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 1Data 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
  PROJECTIONUTM-1927 ZONE 12

Step 3Delineate 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 4Develop the Relation Between Precipitation
and Elevationp0.7239z-495.28
10
Step 5Get 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 6Get the Mean Annual Runoff for Each
Subwatershed

• MEAN ANNUAL RUNOFFMEAN ANNUAL STREAMFLOW OF EACH
  GAGE STATION/(DAINAGE AREA)

12
Step 7Develop 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 Runoff0.2796 Mean Annual
  Precipitation-100.21 (unitmm)
• Ongoing WorkFind the Event Mean Concentration
  For Different Land Use,Use the Formula Mean
  Annual Total Contaminant Load Mean Annual
  RunoffEvent Mean Concentration
