“…It is carried out through a conceptual reservoir-based model named SOCONT developed by Consuegra and Vez (1996) and similar to the GR-models (Edijatno and Michel, 1989). It is composed of two reservoirs, a linear reservoir for the slow contribution of soil and underground water and a non-linear reservoir for direct runoff.…”

Abstract. In high mountainous catchments, the spatial precipitation and therefore the overall water balance is generally difficult to estimate. The present paper describes the structure and calibration of a semi-lumped conceptual glaciohydrological model for the joint simulation of daily discharge and annual glacier mass balance that represents a better integrator of the water balance. The model has been developed for climate change impact studies and has therefore a parsimonious structure; it requires three input times series -precipitation, temperature and potential evapotranspiration -and has 7 parameters to calibrate. A multi-signal approach considering daily discharge and -if available -annual glacier mass balance has been developed for the calibration of these parameters. The model has been calibrated for three different catchments in the Swiss Alps having glaciation rates between 37% and 52%. It simulates well the observed daily discharge, the hydrological regime and some basic glaciological features, such as the annual mass balance.

SUMMARYThe second part of this review on streamflow génération analyses how the knowledge available from field studies (see Part 1) has been used since the 1960s or could be used to improve catchment modelling. After a présentation of the main mode! types, the various problems encountered during the modelling process are discussed.The large variety of hydrologie models available for event or continuous simulation can be reduced to a few main types according to the ways the functional, spatial and temporal aspects of the catchment behaviour are represented. Lumped "blackbox" models are useful for many engineering problems but can not be used in "extrapolation" and give no information on the internai catchment dynamics. Lumped conceptual models, which consider a catchment as a System of interconnected réservoirs and simulate the main global fluxes, use empirical lumped relationships and parameters that often hâve no great physical meaning and are not measurable. Semi-distributed conceptual models use the same réservoir description, but at the scale of "homogeneous" units derived from a space discrétisation, which allows one to take catchment structure explicitly into account. Physicaliy-based distributed models, which use theoretical équa-tions and measurable parameters, provide a dynamic explanation of catchment behaviour but require too much information and are too complex to be easily used at the catchment scale. Physico-conceptual semi-distributed models try to overcome the limits of the previous types, while keeping their advantages, by simplifying the dynamic approach and discrétisation using new concepts.Physically-based or conceptual models, which describe or explain the water cycle at the catchment scale, are very useful for research, but their use in prac- Correspondance : ambroise@geographie.u-strasbg.fr Partie 1 publiée dans Rev.

“…These models are powerful but difficult to operate, largely because of the large amount of data needed to calibrate them. Although not recent (Crawford and Linsley, 1963;Nash and Sutcliffe, 1970;Sorooshian and Gupta, 1983;Edijatno and Michel, 1989), conceptual models require fewer parameters, remain widely used since they are very efficient for rainfall runoff modelling when only limited data are available. Moreover the development of computational power and optimisation procedures make it possible to explore the behaviour of these models more efficiently (Yapo et al, 1998;Madsen, 2000;Hreiche et al, 2002) and to study in detail the continuing problem of the non-uniqueness of the parameter sets.…”

This paper presents a model of a heavily managed coastal Mediterranean wetland. The hydrosystem studied , called "Ile de Camargue", is the central part of the Rhone river delta. It comprises flat agricultural drainage basins, marshes, and shallow brackish lagoons whose connection to the sea is managed. This hydrosystem is subject to strong natural hydrological variability due to the combination of a Mediterranean climate and the artificial hydrological regime imposed by flooded rice cultivation. To quantify the hydrological balance at different spatial and temporal scales, a simplified model is developed -including the basin and the lagoons -using a time step that enables the temporal dynamic to be reproduced that is adapted to data availability. This modelling task takes into account the functioning of the natural and anthropogenic components of the hydrosystem. A conceptual approach is used for modelling drainage from the catchment, using a GIS to estimate water input for rice irrigation. The lagoon system is modelled using a two-dimensional finite element hydrodynamic model. Simulated results from the hydrodynamic model run under various hydro-climatic forcing conditions (water level, wind speed and direction, sea connection) are used to calculate hydraulic exchanges between lagoon sub units considered as boxes. Finally, the HIC ("Hydrologie de l'Ile de Camargue") conceptual model is applied to simulate the water inputs and exchanges between the different units, together with the salt balance in the hydrosystem during a calibration period.
