Numerous virulent and widespread diseases are related to water. The transmission and outbreak of water-related diseases are closely coupled to their hydrological environment. Changes in this environment and the associated hydrological processes may affect the occurrence and virulence of waterrelated diseases. Environmental changes can be manifold, including e.g. climate and land use, agricultur...

Rainfall-runoff models sometimes have to deal with hydrological systems for which the water balance cannot be closed without taking into account the relation between surface and groundwater. In this study we intend to clarify in which kind of situations surface hydrologists should worry about these relations. We also conduct a preliminary study about how underground exchanges could be integrate...

Minimum data length is vital to guarantee accuracy in hydrological analysis. In practice, it sometimes determined by the experiences of hydrologists, leading selection acceptable minimum an arguable issue among hydrologists. Therefore, this study aims investigate impact on parameter estimation and model performance, especially for data-scarce regions. Using four primary datasets from river basi...

In flood management it is important to reliably estimate the discharge in a river. Hydrologists use historic data to establish a rating curve – a relationship between the water level (stage) and discharge. ANN and M5 model trees were used to reconstruct this relationship on an example of an Indian river. The predictive accuracy of these machine learning methods models was found to be superior t...

The prediction of hydrological dynamics is an important issue in the scientific community of hydrologists and modellers and essential for integrated water resources decision support. However, the utilization of hydrological models in regions with no or a limited amount of measured data is restricted. Remote sensing techniques provide the means to derive such information, e.g. land cover or soil...

Scientific workflows (SWF) are an emerging approach that enables scientists to compose and execute complex, distributed scientific processes. The approach is premised on the ability to compose, publish, share and reuse workflows across distributed communities of collaborating scientists. Scientific workflow software (SWFS) provides a technical framework to compose, publish, and reuse SWFs toget...

Establishment of rating curves are often required by the hydrologists for flow estimates in the streams, rivers etc. Measurement of discharge in a river is a time-consuming, expensive, and difficult process and the conventional approach of regression analysis of stage-discharge relation does not provide encouraging results especially during the floods.
