Sensitivity of meteorological-forcing resolution on hydrologic variables

Sensitivity of summer Lake Superior thermal structure to meteorological forcing

We use a one-dimensional model, forced with realistic meteorological measurements, to determine to first order the sensitivity of summer surface water temperature, heat content, and vertical stratification scale to three forcing variables: air temperature, wind speed, and previous winter ice cover, all three of which have exhibited long-term trends over the last few decades. Summer-averaged sur...

Meteorological Variables Associated with Stroke

To elucidate relationships between meteorological variables and incidence of stroke, we studied patients diagnosed with stroke after presenting to the emergency department (May 1, 2010-August 8, 2011). Patient demographics and medical data were reviewed retrospectively with regional meteorological data. Across 467 days, 134 stroke events were recorded on 114 days. On stroke days, maximum temper...

A study on DEM-derived primary topographic attributes for hydrologic applications: Sensitivity to elevation data resolution

Primary topographic attributes play a critical role in determining watershed hydrologic characteristics for water resources modeling with raster-based digital elevation models (DEM). The effects of DEM resolution on a set of important topographic derivatives are examined in this study, including slope, upslope contributing area, flow length and watershed area. The focus of the study is on how s...

On the Sensitivity Analysis of Two Hydrologic Models

The development of new hydrological models and the enhancement of the existing models are needed for water management. For instance, increasing rainfall may accelerate water erosion in watersheds and raise the probability of flooding events in the urban areas. The impacts include environmental and social-economic conditions. The hydrologic models SEADS, a physical process based model and GURUH,...
