Spatial optimization of nutrient reduction measures on agricultural land to improve water quality: A coupled modeling approach

Canadian Journal of Agricultural Economics/Revue canadienne d'agroeconomie, Volume 71, Issue 3-4, Page 329-353, September-November 2023., 2023
Abstract The objective of this study is to identify the optimal spatial distribution of Best Management Practices (BMPs) to reduce total phosphorus (TP) runoff from agricultural land in the largest Canadian watershed draining into Lake Erie, the Great Lake most vulnerable to eutrophication.

The “Environment Making State” and Climate Change: The French “Cat Nat” Reinsurance Scheme Under Strain

Antipode, Volume 55, Issue 2, Page 506-526, March 2023., 2023
Abstract In 2012, SCOR, one of the world's largest reinsurers, sued the French state, challenging a public–private natural disaster insurance scheme, called the “cat nat” regime. It campaigned in favour of a “real” natural disaster insurance market. The purpose of this paper is to grasp the logic of this litigation.

Forest regeneration can positively contribute to local hydrological ecosystem services: Implications for forest landscape restoration

Journal of Applied Ecology, Volume 58, Issue 4, Page 755-765, April 2021., 2021
Encouraging natural regeneration is increasingly seen as a cost‐effective way to deliver forest landscape restoration. Our data suggest that increasing the abundance of young secondary forest in the tropics, by increasing fallow lengths in the shifting cultivation cycle, could make a positive contribution to locally important hydrological ecosystem ...

Laboratory Development of a Passive Proportional Sampler for Overland FlowStudies in Agricultural Fields [PDF]

, 2015
peer-reviewedWater-quality in many rivers remains poor and needs to be improved. Diffuse pollution continues to cause difficulties. Some instruments are available which can monitor pollution of rivers from land.

Précisions au sujet des termes de débit, d’écoulement et de ruissellement en hydrologie [PDF]

, 1957
Hydrology, one of the most neglected branches of geography, is primarily the study of flowing waters derived from precipitations. Hence, the words « discharge » , «  flow » and « run-off » are at the core of research in this field.

Étude des pertes au ruissellement sur surfaces imperméables en milieu urbain. [PDF]

, 1997
L'étude de la réponse hydrologique de deux bassins versants de l'agglomération de Bordeaux en France a montré que les pertes initiales au ruissellement sur les surfaces imperméables étaient responsables des écarts entre le volume ruisselé et le volume ...

The effects of improved subsurface drainage on runoff and nitrogen leaching from a clayey field section

Irrigation and Drainage, Volume 73, Issue 4, Page 1408-1423, October 2024.
Abstract The aim of this study was to investigate the effects of improved subsurface drainage installation on nitrogen (N) loss in drain discharge (DD) and topsoil layer runoff (TLR). Data on DD and TLR, as well as on concentrations of total, nitrate and ammonium N in the runoff components, were collected from four sections of an experimental field in ...

Combined use of physically based hydrological model and empirical models to improve parameterisation of erosion processes in a flash flood prone catchment

Earth Surface Processes and Landforms, Volume 49, Issue 12, Page 3934-3948, 30 September 2024.
Estimation of erosion during flash floods using the physics‐based model MARINE is compared with two empirical models RUSLE and MUSLE. Simulations with MARINE show that events can be classified into those dominated by raindrop erosion and those dominated by shear stress erosion. The eroded volumes simulated by the three models are comparable, except for
