【摘要】：本文旨在將實(shí)時(shí)監(jiān)測(cè)得到的土壤墑情轉(zhuǎn)化為流域水文模型可以直接使用的土壤含水量,論證將實(shí)時(shí)土壤墑情資料用于實(shí)時(shí)預(yù)報(bào)的可行性;利用實(shí)時(shí)監(jiān)測(cè)土壤墑情,改進(jìn)傳統(tǒng)的模型結(jié)構(gòu),設(shè)計(jì)基于實(shí)測(cè)土壤墑情的降雨徑流水文預(yù)報(bào)模型.采用土壤含水量誤差抗差估計(jì)技術(shù)以抵御觀測(cè)資料粗差的影響,提高系統(tǒng)的穩(wěn)定性;并在此基礎(chǔ)上提出了土壤含水量系統(tǒng)響應(yīng)修正方法,以提高模型計(jì)算精度.將該模型應(yīng)用于實(shí)驗(yàn)流域——寶蓋洞流域進(jìn)行應(yīng)用檢驗(yàn),洪水模擬合格率達(dá)到92.3%,整體模擬精度達(dá)到甲級(jí).
[Abstract]:The purpose of this paper is to convert the soil moisture obtained from real-time monitoring into the soil moisture content that can be used directly by the watershed hydrological model, to demonstrate the feasibility of using real-time soil moisture data for real-time forecast, and to use real-time monitoring of soil moisture, Improved the traditional model structure and designed the rainfall runoff hydrological forecast model based on the measured soil moisture. The robust estimation technique of soil water content error is used to resist the influence of gross error of observation data and the stability of the system is improved, and on this basis, a modified method of soil water content system response is proposed to improve the accuracy of the model calculation. The model has been applied to the experimental watersheds-Baogaitong watershed for application test. The qualified rate of flood simulation is up to 92.3 and the overall simulation accuracy reaches Grade A.
