Abstract
Throughout the world, many areas are facing serious challenges in field of water resources management. Implementation of water resources development projects has also numerous environmental effects such as disturbance of natural streamflow and decreasing downstream flowrate. Thus, estimating environmental requirements in downstream aquatic ecosystems have special importance. On the other hand, the allocation of limited water resources, water quality concerns, planning due to different climates, uncertainties, need to develop and applying different strategies for using water in sustainable conditions are the most important concerns from the view point of planners. Thus, the aim of performing this thesis is modeling water resources system and water consumption in Gorganroud river basin with environmental aspect. The mentioned system has changed due to human activities such as construction of dams, withdrawal of aquifers, as well as droughts and hydrological events. in the present study, regarding available data and specified targets, hydrological methods are used for evaluating river flow in downstream to satisfy environmental requirements. To simulate water management and planning in the basin there are several models among which WEAP software was chosen. Gorganroud basin in Golestan province was selected for case study. In this regard, at first the basin was simulated and then the model was performed for the basic condition and three different scenarios. In assumptions and criteria used in modeling 30-year period considered (1361-62 to 1391-92) and calculation carried out based on the monthly amounts. The results showed that environmental requirements obtained by 7Q10 method compared with other methods underestimates the requirements in all of the months. Furthermore, Thiesman method compared with other methods overestimates the environmental requirements in warmer months of the year, and in the other months Q90 method overestimates. Based on the simulated scenarios only environmental requirements obtained by 7Q10 method can supply predicted requirements for dams and direct withdrawals from basin. As well as the agricultural requirements, industrial requirements in all of the scenarios except 7Q10 cannot be completely provided and therefor have a significant shortage. The 7Q10 scenario has a 12% shortage which somehow is allowed.
