تحليل الخصائص التصريفية والرسوبية لحوض وادي جولك شمال شرق كركوك

Abstract

Water scarcity is a serious problem in most dry and semi-arid lands, especially since the study area is devoid of a permanent watercourse. Settlers rely on groundwater for their agricultural activities, which may affect groundwater levels. To the inhabitants of these areas by studying seasonal runwaters to determine the size of the water revenue of the basin

The study started from the problem of the difficulty of predicting the water revenue and the seasonal output of seasonal runoff valleys, and the difficulty of extrapolating the most important hydrogeological factors affecting the formation of the basin and its hydrological response.

In order to determine the expected revenue of the basin, the following methods have been adopted:

- Analysis of the factors affecting the discharge of the basin.

- Analysis of the annual rate of discharge in Berkeley first, and the manner of delivery (KINROS) II.

- Analysis of the sedimentary load in a relational way, and the KINROS model.

     The study dealt with three topics, as well as the conclusions and recommendations. The first topic dealt with the philosophy of the subject, while the second topic focused on the factors influencing the discharge of the basin. The third topic dealt with the analysis of discharges and river loading.

    The study concluded with the following conclusions:

- The expected revenue rate in Berkeley, which was 0.67695 million / m3, was recorded in the wet year at 0.906521 million m 3, while in the dry year it decreased to 0.40695 million m3

- The KINEROS output shows that the upstream region in the eastern and northeastern regions is where the peak flow is due to the height factor and the peak flow values ​​of the basin ranged between 0.3-0.32 m3 / s.

- The results of KINEROS show that the production of sediments in the basin was concentrated in the upper parts of the basin east and west, in the upstream parts, indicating that the runoff is high in these areas, ranging between (0.01-9.58) kg / ha, Sedimentation begins in the middle of the basin, forming fertile areas suitable for cultivation.

      The main recommendations of the study are the need to build small dams on the main sewage of the basin. There is also a group of secondary basins characterized by high sedimentation products, which can be minimized and used to convert them into agricultural land for the purpose of storing water.
