Model Calibration and Prediction ECE Final Year Project Report provides detailed explanation about the project.Here we provide introduction to the project.
By using calibration a steady state mode is studied. Different studies are calibrated and compared to obtain a non unique solution. After calibration pumping wells are introduced into the model to predict heads and draw downs. From the obtained particle tracking code modpath is checked for contamination of wells. Here the calibration parameters which are used for the design of 3 layers 11 columns and16 rows are discussed.
Model input and Hydraulic conductivity:
The time unit for the calibration is years and recharge rates and et rates and pumping rates and fluxes are computed against years. By using the hydraulic conductivity we can enter the lithology of acquifer into properties menu. The acquifer consists of the information of the layers.
The vertical hydraulic conductivity is entered between the layers by using leakance. It is used for describing vertical transmission properties of the layers. The leakance consists of vcount calculation parameter. By using the vcount we can enter the input of leakance to mud flow.
It is an input of the upper layer which gives the pattern of the recharge rates. We can estimate the recharge rates by assuming the percentage of perception falling in the mountains.
In the area around the plya the evapotranspiration occurs. With out using the evapotranspiration we cannot give the land surface input to the mudflow. The problems which occurs in model is that the evapo transpiration may cause some of the to go dry. But the mudflow takes he cell dries out of simulation. By using the gwvistas values the calibration process is calculated.
