The rate at which liquids can be added to a vertical well, the lateral zone of impact of the well, and the liquids volume needed to wet the waste within the zone of impact of the well are the key inputs needed to design a vertical well system. This paper presents design charts that can be used to estimate these inputs as a function of municipal solid waste properties (porosity, hydraulic conductivity, and anisotropy ratio), well dimensions (radius and screen length), and injection pressure. SEEP/W modeling was conducted to estimate the key design inputs for a range of conditions practically encountered for a vertical well installed in landfilled waste. The flow rate, lateral zone of impact of a well, liquids volume added, and injection pressure were normalized with the waste properties and well dimensions to formulate dimensionless variables. A series of design charts were created to present dimensionless steady-state flow rate, lateral zone of impact, and the dimensionless liquid volume needed to reach a steady-state condition, as a function of dimensionless input variables. By using dimensionless variables formulated for this work, these charts permit the user to estimate the steady-state design variables described above for a wide range of configurations and conditions beyond those simulated without the need for further modeling. The results of the study suggest that the lateral extent of the well can be estimated using Darcy’s equation and assuming saturated unit-gradient vertical flow regime below the well bottom. An example problem is presented to illustrate the use of the design charts. The scenario described in the example problem was also modeled with SEEP/W, and the results were compared with those obtained from the design charts to demonstrate the validity of design charts for scenarios other than those used for the development of the design charts. The methodology presented in this paper should be thought of as a means to provide a set of bounds that an engineer can use along with their judgment in the design of a system for a specific site. 相似文献

This research examines how each of the design variables associated with the design of residential curbside recycling programs affects the participation rate, as well as the effect of interactions between the variables. The evaluation of each design variable includes a literature review and an analysis of the results of six published surveys of curbside recycling programs. The results of this research show that there is no single ideal design for residential curbside recycling programs, but that a variety of combinations of design variables have proven to be successful. This suggests that when designing a recycling program, the costs, needs and goals of the community should be significant factors while taking into consideration the effect of some design variable options on participation. Based on these results, four residential curbside recycling programs were designed: two to maximize participation rates without significant regard to cost; and the other two with the goal of achieving a balance between participation rate and program cost. 相似文献
