Paper Title:
Simulating the Impacts of Land Use/Cover Change on Storm-Runoff for a Mesoscale Watershed in East China
  Abstract

This study aims to explore the impacts of Land use/cover change (LUCC) on storm-runoff by simulating two typical flood events for five land cover scenarios in a mesoscale watershed in east China by distributed hydrologic modeling system HEC-HMS. It was concluded from the modeled hydrographs that built-up land will reduce the basin’s ability of smoothing flood wave by changing flood peak remarkably, while forestation will mitigate and postpone flood peak. The statistic analysis of the key flood parameters, runoff coefficient and peak discharge, produced by five different land covers exhibited highly quantitative relationships, from which we may estimate the runoff changes due to land use/cover changes under 5-year return period typhoon rain or Plum rain. The study provides some information on the influences of LUCC on storm-runoff by modeling approach and it will contribute to flood control and management in Tai Lake Basin in east China.
