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

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

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

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-1927 ZONE 12

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

Step 4:Develop the Relation Between Precipitation and Elevation p=0 Step 4:Develop the Relation Between Precipitation and Elevation p=0.7239*z-495.28

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

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

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

Conclusion ...and Ongoing Work Conclusion:(for Pineview Reservoir Watershed) Mean Annual Runoff=0.2796* Mean Annual Precipitation-100.21 (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
