  • This paper confronts the question of how the natural processes on and around an alluvial fan are altered by urbanization. Further, the AA. try to point out how some geomorphic principles applied to the urban alluvial fan situation might help provide

  • Rainfall simulation experiments have been used to identify the variables that control rates of gross soil erosion in upland areas of the Fifteenmile Creek drainage in Wyoming. Rates of gross soil erosion were found to be most closely related
  • in badland areas was found to be extreme when compared to the remainder of the drainage.

  • A geomorphological strategy for conducting environmental impact assessments in karst areas
  • The primary goal of this paper is to offer a standard yet flexible approach to karst environmental impact assessments (EIAs) and to show how geomorphological methods can be used to develop more comprehensive and quantifiable EIAs in karst areas
