摘要:
渠系水利用系数计算结果的准确性对水资源配置、管理和调度影响较大,对灌区渠系水利用系数进行既科学又经济合理的评价是亟待解决的问题。在充分考虑渠道组成、灌溉农田分布、渠道防渗状况、土壤渗透特性、地下水水位的基础上,通过对灌区渠系水利用系数计算公式进行分析推导,得到较为科学的评价无实测资料灌区渠系水利用系数的分布式模型,通过引入灌区修正系数,使得模型参数率定简单易行。同时,根据江都沿运灌区的实际观测对模型参数进行了率定研究。
Abstract:
The accuracy of the calculation results of the canal water utilization coefficient has a great influence on the allocation, management and dispatch of water resources. The scientific and economical evaluation of the canal water utilization coefficient in irrigation areas is an urgent problem to be solved. On the basis of fully considering the composition of canals, distribution of irrigated farmland, anti-seepage conditions of canals, soil seepage characteristics, and groundwater level, by analyzing and deriving the calculation formula of water utilization coefficient of canal systems in irrigation areas, a more scientific evaluation of canal systems in irrigation areas without actual measurement data is obtained. The distributed model of water use coefficient, through the introduction of irrigation area correction coefficient, makes the calibration of model parameters simple and easy. At the same time, the model parameters were calibrated and studied according to the actual observation of the irrigation area along the river in Jiangdu.
