“…If inflows are obtained by hydrologic modelling, we can call it a hydrologic and hydraulic model coupling. Some examples of coupling have already been detailed in the literature (see, for example, Knebl et al, 2005;Whiteaker et al, 2006;Lian et al, 2007;Biancamaria et al, 2009;Bonnifait et al, 2009;Montanari et al, 2009;Mejia and Reed, 2011;Kim et al, 2012;Lerat et al, 2012). A single application concerns a catchment prone to fast floods: the study of Bonnifait et al (2009), which proposes a coupling of the hydrologic n-TOPMODELs model to the CARIMA hydraulic model.…”

Abstract. Mediterranean catchments are regularly affected by fast and flash floods. Numerous hydrologic models have been developed, and allow modelling of these floods. However, these approaches often concern average-size basins of a few hundred km 2 . At larger scales (> 1000 km 2 ), coupling of hydrologic and hydraulic models appears to be an adapted solution. This study has as its first objective the evaluation of the performances of a coupling of models for flood hydrograph modelling. Secondly, the coupling results are compared with those of other modelling options. The aim of these comparisons is to clear up the following points. (1) Is a simplified routing model (lag and route) as efficient as a full hydraulic model for the modelling of hydrographs, in the intermediary downstream part of the stream? (2) Is adding lateral inflows necessary for all studied events? (3) What is the impact of the qualities of upstream hydrologic modelling feeding the coupling? The coupling combines the SCS-LR (Soil Conservation Service-lag-and-route) hydrologic model of the ATHYS platform and the MASCARET 1-D hydraulic model based on full Saint-Venant equations. It is applied to the Gardon River basin (2040 km 2 ) in the south of France. For the seven studied events, the results of the coupling are satisfactory, the calculated Nash indexes varying between 0.61 and 0.97. The comparisons with the other modelling options show the important role of the spatial distribution of rains during events: when rains are centered on the intermediary downstream part of the catchment, adding lateral inflows is necessary; when rains are more important in the upstream part, the quality of the hydrologic modelling upstream of the coupling has a strong impact. Furthermore, the used coupling of models seems well adapted for water rising and flooded area forecasting. The future developments of the tool will concentrate on this point.

“…According to the "Standard for hydrological information and hydrological forecasting (GB/T 22482-2008)," in this work we proposed four model performance classes as a guidance on reference Nash coefficient range, which were denoted as Unsatisfactory (Nash coefficient < 0.5), Acceptable (0.5 ≤ Nash coefficient < 0.7), Good (0.7 ≤ Nash coefficient < 0.9), or Very good (Nash coefficient ≥ 0.9) [48]. The Nash coefficients of 19 Table 10 illustrates that the probability of the model fit being considered Unsatisfactory, Acceptable, Good, and Very good was 0%, 16.67%, 83.33%, and 0%, respectively. So the calculation of rainfall losses was feasible.…”

Abstract:Basins located in loess hilly-gully regions often suffer flood disasters during the flood season. Meanwhile, the underlying surface of the region can increase the rainfall losses, thereby reducing the flood volume. Therefore, the prediction of rainfall losses on the underlying surface is necessary for scientifically and reasonably forecasting the flood volume. The relationship between the rainfall losses and underlying characteristics was investigated and a method for predicting the rainfall losses using HEC-HMS was presented in this paper with a case study in the Gedong basin, a typical loess hilly region of western Shanxi Province in northern China. Results showed that HEC-HMS could be applied to loess hilly-gully regions. The loss computation results suggested that the losses of sub-basins varied with the density of rainfall. The analysis of influences of rainfall losses, including forestland percentage and slope, indicated that the former had a positive impact, while the latter had a negative influence. The impact of forestland percentage is larger than that of slope. Furthermore, with the increase of forestland percentage, its correlation with rainfall losses was enhanced, and the correlation coefficient ranged between 0.64 and 0.84 from the 1970s to the 2010s.

The study presented herein investigates the impact of simulated changes in land cover on rainfall-runoff conditions for the transboundary basin of the upper Lužnice. The HEC-HMS hydrological model was chosen for these simulations. Scenario models were used to simulate the impact of modifications in basin land cover with individual scenarios reflecting ground cover changes. The years 1990 and 2000, which are available in the CORINE Landcover database, were chosen as variants of river basin land cover. In addition, two theoretical versions of possible extreme variants in fundamental land cover changes -the conversion from agricultural land to grassland and the forestation of the river basin, with the exception of roads and bodies of water -were also included.Single day rainfall totals with a recurrence period of 10, 20, 50 and 100 years were selected to calculate the volume of runoff and culmination discharge. These results demonstrate a clear decrease in the degree of impact of land cover structure on runoff conditions, increasing with the magnitude of precipitation. Článek představuje výsledky simulace vlivu zm n krajinného krytu na srážko-odtokové pom ry v přes-hraničním povodí horní Lužnice. Pro modelování byl vybrán hydrologický model HEC-HMS. K modelování vlivu zm n krajinného pokryvu povodí byla použita metoda scénářového modelování, kde se v jednotlivých scénářích m ní krajinný pokryv. Jako varianty krajinného pokryvu povodí byly zvoleny roky 1990 a 2000, pro které je k dispozici databáze CORINE Landcover, a dále dv teoretické krajní varianty možných variant zm n struktury krajinného krytu -zatravn ní zem d lské půdy a zalesn ní povodí krom intravilánů, komunikací a vodních ploch.Pro výpočet objemů odtoků a kulminačních průtoků byly vybrány jednodenní návrhové srážkové úhrny s pravd podobností opakování 10, 20, 50 a 100 let. Z výsledků simulace je zřejmý pokles vlivu struktury krajinného pokryvu na odtokové pom ry se vzrůstající extremitou srážky.
