Channel Hydraulics

Channel Hydraulics#
Channel hydraulics, within the context of the Storm Water Management Model (SWMM), involves the analysis of flow and water movement through open channels such as rivers, streams, or stormwater conduits. SWMM employs hydraulic principles to simulate and predict the behavior of these channels, aiding in the assessment of stormwater runoff and the design of effective drainage systems.
Normal (Uniform) Flow#
Normal flow hydraulics in the Storm Water Management Model (SWMM) refer to the steady-state conditions of water flow within a conveyance system, typically associated with continuous, non-storm events. SWMM utilizes normal flow hydraulics to analyze and simulate the regular, base flow patterns, providing insights into the system’s capacity and performance under typical flow conditions.

Kinematic Wave#
In the context of the Storm Water Management Model (SWMM), the kinematic wave represents a simplified approach to simulate overland flow, focusing on the movement of water without considering pressure variations. This method in SWMM helps analyze the progression of surface water during storm events, providing insights into flow velocities and routing for efficient stormwater management.

Dynamic Wave#
Dynamic wave routing in the Storm Water Management Model (SWMM) involves a detailed simulation of unsteady flow conditions, accounting for variations in water depth, velocity, and pressure throughout the conveyance system. This approach in SWMM enables a comprehensive analysis of transient events, such as rainfall runoff, allowing for a more accurate representation of the dynamic behavior of water flow within the drainage network.
