Local latitude is formed in the North-South with the beginning at characteristic 290 points at the source of the Irka River, the river itself is in a rectangle 23.89 minutes long (in latitude) and 18.89 minutes wide (in longitude). The starting point at the source of the river is given a zero rank. The purpose of the article is the analysis of asymmetric wavelets of changing one coordinate - local latitude reduced to the Irovka River from source to mouth. After identifying the universal wave equation, 25 terms were obtained in the form of asymmetric wavelets with variable amplitude and period of oscillation. All 25 wavelets are finite-dimensional, that is, each of them has a beginning and an end to oscillatory adaptation to changes in the structure of the channel topography. Moreover, a significant part of the oscillations occurs inside the small river Irovka with a total length of 69 km. The first three members together gave a correlation coefficient of 0.9099. This level of adequacy is more than 0.9 and the general three-term equation refers to the strongest factorial connection. The remaining 22 members further increase the level of adequacy almost to a correlation coefficient of 1. Analysis showed that the local latitude of the small river Irovka, as measured by satellite imagery, gives a high degree of certainty to quantization of the relief. Residues from the 25th term gave a high modeling error at the source of the river and at the first rank of the point. In summer, the riverbed dries upstream. Errors according to characteristic points of the channel were distributed as follows: 0 - 0.1% 95 pcs. (32.76%); 0 - 1.0% 262 pcs. (90.34%); from 0 to 5% 283 characteristic points of the channel, which is 97.59% of the total number of 290 points
