Description: Climate change has impact on various hydrologic variable including temperature and precipitation regimes. In temperate and humid regions like southern Ontario, the effects of climate change on hydrologic variables are unique. The average annual temperature is going up, but the extreme increase is in the minimum winter temperature. Winter average temperature has gone up by about 2oC over the last 70 years. However, extreme daily minimum temperature has gone up by more than 3oC. These climate effects have great impact on agricultural water management due to change in the nature of precipitation and possible length of growing season (frost-free days). The snowfall over winter months is decreasing and the rainfall is increasing. The number of frost-free days during late fall months, early winter months, late winter months and early spring months are increasing. This is resulting in an increase in length of the growing season. This research focuses on the effect of change in hydrologic variables on agricultural water management in Ontario. The special attention is given to the impact on available surface water (stream flow, ground water recharge) quantity and water quality (soil erosion and sediment loads).
