Mapping energy balance fluxes and root zone soil moisture in the White Volta Basin using optical imagery

Hendrickx, J.M.H. (author), Hong, S. (author), Friesen, J. (author), Compaore, H. (author), Van de Giesen, N.C. (author), Rodgers, C. (author), Vlek, P.L.G. (author)

Accurate information on the distribution of sensible and latent heat fluxes as well as soil moisture is critical for evaluation of background characteristics. Since these fluxes are subject to rapid changes in time and space, it is nearly impossible to determine their spatial and temporal distributions over large areas from ground measurements...

Online estimation of flood damage in The Netherlands

Hoes, O.A.C. (author), Tariq, M.A.U.R. (author), Van de Giesen, N.C. (author)

This paper presents a recently developed model in the Netherlands for the online estimation of damage caused by floods. The model attempts to fill the lack of a consistent framework for the assessment of damage for all water authorities and all floods in the Netherlands. A framework was necessaiy to be able to evaluate the cost and benefit of...

Application of multi attribute decision making methods to resources allocation problems

Mianabadi, H. (author), Van de Giesen, N.C. (author), Mostert, E. (author), Sheikhmohammady, M. (author)

Operation of over shared resources (water, gas, oil, and mineral reserves) has been one the most significant challenges of states. “Fair” and “efficient” national resources reallocation among stakeholders and states is a complex conflict problem that faces this fundamental question: which criteria and mechanisms should be taken into account for...

Model selection for salt water intrusion in delta areas

Xu, M. (author), Van Overloop, P.J. (author), Van de Giesen, N.C. (author)

Due to land subsidence and sea level rise, salt intrusion in delta areas increases. This is a potential thread for agriculture in these areas. To investigate this thread and measures that can counteract on it, numerical models are developed to mimic the behavior of the water system under different strategies and scenarios. This behavior is...

A comparison between leaf dielectric properties of stressed and unstressed tomato plants

Van Emmerik, T.H.M. (author), Steele-Dunne, S.C. (author), Judge, J. (author), Van de Giesen, N.C. (author)

Leaf dielectric properties influence microwave scattering from a vegetation canopy. The dielectric properties of leaves are primarily a function of leaf water content. Understanding the effect of water stress on leaf dielectric properties will give insight in how plant dynamics change as a result of water stress, and how radar can be used for...

Remotely sensed monitoring of small reservoir dynamics: A Bayesian approach

Eilander, D.M. (author), Annor, F.O. (author), Iannini, L. (author), Van de Giesen, N.C. (author)

Multipurpose small reservoirs are important for livelihoods in rural semi-arid regions. To manage and plan these reservoirs and to assess their hydrological impact at a river basin scale, it is important to monitor their water storage dynamics. This paper introduces a Bayesian approach for monitoring small reservoirs with radar satellite images....

Introduction to special section on Uncertainty Assessment in Surface and Subsurface Hydrology: An overview of issues and challenges

Montanari, A. (author), Shoemaker, C.A. (author), Van de Giesen, N.C. (author)

This paper introduces the Water Resources Research special section on Uncertainty Assessment in Surface and Subsurface Hydrology. Over the past years, hydrological literature has seen a large increase in the number of papers dealing with uncertainty. In this article, we present an overview of the different sources of uncertainty and the...

Data compression to define information content of hydrological time series

Weijs, S.V. (author), Van de Giesen, N.C. (author), Parlange, M.B. (author)

When inferring models from hydrological data or calibrating hydrological models, we are interested in the information content of those data to quantify how much can potentially be learned from them. In this work we take a perspective from (algorithmic) information theory, (A)IT, to discuss some underlying issues regarding this question. In the...

Fiber optic distributed temperature sensing for the determination of air temperature

De Jong, S.A.P. (author), Slingerland, J.D. (author), Van de Giesen, N.C. (author)

This paper describes a method to correct for the effect of solar radiation in atmospheric distributed temperature sensing (DTS) applications. By using two cables with different diameters, one can determine what temperature a zero diameter cable would have. Such a virtual cable would not be affected by solar heating and would take on the...

Design of a low-cost microcontroller-based lightning monitoring device

Kamau, G.M. (author), Kang'ethe, S. (author), Kamau, S.I. (author), Van de Giesen, N.C. (author)

Lightning data is not only important for environment and weather monitoring but also for safety purposes. A device that monitors and keeps track of occurrences of lightning strikes has been developed. A communication interface is established between the sensors, data logging circuit and the microcontroller. The digital outputs of the lightning...

The Trans-African Hydro-Meteorological Observatory (TAHMO)

Van de Giesen, N.C. (author), Hut, R.W. (author), Selker, J. (author)

In this opinion article, we present the Trans-African Hydro-Meteorological Observatory (TAHMO). The goal of TAHMO is to develop a dense network of hydro-meteorological measurement stations throughout sub-Saharan Africa. On average, there will be one station per 1000 km2. The stations will be cost-effective through the use of new sensor and...
