[328 08-0072] Leh and Chaubey comparison of two GIS-based approaches to hillslope runoff generation: a topographic index model and a likelihood indicator model.

[329 08-0063] Miller et al. perform a series of drought simulations for the California Central Valley for a range of droughts from mild to severe for time periods lasting up to 60 years.

[330 08-0036] Smiley et al., noting protocols designed for monitoring studies are not appropriate for impact assessments, develop guiding principles for designing impact assessments of ecological responses to conservation practices.

[331 08-0068] Larson examines public attitudes about an array of resource management efforts in Portland, Oregon. She outlines a conceptual approach for future assessments of environmental attitudes in particular settings while highlighting important value-based dimensions of judgments.

[335 08-0173] Zhang and Srinivasan explore a number of spatial interpolation techniques applied to aerial estimation of precipitation in a study area in China. Their results suggest advanced geostatistics methods that incorporate auxiliary information improve spatial precipitation estimation for hydrologic models.

[337 08-0106] Pure et al. use the SPARROW model to explore watershed and hydrological characteristics as the probable sources and delivery mechanisms of waterborne pathogens and their indicator (E. coli) in Guadalupe and San Antonio River basins in Texas.

[338 08-0119] Golden et al. report on nitrate sampling in mixed land cover watersheds draining to Cayuga Lake. They found a high degree of spatial heterogeneity in catchment response.

[340 08-0050] Schwede et al. present the Watershed Deposition Tool (WDT), an important tool for providing the linkage between air and water-quality modeling needed for determining the Total Maximum Daily Load (TMDL) and for analyzing related nonpoint-source impacts on watersheds.

[344 08-0016] Asleson et al. describe the development and evaluation of three approaches for performance assessment of rain gardens: visual inspection, infiltration rate testing, and synthetic drawdown testing. They found a combination of visual inspection and infiltration rate testing is particularly useful for developing maintenance tasks and schedules.
