The center of Amman (Downtown) is one of the most marvelous sites in Jordan as it represents a wide range of heritage through time and space. However, the Downtown suffers from severe disorders in terms of negative urban development due to the cross cutting cultures between the past and present. Despite of its historical and cultural richness, several factors affected the architectural uniformi...

A riparian buffer (also known as riparian vegetative filter strips, or buffer strips) is an area of vegetated land surrounding a waterbody, potentially capable of filtering non-point source pollution in runoff from adjacent lands. Main pollutants studied include sediment, nitrogen, phosphorus, bacteria, and pesticides. Although the literature suggests a general consensus about a riparian buffer...

Rapidly increasing urbanization in the world, especially in developing countries, let to increasing urban extents. Rapid urban growth causes to appearance many problems such as wasting environmental resources, inability of providing necessary services for citizens and unplanned growth. Urban mangers and planners need tools for understanding amount and size of future urban growths to prevent the...

growing tendency for urbanization and rapid development of the cities has resulted in urban neighborhoods obstructing the access of each other to the natural sources e.g. solar energy, natural ventilation. sunlight as the main part of input energy in urban energy balance equation and natural lighting is of vital importance. this paper attempts to achieve an optimum morphology for residential bl...

re-vegetation of bare soil is believed to increase, or at least maintain the organic matter levels of soil. the aim of this study was to investigate the soil characteristics changes, nutrient pool sizes and their availability under mid canopy, and canopy gap positions of saltbush in an area re-vegetated with atriplex lentiformis. some of the physical and chemical soil characteristics (the parti...

Physical development without proper planning has limited ecological capacity and the ability of natural ecosystems. Urban river structure as one of the most important ecological infrastructures in the city provides a variety of ecosystem services, including landscaping, climate change, etc. which is strongly dependent on the structure and functional status of the river. This study was conducted...

The concept of low impact development LID is to apply decentralized on-site runoff source control to preserve the watershed hydrologic and ecological functions. An integrated layout using bioretention and vegetated landscape can decrease the developed runoff volume and peak flow. One of the key factors in urban hydrology is the imperviousness in the watershed. The conventional approach is to we...
