Determination of Spatially-Distributed Hydrological Ecosystem Services (HESS) in the Red River Delta Using a Calibrated SWAT Model

Hà, T.L. (author), Bastiaanssen, W.G.M. (author)

The principles of Integrated Water Resources Management (IWRM), conservation of natural capital, and water accounting requires Hydrological Eco-System Services (HESS) to be determined. This paper presents a modeling approach for quantifying the HESS framework using the Soil Water Assessment Tool (SWAT). SWAT was used–after calibration against...

Changes of hydro-meteorological trigger conditions for debris flows in a future alpine climate

Kaitna, Roland (author), Prenner, David (author), Switanek, Matt (author), Maraun, Douglas (author), Stoffel, Markus (author), Hrachowitz, M. (author)

Debris-flow activity is strongly controlled by hydro-meteorological trigger conditions, which are expected to change in a future climate. In this study we connect a regional hydro-meteorological susceptibility model for debris flows with climate projections until 2100 to assess changes of the frequency of critical trigger conditions for...

Towards more credible models in catchment hydrology to enhance hydrological process understanding: Preface

Refsgaard, Jens Christian (author), Mai, Juliane (author), Hrachowitz, M. (author), Jain, Sharad K. (author), Stisen, Simon (author)

Catchment modelling has undergone tremendous developments during the past decades. In the 1970s, the focus was on simulation of catchment runoff with process descriptions and data inputs being lumped to the catchment scale. Later developments included spatially distributed models allowing data inputs and hydrological processes to be simulated at...

Wannasin, C. (author), Brauer, C. C. (author), Uijlenhoet, R. (author), van Verseveld, W. J. (author), Weerts, A. H. (author)

Study region: Upper region of the Greater Chao Phraya River (GCPR) basin in Thailand. Study focus: The upper GCPR basin is highly regulated by multipurpose reservoirs, which obviously have altered the natural streamflow. Understanding quantitative effects of such alteration is crucial for effective water resource management. Therefore, this...

Do direct and inverse uncertainty assessment methods present the same results?

Ahmadi, Arman (author), Nasseri, M. (author)

Hydrological models are simplified imitations of natural and man-made water systems, and because of this simplification, always deal with inherent uncertainty. To develop more rigorous modeling procedures and to provide more reliable results, it is inevitable to consider and estimate this uncertainty. Although there are different approaches...

Improving the Predictive Skill of a Distributed Hydrological Model by Calibration on Spatial Patterns With Multiple Satellite Data Sets

Dembele, M. (author), Hrachowitz, M. (author), Savenije, Hubert (author), Mariéthoz, Grégoire (author), Schaefli, Bettina (author)

Hydrological model calibration combining Earth observations and in situ measurements is a promising solution to overcome the limitations of the traditional streamflow-only calibration. However, combining multiple data sources in model calibration requires a meaningful integration of the data sets, which should harness their most reliable...

Comparing floodplain evolution in channelized and unchannelized urban watersheds in Houston, Texas

Juan, Andrew (author), Gori, Avantika (author), Sebastian, Antonia (author)

In this study, we compare the ability of two riverine flood control approaches: channelization and stream preservation/setbacks, to alleviate the adverse impacts of rapid urbanization. To study the effects of structural intervention and urban development on the evolution of the floodplain, we have chosen two neighboring urban watersheds in...

Physically-based landslide prediction over a large region: Scaling low-resolution hydrological model results for high-resolution slope stability assessment

Wang, S. (author), Zhang, Ke (author), van Beek, Ludovicus P.H. (author), Tian, X. (author), Bogaard, T.A. (author)

Rainfall-triggered shallow landslides are widespread natural hazards around the world, causing many damages to human lives and property. In this study, we focused on predicting landslides in a large region by coupling a 1 km-resolution hydrological model and a 90 m-resolution slope stability model, where a downscaling method for soil moisture...

Practical experience of sensitivity analysis: Comparing six methods, on three hydrological models, with three performance criteria

Wang, Anqi (author), Solomatine, D.P. (author)

Currently, practically no modeling study is expected to be carried out without some form of Sensitivity Analysis (SA). At the same time, there is a large number of various methods and it is not always easy for practitioners to choose one. The aim of this paper is to briefly review main classes of SA methods, and to present the results of the...

Okello, Aline M.L.Saraiva (author), Masih, Ilyas (author), Uhlenbrook, S. (author), Jewitt, Graham P.W. (author), van der Zaag, P. (author)

The variability of rainfall and climate, combined with land use and land cover changes, and variation in geology and soils makes it a difficult task to accurately describe the key hydrological processes in a catchment. With the aim to better understand the key hydrological processes and runoff generation mechanisms in the semi-arid meso-scale...

Multiobjective analysis of green-blue water uses in a highly utilized basin: Case study of Pangani Basin, Africa

Kiptala, J.K. (author), Mul, Marloes L. (author), Mohamed, Yasir A. (author), van der Zaag, P. (author)

The concept of integrated water resource management (IWRM) attempts to integrate all elements of water resources. Different tools are developed to assist in developing sound IWRM plans. One such tool is multiobjective analysis using an integrated hydro-economic model (IHEM). However, IHEM mainly deals with the optimization of river flow (blue...

Discussion of “Perceptual models of uncertainty for socio-hydrological systems: a flood risk change example” ^*

Ertsen, M.W. (author)

Dealing with uncertainty is key in socio-hydrological analysis. As such, thinking through what uncertainties mean for whom and when is key. This discussion contribution introduces three issues related to defining uncertainties. The first issue deals with the problem of defining uncertainty as a given external reality. The second issue deals with...

Constraining Conceptual Hydrological Models With Multiple Information Sources

Nijzink, R.C. (author), Almeida, S. (author), Pechlivanidis, I. G. (author), Capell, R. (author), Gustafssons, D. (author), Arheimer, B. (author), Parajka, J. (author), Freer, J. (author), Han, D. (author), Wagener, T. (author), van Nooijen, R.R.P. (author), Savenije, Hubert (author), Hrachowitz, M. (author)

The calibration of hydrological models without streamflow observations is problematic, and the simultaneous, combined use of remotely sensed products for this purpose has not been exhaustively tested thus far. Our hypothesis is that the combined use of products can (1) reduce the parameter search space and (2) improve the representation of...

The Value of Using Multiple Hydrometeorological Variables to Predict Temporal Debris Flow Susceptibility in an Alpine Environment

Prenner, D.K. (author), Kaitna, R. (author), Mostbauer, K. (author), Hrachowitz, M. (author)

Debris flows are typically triggered by rainfall-related weather conditions—including short-duration storms and long-lasting rainfall, in cold climates sometimes in connection with intensive snowmelt. Given the considerable observational uncertainties of rainfall, we tested if other hydrometeorological variables carry enough information...
