| Popis: | Active development of channel pits has begun with the aim of extracting nonmetallic building materials for the construction of cities and towns. When developing open pits, violations and non-fulfillment of compensatory measures in the river bed are possible. As a result of nonfulfillment of these measures, changes in the level regime of the river occur. All these actions lead to disastrous consequences. Therefore, the article considers the section of the Tom River. In its channel it is planned to develop a quarry of nonmetallic building materials. For the section of the quarry, the landing of the water level was determined, through a change in the slope of the free surface and the total drop in the water level. the change in flow rates in the everyday state was analyzed, development of the open pit was taken into account. To visually display the depth of the open pit, a matrix of heights was formed at the site of the Popadeykin deposit of sand and gravel materials. Based on the elevation matrix, a 3-D model of the pit was built, both before and after dredging. According to the data obtained, a possible change in speeds after the development of a quarry was predicted in comparison with domestic ones. The intervals of the velocity of the eroding and non-eroding flow were calculated. |
