Approximately 800 m3 per second


Awesome. Since 1970, the concrete deck is lower, the water would have brushed

No need to order the mayor to prohibit play the following Sunday.
Vincent Garralon builder to the left rue René Crabos has a cellar, one understands why


Road Sainte Eulalie. But today is there no houses right?

It only does he not remember an episode of Don Camillo?
The small chapel near the great river


Tartas Road. The two houses still exist


Route de Mont de Marsan. Nowadays, there is a left-storey residence and the right a supermarket. We understand why in supermarkets, displays are called gondolas!

Route Granada. At Granada, lou SAP that nade!

Ancient pottery, currently owned by Mr. Roma Street Papin


Route de Mont de Marsan.

Firefighters have no boat. We cross the water landed on GMC Normandy, 8 years before. In the foreground, the truck of Saint Sever relieved of his pipe and ladder truck and bottom reinforcements came from Mont de Marsan

Note the telephone lines connecting Mont de Marsan in the townships of Saint Sever and Hagetmau

During the centennial flood of Monday, February 4, 1952, I had almost 5 years. This catastrophe was my first public memory. The second summer after the fire was depositing grains Maysonnave Pontix street.

The siren had sounded several times to prevent fire, the residents of Father and ask for help from the population to evacuate the wheat and flour from the mill Papin.
With my parents, we went by car as my dad parked Avenue de la Gare in non-flood.

We went walking to the roundabout father. Crossing the bridge was awesome. I walked into my parents kept me each a hand. The village priest was an island. The river had opened a second reading from Santa Eulalia, he passed under the railway bridge between Man and Farm Road Grenada, then at the current Intermarché, he crossed the road to Mont de Marsan return to her bed Téré after crossing the road to forging Tartas Pédesert.

Such a catastrophe is it possible today?


Answer yes and no yes and even more serious if a dam upstream is broken by an earthquake, such as the blue lake in Bigorre.

NOT a result of rainfall for several reasons.
Firstly because many hillside dams created in the late twentieth century clipped floods unless they are already full.
In 1952, there is the Mill Dam Papin which is the water table downstream from the stone bridge about 2 meters. Even if the bridge rebuilt in 1970 reduced the flow of water, the flood drains much faster downstream of the disappearance of the dam Papin. To facilitate this phenomenon
evacuation of water, it would nevertheless be wise to cut down all the trees that grew in the riverbed.

What would be the height of water in the stone bridge over the flood level if a 1952 year flood type recur?

To answer this question, we must assume that the surface of the water passing the bridge of stone Dax has not changed since its construction in the early nineteenth century. Thus, the scale of flood Dax is reliable because it is constant.
I will consider three major floods:
Saint Sever 1952 with the existence of the dam Papin
1971 and 1981 without the dam Papin.
You could compare the water level in Dax and St Sever in 1952, 1971 and 1981 and extrapolated to approximate with a new type Raw 1952 on Saint-Sever.
1952 Dax Saint-Sever M 6.52 4.60 M 19.2 m difference
1971 Dax Saint-Sever 5.56 M 2.70 M 2.86 M difference
1981 Dax 3.6 M Saint-Sever difference 2.30 m 3.73 M

If a new flood type 1952 (the second largest flood on the scale of Dax) arrived on the river, there would be around 3.25 m in Saint-Sever is about 1.50 meter less than in 1952.
Nevertheless, it is likely that water will flood the stadium at least 50 cm, is near the parking lot of Intermarket, will surround the ring, will carry all the trees located downstream from the stone bridge and threaten the rear of the father's house. Indeed, the gates protecting the river district of Coulaquère are in ruins.
