a comparison of degree-day and radiation base of snowmelt runoff model (srm)
in highland watersheds, runoff generated by snow melting plays an important role in stream water supply. srm (snowmelt runoff model) is a hydrologic model which simulates and predicts daily flow in mountain watersheds dominated by snow melting process. the srm is based on the degree-day procedure which, is a widely used method but does not consider physical factors. in the current research, the...
متن کاملEstimating degree-day factors from MODIS for snowmelt runoff modeling
Degree-day factors are widely used to estimate snowmelt runoff in operational hydrological models. Usually, they are calibrated on observed runoff, and sometimes on satellite snow cover data. In this paper, we propose a new method for estimating the snowmelt degree-day factor (DDFS) directly from MODIS snow covered area (SCA) and ground-based snow depth data without calibration. Subcatchment sn...
متن کاملUsing Satellite Images and Srm Hydrological Model for Evaluating Runoff Resulting from Snowmelt in Navrood Basin
Original scientific paper Determining snowmelt runoff share of watershed basins with snow and wet snow regimes is one of the main concerns of the experts in water resources field, assessment of which has been done so far with difficulties and high rate of error due to lack of snow survey and weather stations in highlands of basin and use of traditional surveying methods. Lack of integrated mana...
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...
متن کاملsimulation of snowmelt runoff using srm model and comparison with neural networks ann and anfis (case study: kardeh dam basin)
introduction: snowmelt runoff plays an important role in providing water and agricultural resources, especially in mountainous areas. there are different methods to simulate the process of snowmelt. inter alia, degree-day model, based on temperature-index is more cited. snowmelt runoff model is a conceptual hydrological model to simulate and predict the daily flow of rivers in the mountainous b...
