A variety of hydrological models is currently available. Many those employ physically based formulations to account for the complexity and spatial heterogeneity natural processes. In turn, they require a substantial amount data, which may not always be available at sufficient quality. Recently, top-down approach distributed rainfall-runoff modelling has been developed, aims combining accuracy s...

This paper investigates the influence of mean areal rainfall estimation errors on a specific case study: the use of lumped conceptual rainfall-runoff models to simulate the flood hydrographs of three small to medium-sized catchments of the upper Loire river. This area (3200 km2) is densely covered by an operational network of stream and rain gauges. It is frequently exposed to flash floods and ...

Hydrological modelling plays a crucial role in the planning and management of water resources, most especially in water stressed regions where the need to effectively manage the available water resources is of critical importance. However, due to the complex, nonlinear and dynamic behaviour of hydro-climatic interactions, achieving reliable modelling of water resource systems and accurate proje...

The paper presents a modelling framework to integrate dynamic analysis and spatial analysis, and to apply this to a hydrological application. The dynamic analysis runs a simulation of a set of process modules. Modules for spatial analysis functionality are implemented in software libraries, or components. Currently we support components for a map algebra language called MapScript, and for sprea...

Environmental remote sensing has matured significantly over the past two decades as a result of new satellites and intensive airborne campaigns. As such, current remote sensing technology has a huge potential for hydrologic prediction in ungauged basins, through an ability to measure many land surface states, fluxes and parameters that impact on basin prediction. For instance, it is now possibl...

Surface waters and urban drainage systems are usually studied separately. However there are important interactions between both systems. Urban drainage systems can have an important impact on the surface waters, mainly at combined sewer overflows. On the other hand during periods of high water levels in a river, the runoff from the urban drainage system can be significantly influenced by backwa...

To simulate the runoff process at short-term aggregation scale (typically one day) the shot noise model has gained considerable reputation. In this paper, the model developed by Murrone et al. (1997) is taken as a notable example of physically-consistent framework to discuss the different aspects related to the building and estimation of a stochastic tool for time-series generation. In particul...
