Role of Watershed Management Practices on Flood Hydrograph Characteristics (Case Study: Kakhk Paired Watershed)
In the present study, the impact of watershed management practices on flood hydrograph characteristics was investigated using HEC-HMS model. In order to design, calibrate, and validate the model, data from a representative paired watershed (Kakhk Watershed, Khorasan Razavi Province, Iran) was collected and field surveys were performed to have the dataset further completed. Results of paired sam...
متن کاملImpact of Watershed Management activities on flood hydrograph Using HEC-HMS Model (Case Study: Ramyan Watershed)
Increasing the use of water and soil resources in watershed in recent years and unproductive and inappropriate use of land ecology has exacerbated the occurrence of floods. In this context, watershed management is one of the most effective ways to cope with this crisis. This research quantify the results of these activities by calculating the decreased volume and discharge due to biomechanical ...
متن کاملtechnical and legal parameters for determination of river boundary,( case study haraz river)
چکیده با توسعه شهر نشینی و دخل و تصرف غیر مجاز در حریم رودخانه ها خسارات زیادی به رودخانه و محیط زیست اطراف آن وارده می شود. در حال حاضر بر اساس آئین نامه اصلاح شده بستر و حریم رودخانه ها، حریم کمی رودخانه که بلافاصله پس از بستر قرار می گیرد از 1 تا20 متر از منتهی الیه طرفین بستر رودخانه تعیین، که مقدار دقیق آن در هر بازه از رودخانه مشخص نیست. در کشورهای دیگر روشهای متفاوتی من جمله: درصد ریسک...
15 صفحه اولFlood Hydrograph Estimation Using Watershed Bounded Network Model
Storage routing models are becoming more widely accepted for flood hydrograph synthesis. The network models represent a considerable advance in this direction even though these models are based on many assumptions and empirical relationships. Watershed Bounded Network Model (WBNM) is one such model. This model maintains a good relationship between the hydrological and geomorphological propertie...
متن کاملWatershed hydrograph model based on surface flow diffusion
[1] Based on the diffusion equation and Darcy’s law, Criss and Winston (2008b) developed the one-parameter analytical subsurface flow diffusion hydrograph model to represent the theory of rapid displacement of ‘‘old’’ aquifer water and shallow pore water following rainfall events. We developed a two-parameter analytical surface flow diffusion hydrograph model for urban or other basins that gene...
