1D Culverts

Page Under Construction

Introduction

• Advice on SX connections & number of cells to connect to 2D domain – implications
• Flow regimes – theory behind each.
• How to check for the flow regime – link to check file
• How do we sub divide logic rules (operational culverts)*
• Losses – fixed, Englehund, automatic manholes etc.
• Provide some justification on the ‘default’ height/width, entry/exit losses.

Flow Regimes

Regime / suffix	Description
A	Contains the inverts of the 1D nodes and at the ends of the 1D channels. Very useful for checking for smooth transitions from one channel to another and with the nodes.
B	Tabular data as read from tables via the 1d_tab layers for cross-section, storage and other data. Provides full traceability to original data source and additional information such as hydraulic properties determined from a cross-section profile. Flood Modeller XZ processed, and MIKE 11 processed cross-section data included. Refer also to the _xsl_check layer.
C	Contains the hydraulic properties at the top of the hydraulic properties tables as attributes of the 1D channels. Other information such as the primary Manning’s n is also provided. Very useful for carrying out quality control checks on the 1D channels.
D	Contains the inverts of the 1D nodes and at the ends of the 1D channels. Very useful for checking for smooth transitions from one channel to another and with the nodes.
E	Contains the inverts of the 1D nodes and at the ends of the 1D channels. Very useful for checking for smooth transitions from one channel to another and with the nodes.
F	Contains the inverts of the 1D nodes and at the ends of the 1D channels. Very useful for checking for smooth transitions from one channel to another and with the nodes.
G	Contains the inverts of the 1D nodes and at the ends of the 1D channels. Very useful for checking for smooth transitions from one channel to another and with the nodes.
H	Contains the inverts of the 1D nodes and at the ends of the 1D channels. Very useful for checking for smooth transitions from one channel to another and with the nodes.
J	Contains the inverts of the 1D nodes and at the ends of the 1D channels. Very useful for checking for smooth transitions from one channel to another and with the nodes.
K	Contains the inverts of the 1D nodes and at the ends of the 1D channels. Very useful for checking for smooth transitions from one channel to another and with the nodes.
L	Contains the inverts of the 1D nodes and at the ends of the 1D channels. Very useful for checking for smooth transitions from one channel to another and with the nodes.
