the package). 2. A project-level configuration file (bds_config.yaml in the current working directory). 3. An environment-specific configuration file, if BDS_CONFIG is set and points to a valid file.

The function uses Dynaconf to load settings, ensuring that the highest-priority configuration (environment variable, project-level, or package default) is used.

Returns:

A Dynaconf object containing the loaded configuration settings.

Return type:

Dynaconf

Notes

• The package-level configuration file provides default settings.

• If a project-level configuration file exists in the current directory, it overrides the package default.

• If an environment variable BDS_CONFIG is set and points to a valid file, it takes the highest precedence.

• The function logs the configuration source being used.

Examples

Load settings from the highest-priority available configuration file:

>>> settings = get_settings()
Using configuration from: /path/to/highest-priority-config.yaml current env development

Access settings:

>>> settings.some_setting
'some_value'

It search along x2 stations to find two neiboring stations higher and lower than X2 criteria (bottom or surface). If X2 retreat less than the minimum stations along the transect, the X2 result will be truncated at that point.

usage: –start 2004-04-18 –x2route x2route.bp output: x2 on surface and bottom location time series in csv format, bottom_x2.csv and surface_x2.csv
