Sea Level Rise Effects On Acidic Pollution In A Coastal Acid Sulphate Soil Area, Ngo Dang Phong, Chu Thai Hoanh, To Phuc Tuong, Reiner Wassmann

Bac Lieu is a coastal province in the Mekong River Delta (MRD), Vietnam. Aside from salinity intrusion from the sea, the province is strongly affected by acidic pollution as 58% of the area (250,000 ha) is overlaid with acid sulphate soil (ASS). Previous studies showed that the eminent sea level rise (SLR) would influence the hydrology and salinity of the canal networks in the province. This study, using the previously validated hydraulic and water quality model CRSAP-ACIDITY (Vietnam River Systems And Plains, coupled with ACIDITY Module), aimed at quantifying impacts of different SLR scenarios (SLR=17, 30, 50, or 75 cm) …

Global sensitivity analysis (GSA) is a valuable tool to support the use of mathematical models for environmental systems. During the last years the water quality modelling field has embraced the use of GSA. Environmental water quality modellers have tried to transfer the knowledge and experience acquired in other disciplines. The main objective of this paper is to provide an informed problem statement of the issues surrounding GSA applications in the environmental water quality modelling field. Specifically, this paper aims at identifying, for each GSA method, the potential use, the critical issues to be solved and the limits identified in a …
Sensitivity And Uncertainty Analysis Of A Plant-Wide Model For Carbon And Energy Footprint Of Wastewater Treatment Plants, Giorgio Mannina, Alida Cosenza, Riccardo Gori, Reza Sobhani, Manel Garrido, Diego Rosso
Sensitivity And Uncertainty Analysis Of A Plant-Wide Model For Carbon And Energy Footprint Of Wastewater Treatment Plants, Giorgio Mannina, Alida Cosenza, Riccardo Gori, Reza Sobhani, Manel Garrido, Diego Rosso

This paper presents the sensitivity and uncertainty analysis of a mathematical model for Greenhouse gas (GHG) and energy consumption assessment from wastewater treatment plants (WWTPs). The model is able to simultaneously describe the main biological and physical-chemical processes in WWTP. Specifically, the mathematical model includes the main processes of the water and sludge lines influencing the methane (CH4), nitrous oxide (N2O), and carbon dioxide (CO2) emissions. Further, the process energy demand and the energy recovery are also taken into account. The main objective of this paper is to analyze the key factors and sources …
