Determining Curve Number and Estimating Runoff Yield In HESARAK Catchment
The process of precipitation – runoff of each basin, is influenced by hydrologic, geomorphology conditions, geological formation and vegetation. There are different methods in drainage basins. One way to estimate the runoff height is Curve Number (CN) method. That reperesents the hydrological behavior of basin. data were collected for statistics of climate and then topographic map of 1: 25000 a...
متن کاملEstimating Height runoff by using curve number method and Arc- CN Runoff tool in Afjeh Catchment
In Iran, there is a general risk of runoff and flood, and since this country has a dry to semi-arid climate, its predominant rainfall is not evenly distributed in terms of time and place. Routine runoff at the earth's surface can lead to risks such as groundwater abatement, social issues such as population migration, erosion and loss of soil fertility, sedimentation in reservoirs and water q...
متن کاملApplication of NRCS-curve number method for runoff estimation in a mountainous watershed
The major problem in the assessment of relationships between rainfall and runoff occurs when a study is carried out in ungauged watersheds in the absence of hydro-climatic data. This study aims to evaluate the applicability of Natural Resources Conservation Service-Curve Number (NRCS-CN) method together with GIS in estimating runoff depth in a mountainous watershed. The study was carried out in...
متن کاملDynamic-Stochastic Model of Snowmelt Runoff Generation and Its Application for Estimating Extreme Floods
A coupling of a physically based model of snowmelt runoff generation with the Monte-Carlo simulation of the model inputs is applied. The model of runoff generation is based on the finiteelement schematization of river basin and includes the description of the following hydrological processes: snow cover formation and snowmelt, freezing and thawing of soil, vertical soil moisture transfer and in...
