Artificial neural networks have proven to be an attractive mathematical tool to represent complex relationships in many branches of hydrology. Due to this attractive feature, neural networks are increasingly being applied in subsurface modeling where intricate physical processes and lack of detailed field data prevail. In this paper, a methodology using modular neural networks (MNN) is proposed to simulate the nitrate concentrations in an agriculture-dominated aquifer. The methodology relies on geographic information system (GIS) tools in the preparation and processing of the MNN input–output data. The basic premise followed in developing the MNN input–output response patterns is to designate the …
Systematic Framework For Evaluating Treated Wastewater Usage In Agricultural Irrigation, Yasser Kamal Nazzal
Systematic Framework For Evaluating Treated Wastewater Usage In Agricultural Irrigation, Yasser Kamal Nazzal
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A general systematic framework with several sub-frameworks was developed to help managers make informed decisions related to the reuse of treated wastewater in agricultural irrigation. The framework involves the identification and evaluation of the short- and long-term effects of using treated wastewater with some common constituents of concern (e.g. salts and some specific ions, nutrients, heavy metals, organic compounds, and microorganisms) on the environmental elements (crop, soils, surface water, and groundwater), and on the public health. Local and/ or international standards, criteria, and guidelines related to agricultural reuse are applied to the evaluation of the effects. Based on the evaluation …
