Urbanization vs climate drivers: investigating changes in fluvial floods in Poland

Nelson Venegas Cordero, Luis Mediero, Mikolaj Piniewski

Published: 2024-04-11
Subjects: Hydrology

Fluvial floods are one of the most severe natural hazards. Changes in flood behaviour result from an interplay of climatic and human factors. Urbanization, with increasing land imperviousness, is the most critical human factor. This study investigates the effect of urbanization vs climate drivers on river floods in Poland, using the paired catchment approach. We used daily river flow data from [...]

Southwestern North America is currently experiencing a multidecadal megadrought, with severe consequences for water resources. However, significant uncertainty remains about how precipitation will change in the 21st century in this semi-arid region. Paleoclimatic records are essential for both contextualizing current change, and for helping constrain the sensitivity of regional hydroclimate to [...]

EStreams: An Integrated Dataset and Catalogue of Streamflow, Hydro-Climatic Variables and Landscape Descriptors for Europe

Subjects: Earth Sciences, Environmental Sciences, Hydrology

Global hydrology datasets have become increasingly available, contributing to important scientific advances. However, in Europe, only a few such datasets were published and they only capture a fraction of the wealth of information national data providers have. We present “EStreams”, an extensive catalogue of openly available stream records and a dataset of hydro-climatic variables and landscape [...]

Subjects: Earth Sciences, Environmental Monitoring, Environmental Sciences, Hydrology, Sustainability, Water Resource Management

Irrigated agriculture is the dominant use of water globally, but most water withdrawals are not monitored or reported. As a result, it is largely unknown when, where, and how much water is used for irrigation. Here, we evaluated the ability of remotely sensed evapotranspiration (ET) data, integrated with other datasets, to calculate irrigation water withdrawals and applications in an [...]

The objective of this paper is to present the initial illustration of a cyberinfrastructure named the River MORPhology Information System (RIMORPHIS) that addresses the current limitations related to river morphology data and tools. A new specification for data and semantics on river morphology datasets has been developed to support the web-based platform for discovering and visualization of [...]

River Floodplains, Organic Carbon, and Paleoclimate: How River Dynamics Impart Biases in the Biogeochemical Climate Record of Terrestrial Landscapes

Anjali M Fernandes, Michael T Hren, Virginia B. Smith, et al.

Subjects: Earth Sciences, Geochemistry, Geomorphology, Hydrology, Physical Sciences and Mathematics, Sedimentology, Stratigraphy

River floodplains can be both sources and sinks for organic carbon. In the sedimentary record, geochemical signatures of terrestrial water availability record climate and ecology along river corridors in deep time. However, paleoenvironmental reconstructions are often confounded by the complex dynamics of organic carbon residence, entrainment, and deposition in a fluvial system. As alluvial [...]

Wealth over Woe: global biases in hydro-hazard research

Lina Stein, S. Karthik Mukkavilli, Birgit M. Pfitzmann, et al.

Subjects: Computer Sciences, Hydrology, Nature and Society Relations, Sustainability

Floods, droughts, and rainfall-induced landslides are hydro-geomorphic hazards that affect millions of people every year. Anticipation, mitigation, and adaptation to these hazards is increasingly outpaced by their changing magnitude and frequency due to climate change. A key question for society is whether the research we pursue has the potential to address knowledge gaps and to reduce potential [...]

Open-source approach for reproducible substrate mapping using semantic segmentation on recreation-grade side scan sonar datasets

Knowledge of the variation and distribution of substrates at large spatial extents in aquatic systems, particularly rivers, is severely lacking, impeding species conservation and ecosystem restoration efforts. Air and space-borne remote sensing important for terrestrial and atmospheric measurements are limited in benthic environments due to river stage, turbidity, and canopy cover, requiring [...]

PHOTOMOB: AUTOMATED GIS METHOD FOR ESTIMATION OF FRACTIONAL GRAIN DYNAMICS IN GRAVEL BED RIVERS. PART 1: GRAIN SIZE

Particle entrainment intensity is spatially and temporally variable, making it a complex phenomenon to measure. This paper is the first of a pair, in which we present an automated image processing procedure (PhotoMOB) for monitoring the mobility/stability of gravel river beds. The method is based on local comparison of the shape of the grains identified at the same coordinates between successive [...]

Machine learning (ML) has an increasing role in the hydrological sciences, and in particular, certain types of time series modeling strategies are popular for rainfall-runoff modeling. A large majority of studies that use this type of model do not follow best practices, and there is one mistake in particular that is very common: training deep learning models on small, homogeneous data sets (i.e., [...]
