Estimating 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 کاملRainfall-Runoff Modelling Using Genetic Programming
The problem of accurately determining river flows from rainfall, evaporation and other factors, occupies an important place in hydrology. The rainfall-runoff process is believed to be highly non-linear, time varying, spatially distributed and not easily described by simple models. Practitioners in water resources have embraced data-driven modelling approaches enthusiastically, as they are perce...
متن کاملUsing Empirical Relationships and Neural Network in GIS for Developing Rainfall-Runoff Model
SUMMARY The estimation of runoff volume from a catchment is required for planning and design of water resources projects such as the design of storage facilities, assessment of water available for municipal, agricultural or industrial purposes, etc. but proper planning is possible when the accuracy of hydrological process output would be sure. Simulation and prediction of runoff is very importa...
متن کاملNonparametric direct mapping of rainfall-runoff relationships: An alternative approach to data analysis and modeling?
[1] We present a new approach for the analysis and modeling of catchment rainfall-runoff relationships that uses as predictor variables input history summary variables only. The latter are defined as linear combinations of inputs at a given number of previous time steps. This transforms the dynamic identification problem into a static one. As the identification algorithm we use regression trees...
متن کاملSpatially distributed storm runoff depth estimation using Landsat images and GIS
The use of geographic information systems (GISs) and remote sensing to facilitate the estimation of runoff from watershed and agricultural fields has gained increasing attention in recent years. This is mainly due to the fact that rainfall-runoff models include both spatial and geomorphologic variations. The US Department of Agriculture, Natural Resources Conservation Service Curve Number (USDA...
