Regional and local changes in Iraq have led to an accelerated dynamic of comprehensive development without the preservation of local heritage, which caused the loss of many traditional buildings, changing their urban fabric, the emergence of contradictory architectural styles, and others without a clear and specific identity, causing visual deformation. The research problem was identified from the goals and principles of urban design that concerned with the conservation, restoration, and continuity of heritage context, activates their role in sustainable development programs and as a response to changes and radical shifts in spatial structures of city centers, and the social and economic changes, as; “the lack of clear indicators for the restoration of local heritage and its role in achieving spatial development”. The paper will present an analytical study of international and Arabic leading experiences, in the processes of preserving and restoring local heritage, as an important policy in the development and sustainability of places, and try to assess the local experience, according to the indicators derived from them, conduct recommendations for developing the methodologies and policies of restoring local heritage, that suit with the identity and privacy of historical and heritage contexts

Hydrological Operation Requirements for Restoration and Improving Water Quality of Al Qurna Marsh

A hydrological routing study for Al Qurna Marsh was carried out to estimate the hydrological state within the marsh for the Present and future conditions of the marsh. The water surface elevation, area and storage within the marsh at the present and for the future conditions were estimated and the effect of uncontrolled outlets on the hydrological and water quality state of the marsh at the present conditions was specified. The salt mass - balance equation was used to estimate the inflow and outflow discharges that required for reducing the effect of evapotranspiration on the water quality and flashing out the accumulated mass of salts and then improving the marsh water quality. This equation was applied on the future conditions of the
marsh and inflow and outflow discharges that required for this purposes were estimated. Results of the hydrological routing for the present conditions showed that the maximum water surface area is 785 km2 which occur during October. While it is 431km2 during September and it can not be increased during these months since the outlet of the marsh is uncontrolled. The TDS concentration within the marsh
increases during the months of high evapotranspiration although the inflow increases during these months. For the future conditions, the inflow discharges required to sustain the restoration requirements must be increased to decrease the deterioration in the marsh water quality. These discharges increase with the increase in the marsh area
during the months of high evapotranspiration values.

A hydrological routing study for Abu Zirig Marsh was carried out to
estimate the hydrological state within the marsh for the Present and future conditions of the marsh.The water surface elevation, area and storage within the marsh at the present and for the future conditions were estimated and the effect of uncontrolling outlets on the hydrological and water quality state of the marsh at the present conditions was specified. The salt mass balance equation was used to estimate the inflow and outflow discharges that required for reducing the effect of evapotranspiration on the water quality and flashing out the accumulated mass of salts and then improving the marsh water quality. This equation was applied on the future conditions of the
marsh and inflow and outflow discharges that required for this purposes were estimated. The results of the hydrological routing for the present conditions showed that the maximum water surface area is 79 km2 which occur during Spring. While it is between 34 to 43 km2 during Summer and Autumn and it can not be increased during these months since the outlet of the marsh is uncontrolled. The TDS concentration within the marsh increases during the months of high evapotranspiration although the inflow increases during these months. For the future conditions, the inflow discharges required to sustain the restoration requirements must be increased to decrease the deterioration in the marsh water quality. These discharges increase with the increase in the marsh area
during the months of high evapotranspiration values.
