A Dynamic Programming Approach to a Class of Nonpoint Source Pollution Control Problems

Abstract

This paper presents a new approach to modeling, analyzing, and solving a class of environmental control problems dealing with sediment deposition. An efficient dynamic programming algorithm is designed to handle the spatial characteristics of soil movement through a watershed, and its ultimate impact on water channels and/or reservoirs. The model generates "sediment abatement cost frontiers" which summarize the trade-off information needed for watershed planning and management. This information can also be used to identify and target special-problem areas. The paper presents both results on the efficiency of the DP algorithm compared to other methods, and results on the application of the model to real world cases.pollution, watershed, agriculture

Assessing the economic performance of an environmental sustainable supply chain in reducing environmental externalities

“…Bloemhof-Ruwaard et al (1995) observed the earliest studies on the application of operational research (OR) optimization models to environmental management (e.g., Böttcher and Rembold, 1977;Das and Haimes, 1979;Batta and Chiu, 1988;Ellis, 1988;Bouzaher et al, 1990). Brandenburg et al (2014) observed that, among the extant research related to the SCM perspective, sustainability is often externally motivated by the government, the customers or stakeholders (e.g., Gold et al 2010;Seuring and Müller, 2008), and a vertical coordination for improving environmental performance among supply chain firms is required (Carter and Rogers, 2008).…”

Validation of EPIC for Two Watersheds in Southwest Iowa

“…Integrated modeling systems range from farm-level (Foltz et al 1993;Taylor et al 1992;Wossink et al 1992), to watershed (Bouzaher et al 1990;Lakshminarayan et al 1991), and ultimately to regional (Bernardo et al 1993;Bouzaher et al 1995;Lakshminarayan et al 1996) applications. In each of these systems, functions and/or models are incorporated to predict environmental indicators for different combinations of landscape, soil, management, and climate conditions.…”
