Накратко на български

Динамиката на наносите в делтите и крайбрежията се изследва чрез нови методи за измерване на концентрацията на частици във водата. Това помага за по-точното управление на пристанищата и плажовете, като намалява разходите за тяхното почистване и поддръжка.

Breaking frontiers in long-term, high-frequency monitoring of sediment dynamics across Europe

A proper understanding of sediment transport is extremely important in many areas of engineering and socio-economic development. On time scales of months to years, the knowledge of where sediment accumulates could save billions of dollars on annual port dredging and beach nourishment. On length scales of deltas, estuaries and coastal zones, such knowledge plays a crucial role for decision-makers to govern the development of a country or region. Current practices are based on combining one or more optical and acoustic sensors with gravimetric measurements of filtered water samples to derive a regression model to infer the suspended particulate matter concentrations (SPMC). Owing to the strong dependence on particle size, density and shape, all sensors and the regression model must be recalibrated as soon as the SPM composition changes. This is especially pertinent in transitional regions of fluvial to coastal systems or in more energetic conditions, e.g., storm or high tide, when both mud and sand are expected in the suspension. Therefore, the overall objective of this project is to develop a practical, state-of-the-art methodology and guideline which helps to 1) reduce the tedious process of calibrations, 2) increase the accuracy of in situ measurements and 3) apply this novel methodology to field measurement across Europe.

Цел на проекта

A proper understanding of sediment transport is extremely important in many areas of engineering and socio-economic development. On time scales of months to years, the knowledge of where sediment accumulates could save billions of dollars on annual port dredging and beach nourishment. On length scales of deltas, estuaries and coastal zones, such knowledge plays a crucial role for decision-makers to govern the development of a country or region. Unfortunately, high-fidelity, long-term in situ data of sediment transport, particularly suspended particulate matter concentration are often unavailable and/or unreliable. Hence, this project aims to propose a novel approach to reduce the calibration effort and improve the accuracy of long-term, high-frequency in situ measurements. This project will integrate field and laboratory studies to demonstrate that combination of at least one pair of optical and acoustic (O/A) sensors will help to see the mud better and hear the sand better, which in turn allows us to comprehensively reproduce detailed information of suspended sediment concentration profile in a river, estuarine or coastal zone. Field measurements help to provide input of the boundary conditions for the experiments, whereas the experiments help to isolate variables in order to decipher the behavior of O/A signals that occur in nature. This project will 1) enhance understanding of O/A signals behaviors under similar and different environments, 2) derive empirical functions from field and lab data to describe the ratio of O/A signals as a dependent variable of environmental characteristics and 3) test the functionality and efficiency of the empirical functions, obtained above, with field data collected from different parts of Europe. The primary intellectual merit of this project will be a guideline for water agencies and local authorities throughout Europe and the world to improve their performance in long-term, high-frequency monitoring of water quality.
