As part of the revised EU Bathing Water Directive, there is scope to discount bathing water quality samples which show poor water quality if poor water quality is predicted and the public forewarned. The Cloud to Coast (C2C) project is developing a model to allow prediction of faecal indicator organism (FIO) concentrations in bathing waters. One of the C2C sub-models is investigating FIO loads ...

Improving the predictive capabilities of rainfall-runoff models in ungauged catchments is a challenging task but has important theoretical and practical significance. In this study, we investigated the predictive capabilities of the conceptual Xinanjiang model (XAJ), which is widely used for flood forecasting and simulation in China, in ungauged catchments. We further produced a hybrid rainfall...

Dramatic changes in hydrological factors in the Weihe River basin are analysed. These changes have exacerbated ecological problems and caused severe water shortages for agriculture, industries and the human population in the region, but their drivers are uncertain. The Mann-Kendall test, accumulated departure analysis, sequential clustering and the sliding t-test methods were used to identify t...

In the context of global urbanization, urban flood risk in many cities has become a serious environmental issue, threatening the health of residents and the environment. A number of hydrological studies have linked urban flooding issues closely to the spectrum of spatial patterns of urbanization, but relatively little attention has been given to small-scale catchments within the realm of urban ...

In this paper, the characterization of catchments extracted from multiscale digital elevation models (DEMs) is performed. First, the lifting scheme is employed to generate multiscale DEMs. The catchments extracted from the generated multiscale DEMs are then characterized based on their numbers. A power law relationship is derived between the number of extracted catchments and the kernel size. T...

The implementation of the Water Framework Directive (WFD) aimed to reduce nutrient export from catchments water courses. Forest operations cause diffuse loading, which challenges efficient targeting protection measures. We formed 100 equally probable clear-cut scenarios, investigate how location clear-cuts influenced total nitrogen (TN) and phosphorous (TP) on different scales. was calculated b...

To understand the behavior of torrential processes in the alpine environment, the conditions mainly responsible for the occurrence of these phenomena have to be identified and distinguished as predisposing and triggering factors. In this regard, this study is aimed to understanding which factors lead to the occurrence of a given torrential processes in alpine catchments in the Western Alps, whe...

The objective of this paper is to assess the performance of methods that predict low flows and flood runoff in ungauged catchments. The aim is to learn from the similarities and differences between catchments in different places, and to interpret the differences in performance in terms of the underlying climate-landscape controls. The assessment is performed at two levels. The Level 1 assessmen...

The flux of terrigenous organic carbon through estuaries is an important and changing, yet poorly understood, component the global cycle. Using dissolved (DOC) fluorescence data from 13 British draining catchments with highly variable land uses, we show that use strongly influences fate DOC across ocean transition via its influence on composition lability constituent matter (DOM). In peatland-d...

We evaluated the impacts of natural wetlands and various land uses on stream nitrogen concentration in two grassland-dominated catchments in eastern Hokkaido, Japan. Analyzing land use types in drainage basins, measuring denitrification potential of its soil, and water sampling in all seasons of 2003 were performed. Results showed a highly significant positive correlation between the concentrat...
