TL;DR: In this article, a conceptual reach-based model of interactions between bed sediment and river water has been used to estimate relative differences in bed-sediment SRP flux transfers, demonstrating the role of bed sediments in riverine ‘selfcleansing’ mechanisms.

TL;DR: In this article, the spatial variation of rain in a 80 km2 mountain area (2100-2800 m a.s.) in the Northern Tigray region, and how this variation is influenced by topography, geographical position and lithology, were analyzed.

TL;DR: In this article, three complementary relationship models using the complementary relationship approach for estimating areal actual evapotranspiration were evaluated and compared in three study regions representing a large geographic and climatic diversity: NOPEX region in Central Sweden (cool temperate, humid), Baixi catchment in Eastern China (subtropical, humid) and the Potamos tou Pyrgou River catchment of Northwestern Cyprus (semiarid to arid).

TL;DR: The Danish National Aquatic Monitoring and Assessment Programme (NOVA) was launched in 1988 following the adoption of the first Danish Action Plan on the Aquatic Environment in 1987 with the aim to reduce by 50% the nitrogen (N) loading and by 80% the phosphorus (P) loading to the aquatic environment as discussed by the authors.

TL;DR: In this article, the effects of impervious area, septic leach-field effluent, and a riparian wetland on runoff generation were studied in three small headwater catchments that represent a range of suburban development (high density residential, medium density residential and undeveloped) within the Croton River basin, 70 km north of New York City.

TL;DR: This paper explores Bayesian Markov Chain Monte Carlo methods for evaluation of the posterior distributions of flood quantiles, flood risk, and parameters of both the log-normal and Log-Pearson Type 3 distributions.
