  1. MODELING SOIL EROSION RIO PANUCO BASIN, MEXICO Augustine Avwunudiogba Department of Geography

  2. PRESENTATION OUTLINE • Background/Motivation • Goals of Study • Data Collection • Data Analysis • Result • Conclusion & Future Research

  3. Locator Map Rio PanucoBasin THE RIO PAUCO BASIN, MEXICO

  4. CULTIVATION IN THE UPLANDS OF RIO MOCTEZUMA WATERSHED IN THE PANUCO BASIN P.F Hudson

  5. RIO MOCTEZUMA HIGH SUSPENDED SEDIMENT LOAD HIGH SEDIMENT LOAD RELATED TO LANDUSE?

  6. GOAL/OBJECTIVES • Preliminary study • Determine the available Public Domain Data • Determine the Suitability of the Public Domain Data • Review Existing Soil Erosion Model • Conduct a preliminary Soil Erosion Assessment for the Basin

  7. USLE/RUSLE (Universal Soil Loss Equation) – Wischmeier & Smith, 1978/Renard et al.,1987 WEPP (Water Erosion Prediction Project)-Nearing et al.,1989 EUROSEM (European Soil Erosion Model)-Morgan et al.,1991 EPIC (Erosion Productivity Impact Calculator)-Williams et al.,1984 CREAMS(Chemical Runoff and Erosion from Agricultural Management Systems)-Knisel,1980 KINEROS (Kinematic Erosion Simulation Model)-Smith,1981 ANSWERS (Area Non-Point Source Watershed Environment Response Simulation Model)-Beasley,et al.,1980) SOME SOIL EROSION SIMULATION MODELS

  8. DATA COLLECTION • REQUIRED DATA • Rio Panuco Basin • Dem • Slope • Landuse/landcover • Rainfall • Soil • Support Practice • AVAILABLE DATA (PUBLIC DOMAIN) • Rio Panuco Basin (USGS Hydro 1k) • Dem (USGS Hydro 1k GTOPO) • Slope (USGS Hydro 1k GTOPO) • Landuse/landcover(USGS Global Landuse Data) • Precipitation (-Dr. Maidment)

  9. DATA COLLECTION CNTD.
