A stochastic nonparametric technique for space‐time disaggregation of streamflows
TLDR
We present a K-nearest-neighbor approach to resample monthly flows conditioned on an annual value in a temporal disaggregation or multiple upstream locations conditioned on a downstream location for a spatial disaggregation. Expand

A nonparametric stochastic approach for multisite disaggregation of annual to daily streamflow
[1] Streamflow disaggregation techniques are used to distribute a single aggregate flow value to multiple sites in both space and time while preserving distributional statistics (i.e., mean,Expand

Modified K-NN Model for Stochastic Streamflow Simulation
This paper presents a lag-1 modified K-nearest neighbor K-NN approach for stochastic streamflow simulation. The simula- tion at any time t given the value at the time t1 involves two steps: 1Expand

The implications of climate change scenario selection for future streamflow projection in the Upper Colorado River Basin
The impact of projected 21st century climate conditions on streamflow in the Upper Colorado River Basin was estimated using a multi-model ensemble approach wherein the downscaled outputs of 112Expand

A stochastic nonparametric approach for streamflow generation combining observational and paleoreconstructed data
[1] The Colorado River basin experienced the worst drought on record during 2000–2004. Paleoreconstructions of streamflow for the preobservational period show droughts of greater magnitude andExpand

Mid-21st century projections in temperature extremes in the southern Colorado Rocky Mountains from regional climate models
This study analyzes mid-21st century projections of daily surface air minimum (Tmin) and maximum (Tmax) temperatures, by season and elevation, over the southern range of the Colorado Rocky Mountains.Expand

An enhanced nonparametric streamflow disaggregation model with genetic algorithm
TLDR
We review the underlying features of existing nonparametric disaggregation methods, identify some of their pros and cons, and propose a disaggregation algorithm that is capable of surmounting some of the shortcomings of the current models. Expand

Statistical Nonparametric Model for Natural Salt Estimation
Many rivers in the Western U.S. suffer from high salinity content due to both natural and human-induced causes. Computer simulation models are often used to estimate future salinity levels andExpand
