The Department of “Hydrology of Land and Water Resources” was formed in 1953.
From the first year of its foundation up to 1985 the department was headed by distinguished scientist-hydrologist, doctor of geography, Professor Rustamov Saleh Haji oghlu.
Within the 1952-1956 under his leadership and direct his participation was studied the geographical peculiarities of all rivers of Azerbaijan, found their attraction in the four volumed monographs. Later on, studying the regularity of formation water flow and sediment, their distribution according to the time and space, on the basis of complex peculiarities of them was given the division into regions of the territory of Azerbaijan.
Since 1963 together with candidate of geographical sciences R.M. Gashgay he was carried out the researches on water balance and water resources of the republic.
From 1986 the head of department is doctor of geographical sciences R.M. Gashgay.
Since 2009 the department is named “Hydrology of Land and Water Resources”.
DIRECTIONS OF RESEARCHES AND THEMES
The basic direction - surface waters, study of the formation and passing of water flows and sediments in different physic-geographical conditions, determination of water balance and water resources, revealing the influence of economical activities on river flows, study of hydrodynamic peculiarities of the formation of floods and mud streams, resources conservation and protection of water resources.
Studies of lakes and reservoirs, estimation of chemical and ion flow of the rivers.
MAIN SCIENTIFIC RESULTS AND ACHIEVEMENTS
Studied the regularities of formation and passing of mountain river flows, suggested the methods of determination of underground flow of the rivers for unstudied rivers and compiled a map of their element.
On the basis of their was obtained the interrelation of elements of water balance for mountainous countries for the first time, determined the water resources of landscape belts, river basins and all republic as a whole.
It was determined that the transit flow of water resources of Azerbaijan consist of 30,9 km3, but local – 10,3 km3, suggested the methods for determination of summer natural regulation of flow.
Studied the influence of economical activities on river flows and ecological state of the lower parts of watersheds, determined that the water resources did not decrease, but took place their distribution on the territory.
Studied the peculiarity of formation of solid flow and suspended sediments and suggested the methods of their calculation.
For the first time it was determined that in connection with changes of ecological conditions of the territory of Lenkaran natural region and increasing of middle layer of wash off from surface of watersheds takes place the intensification of desertification processes.
Worked out the methods of calculation of ion flow, biogenic and organic elements, given the estimation of intensity of chemical denudation and carried out the classification of waters according to their content.
Studied the hydrological peculiarities of lakes and reservoirs and their becoming silted.
Now employees of a department continue work on researches of influence of the anthropogenous factor on a drain of the rivers and ecological conditions of their reservoirs.
