Purpose: to develop an algorithm for assessing the local runoff water resource potential from gully-ravine watercourses adjacent to irrigation canals for their involvement in water use based on calculating the water balance and selecting recharge scenarios using the Azov Main Canal (MC) as an example.
Materials and methods. The information on the Azov irrigation system (IS) characteristics provided by the Rostovmeliovodkhoz Administration, the data of our own geodetic surveys and Earth's remote sensing were used. The hydrological characteristics were determined by processing ground-penetrating radar survey data with geoinformation system tools.
Results and discussion. A block diagram of the developed algorithm and an example of its operation are provided. The Azov Main Canal is adjacent to 7 ravines (Talovaya, Semisotnaya, Tushina, Vorovskaya, Arpachinskaya, Sukhoi Batay and Mokry Batay), at the intersection with which the canal is provided with 7 siphons. The ravine maximum annual runoff volume can reach 2.3–7.7 million m³ depending on the percentage provision year (P = 50, 75 and 95 %). The ravines Talovaya (24.7 %), Sukhoi (19.8 %) and Mokry Batay (32.3 %) have the greatest water potential. About 70 % of the annual runoff occurs during the period from November to March, when the MC is not functioning.
Conclusions. In order to involve local runoff water resources as an additional source of supply for the Azov IS, the following is recommended: the construction of diversion canals on the Talovaya and Sukhoi Batay ravines upstream of the intersection of watercourses with the MC for gravity filling of the MC; the use of the pond at the Mokry Batay ravine as a storage pond using mobile pumping stations for pumping water into the canal. The algorithms and scenarios described in this article can be used to integrate local runoff into existing water systems, especially in areas with surface water shortages and during the reconstruction of main canals.
