Variability of low monthly rainfall in La Plata Basin

The spatial variability of runoff and precipitation in the Rio de la Plata basin

A few aspects of spatial variability, connected with climate variability, in the Rio de la Plata basin are analysed through changes in the basin runoff considered as indicative of the annual integrated precipitation. Those changes contain better information on climate variability than the sparse records of precipitation and temperature in view of the high spatial and temporal variability of tho...

Recent La Plata basin drought conditions observed by satellite gravimetry

[1] The Gravity Recovery and Climate Experiment (GRACE) provides quantitative measures of terrestrial water storage (TWS) change. GRACE data show a significant decrease in TWS in the lower (southern) La Plata river basin of South America over the period 2002–2009, consistent with recognized drought conditions in the region. GRACE data reveal a detailed picture of temporal and spatial evolution ...

Generation of Daily Synthetic Precipitation Series: Analyses and Application in La Plata River Basin

Precipitation analysis is embedded in a range of important hydrological studies for hydraulic works construction and maintenance. However, flaws and limitations in records are obstacles often encountered by researchers. One feasible solution for overcoming these obstacles is to generate synthetic series. The main objective of this work is to structure and validate a model for generating synthet...

Impacts of Land Use Change on Ecosystems and Society in the Rio de La Plata Basin

Droughts and Floods in the La Plata Basin in Soil Moisture Data and GRACE

The mapping and forecasting of droughts and floods is an important potential field of application of global soil moisture and water storage products from satellites and models. Especially when extremes in near-surface soil moisture propagate into extremes in total water storage, agricultural production and water supply can be severely impacted. This study relates soil moisture from the WaterGAP...
