Abstract
A source of contaminated groundwater is governed by the disposal of waste material on a land fill. There are many people in rural areas where the primary source of drinking water is well water. This well water may be contaminated with groundwater from landfills. In this research, a two-dimensional mathematical model for long-term contaminated groundwater pollution measurement around a land fill is proposed. The model is governed by a combination of two models. The first model is a transient two-dimensional groundwater flow model that provides the hydraulic head of the groundwater. The second model is a transient twodimensional advection-diffusion equation that provides the groundwater pollutant concentration. The proposed explicit finite difference techniques are used to approximate the hydraulic head and the groundwater pollutant concentration. The simulations can be used to indicate when each simulated zone becomes a hazardous zone or a protection zone.
Highlights
The importance of the utilization of groundwater resources continues to grow due to the increasing requirement for water for irrigation, drinking, commercial, agricultural and industrial proposes
A method to set up the initial condition and boundary conditions of the proposed transient groundwater flow model is proposed
The results from the second model will be inputted into the third model as field data
Summary
The importance of the utilization of groundwater resources continues to grow due to the increasing requirement for water for irrigation, drinking, commercial, agricultural and industrial proposes. Contaminated water can cause many types of diarrheal diseases, including Cholera, and other serious illnesses, such as Guinea worm disease, Typhoid and Dysentery The solution to this problem is to approximate when the water from the primary source of drinking will become a hazardous zone. The simulation of the contaminated groundwater pollution model required data concerned with the velocity of the current points and any time in the domain. Finite difference methods, including both explicit and implicit schemes, are mostly used for two-dimensional domain such as in latitude and longitude stream. These two mathematical models were used to simulate contaminated groundwater pollution.
