中文摘要: 针对单独水文信息确定水文模型参数的信息量不足问题,以Green-Ampt入渗模型为例,结合同位素混合模型,应用氢氧稳定同位素信息确定Green-Ampt入渗模型参数,并通过室内降雨入渗实验验证。实验结果表明,同位素信息确定的Green-Ampt入渗模型参数与实测值接近,同位素信息和水文信息有效结合确定的模型参数比单一水文信息确定模型参数好。
中文关键词: 氢氧稳定同位素 Green-Ampt入渗模型 同位素混合模型 参数确定
Abstract:Aiming at the deficiency of hydrological information in the estimation of parameters in hydrological models, based on the combination of Green-Ampt infiltration model and isotopic mixing model, parameters were estimated in Green-Ampt infiltration using isotopic information through rainfall infiltration experiment. Experimental results showed that the estimation values of parameters in Green-Ampt infiltration model using isotopic information were close to measured values; parameters obtained by using isotopic and hydrological information were better than those only using hydrological information.
