Name_________________Date__________________Lab Assignment 8: Discharge, Rivers, and FloodingFor this lab assignment, we will analyze river basin systems in association with their discharge rates and how flood prone they may be. PART 1: DISCHARGE RATESRiver discharge is measured Q=W*D*u. Q stands for the discharge, W stands for the width, D stands for the depth, and u stands for the velocity of the river. For each hypothetical river below, calculate thedischarge. Calculate each discharge only in seconds, unless otherwise specified. Calculations for the final result are in m3/s.1) Blue River, W=130m, D=30m, u=3.4m/s 2) Green River, W=200m, D=3m, u=5.3m/s_________________________________ ___________________________________3) Red River, W=30m, D=15m, u=1.3m/s 4) Orange River, W=340m, D=45m, u=10.4 m/s_________________________________ ____________________________________5) Black River, W=5m, D=1m, u=0.4m/s 6) Purple River, W=544m, D=65m, u=4.5m/s_________________________________ ____________________________________7) Neon River, W=10m, D=10m, u=10m/s 8) Pink River, W=35m, D=100m, u=5.5m/s_________________________________ ____________________________________9) Maroon River, W=45m, D=20m, u=2.2m/s 10) Cyan River, W=100m, D=23m, u=6.4m/s_______________________________ ____________________________________PART 2: RIVER DISCHARGES (SELECTED RIVER) For the selected rivers below list the discharge in cubic meters a second (m³/s). You can find the discharge of each selected river on Google. Then record the discharge for a minute, hour, and day. 1) Passaic River_______________ 2) Hudson River________________Minute(m³/min)_______________ Minute(m³/min)_______________ Hour(m³/hr) _________________ Hour(m³/hr) _________________ Day(m³/day) _________________ Day(m³/day) _________________3) Danube River_______________ 4) Rio Grande____________________Minute(m³/min)_______________ Minute(m³/min)_______________ Hour(m³/hr) _________________ Hour(m³/hr) _________________ Day(m³/day) _________________ Day(m³/day) _________________5) Volga River_________________ 6) Snake River_____________________Minute(m³/min)_______________ Minute(m³/min)_______________ Hour(m³/hr) _________________ Hour(m³/hr) _________________ Day(m³/day) _________________ Day(m³/day) _________________7) Ohio River__________________ 8) St. Lawrence River________________Minute(m³/min)_______________ Minute(m³/min)_______________ Hour(m³/hr) _________________ Hour(m³/hr) _________________ Day(m³/day) _________________ Day(m³/day) _________________PART 3: RIVER SOURCE LOCATIONS AND ELEVATIONSFor this part of the lab, I will list select rivers and their sources. Open up Google Earth, and look up thelatitude (bottom right corner) that is given for each. When Google Earth reaches that destination, write down the elevation of the source.1) Mississippi River, 47°14′23″N 95°12′27″W 5) Passaic River, 40°45′43″N 74°34′42″W________________________________ ____________________________2) Hudson River, 44°5′28″N 74°3′21″W 6) Missouri River, 44°32′31″N 111°27′53″W________________________________ __________________________________3) Rio Grande River, 37°47′52″N 107°32′18″W 7) St. Lawrence River, 44°06′N 76°24′W________________________________ _______________________________4) Snake River, 44°7′49″N 110°13′10″W 8) Rhine River, 46°37′57″N 8°40′20″E________________________________
