Floods are recurrent phenomena with significant environmental and socio-economic impacts. The risk of flooding increases when land use changes. objective this research is to detect cover changes via Sentinel-2 images in the Umia Basin (Galicia, NW Spain) 2016–2021 analyse associated flood risk. This study focuses on how forest nature-based solutions (NBS) can reduce hazard cities crops high-ris...

Catchment models are by definition simplified representations of the real world system. This aggregation takes place in space and time and has several important consequences. First, there are no generally applicable rules to perform this aggregation, and the resulting model structure is usually a function of the modeller’s hydrological understanding. Secondly, the model parameters cannot be mea...

THE EPIDEMIOLOGIC CATCHMENT AREA (ECA) Program is a developmental series of epidemiologic research studies performed by independent research teams in collaboration with the Center for Epidemiologic Studies (CES) of the Division of Biometry and Epidemiology, National Institute of Mental Health (NIMH). The broad aims of the Program are the historical goals of psychiatric epidemiology, to estimate...

the chemical speciation of heavy metals (arsenic, chromium, copper, lead, zinc and tin) in the sediments offormer tin mining catchment bestari jaya, peninsular malaysia was determined by using the latest version of the community bureau of reference, usually called the bcr 3-step sequential extraction procedure. furthermore, a fourth step was introduced for digestion and analysis of the residue....

Tukad Kelandis is a tributary of the Ayung Watershed which located downstream. In 2021 floods occurred in resulting one places affected by flooding, namely Art Center area. So it necessary to do research on analysis peak flood discharge river using rational methods. Maximum runoff occurs when rainfall during same time as catchment area concentration method. Based results, amount planned watersh...

Increasing iron (Fe) concentrations are found in lakes on a wide geographical scale but exact causes still debated. The observed trends might result from increased Fe loading the terrestrial catchment, also changes how distributes between water column and sediments. To get better understanding of we investigated whether there has been any change sediment formation sulfides (FeS) as an sink resp...

Hydrological modeling for landscape and catchment scale applications requires upscaling of soil hydraulic parameters which are generally only available at point scale. We present a case study where hourly root zone water content drainage observations from nine flat, pastoral sites (Waikato Canterbury regions in New Zealand) were used to develop an approach parameterize the balance module TopNet...

The RAIN and CLIMEX experiments at Risdalsheia, southernmost Norway, together cover 17 years (1984-2000) of whole-catchment manipulation of acid deposition and climate. A 1200 m2 roof placed over the forest canopy at KIM catchment excluded about 80% of ambient acid deposition; clean rain was sprinkled under the roof. A climate change treatment (3.7oC increase in air temperature and increase in ...

The purpose of the study was to determine the role of land use, seasonality, and hydrometeorological conditions on the relationship between stream water potassium (K+) concentration and discharge during different types of floods-short- and long-duration rainfall floods as well as snowmelt floods on frozen and thawed soils. The research was conducted in small catchments (agricultural, woodland, ...
