Since 1965 twenty-nine allotment and matching grant projects have been supported by the Nebraska Water Resources Research Institute. Topics studied range from ecological impact of surface water impoundments in the Great Plains to a simulation of the effects of dynamic water pricing policies. Current research subjects include: (1) water quality with emphasis on agricultural pollution and eutrophication; (2) analysis of water resources systems with particular consideration given to conjunctive use models, hydrologic system models, ecosystem models, irrigation system models, management models and sediment transport models; (3) evaporation and transpiration with emphasis on microclimate studies, evapotranspiration models, phreatophyte studies and water potential-plant response studies; (4) water law; and (5) urban water systems.
