MASSACHUSETTS INSTITUTE OF TECHNOLOGY Department of Civil and Environmental Engineering 1.020 Ecology II: Engineering for Sustainability Problem Set 1 –Salination in Irrigated Agriculture Due: 5PM Tuesday Feb. 19, 2008 Problem Description This modeling exercise considers the problem of salt accumulation in irrigated agriculture. The system of interest includes a river and two farms that divert irrigation water from the river and discharge drainage water back to the river. Water and salt accumulate in the soil below each farm. Relevant mass flows and storages are shown in the figure below. Each box is a separate mass balance control volume.
