Sixteen reservoirs which will not be used for irrigation are preserved for the purpose of environmental conservation in the benefit area of the public works of farm land consolidation constructed in the Isawa area in southern Iwate. In order to manage the reservoir with such background, it is important to understand in advance the actual condition of the budget of heat and water which have an indivisible relation.
Observation of hydrological and meteorological elements was carried out at Hoonoki reservoir from May to Oct. in 2006, of the previous year when the farmland consolidation around the reservoir was constructed. The observation results clarified the budget of heat and water of the reservoir, and suggested that formation of the water temperature environment of the reservoir was characterized with a large volume of inflow water.
