EIA for lake Maryut sustainable development alternatives using Gis, Rs, and Riam software

Abstract EN

Exploitation of land and water resources has increased rapidly in Alexandria Governorate, paralleling regional population and industrial growth.

Encroachment of urban areas and increase pollution sources are typically considered to have detrimental effects on Lake Maryut ecosystems.

Lake Maryut suffering from different effects including nutrient loading, chemical substances, contaminated sediment, invasive aquatic plants, and wholesale hydrologic alterations, eutrophication is the most widespread pressure impacting on the lake.

In general, its need to be restored using different sustainable development alternatives, by active integration and partnership between all stakeholders, regarding a balance between resources prosperity, social development, cultural values, and ecological integrity, to improve the life quality of human community.

This paper aims to propose three restoration alternatives strategies for Lake Maryut based on the information derived from Remote Sensing, GIS, and field survey, each proposed alternatives are Mechanical, Biological, and Bio-Manipulation Alternatives.

The result obtained by RAPID IMPACT ASSESSMENT MATRIX (RIAM Software) indicates that the most suitable alternatives for Lake Maryut restoration plan are the mechanical alternative, and biological alternative.

On the other hand the "bio-manipulation alternatives" has some significant positive impact on the surrounding environment, and with some negative impacts especially on biological and ecological component.
