Abstract

The present work reports on the study and the comparison of the performance of three “Génie rural” (GR) and two Water Balance (WB) models. The calibration and robustness performances are analysed in the light of the hydro-climatic conditions. The study shows that the GR models are much more efficient and robust than the WB models. The behaviour of calibration performance as a function of hydroclimatic variables varies according to the model and goodness-of-fit criteria (GOFC). The GR models are more robust in terms of NSE(Q) and NSE(√Q) and the WB models in terms of KGE. For more robustness of the models, it is better to transfer the parameters to wetter periods or periods with a lower Potential EvapoTranspiration (PET) than the calibration period. For a loss of robustness of less than 20% for GR and 30% for WB, the variation between calibration and rain validation/PET periods must be around ±15%/±1.5%.

气候变化研究中水文模型的比较:对西非和中非241个集水区的测试
本研究报告了三种“gsamnie rural”(GR)模型和两种水平衡(WB)模型的研究和性能比较。根据水文气候条件分析了系统的标定性能和鲁棒性。研究表明,GR模型比WB模型具有更高的效率和鲁棒性。校准性能作为水文气候变量的函数的行为根据模型和拟合优度标准(GOFC)而变化。GR模型在NSE(Q)和NSE(√Q)方面更稳健,而WB模型在KGE方面更稳健。为了提高模型的鲁棒性,最好将参数转移到比校准期更潮湿或潜在蒸散发(PET)更低的时期。对于GR的稳健性损失小于20%,WB的稳健性损失小于30%,校准和降雨验证/PET周期之间的变化必须在±15%/±1.5%左右。

期刊介绍: Created in 1835 by physicist François Arago, then Permanent Secretary, the journal Comptes Rendus de l''Académie des sciences allows researchers to quickly make their work known to the international scientific community. It is divided into seven titles covering the range of scientific research fields: Mathematics, Mechanics, Chemistry, Biology, Geoscience, Physics and Palevol. Each series is led by an editor-in-chief assisted by an editorial committee. Submitted articles are reviewed by two scientists with recognized competence in the field concerned. They can be notes, announcing significant new results, as well as review articles, allowing for a fine-tuning, or even proceedings of symposia and other thematic issues, under the direction of invited editors, French or foreign.
