Developing a comprehensive framework for eutrophication management in off-stream artificial lakes

Industrialization of Nature in the Time of Complexity Unawareness: The Case of Chitgar Lake, Iran

“…The lake of the Martyrs of the Persian Gulf also known as Chitgar, which is an artificial lake in Tehran, opened in May 2013 to enhance ecological wellbeing, tourism, recreation capacity, and the economy of the region (Zeyaeyan et al, 2017). The idea of Chitgar Lake dates back to 1960s when in the comprehensive city plan of Tehran, a lake was predicted to be in the western part of the city to serve as a flood retention pond for its upstream urban watershed (Khorasani et al, 2018). After decades of postponing stemmed from a lack of funding and low priority, this plan once again was proposed in the second and third comprehensive plans of Tehran later by embedding ecological and recreational concerns.…”

“…However, the eutrophication and algal bloom in Chitgar impede this destination to reach its recreational goals. On the other side, the lake is blamed for preventing southern agricultural land of Tehran to receive adequate water (Khorasani et al, 2018). Moreover, a considerable amount of water also is required for the green space of the lake.…”

“…Previous studies have comprehensively observed the problems and proposed solutions for the water quality management and eutrophication management of the lake focusing on various stakeholders (Estalaki et al, 2016;Khorasani et al, 2018). However, unlike previous studies, the current research tries to address the views of marginalized locals/users of the lake rather than the aforementioned list of governmental institutions.…”

Lake Evaporation Mitigation Using Self-Assembled Films: Case Study Of Chitgar Lake

“…The plain is in the critical situation of groundwater level (Bagheri et al, 2020), and Ali-Khan wetland has recently been exposed to drought and extinction. In another word, Chitgar lake is one of the water reduction sources of the river downstream (Khorasani et al, 2018), moreover, the high growth of algae due to eutrophication affects the recreational and utilization of the lake (Khorasani et al, 2018) is another main challenge that the lake is facing since the operation, and all of two challenges will be solved by reducing evaporation. This is especially becoming more important in summer when the most evaporation occurs and causes increase in phosphorous concentration that leads to algal bloom (Yan et al, 2019).…”

Estimation of chlorophyll-a in urban lakes using drones

“…Urban lakes are strongly affected by development al activities (Henny & Meutia, 2014) and are being eutrophicated, which requires complicated, long-term, and expensive environmental recovery (Vásquez & De-Rezende, 2018). The degradation of lake ecosystems is often aggravated by limited monitoring and diagnostic programs (Khorasani, Kerachian, & Malakpour-Estalakia, 2018). Therefore, we must develop effective methods of managing such ecosystems (Zhang et al, 2018) and establish periodic monitoring programs for their Casenave, 2019), and conducted spatial and temporal monitoring (Dörnhöfer & Oppelt, 2016).…”
