Using a Catchment Contour Approach for Simulation of Ground and Surface Water Behaviour Within Agent
نویسنده
چکیده
Agent based modelling (ABM) environments are becoming increasingly popular for investigating the effects of land use change. The ABM environment enables models to be developed that simulate biophysical, economic and social processes at different spatial and temporal scales. The smallest spatial area modelled here is the paddock at a daily temporal resolution, therefore enabling daily interaction of the biophysical and social processes at the paddock scale. Shown here are the steps towards the development of the large scale catchment model that captures the finer spatial and temporal paddock scale processes. These steps involve deciding on the catchment area that captures the land use change to be investigated. Dividing the catchment into subcatchments and defining an appropriate number of contour segments depending on the area of the paddocks to be modelled. Paddock runoff and groundwater flow is modelled using a water balance model. Within each contour segment, runoff is summed and groundwater flow is calculated in a representative radial crosssection using a groundwater model. Contours provide an improvement to catchment modelling as the number of contours generated could also depend on the availability of model parameter data therefore simplifying the reuse of the model within other catchments.

Roughness uncertainty analysis in river flooding using HEC-RAS model
Although flood maps based on the deterministic approach play an important role in minimizing flood losses, there is considerable uncertainty in calculating the level of water inundation. Roughness is a key parameter in water surface elevation. Since roughness is not easily measurable and is estimated based on experimental and laboratory methods, it introduces a significant degree of uncertainty...

متن کاملSurface Pressure Contour Prediction Using a GRNN Algorithm
A new approach based on a Generalized Regression Neural Network (GRNN) has been proposed to predict the planform surface pressure field on a wing-tail combination in low subsonic flow. Extensive wind tunnel results were used for training the network and verification of the values predicted by this approach. GRNN has been trained by the aforementioned experimental data and subsequently was used ...
