1. WATER RESEARCH OF PINEVIEW RESERVOIR
XIONGFEI LIU
12/3/99

2. Goals
TO DEVELOPE THE RELATIONSHIP BETWEEN MEAN ANNUAL RUNOFF AND PRECIPITATION IN THE PINEVIEW RESERVOIR WATERSHED
TO ESTIMATE THE TOTAL ANNUAL CONTAMINANT LOAD IN THE PINEVIEW RESERVOIR

3. Step 1:Data Collection DEM RF3
WEATHER STATION HISTORICAL PRECIPITATION
GAGE STATION HISTORICAL STREAMFLOW
LAND USE AND LAND COVER
WATER QUALITY STATION DATA
POINT CONTAMINATION SOURCES

4. Step 2: Preprocess of Raw Data
USE MICRODEM TO MERGE AND CLIP THE RETRIVED DEM DATA
USE TARDEM GAPFILL TO FILL THE GAPS IN THE DEM
CREATE GAGE STATIONS POINT THEME
CREATE CLIMATE STATIONS POINT THEME
PROJECT ALL THE THEMES IN THE SAME PROJECTION:UTM ZONE 12

6. Step 3:Delineate the Watershed and Stream Network
ADD ALL THE GAGE STATION AS ADDED OUTLETS FOR THE OUTLET THEME
USE CRWR-PREPRO TO DELINEATE THE SUB-WATERSHED AND STREAM NETWORKS
CREATE ALL THE SUBWATERSHEDS USING GAGE STATIONS AS OUTLETS

9. Step 4:Develop the Relation Between Precipitation and Elevation p=0
Step 4:Develop the Relation Between Precipitation and Elevation p=0.7239*z

10. Step 5:Get the Mean Precipitation for Each Subwatershed
USE THE PRECIPITATION VERSUS ELEVATION FUNCTION GET THE PRECIPITATION FOR THE PINEVIEW WATERSHED
MAKE MASK FOR EACH SUBWATERSHED,THEN USE MAP CALCULATOR TO GET THE PRECIPITAION FOR EACH SUBWATERSHED
GET THE MEAN PRECIPITATION FOR EACH SUBWATERSHED

11. Step 6:Get the Mean Annual Runoff for Each Subwatershed
MEAN ANNUAL RUNOFF=MEAN ANNUAL STREAMFLOW OF EACH GAGE STATION/(DAINAGE AREA)

12. Step 7:Develop the Relationship Between Mean Annual Runoff and Precipitation
COLLECT MEAN ANNUAL RUNOFF AND PRECIPITATION DATA FOR EACH SUBWATERSHED
USE MICROSOFT-EXCEL TO DEVELOP THE FUNCTION FOR MEAN ANNUAL RUNOFF AND PRECIPITATION FOR THE PINEVIEW WATERSHED

13. Conclusion ...and Ongoing Work
Conclusion:(for Pineview Reservoir Watershed)
Mean Annual Runoff=0.2796* Mean Annual Precipitation (unit:mm)
Ongoing Work:Find the Event Mean Concentration For Different Land Use,Use the Formula: Mean Annual Total Contaminant Load= Mean Annual Runoff*Event Mean Concentration
