The Gavkhouni International Wetland, located in the central plateau of Iran, holds significant importance for various reasons. Its significance and the issues of drought and its consequences in recent years have prompted many experts and groups to conduct diverse studies and research on this wetland. Despite the wetland’s importance and the studies done, there hasn’t been a comprehensive database created, and information was scattered and unorganized. This database contains projects and articles related to the Gavkhouni Wetland and Zayandeh River, aiming to collect this information and make it publicly accessible.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Year of Execution<\/strong>: 2017<\/p>

Project Summary<\/strong>:<\/p>

This project was carried out to ensure the continuity of the ecological functions of the Zayandeh River and the International Gavkhouni Wetland.<\/p>

In this study, the Gavkhouni basin was zoned based on various data obtained from three main project tasks: basic studies and spatial data, hydrology and climate, and biota studies and water quality. This was done considering biological indicators, water quality, hydrological and river morphology, erosion and sedimentation, water sources and uses, riverside land use and its changes.<\/p>

Based on the findings, the final zoning of the river and the wetland was done to offer management strategies and water allocation scenarios. As a result, 7 management zones were identified.<\/p>

Furthermore, the required environmental flow of the Zayandeh River and Gavkhouni Wetland for maintaining their ecological functions was estimated using a combined method. This involved habitat simulation based on the biological needs of indicator fish species using the PHABSIM model and ensuring water quality using regression.<\/p>

Additionally, the results from the combined method were compared with those from hydraulic and hydrological methods. Based on this, the environmental flow rate of 10, 7, and 5.5 cubic meters per second, respectively, for intervals 1 to 5 (upstream of the Zayandeh Dam to the Waterfall Dam), interval 6 (from the Waterfall Dam to Varzaneh), and interval 7 (Gavkhouni Wetland) were determined.<\/p>

The study also provided an annual timetable to ensure the river and wetland’s environmental quota considering various factors. In the end, six management scenario solutions for ensuring environmental needs were presented.<\/p>

In this study, the environmental quota for the Gavkhouni Wetland, in accordance with this project, is suggested to be about 13% of the basin’s average long-term volume (1,398 million cubic meters annually) or equivalent to approximately 15% of the natural basin volume and Kouhrang 1 tunnel, as the environmental quota of Gavkhouni Wetland (173.25 million cubic meters annually).<\/p>

1) Environmental Risk Assessment of Wetlands Using TOPSIS and EFMEA Methods (Case Study: Gavkhouni International Wetland)<\/strong><\/p>

Authors: Raqiye Mekvandi, Sajjad Aastani, Bahare Lorestani
Published in: 2015
Source: Environmental Research Journal<\/p>

Summary<\/strong>:
This study was conducted in 2012 with the purpose of identifying and analyzing the risks threatening the Gavkhouni wetland. The area of study is located at the most downstream part of the Zayandeh-rood river basin, within the Gavkhouni sub-basin, about 107 kilometers southeast of the city of Isfahan.<\/p>

The results show that the risks of drought, reduced wetland water, and the construction of the Zayandeh-rood dam are ranked first and second, respectively. After determining the priority number of the risk using the TOPSIS method, the degree of vulnerability of the risks was identified, which indicates the managerial priorities for risk control.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

2) Investigating Livelihood Alternation as a Solution to Reduce the Effects of Drying of the Zayandeh-rood River and Gavkhouni Wetland \/ Case Study: Varzaneh City<\/strong><\/p>

Authors: Shahbaz Mehrabi, Mohammadreza Yazdani, Asghar Tosli
Published in: 2017
Source: Scientific and Research Quarterly of Crisis Management<\/p>

Summary<\/strong>:
This research explores the potential of shifting livelihoods as a way to enhance the resilience of the fragile community in Varzaneh city. The study is practical in its aim and is descriptive-survey in nature. Results indicate that the community engagement level in Varzaneh city is satisfactory (3.31), their familiarity with livelihood rotation is low (2.45), but there is a high inclination (3.12) towards choosing alternative professions. The primary reason for this is the drying of the river and a decrease in the efficiency of agricultural and livestock products. Additionally, results show that carpet weaving has a higher popularity among the residents compared to agriculture, livestock, tourism, and water well digging.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

5) Paleo-climate Analysis of the Northern Section of Gavkhouni Wetland Using Main and Trace Element Geochemistry<\/strong>
Authors: Leila Taghavi, Safieh Tayebi, Sobhan Tayebi, Behram Karimian
Published in: 2013

Summary<\/strong>:
The Gavkhouni Wetland is a graben that’s covered by Quaternary sediments. This research, conducted in 2010 at the Gavkhouni International Wetland, delves into the climatic variations of the northern part of the wetland based on sedimentological chemistry, namely main and trace elements. Sedimentological evidence, which includes studying erosion processes and examining sediments such as composition and sedimentary conditions, are vital clues for analyzing past climatic conditions.<\/p>

From the tested samples, a categorization of past climatic conditions in the region has been deduced. Based on all the evidence, it seems that at depths of 100 and 140 centimeters, dry periods were experienced, while at depths of 60 and 200 centimeters, wetter periods are evident. In the topmost 20 centimeters of the core, which corresponds to current day sediments, the conditions appear to be semi-arid or transitional.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

6) A Study on the Role of Dried Surfaces of Gavkhouni Wetland in the Production of Local Dust and Storms Using Landsat Images and Dust Storms (Case Study: Isfahan City)<\/strong>
Authors: Zahra Ebrahimi Khosfi, Abbasali Vali, Mohammad Khosroshahi, Reza Ghazavi
Published in: 2017
Source: Scientific-Research Journal of Rangeland and Desert Research in Iran<\/p>

Summary<\/strong>:
The main objective of this research is to investigate the influence of dried surfaces of the Gavkhouni Wetland on the production of local dust and storms in the Isfahan station, leveraging remote sensing techniques and analyzing dust storms over a 22-year period from 1991-1992 to 2012-2013.<\/p>

Results derived from correlation analysis demonstrate a significant inverse relationship between the number of dusty days and dried surfaces of the wetland during autumn, spring, and summer seasons on an annual scale at the Isfahan station. Furthermore, findings from studying the direction of dust-bearing winds using dust storms indicate that these winds do not blow from the Gavkhouni Wetland towards Isfahan.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Summary<\/strong>:
This research was conducted to examine the effects of drought on the Gavkhouni Wetland. The results indicate that if the current trend continues, the Gavkhouni Wetland may undergo an intensifying desertification process, leading to playa-like evolutions. An increase in salty mineral deposits on the alluvial sediments and the expansion of the saline zone might transform the wetland into a desert.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Authors: Eisa Ebrahimzadeh, Jafar Karimi
Publication Year: 2011
Published In: Scientific-Research Journal of Geography and Planning (Tabriz University)<\/p>

Summary<\/strong>:
In this paper, based on meteorological data of stations neighboring the Gavkhouni Wetland, namely Isfahan, East Isfahan, Kabootarabad, Bafq, and Yazd over the years from 1975 to 2005, human comfort conditions were analyzed and scrutinized according to various models and bioclimatic indices. Research findings suggest that, considering the region’s climatic characteristics and having a variety of appealing natural attractions such as mountains, deserts, lakes, green plains, gaz forests, and the historical region of Varzaneh and Ghurtan nearby, it holds great potential and attraction for ecotourism planning.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Published In: Ecohydrology Journal<\/p>

Summary<\/strong>:
The research goal is to study the sustainability of various scenarios to enhance agricultural water use management. These scenarios include modernizing and improving the efficiency of agricultural water distribution systems, improving the performance of on-farm irrigation systems, optimizing cultivation patterns, reducing groundwater resource exploitation, and a combination of these scenarios to rejuvenate the environmental rights of the wetlands. The results showed that the most adaptable scenario is the implementation of all the mentioned scenarios with a sustainability index of 87.3%. Following that, the implementation of the scenarios related to modernizing and improving the efficiency of agricultural water distribution, optimizing cultivation patterns, and reducing groundwater resource exploitation has a sustainability index of 81.6%.<\/p>

Implementing a comprehensive combination of the agricultural water demand management scenarios can be the most sustainable solution for the revival of the Gavkhouni Wetland.<\/p>

15) Monitoring Changes in the Surface Level of Gavkhouni Wetland and its Relation to Dust Storms and Movement of Surrounding Sand Dunes<\/strong>
Authors: Mohammad Khosroshahi, Zahra Ebrahimi Khosfi, Azadeh Gohardoust, Sakineh Lotfi Nasab Asl, Fatemeh Dargahian, Leila Kashi Zanouzi
Publication Year: 2020
Published In: Desert Management Journal<\/p>

Summary<\/strong>:
The main aim of this research is to study the changes in the Gavkhouni Wetland over the past few decades and the potential role of dryness levels in intensifying dust storms in the surrounding areas. Results showed that during the hydrological year 1993-1994, about 89% of the wetland’s surface was water-covered. However, thereafter, the wetland has been undergoing a continuous drying trend; so much so that in the hydrological year 2012-2013, the water-covered surface dropped to less than 10%. From that year until 2018-2019, the wetland remained completely dry.<\/p>

Given the direction of the dust storms originating from the wetland, affecting Shahreza station during summer and Aghda station during autumn, the increasing trend of dust storms in these two areas during the mentioned seasons might be influenced by the recent drying levels of the wetland.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
