Description

Environmental modelling frameworks are valuable and increasingly used tools for building customized models, in a context where the complexity of management issues and the availability of data require much flexibility. The LIQUID R framework has been developed since 2005. It is mostly dedicated to hydrological modelling. It aims at easily integrating hydrological processes while preserving their characteristic temporal and spatial scales. LIQUID R allows the user to build and run integrated models on the basis of reusable and exchangeable modules. It provides templates for easy development of new modules, connections to databases and GIS for data input and output, and module coupling mechanisms, that synchronize different time steps and handle irregular geometries. LIQUID R suits a wide range of applications, involving various spatial scales and process conceptualisations. The framework is also able to simulate complex interactions between modules, in particular including feedback. The paper will present the recent advances of LIQUID R , in terms of concepts as well as in terms of technical specifications, and a brief overview of the ongoing main applications. Those deal with the assessment of landscape management impact on hydrology in agricultural and suburban areas, and with the analysis of hydrological responses in the context of flash floods.
