Surface Water Supply

Optimal reservoir operation changes and adaptation strategies for the Zayandeh-Rud River Basin's surface water supply system are examined for a changing climate during the 2015–2044 period. On average, the monthly temperature in the basin is expected to increase by 0.46–0.76 °C and annual precipitation is expected to decrease by 14–38% with climate change, resulting in a reduction of the Zayandeh-Rud's peak stream flow and the amplitude of its seasonal range. Snowfall decrease in winter months will generally lead to an 8–43% reduction in annual stream flow under climate change. A reservoir operation model is developed and optimal reservoir operation strategies are identified for adaptation of the basin's surface water supply to climate change in the face of the increasing water demand. Results indicate that the reservoir drawdown season starts 2 months earlier under climate change. Smaller storage levels and greater water releases must occur to meet the increasing water demand. The optimized water release can provide sufficient water for non-agricultural water demand, but agriculture will experience more severe water shortage under a changing climate. Having the highest vulnerability, the agricultural sector should be the main focus of regional management plans to address the current water challenge and more severe water shortages under climate change.

Surface Water Supply

<p>The existing assessments of geodiversity are based on very different abiotic elements of the natural environment. This makes these assessments incomparable between different areas and obtained by different methods. Therefore, it is sometimes difficult to say in comparative studies which area is more or less geodiverse. The search for unambiguous geodiversity assessments is one of the most important challenges in the current era of climate change and environmental exploitation. This presentation aims to indicate those elements of the natural environment and their parameters that are independent of the specificity of the area being assessed. The specificity of the assessed area may vary in many aspects, e.g. genesis and provenance, age and evolution, hypsometry and geomorphometry, geology and lithology, soil and surface sediments, climate zones, groundwater and surface water supply, etc. Is it possible to find such variables that will be universal and objective in assessing geodiversity with such a variety of abiotic elements of the environment? During the presentation, an attempt will be made to answer the above question. The suggestion of this answer should be a contribution to the discussion on the scope of the standard variables influencing geodiversity.</p>
