Abstract

This study investigates the performance of TRMM and PERSIANN satellite rainfall data as input in a reliable rainfall-runoff model in order to provide information to the flood early warning for the Voshmgir Dam, Iran. Calibration of both continuous daily rainfall-runoff and an event-based flood was done using HEC-HMS Nelder-Mead (NM) method. Furthermore, simulations based on daily versus 3-hourly TRMM were compared to evaluate the effect of input time-step of rainfall-runoff model. Results show that the deficit and constant loss method is able to successfully predict the observed runoff. In addition, the Green-Ampt method using 3-hourly TRMM data showed a good capability to simulate daily peak discharges. The current study demonstrates the suitability of HEC-HMS for continuous and event-based runoff simulation in a complex watershed. Therefore, this research will have a significant contribution to the future development of water resources planning in this catchment in particular and in other data-scarce catchments.

利用卫星降雨在稀缺数据集水区进行降雨径流模拟

本文研究了TRMM和PERSIANN卫星降雨数据作为可靠降雨径流模型输入的性能，以便为伊朗voshmir大坝的洪水预警提供信息。使用HEC-HMS Nelder-Mead (NM)方法对连续日降雨径流和基于事件的洪水进行了校准。此外，还比较了基于日和3小时TRMM的模拟，以评估降雨径流模型输入时间步长的影响。结果表明，亏缺法和等损失法能较好地预测实测径流。此外，使用3小时TRMM数据的Green-Ampt方法显示出很好的模拟日峰值放电的能力。目前的研究证明了HEC-HMS在复杂流域连续和基于事件的径流模拟中的适用性。因此，本研究将对该流域水资源规划的未来发展做出重大贡献，特别是在其他数据稀缺的流域。
