Evaluating the stormwater management model to improve urban water allocation system in drought conditions

Improving the urban water allocation system has depended on different technical and managerial components. One of the main solutions for increasing the available capacity is the predetermined plan for constructing a water circulation system to restore the existing water resources. For this objective, a combination model was conducted based on a stormwater management technique and environment landscape system (ELS) under drought conditions. A hydrological framework was established using the long-term meteorological information in central China to estimate the extreme values of surface water in each stress period. A data analysis system was generated at three meteorological points of the study area and the developed model was incorporated to simulate the behavior of the subsurface flow. Consequently, a growth simulation model was designed according to the soil structure and vegetation canopy cover to formulate a real-time plan for the restoration of ELS. Results showed that the proposed model could improve the water productivity in urban and environment consumptions. Furthermore, technical analysis confirmed the suitability and applicability of the developed plan in cities with water shortages.
