چکیده
. در این تحقبق به بررسی اثر پارامترهای فیزیوگرافی مانند مساحت حوضه، محیط حوضه، شیب متوسط حوضه، شیب متوسط رودخانه، طول رودخانه و ارتفاع متوسط حوضه بر راندمان سدهای تاخیری پرداخته شد و سعی گردید تا با معرفی حساسترین پارامترها محدوده ای مناسب برای احداث سدهای تاخیری تعیین و بر اساس آن محل بهینه سد تاخیری مشخص شود. ضمنا سعی شدتا به یک معادله عمومی بین راندمان و ضرایب شکل و گراویلیوس حوضه آبریز دست یافت تا بتوان با در دست داشتن ضریب گراویلیوس و یا ضریب شکل حوضه آبریز بالادست سد تاخیری، به راندمان متناظر با آن محدوده دست پیدا کرد.

Hydrologic Modeling System (hec-hms):
Many cities have been built along large rivers. The rivers can provide a source of drinking water, act as receiving water for treated effluent, provide navigation for shipping, and other beneficial uses. However, the city must also be protected from flooding due to the close proximity to the river. Hydrologic analysis plays a crucial role in the development of plans for protecting a river city....
متن کاملGis-based Hydrological Modeling: a Comparative Study of Hec-hms and the Xinanjiang Model
The last few years have witnessed an enormous study in the area of integrated hydrological modeling with GIS application. In this research, attempt was made to critically look at the application of HEC-GeoHMS which is an extension of ArcView in HEC-HMS; an HEC package which is a new generation of software being developed for rainfall-runoff simulation. The main role of HEC-GeoHMS is to formulat...
متن کاملOn the Clark Unit Hydrograph Model of HEC-HMS
A mathematically correct form of the linear storage element’s routing equation is specified requiring only a slight modification of the existing HEC-HMS routine. The new formulation, unlike the current version in use, is unconditionally stable as long as the time step and the storage coefficient values are trivially specified as positive numbers.
متن کاملUse of HEC-RAS and HEC-HMS models with ArcView for hydrologic risk management
The paper discusses how the well known USACE HEC models, RAS and HMS, are fully integrated within the decision support system of the Romagna River Basins in order to predict flood effects. The models are fully available from the web and cope with such a variety of problems as rainfall-runoff modeling, river and civil works hydraulics, and the mapping of hydraulic hazard. The paper illustrates t...
متن کاملMAS Methodology for HMS
Developments in Holonic Manufacturing Systems (HMS) have been reported in three main areas: architectures, algorithms, and methodologies for HMS. Despite the advancements obtained in the first two areas the methodologies for HMS have not received great attention. To date, many of the developments in HMS have been conducted in an almost “empirical way”, without design methodology. There is a def...
متن کاملRunoff characteristics and application of HEC-HMS for modelling stormflow hydrograph in an oil palm catchment.
Rainfall-runoff processes in a small oil palm catchment (8.2 ha) in Johor, Malaysia were examined. Storm hydrographs show rapid responses to rainfall with a short time to peak. The estimated initial hydrologic loss for the oil palm catchment is 5 mm. Despite the low initial loss, the catchment exhibits a high proportion of baseflow, approximately 54% of the total runoff. On an event basis, the ...
