This research studies different hydrological models in the catchments with various climates in the USA, and MODIS snow cover maps are introduced to assess and improve the models. In this research, assessment of the value of MODIS snow cover data in the hydrological modeling process is the main objective. Nine MOPEX catchments in the continental...

The stress on water supply systems is increasing, among others due to pollution, increasing demands, source depletion and climate change. More sustainable solutions with respect to water supply will decrease the stress. Rainwater harvesting can be one of these sustainable solutions. Depending on the characteristics of the rainwater harvesting...

The objective of this study is to improve the simulation of deep groundwater levels by time se- ries models with pre-defined impulse response functions. This is attempted by adding a conceptual non-linear root zone model to simulate the recharge series to the model and by testing the use of a separate response function for the percolation zone....

Hydrological models are used for several purposes, from reservoir management to stormflow prediction. However, their predictive power is often questionable. As most rainfall-runoff models are highly dependent on calibration, models often show deteriorated performance during the validation period. This is caused by too much focus on and trust in...

This study explores the possibility of calibrating a conceptual hydrological model to tracer (Oxygen-18) data measured in streamflow with the ultimate goal to predict discharge. The hypothesis is that (changes in) Oxygen-18 concentrations in the stream should tell something about the relative contribution of fast runoff compared to slow runoff ...

A common practice for hydrologists to determine the performance of a hydrological model and its parameter values, is by calibrating the model parameters on observed discharge data, but this data is not always available. For this reason, other data should be used as complementary data in order to reduce the uncertainty of outflow and processes in...

Direct measurement of river discharge is time consuming and financially demanding. Continuous river discharge measurements are therefore generally derived from continuous stage measurements, through a stage-discharge relation, also called a rating curve. Rating curves are determined by fitting a curve to a limited number of points (hi, Qi),...

The bulk of catchment science literature consist of ‘unique’ case studies describing the complex interaction of soils, water, vegetation, topography and geology at individual sites. Yet, the uniqueness of individual sites makes it difficult to transfer findings to new locations and facilitate understanding and prediction in other catchments. In...
