Towards systematic planning of small-scale hydrological intervention-based research (discussion paper)

Pramana, K.E.R. (author), Ertsen, M.W. (author), Van de Giesen, N.C. (author)

Many small-scale water development initiatives are accompanied by hydrological research to study either the shape of the intervention or its impacts. Humans influence both, and thus one needs to take human agency into account. This paper focuses on the effects of human actions in the intervention and its associated hydrological research, as...

Improved GRACE regional mass balance estimates of the Greenland Ice Sheet cross-validated with the input-output method (discussion paper)

Xu, Z. (author), Schrama, E.J.O. (author), Van der Wal, W. (author), Van den Broeke, M. (author), Enderlin, E.M. (author)

In this study, we use satellite gravimetry data from the Gravity Recovery and Climate Experiment (GRACE) to estimate regional mass changes of the Greenland ice sheet (GrIS) and neighbouring glaciated regions using a least-squares inversion approach. We also consider results from the input-output method (IOM) that quantifies the difference...

NOx emission estimates during the 2014 Youth Olympic Games in Nanjing

Ding, J. (author), Van der A, R.J. (author), Mijling, B. (author), Levelt, P.F. (author), Hao, N. (author)

The Nanjing Government applied temporary environmental regulations to guarantee good air quality during the Youth Olympic Games (YOG) in 2014. We study the effect of those regulations by applying the emission estimate algorithm DECSO (Daily Emission estimates Constrained by Satellite Observations) to measurements of the Ozone Monitoring...

Impact of aerosols on the OMI tropospheric NO2 retrievals over industrialized regions: How accurate is the aerosol correction of cloud-free scenes via a simple cloud model? (discussion paper)

Chimot, J.J. (author), Vlemmix, T. (author), Veefkind, J.P. (author), De Haan, J.F. (author), Levelt, P.F. (author)

The Ozone Monitoring Instrument (OMI) instrument has provided daily global measurements of tropospheric NO2 for more than a decade. Numerous studies have drawn attention to the complexities related to measurements of tropospheric NO2 in the presence of aerosols. Fine particles affect the OMI spectral measurements and the length of the average...

Estimation of predictive hydrologic uncertainty using the quantile regression and UNEEC methods and their comparison on contrasting catchments

Dogulu, N. (author), Lopez Lopez, P. (author), Solomatine, D.P. (author), Weerts, A.H. (author), Shrestha, D.L. (author)

In operational hydrology, estimation of the predictive uncertainty of hydrological models used for flood modelling is essential for risk-based decision making for flood warning and emergency management. In the literature, there exists a variety of methods analysing and predicting uncertainty. However, studies devoted to comparing the performance...

How large-scale subsidence affects stratocumulus transitions (discussion paper)

Van der Dussen, J.J. (author), De Roode, S.R. (author), Siebesma, A.P. (author)

Some climate modeling results suggest that the Hadley circulation might weaken in a future climate, causing a subsequent reduction in the large-scale subsidence velocity in the subtropics. In this study we analyze the cloud liquid water path (LWP) budget from large-eddy simulation (LES) results of three idealized stratocumulus transition cases...

Revised predictive equations for salt intrusion modelling in estuaries

Gisen, J.I.A. (author), Savenije, H.H.G. (author), Nijzink, R.C. (author)

For one-dimensional salt intrusion models to be predictive, we need predictive equations to link model parameters to observable hydraulic and geometric variables. The one-dimensional model of Savenije (1993b) made use of predictive equations for the Van der Burgh coefficient $K$ and the dispersion at the seaward boundary D0. Here we have...

The open boundary equation (discussion paper)

Diederen, D. (author), Savenije, H.H.G. (author), Toffolon, M. (author)

We present a new equation describing the hydrodynamics in infinitely long tidal channels (i.e., no reflection) under the influence of oceanic forcing. The proposed equation is a simple relationship between partial derivatives of water level and velocity. It is formally derived for a progressive wave in a frictionless, prismatic, tidal channel...

Quantification of the influence of preferential flow on slope stability using a numerical modelling approach

Shao, W. (author), Bogaard, T.A. (author), Bakker, M. (author), Greco, R. (author)

The effect of preferential flow on the stability of landslides is studied through numerical simulation of two types of rainfall events on a hypothetical hillslope. A model is developed that consists of two parts. The first part is a model for combined saturated/unsaturated subsurface flow and is used to compute the spatial and temporal water...

Hydrological model parameter dimensionality is a weak measure of prediction uncertainty (discussion paper)

Pande, S. (author), Arkesteijn, L. (author), Savenije, H.H.G. (author), Bastidas, L.A. (author)

This paper shows that instability of hydrological system representation in response to different pieces of information and associated prediction uncertainty is a function of model complexity. After demonstrating the connection between unstable model representation and model complexity, complexity is analyzed in a step by step manner. This is...

New estimates of potential impacts of sea level rise and coastal floods in Poland (discussion paper)

Paprotny, D. (author), Terefenko, P. (author)

Polish coastal zone is thought to be of the most exposed to sea level rise in Europe. With climate change expected to raise mean sea levels between 26 and 200 cm by the end of the century, and storms increasing in severity, accurate estimates of those phenomena are needed. Recent advances in quality and availability of spatial data in Poland...
