1837. aasta kevadine suurvesi Lätis ja Eestis ajaloolise hüdroloogia vaatenurgast. (Estonian)

THE SPRING FLOOD OF 1837 IN LATVIA AND ESTONIA FROM THE PERSPECTIVE OF HISTORICAL HYDROLOGY. (English)

In Estonia and Latvia, the examination of the hydrological regime of inland water bodies has traditionally fallen within the purview of the natural sciences, relying heavily on meteorological measurement data. Systematic weather observations commenced in the mid-19th century, significantly influencing the temporal scope of scientific investigations. However, it is worth noting that systematic measurement data, stretching as far back as 1795 in the case of Riga, has been a valuable resource for Latvian researchers. Regrettably, Estonia lacks such a chronologically consistent dataset. The Latvian scientific community's interest in the study of hydro regime is firmly grounded. The Daugava River, historically pivotal for Latvia, has undeniably shaped its social life, a fact that persists in various aspects even today. Latvia boasts a profusion of rivers; for instance, the Lielupe River and its tributaries wield considerable environmental influence on the societal fabric. Although the Estonian rivers exert a less pronounced impact through fluctuations in their water regime, their significance should not be dismissed. [ABSTRACT FROM AUTHOR]

Eestis ja Lätis on siseveekogude hüdroloogilise režiimi uurimine olnud loodusteadlaste pärusmaa ning toetunud mõõtmisandmetele. 19. sajandi keskpaigast kaugemasse minevikku minnes tuleb veerežiimi kõikumise uurimisel kasutada kirjalikke allikaid. Väina jõe veetaseme kõikumise kohta on olemas käepärane kronoloogiline käsitlus: kirjalikke ülestähendusi on kuni 1871. aastani. Sealt edasi on kasutada juba instrumentaalsed mõõtmisandmed. Üks katastroofiliseks uputuseks hinnatud suurvesi leidis Väinal aset 1837. aasta aprillis. Selle kohta, kas Lätis uputuse põhjustanud ilmaolud mõjutasid siseveekogude veerežiimi ka Eestis, seni ülevaadet pole. Küsimusele, kas suurvesi kimbutas ka Eesti ala, tuleb aga vastata jaatavalt. Tsaaririigi Liivimaa kubermangus tegutsenud sillakohtute Das Inlandis avaldatud materjalid näitavad selgesti, et suurvesi tõi endaga kaasa suurt varalist kahju, kuigi päevakajalisi ajakirjanduslikke kajastusi selle kohta samahästi kui pole.
