Assessment of the hydroecological state of water bodies in the Maly Salgir River basin
Abstract
The integrated hydroecological research is especially relevant and actual for waterstressed regions, such as the Republic of Crimea. The purpose of the study is to use the example of the Maly Salgir River basin to make a comprehensive assessment of the hydroecological situation and develop a list of measures aimed at the rational use of its water resource potential. The studies were carried out in 2017–2019 and included visual observations of water bodies, measuring water discharges, studying chemical composition of water, calculation of water pollution index, assessment of water suitability for irrigation purposes, study of water toxicity and water balance calculation. The main pollutants of water resources are sulphates, phosphates and heavy metals (Cu, Cd, Pb, Zn). The quality of river water according to the WPI (water pollution index) varied from grade II "clean" to grade VI "very dirty", while the quality of channel ponds water was from grade II to grade IV "contaminated". Water balance calculations showed no water scarcity, as well as the possibility of additional water withdrawal for regular irrigation. Among the priority environmental measures there are the need for sewerage of villages located in the river basin, the inclusion of ponds that do not have inventory numbers in the state water register and the accounting of water resources use by the population.
