CHyM – Cetemps Hydrological Model
CHyM (''Cetemps Hydrological Model'') is a distributed grid-based hydrological model developed by Cetemps Center of Excellence at the University of L'Aquila. It has been created since 2002 by Dott. Marco Verdecchia, Barbara Tomassetti and Erika Coppola. One of the main characteristic of CHyM model is the extensive use of Cellular Automata (CA) based algorithms for drainage network extraction and rainfall data assimilation, for what concerns the specific application in CHyM code, see Coppola et al., 2007. ChyM can simulate the hydrological cycle in any geographical domain with any resolution up to 90 meters; drainage system (geomorphology), drainage network is extracted by a native algorithm implemented in CHyM code, as a consequence no commercial software (like GIS) are needed to run the model. The main aim of CHyM is to provide a general purpose tool for flood alert mapping and hydrological risk management; characteristics of the model also allow to carry out long term simulation ...

Hydrological Model
A hydrologic model is a simplification of a real-world system (e.g., surface water, soil water, wetland, groundwater, estuary) that aids in understanding, predicting, and managing water resources. Both the flow and quality of water are commonly studied using hydrologic models. Conceptual models Conceptual models are commonly used to represent the important components (e.g., features, events, and processes) that relate hydrologic inputs to outputs. These components describe the important functions of the system of interest, and are often constructed using entities (stores of water) and relationships between these entitites (flows or fluxes between stores). The conceptual model is coupled with scenarios to describe specific events (either input or outcome scenarios). For example, a watershed model could be represented using tributaries as boxes with arrows pointing toward a box that represents the main river. The conceptual model would then specify the important watershed feature ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
