Hydrological model coupling with ANNs
There is an increasing need for model coupling. However, model coupling is complicated. Scientists develop and improve models to represent physical processes occurring in nature. These models are built in different software programs required to run the model. A software program or application represents part of the system knowledge. This knowledge is however encapsulated in the program and ofte...
متن کاملIntegration and Coupling of Hydrological Models with Water Quality Models:
Conceptual watershed model developed to examine water quality as it is affected by soil erosion from agriculture and urban areas (Young et al., 1987). AGNPS has three major components: hydrology, soil erosion and nutrient pollution. The hydrological function provides prediction of runoff volume and peak flow rate. The soil erosion function includes soil erosion and sedimentation. The nutrient f...
متن کاملCoupling a distributed grid based hydrological model and MM5 meteorological model for flooding alert mapping
The increased number of extreme rainfall events seems to be one of the common feature of climate change signal all over the world (Easterlin et al., 2000; Meehl et al., 2000). In the last few years a large number of floods caused by extreme meteorological events has been observed over the river basins of Mediterranean area and they mainly affected small basins (few hundreds until few thousands ...
متن کاملMultivariate contemporaneous ARMA model with hydrological applications
In order to allow contemporaneous autoregressive moving average (CARMA) models to be properly applied to hydrological time series, important statistical properties of the CARMA family of models are developed. For calibrating the model parameters, efficient joint estimation procedures are investigated and compared to a set of uivariate estimation procedures. It is shown that joint estimation pro...
متن کاملCoupling between subtropical cloud feedback and the local hydrological cycle in a climate model
In HadGEM2-A, AMIP experiments forced with observed sea surface temperatures respond to uniform and patterned ?4 K SST perturbations with strong positive cloud feedbacks in the subtropical stratocumulus/trade cumulus transition regions. Over the subtropical Northeast Pacific at 137 W/26 N, the boundary layer cloud fraction reduces considerably in the AMIP ?4 K patterned SST experiment. The near...
