The Division of Water Resources carries out basic and applied research in hydrologic and water resources sciences and engineering including: irrigation and drainage, soil and groundwater, surface hydrology, ground-surface-atmosphere interactions, and their integrated water resources and waste water management. In more detail:
- The emphasis in Irrigation and Drainage focuses in field and laboratory studies to develop understanding of the processes concerning irrigated agriculture, irrigation scheduling and plant responses, improved irrigation and overall reclamation practices, state of the art irrigation systems operation and maintenance, irrigation structures and flow measuring devices, automation of irrigation systems, drainage and drainage engineering.
- The emphasis in Soil and Groundwater includes the dynamics of soil moisture processes, variability of hydraulic properties of soils, analysis and modeling of multiphase flow through porous media, infiltration, modeling of groundwater flow, analysis and modeling of hydrogeological processes, contaminant transport in the unsaturated and saturated zones, water quality and environmental hydrogeology.
- The emphasis in Physical Hydrology concentrates on, evapotranspiration processes, atmosphere-plant interfaces, micro-meteorology, the application of physical, stochastic, techniques for forecasting of precipitation, field measurements and data acquisition methodologies, determination of water use by plants using both in situ and remote sensing methods and real time data management.
- The emphasis in Surface Hydrology includes the analysis and modeling of hydrological processes such as precipitation, stream flow, and surface water storage at various temporal and spatial scales, land-surface atmosphere interaction, environmental hydrology, watershed modeling, and statistical/stochastic hydrology.
- The emphasis in Hydraulics includes fluid mechanics, flow in open and closed conduits, streamflow, reservoir levels, and groundwater levels, systems computing engineering design of agricultural hydraulic structures, design of small surface and groundwater reservoir systems, and design of surface and groundwater gauging network systems.
- The emphasis in Integrated Water Resources Management provides the linkage among hydrology, hydraulics, and environmental engineering, with interdisciplinary relation to economics, water law, social and natural science, computer science, and decision science. The decision-making focus on the application of advanced computer technology, decision support systems, GIS, and artificial intelligence to water resources and environmental systems. These tools are applied to complex multiple objective problems requiring coordinated planning and management, operation and maintenance of water infrastructure, risk and uncertainty management in water and environmental systems, forecasting and mitigation of extreme events such as floods and droughts, conjunctive use of groundwater and surface water, irrigation- hydropower tradeoffs, wastewater including recycle and reuse technologies management, integrated river basin management, hydrologic, environmental, and socioeconomic impact assessments of climate variability and stresses.
