Objective
To examine the spatial and temporal variations in the suspended sediment load of four Canadian rivers.
The Hydrometric Stations
River | Station Name | Station Number |
---|---|---|
FRASER | Mission, BC | 08MH024 |
ANNAPOLIS | Wilmot, NS | 01DC005 |
NORTH SASKATCHEWAN | Prince Albert, SK | 05GG001 |
MACKENIZE | Arctic Red River, NWT | 10LC014 |
Instructions
Analyze and explain the variations in suspended sediment load and concentration over time and between stations. Make extensive use of graphs and tables. Start with the following analyses:
Compare sediment load and concentration among the four rivers, and discuss any differences and similarities and what they imply about the geology, geomorphology, land cover and climate of these watersheds. This discussion must focus on the data, graphs, tables and on any information that you collect about the watersheds from the library, map library and Internet .
Here are some Web sites:
The data are stored in text (ASCII) files. The file name is the
station number. The file extension refers to the sediment or
stream flow parameter:
.fsm | > | summary of flow data, mean monthly values for the period of record |
.fdy | > | the daily discharge data |
.fex | > | extreme discharges |
.fmn | > | mean flows, mean monthly values for each year |
.ssm | > | summary of sediment data |
.cdy | > | the daily sediment concentration data |
.ldy | > | the daily sediment load data |
For example, the file 08MH024.cdy contains the daily sediment concentrations for the Fraser River measured at Mission, B.C.. The data are in tables (i.e., space delimited), so you should be able to load them directly into a spreadsheet.
