Water is the essential need for human beings, plants, agriculture as well as for the natural ecosystems. However, the advent of climate change and land use use development has substantial impact on the different components of hydrology creating a major challenge to maintain sustainable management of water resources. Therefore, the aim of our research is to understand the impacts of these stressors on watershed hydrology including precipitation, evapotranspiration, surface runoff, tile flow, infiltration, groundwater recharge, and streamflow. Then connecting these hydrology components such as surface runoff, tile flow, streamflow on sediment and nutrient transport on the landscape.

Water Quality Monitoring Water Quality Monitoring

Water is the fundamental necessity for human, plants, animals, and others to survive in this world. Yet we often neglect the quality of water whether in streams, rivers, lakes, or groundwater. Water quality monitoring plays crucial role in evaluating whether the water can be used safely for different purposes such as drinking, recreational, habitat, agriculture, industrial, and others. Climate change, rising food demand, and urbanization pose significant negative impact on water quality which has been observed throughout the world. For example, 500,000 residents in Toledo, Ohio were without safe drinking water for 72 hours from Lake Erie due to increased harmful algal blooms (HABs).  Therefore, water quality monitoring is essential to evaluate the standard of water quality for specific water use or verifying the impact of different conservation practices/ best management practices (BMPs) to improve water quality.

Irrigation plays critical role in producing enough food and agricultural commodities to rapid population growth and it contributes towards global food security. Changing precipitation pattern and increasing temperature due to climate change has altered the crop water requirement during the growing season resulting into alteration of agricultural production. To that end, research is required to inform policymakers and producers the impact of climate change on irrigation demand, crop water requirement, crop yields, water scarcity in the region.
