WHAT IS DISCHARGE? Discharge is the volume rate of water flow that is transported through a given cross-sectional area.
HOW IS DISCHARGE MEASURED? • discharge = area (Dx. W) X velocity • Measured with current meter (pic)
WHY MEASURE DISCHARGE? Discharge measurements are used for: - River Sports - Flood alerts - Drinking waste - River Health - Irrigation Considerations - hydroelectric power production - Reservoir discharges - Plus many more
DISCHARGE DATA
Discharge at Day Use Area 2007 -2016
Discharge at Below Dam Area 2007 -2017
Discharge at Old RR Bridge 2007 -2017
San Juan Snowfall (2007 -2016)
IMPLICATIONS Factors that can driver discharge include: • Weather conditions • Land use • Rainfall • Rock and soil type -Specifically, these factors can influence increased river discharge. Since river discharge volume primarily increased, these may be factors causing the increase. -The differences in the web measurements and the 2017 data may be attributed to an error in the testing
WHAT’S IT ALL MEAN? • As water flows downstream, discharge increases significantly…but why? • River gets larger, so remember the wider deep part of the river at the day use area? Imagine that multiplied
