A semi-distributed hydrological model was applied to a small forested catcment in southern Finland. The aim was to demonstrate how differences in terrain properties could be taken into account in modelling runoff generation, and to test how well the presented model simulated streamflow with only limited calibration. Modelling was based on subdivision of a catchment into topographically similar ...

A methodology for propagating and constraining the uncertainty inherent in real-time flood forecasting is presented and demonstrated on an application to the River Severn, UK. The flood forecasting system is based on a cascade of rainfall-runoff and flood routing models, developed using stochastic transfer functions with state dependent parameterisations to allow for nonlinearity. The nonlinear...

Rainfall–runoff models are not perfect, and the suitability of a model structure depends on catchment characteristics data. It is important to investigate pros cons rainfall–runoff improve both its high- low-flow simulation. The production routing components GR4J IHACRES were combined create two new models. Specifically, GR_IH combination store (vice versa in IH_GR model). performances compared...

The present study was conducted in Baitarani basin up to Anandapur gauging station of Odisha covering an area 8603.7 km2. Pre-processing from digital elevation model (DEM) done using HEC-Geo-HMS extension and spatial analyst tool ArcGIS. These pre-processed files were then imported HEC-HMS for simulating runoff. In this study, runoff simulation two methods, viz., composite distributed curve num...

Stormwater models underpin decision-making processes in stormwater management. Runoff generation and flow routing models are now well developed and widely adopted. However, stormwater quality models are less well developed. Model calibration and sensitivity analysis are crucial in order to estimate realistic stormwater pollution concentrations. The Metropolis algorithm (Metropolis et al., 1953)...

Land management in the Krueng Jreu sub-watershed (Aceh Province, Indonesia) that did not follow soil and water conservation methods encouraged erosion. This can lead to silting of rivers or irrigation canals due sediment deposition. Limited tools were main reason for infrequent measurement mapping these sediments watersheds. Therefore, this study aims conduct sedimentary using GIS techniques co...

Australian arid zone ephemeral rivers are typically unregulated and maintain a high level of biodiversity and ecological health. Understanding the ecosystem functions of these rivers requires an understanding of their hydrology. These rivers are typified by highly variable hydrological regimes and a paucity, often a complete absence, of hydrological data to describe these flow regimes. A daily ...

[1] The last deglaciation was interrupted by three major cooling events, the Younger Dryas, the Preboreal Oscillation and the 8.2-ka cold event. As the Laurentide Ice Sheet retreated, different outlets from Lake Agassiz became available causing the proglacial lake to drain to a new level in a rather short timescale (flood) and divert continental runoff over hundreds of years (routing). Here we ...

[1] Hydrographs are an enticing focus for hydrologic research: they are readily available hydrological data that integrate the variety of terrestrial runoff generation processes and upstream routing. Notwithstanding, new techniques to glean information from the hydrograph are lacking. After early approaches of graphically separating streamflow components, hydrograph separations in the past two ...
