“…The sampling mesh size must also be taken into consideration together with the hydrographic network, the topography (Shahrestani and Mokhtari, 2017) and the climate (Montes-Avila et al, 2019) to study the spatial distribution of geochemical data. Moreover, the sediment grain size fraction is also an important parameter as metal content increases with decreasing grain size (MacKenzie and Pulford, 2002).…”

The processes of flooding and underflooding, observed during the overflow of closed reservoirs located in the conditions of a flat-depression flat terrain, may be the result of natural causes, when the incoming part of the water balance exceeds the outgoing part. In the case when the reservoir is flowing, the level rise is often associated with anthropogenic influence. In most cases, flooding processes are the result of a combination of causes, which in the general case can be natural and man-made. The correct choice of dewatering systems is possible only if the causes of waterlogging are precisely established. The article considers the consequences of flooding and underflooding of agricultural land (hayfields, pastures) of the “Tracts of Koshara” in the Tyukalinsky district, which is presumably associated with an increase in the level of Lake Saltaim - Tenis, regulated by a dam at the outlet of the Osha River (Ust-Logatka village) in Krutinsky area. In this regard, the purpose of the study is to determine the causes of flooding and the position of the boundaries of the zone of flooding of agricultural land in the Tyukalinsky district under conditions of an increase in the level of Lake Tenis.

Separation of geochemical anomalies from background is an important and essential issue in the exploration of mineral deposits. Statistical methods are used to separation of anomaly from background. Fractal/multifractal and singularity methods are very suitable for the separation of weak anomalies. For interpolation, various methods could be used such as most distance-weighting methods, kriging, spline interpolation, interpolating polynomials, and finite difference methods. This paper addressed application of multifractal techniques together with finite difference procedure to detect the anomalous regions. Fractal models such as concentration-area, spectrum-area, and singularity index model were selected to identify Pb-Zn anomalies. In this research, 170 samples from 33 boreholes were taken in the Haft-Savaran area and analyzed for determination of Pb-Zn anomaly. Singularity method was a suitable method for separating Pb and Zn anomalies. Also, the results showed that the geochemical anomaly has occurred along NE-SW trend and is consistent with the sulfide mineralization process and the faults of the region.
