Summary
Abstract:
The Branch-Network Dynamic Flow Model (BRANCH) is used to simulate steady or
unsteady flow in a single open-channel reach (branch) or throughout a system of
branches (network) connected in a dendritic or looped pattern. BRANCH is
applicable to a wide range of hydrologic situations wherein flow and transport
are governed by time-dependent forcing functions. BRANCH is particularly
suitable for simulation of flow in complex geometric configurations involving
regular or irregular cross sections of channels having multiple
interconnections, but can be easily used to simulate flow in a single, uniform
open-channel reach. Time-varying water levels, flow discharges, velocities,
and volumes can be computed at any location within the open-channel network.
Stream flow routing and computation by the BRANCH model is superior to
simplified-routing methods in open-channel reaches wherein severe backwater and
(or) dynamic flow conditions prevail. Typical uses of the model encompass the
assessment of flow and transport in upland rivers in which flows are highly
regulated or backwater effects are evident, or in coastal networks of open
channels wherein flow and transport are governed by the interaction of
freshwater inflows, tidal action, and meteorological conditions. Surface- and
ground-water interactions can be simulated by the coupled BRANCH and USGS
modular, three- dimensional, finite-difference ground-water flow (MODFLOW)
models, referred to as MODBRNCH.
