Urban River Water Level Increase Through Plastic Waste Accumulation at a Rack Structure

Plastic debris in water systems is a major challenge for our ecosystem, because it is extremely persistent in the environment. Apart from the importance of reducing the amount of plastic entering the ocean, clearing the rivers from debris is important for societal concerns, such as flood risks. Plastic waste accumulation at trash racks leads...

The impacts of heating strategy on soil moisture estimation using actively heated fiber optics

Several recent studies have highlighted the potential of Actively Heated Fiber Optics (AHFO) for high resolution soil moisture mapping. In AHFO, the soil moisture can be calculated from the cumulative temperature (T_cum), the maximum temperature (T_max), or the soil thermal conductivity determined from the cooling phase...

Systematic high-resolution assessment of global hydropower potential

Population growth, increasing energy demand and the depletion of fossil fuel reserves necessitate a search for sustainable alternatives for electricity generation. Hydropower could replace a large part of the contribution of gas and oil to the present energy mix. However, previous high-resolution estimates of hydropower potential have been local...

Online estimation of flood damage in The Netherlands

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...

Double-ended calibration of fiber-optic Raman spectra distributed temperature sensing data

Over the past five years, Distributed Temperature Sensing (DTS) along fiber optic cables using Raman backscattering has become an important tool in the environmental sciences. Many environmental applications of DTS demand very accurate temperature measurements, with typical RMSE < 0.1 K. The aim of this paper is to describe and clarify the...
