TLDR
In this article, the authors quantified the nadir altimetry performance over a medium river (200m or lower wide) with a pluvio-nival regime in a temperate climate (the Garonne River, France).About:

The Lake Chad hydrology under current climate change
Binh Pham-Duc,Binh Pham-Duc,Florence Sylvestre,Fabrice Papa,Fabrice Papa,Frédéric Frappart,Camille Bouchez,Jean-François Crétaux +7 more
TL;DR: It is shown that Lake Chad extent has remained stable during the last two decades, despite a slight decrease of its northern pool, and groundwater, which contributes to ~70% of Lake Chad’s annual water storage change, is increasing due to water supply provided by its two main tributaries.

An improved approach to monitoring Brahmaputra River water levels using retracked altimetry data
TL;DR: In this paper, an improved approach for deriving water levels in high-mountain regions with complex terrain is proposed, comprising an improved footprint selection and an improved waveform retracking, called the 50% threshold and ice-1 combined algorithm (TIC), which was applied to river channels of varying widths, ranging from 200 m in the UBR to more than 1 km in the LBR.

Monitoring Water Levels and Discharges Using Radar Altimetry in an Ungauged River Basin: The Case of the Ogooué
Sakaros Bogning,Frédéric Frappart,Fabien Blarel,Fernando Niño,Gil Mahé,Jean-Pierre Bricquet,Frédérique Seyler,Raphael Onguene,Jacques Etame,Marie-Claire Paiz,Jean-Jacques Braun +10 more
TL;DR: The combination of data from all the radar altimetry missions near Lamabrene resulted in a long-term and significantly improved water-level time series and the concept of VS is extended to the case of drifting orbits using the data from Cryosat-2 in several close locations.

Influence of recent climatic events on the surface water storage of the Tonle Sap Lake
Frédéric Frappart,Sylvain Biancamaria,Cassandra Normandin,Fabien Blarel,Luc Bourrel,M. Aumont,P. Azemar,Phuong Lan Vu,T. Le Toan,Bertrand Lubac,José Darrozes +10 more
TL;DR: This study provides an impact analysis of recent climatic events from El Niño 1997/1998 to El Niño 2015/2016 on surface storage variations in the Tonle Sap watershed determined by combining remotely sensed observations, multispectral images and radar altimetry from 1993 to 2017.

Evolution of the Performances of Radar Altimetry Missions from ERS-2 to Sentinel-3A over the Inner Niger Delta
Cassandra Normandin,Frédéric Frappart,Adama Telly Diepkilé,Vincent Marieu,Eric Mougin,Fabien Blarel,Bertrand Lubac,Nadine Braquet,Abdramane Ba +8 more
TL;DR: Cross-correlation analysis performed between water levels from the same altimetry mission leads to time-lags between the upstream and the downstream part of the Inner Niger Delta of around two months that can be related to the time residence of water in the drainage area.

River flow forecasting through conceptual models part I — A discussion of principles☆
J.E. Nash,J.V. Sutcliffe +1 more
TL;DR: In this article, the principles governing the application of the conceptual model technique to river flow forecasting are discussed and the necessity for a systematic approach to the development and testing of the model is explained and some preliminary ideas suggested.

Model Evaluation Guidelines for Systematic Quantification of Accuracy in Watershed Simulations
Daniel N. Moriasi,Jeffrey G. Arnold,M. W. Van Liew,Ronald L. Bingner,R. D. Harmel,Tamie L. Veith +5 more
TL;DR: In this paper, the authors present guidelines for watershed model evaluation based on the review results and project-specific considerations, including single-event simulation, quality and quantity of measured data, model calibration procedure, evaluation time step, and project scope and magnitude.

A global inventory of lakes based on high‐resolution satellite imagery
Charles Verpoorter,Charles Verpoorter,Tiit Kutser,Tiit Kutser,David A. Seekell,David A. Seekell,Lars J. Tranvik +6 more
TL;DR: The abundance and size distribution of lakes is critical to quantifying limnetic contributions to the global carbon cycle as discussed by the authors, however, estimates of global lake abundance are not accurate and are unreliable.
