Muskingum Flood Routing Studio Module

MC-X Module: Muskingum-Cunge Cross-Section Routing

This clean MC-X module uses user-provided channel geometry to build a rating curve, estimate wave celerity from dQ/dA, calculate Muskingum-Cunge K and X, route the hydrograph, and save results separately from MC-E.

MC-X method rebuilt from geometry.

MC-X is now separate from MC-E. It requires channel geometry such as bottom width, top width, and maximum flow depth. The software builds a hydraulic rating curve and calculates celerity from the local slope of that curve.

MC-X Input

Project Information

Reach and Routing Data

Use decimal slope. 0.007 means 0.7%.
Leave empty unless you want to force Qb.
Leave empty unless you want to force Qp.
If unchecked, MC-X will ignore the common lateral inflow and route only the main inflow hydrograph.

MC-X Channel Geometry

Thesis MC-X ratio: Wmax / ymax
For thesis MC-X parabolic geometry: Wi = (Wmax/ymax)yi, A = 2yW/3, P = W + 8y²/(3W), R = A/P.

Common Workspace Hydrograph

MC-X does not create separate hydrological data. It loads the common workspace hydrograph and uses only the geometry entered in this MC-X panel.
MC-X thesis methodology used in this module
Wi = (Wmax / ymax) × yi
Ai = 2yiWi / 3
Pi = Wi + 8yi2 / (3Wi)
Ri = Ai / Pi
Qi = (1/n) Ai Ri2/3 S1/2
Vw = (11/9) × Vav
K = ΔL / Vw
X = 0.5 − Q0 / (2 S W0 Vw ΔL)
Oi = C0Ii + C1Ii−1 + C2Oi−1
