The new method for estimating river discharge in un-gauged basins is developed by integrating satellite observations and hydrological model. This method allows estimation of river discharge considering local hydrological and hydraulic characteristics in the poorly-gauged/un-gauged river basin. This proposed method has potential to be applied for the river basin management in developing countries and regions where hydrological observation network is not sufficiently installed.

将卫星观测与水文模型相结合，提出了一种估算非计量流域河流流量的新方法。该方法允许在测量不准确或未测量的流域中考虑当地水文和水力特征来估计河流流量。该方法具有应用于发展中国家和水文观测网不完备地区的流域管理的潜力。
