Development of objective-oriented groundwater models: 1. Robust parameter identification

Assessment of nitrate contamination of groundwater using lumped-parameter models

In this paper, lumped-parameter models (LPMs) were developed and utilized to simulate nitrate concentration in the groundwater of Gaza City and Jabalia Camp (GCJC) in the Gaza Coastal Aquifer (GCA) in Palestine. In the GCJC area, nitrate levels exceed the maximum contaminant level (MCL) of 10 mg/L NO3-N (45 mg/L NO3) in many wells. Elevated nitrate concentrations in the groundwater of GCJC area...

Parameter Estimation in Groundwater Flow Models with Distributedand Pointwise Observations

We present in this paper some results concerning the least sqaures estimation of parameters in a groundwater ow model. As is typically the case in eld studies, the form of the data is pointwise observation of hydraulic head and hydraulic conductivity at a discrete collection of observation well sites. We prove continuous dependence results for the solution of the groundwater ow equation, with r...

Parameter Identification of Autonomous Vehicles Using Multi-objective Optimisation

In order to properly operate an autonomous vehicle navigation system, it is important that the vehicle and sensor models of an autonomous vehicle are defined by an accurate parameter set. This paper presents a technique for identifying parameters of an autonomous vehicle using multi-objective optimisation, which enables the identification process without introducing additional parameters. A mul...

Parameter Identification of Consolidation Settlement Based on Multi-Objective Optimization

Due to the complexity of natural ground condition, consolidation settlement is usually difficult to predict. In this study, a Pareto multi-objective optimization based back analysis method for consolidation settlement is presented in this study. The model is a coupled flow and deformation model for unsaturated soil foundation which is implemented in the interactive multiphysics software environ...
