Hydrology Days has been held on the campus of Colorado State University each year since 1981. Hydrology Days is a unique celebration of multi-disciplinary hydrologic science and its closely related disciplines. The Hydrology Days vision is to provide an annual forum for outstanding scientists, professionals and students involved in basic and applied research on all aspects of water to share ideas, problems, analyses and solutions. The focus includes the water cycle and its interactions with land surface, atmospheric, ecosystem, economic and political processes, and all aspects of water resources engineering, management and policy.


  • Hydrology Days Award Session:  To be announced

  • Borland Lecture in Hydrology Session:  To be announced

  • Borland Lecture in Hydraulics Session: To be announced

  • Measuring and Modeling the Mountain Snowpack

With 50 to 80% of the water in the Western U.S. originating from snowmelt, it is imperative to accurately measure montane snowpacks, and model accumulation and ablation patterns and the resultant streamflow. This session will present the state-of-the-art science in measuring and modeling in rugged mountain environments.  

  • Emerging Contaminants

Papers are invited that characterize the behavior of emerging contaminants in the environment. These include pharmaceuticals, personal care products, biological agents, and other contaminants for which a fundamental understanding is needed in order to develop appropriate treatment and mitigation strategies.

  • Land Use Change and Streams
  • Nutrient Dynamics in Alluvial Streams
  • Biocomplexity

Papers are invited adressing the development of analyticaland observational tools needed to understand and predict the interactions and feedbacks among humans and aquatic species across complex landscapes.

  • Monitoring and modeling pollution and water quality in irrigated stream-aquifer systems

    Papers are invited that deal with actual data collection as well as development and application of models that address water quality in ground water and in rivers mainly as non-point sources derived from irrigation activities. Topics could include: issues with salinity, nitrates and phosphates, selenium, and other trace elements. Of special interest would be papers dealing with the development of mitigation strategies.

  • Latest technologies for estimating evaporation and evapotranspiration in the field

    Papers are invited that deal with data collection and analysis using some of the following approaches: lysimeters; water and energy flux measurements; estimates derived from bowen ratio or eddy-covariance towers, and the thermal infrared band from satellite imagery. Emphasis will be placed on the actual implementation of these methodologies for spatiotemporal quantification of evaporation and evapotranspiration in the field.

  • Experimental Methods in Sub-surface Investigations
  • Groundwater Remediation - focusing on advancements in groundwater remediation technologies
  • Transport in Porous Media - focusing on fate and behavior of contaminants in subsurface environments
  • Ground water-Surface water conjunctive management
  • Semi-arid region vadose zone hydrology and contaminant transport
  • Scaling issues: scale dependence and scale invariance in hydrology

  • Morphodynamics

  • Detecting and Modeling Climate Variability and Change Using Stochastic Approaches
  • Stochastic Techniques in Water Resources Planning and Management


Papers are welcome on all topics in hydrology and hydrology-related fields of science and engineering. Several sessions under consideration are:

  • Hydrologic dynamics and ecosystem structure

  • Eco-hydrology

  • Scaling issues: scale dependence and scale invariance in hydrology

  • Land surface-atmosphere interactions

  • Environmental river mechanics

  • Dynamics of droughts

  • Advances in river restoration

  • Fluvial geomorphology and landscape evolution

  • Environmental hydrogeology

  • Transport and coupled processes in the vadose zone

  • Nonlinear dynamics and multiple scale processes in hydrology

  • Coupled hydrologic, ecologic and atmospheric modeling

  • Groundwater and surface water interaction

  • Wetlands

  • Regional scale dynamics of soil moisture processes

  • Hydrological, fisheries, economic and social impacts of dam removal.

  • Modeling reservoir operations with biological constraints.

  • Quantifying hydrological needs of endangered species.

  • Role of hydrologic models in the TMDL process.

  • Applications of GIS in hydrology.

  • Measurements and estimation of aquifer recharge in large basins.

  • Estimation of hydraulic properties of porous media.

  • Multi-phase flow in heterogeneous porous media.

  • Statistical analysis of water quality data: are 'standard' methods
    evolving for specific management information purposes?

  • New methodological developments in stochastic hydrology

  • Water pricing

  • Water policy

  • Agricultural hydrology for irrigated crop production

The Conference will be held at Colorado State University in Fort Collins, Colorado. Fort Collins  http://www.ci.fort-collins.co.us is a community of more than 100,000 located 65 miles (104 kilometers) north of Denver. At an elevation of 5,000 feet (1,525 meters), it rests at the foot of the Rocky Mountains. Fort Collins is within an hour of several mountain parks including Rocky Mountain National Park, Roosevelt National Forest, and Lory State Park. Fort Collins enjoys a sunny, dry climate year-round. We encourage you to use your time in Colorado for recreation as well as technical learning.

The Hilton Fort Collins Hotel is located across from campus. Also the Best Western University Inn is located at the edge of campus. For additional lodging information, please browse the following URL: http://www.ftcollins.com/Default.asp
