changes in land use can significantly influence the hydrological cycle and hence affect water resources. understanding the impacts of land use changes on hydrology response at the watershed scale can facilitate development of sustainable water resources strategies. this paper investigates the hydrological effects of land use change in the zanjanroodbasinofiran, during last 40 years. the study r...

A major research challenge in ungauged basins is to quickly assess the dominant hydrological processes of watersheds. In this paper we present a top-down approach from first field reconnaissance to perceptual model development, model conceptualization, evaluation, rejection and eventually, to a more substantial field campaign to build upon the initial modeling. This approach led us from an init...

In this white paper, we will discuss the issue of data trust in hydrology, how data trust arises as a central theme in modeling hydrological objects, and what one can do to enable research by building trustcentered infrastructure. We will discuss how trust and distrust arise in practice. We will suggest a radical strategy for managing digital research data that solves perceived problems in hydr...

The potential of an artificial neural network to perform simple non-linear hydrological transformations is examined. Four neural network models were developed to emulate different facets of a recognised non-linear hydrological transformation equation that possessed a small number of variables and contained no temporal component. The 5 modeling process was based on a set of uniform random distri...

17 Remote sensing (RS) data are an alternative to in-situ hydrometeorological data in 18 remote and poorly monitored areas and are increasingly used in hydrological 19 modeling. This study presents a lumped, conceptual, river basin water balance 20 modeling approach based entirely on RS data: precipitation was obtained from the 21 Tropical Rainfall Measuring Mission (TRMM) Multisatellite Precip...

[1] In a previous study (Hasan et al., 2006) we applied time series analysis and distributed hydrological modeling techniques to investigate the effect of hydrological processes on observed terrestrial gravity residuals. In this study we apply terrestrial gravity observations (measured in one location) to constrain simple hydrological models in a catchment around the gravimeter. A superconducti...
