تصميم السدود المائية باستخدام مستخلصات المعلومات الهيدرولوجية : دراسة تطبيقية

الملخص EN

Facing engineering and natural for the design of dams in the areas of dry valleys in Iraq, many difficulties, especially as regards the collection of hydrological information, as characterized by these areas the lack of information or difficulty in obtaining them, the most important information regarding the assessment and calculation of amounts of rain and sizes of water flows (floods) in the valleys.

Emerged in recent years, many new technologies that have helped in obtaining the required information more accurately and in a relatively short time and automatically.

We have learned in this study of the most modern technologies (geographic information systems GIS) in the treatment of digital elevation models (DEM), and determine the spatial distribution of rain.

As well as take advantage of the digital elevation models produced in determining the boundaries of water basins, valleys and streams network, and calculate hydrological variables such as time of concentration (time of concentration).

And the time interval (time lag).

Also benefit from satellite images and their role in the extraction of soil quality and land cover, and calculate the values of flow curves and values of the cold ground and the initial selection of the proposed dam sites.

And also take advantage of the software in the field of hydrological modeling, and some methods of automatic calibration and how to use them.
