Question

Determine the outflow hydrograph given the inflow hydrograph below. Use Musk- ingum routing, taking K = 2 hr, x = 0.2, and At = 1 day. From the inflow and outflow re- lation computed, investigate the effects of different values of x, x = 0, 1 and 0.5, and graph weighted discharge vs. storage. (See Example 4.4.) TIME (hr) INFLOW (m/s) 100 140 200 320 400 560 750 700

Answer 1

from a known hydrograph upstream; as the hydrograph moves. hydrograph at a place on a watershed.

How is hydrological outflow determined?

• The relationships listed below serve as definitions for it.
• A hydrograph is a tool for tracking changes in water level over time. Stage and streamflow may be shown on a hydrograph graphic, or even both.
• The visual display of water level data and forecasts on a single graphic is made possible by the use of hydrographs.
• when the hydrograph travels upstream from a known hydrograph. location of a hydrograph on a watershed.
• Mass intake minus Mass outflow equals a change in mass storage.
• Volume Outflow minus Volume Inflow is a change in storage.
• P+I+(R+G+E+T)=S, and P-(R+G+E+T)=S.
• Rainfall-Runoff equals evaporation.
• Writing the water balance equation, we get:... = 2.15 m3/s using the water budget equation.
