Water Resources Data
We provide high value water data suitable for impact studies of climate change on water resources and extremes, including floods and droughts, for water management planning and water uses.
What is a prospective study of water resources ?
A long-term water study on the evolution of the water resource (surface and groundwater) and the water uses in a river basin in any country requires making future projections of the key variables of the water balance (evapotranspiration, groundwater, runoff, snow cover) and streamflow. This involves using hydrological models forced by climate projections to get an accurate estimate of what to expect in the future, such as the impact of climate change on water resources. Such hydrological model can support decision makers in developing sustainable water use policies for generations to come.
If the climate-hydrological modeling chain is a prerequisite step in impact studies of climate change on water resources, climate change is not the only factor affecting water resources. Human impact is an essential determinant of hydrological behaviors in most catchments. Thus, it is necessary to set up hydrological models that integrate land use, including anthropogenic activities.
Why request data on water resources ?
Also, in a view to support decision in water resources management or water sharing between users, a comprehensive insight on water and their future trends are essential.
Our in-house expertise in hydrology, remote sensing, and numerical modeling have led us to produce regionalized hydrological projections of water stock and availability at the scale of hydrological units within a hydrosystem.
What is a hydrological risk ?
Hydrological risks are caused by extreme weather events. Floods and droughts are the two major water-related risks. But, before the risk comes the hazard. The two hydro-hazards that need to be considered are the high and low flows. Human influence can reduce or enhance hydro-hazards.
Fluvial, or riverine flooding, occurs when excessive precipitation over a long period of time causes a river to exceed its capacity. In the case of groundwater flooding, the risk is suffered. But human activities through land use changes and urbanization lead to increases in a range of consequential flood risks such as urban flood risk.
Drought is caused by persistent and unusual precipitation deficit (meteorological drought) affecting the hydrological balance with reduced streamflow in river (hydrological drought) and leading to a soil moisture deficit that limits water availability for natural vegetation and crops (agricultural drought).
For who ?
The water data we provide are intended for local authorities as well as financers and insurance, infrastructures sector, farmers, or water management.
