| contents | Hydrological modeling of ungauged wadis in arid environments using GIS: a case study of Wadi Madoneh in Jordan Ali El Naqa Nezar Hammouri Ciencias de la Tierra Jordan rainfall runoff model Wadi Madoneh surface runoff Runoff is one of the most important hydrological variables used in most of the water resourcesapplications. Reliable prediction of runoff from land surface into streams and rivers is difficult and timeconsuming to obtain for ungauged basins. However, Remote Sensing (RS) and Geographic InformationSystem (GIS) technologies can augment to a great extent the conventional methods used in rainfall-runoffstudies. These techniques can be used to estimate the spatial variation of the hydrological parameters,which are useful as input to the rainfall-runoff models. The main objective of this study was to model therainfall-runoff process in a selected ungauged basin for the purpose of groundwater artificial recharge.This model simulation was carried out using an hydrological modeling system assisted by GIS. Twomodel runs were carried out using precipitation data of the Intensity-Duration-Frequency (IDF) curvesat Zarqa rainfall station for 10 years and 50 years return periods. With the first model run, the total directrunoff volume and the peak discharge for the 10 years return period were estimated to be 151,000 m3 and5.43m3/s, respectively. For the 50 years return period, the total direct runoff volume and the peak dischargewere estimated to be 280,000 m3 and 12.77m3/s, respectively. The model was optimized against observedrunoff data, measured during a storm event that occurred between the 2nd and the 4th of April, 2006.The flow comparison graph indicates that the calibrated model fits well with the observed runoff data,with a peak-weighted root mean square error (RMS) of less than 2%. This calibration was performed byapplying different curve numbers in the simulated model. It was possible to obtain a reasonable matchbetween the simulated and the observed hydrographs 2007 artículo científico 1026-8774 https://www.redalyc.org/articulo.oa?id=57224205 en http://www.redalyc.org/revista.oa?id=572 Revista Mexicana de Ciencias Geológicas application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Ciencias Geológicas (México) Num.2 Vol.24 |
