摘要: The effect of urban form on Curve Number (CN) use in rainfall-runoff modelling is explored an arid wadi watershed Oman. standard hydrologic CN used the Soil Conservation Service method may not be appropriate to urbanized regions since land-use characteristics are different than those for which was developed for. In this paper a new described develop regional regions. modified then predict peak-flow and time-to-peak compared results from method. values produce higher (an increase 19% or 7.4 m3/s, average) with shorter (a decrease 16% 86 minutes, average), mimicking flash-floods seen region. addition, were model change hydrology caused by urbanization.
