This thesis applies several different remote sensing techniques to data collected from 2005 to 2007 on central Indiana reservoirs to determine the best performing algorithms in estimating the cyanobac...
Evaluation of alternative formulae for calculation of surface temperature in snowmelt models using frequency analysis of temperature observations
alternative formulae surface temperature snowmelt models frequency analysis temperature observations
font style='font-size:12px;'>
2010/4/7
The snow surface temperature is an important quantity in the snow energy balance, since it modulates the exchange of energy between the surface and the atmosphere as well as the conduction of energy i...
Estimation of the impact of short-term fluctuations in inputs on temporally aggregated outputs of process-oriented models
short-term fluctuations inputs outputs process-oriented models
font style='font-size:12px;'>
2009/12/4
Process-oriented models driven by highly resolved meteorological inputs and comprising a short internal time step are sometimes used to predict substance fluxes in air, soil and water over fairly long...
Use of regional climate model simulations as input for hydrological models for the Hindukush-Karakorum-Himalaya region
regional climate Hindukush-Karakorum-Himalaya region hydrological models
font style='font-size:12px;'>
2009/7/22
The most important climatological inputs required for the calibration and validation of hydrological models are temperature and precipitation that can be derived from observational records or alternat...
The accuracy of simple soil water models in climate forecasting
soil water models climate forecasting
font style='font-size:12px;'>
2009/6/8
Several simple soil water models with four layers or less, typical of those used in GCMS, are compared to a complex multilayered model. They are tested by applying a repeating wetting/drying cycle at ...
Coupling meteorological and hydrological models for flood forecasting
flood forecasting meteorological hydrological models
font style='font-size:12px;'>
2009/5/18
This paper deals with the problem of analysing the coupling of meteorological meso-scale quantitative precipitation forecasts with distributed rainfall-runoff models to extend the forecasting horizon....
Abrupt change in climate and climate models
climate changes warming
font style='font-size:12px;'>
2009/5/15
First, we review the evidence that abrupt climate changes have occurred in the past and then demonstrate that climate models have developing capacity to simulate many of these changes. In particular, ...
Technical Note：Updating procedure for flood forecasting with conceptual HBV-type models
flood forecasting conceptual HBV-type models rainfall-runoff model
font style='font-size:12px;'>
2009/5/15
Flood forecasting is of increasing importance as it comes to an increasing variability in global and local climates. But rainfall-runoff models are far from being perfect. In order to achieve a better...
Sensitivity analysis of Takagi-Sugeno-Kang rainfall-runoff fuzzy models
Sensitivity analysis rainfall-runoff fuzzy models

This paper describes the development and assessment of global 0.5° near-surface atmospheric data from 1948 to 2006 at daily (for precipitation, snowfall, and specific humidity) to 3-hourly (for temper...
simulation based approach for representation of rainfall uncertainty in conceptual rainfall runoff models
simulation extrapolation rainfall rainfall runoff models
font style='font-size:12px;'>
2009/4/13
One of the common contributors to the uncertainty in any rainfall runoff model is the error distribution within the rainfall inputs. The uncertain rainfall introduces systematic bias in the estimated ...
