Hydrology as a science

RESEARCH METHODS.

In hydrology, research methods such as stationary, expeditionary and experimental-laboratory are used. In the stationary method, the elements of the hydrological regime of water bodies are monitored regularly over the years.
In the rivers, lakes, reservoirs and glaciers of the country, this work is carried out mainly at the hydrological stations and posts of the Center for Hydrometeorological Service under the Cabinet of Ministers of the Republic of Uzbekistan (Uzhydromet).
In the expedition method, water bodies in a particular area are studied in a field setting in general or for a specific purpose. Every year, special expeditions are organized in the system of Uzhydromet, the Ministry of Agriculture and Water Resources, the Academy of Sciences and other network institutions.
The experimental-laboratory method allows to determine the natural and chemical properties of water, to study hydrodynamic phenomena and other processes under modeling conditions. The experiments are carried out in laboratories equipped with special equipment and devices.

4. TADQIQOT USULLARI.
Gidrologiyada statsionar, ekspeditsiya va eksperimental-laboratoriya kabi tadqiqot usullari qo'llaniladi. Statsionar usulda suv ob'ektlarining gidrologik rejimining elementlari yillar davomida muntazam ravishda nazorat qilinadi.
Respublikamiz daryolari, ko‘llari, suv omborlari va muzliklarida bu ishlar asosan O‘zbekiston Respublikasi Vazirlar Mahkamasi huzuridagi Gidrometeorologiya xizmati markazining (O‘zgidromet) gidrologik stansiyalari va postlarida amalga oshiriladi.
Ekspeditsiya usulida maʼlum hududdagi suv obʼyektlari umumiy yoki muayyan maqsadda dala sharoitida oʻrganiladi. Har yili O‘zgidromet tizimi, Qishloq va suv xo‘jaligi vazirligi, Fanlar akademiyasi va boshqa tarmoq muassasalarida maxsus ekspeditsiyalar tashkil etilmoqda.
Tajriba-laboratoriya usuli suvning tabiiy va kimyoviy xossalarini aniqlash, gidrodinamik hodisalar va boshqa jarayonlarni modellashtirish sharoitida o‘rganish imkonini beradi. Tajribalar maxsus jihozlar va asboblar bilan jihozlangan laboratoriyalarda olib boriladi.
