%0 Journal Article %T Remote Sensing in Hydrology %A Bahareh Qanati %A Javad Mohammadi %J specialty journal of civil engineering and environmental system %D 2019 %V 2 %N 1 %P 27-34 %X Hydrology is the scientific study of the occurrence, distribution, movement and the physical ‎and chemical properties of water, and its relationship with the living and material components ‎of the environment. Due to water scarcity, population growth, improved quality of life, ‎enhanced quality of healthcare, ever-increasing water consumption and food shortages in the ‎future decades, many countries will face a crisis, that there will be no promising solution for it. ‎Therefore, to investigate the various water resources and to monitor those parameters ‎influencing the hydrological cycle, those sensors capable of estimating different patterns of ‎these parameters are used. One of the most important applications of radar data is to use them ‎in hydrologic models. Those methods used for the estimation of hydrometeorological fluxes, ‎i.e. evapotranspiration and snowmelt runoff, are also described using these state variables. ‎Remote sensing is the process of deduction of surface parameters based on the measurement of ‎electromagnetic radiation upwelling from the Earth's surface. The present study focuses on ‎those applications of remote sensing that are more promising in hydrology in our belief. %U https://sciarena.com/article/remote-sensing-in-hydrology
