Presentation from MOROCCO Mr
Hydrology is led in a structure made of
2 main directions : one for the building of dams and one for research and
planification of water. There is also a temporary direction for the dam
of Alwahda, a legislative division of waters, a division of the administrative
affairs and training, a division of programmes and finances, 7 divisions
for the regional direction of public works, 41 divisions for the provincial
direction of public works.
Structure de la Direction Générale
The direction for research and water planification
is made of :
1. a division of water resources
2. a division of water planification
3. a division for water quality
4. a division for supply in drinkable water
of rural zones.
5. 9 regional directions.
General presentation of hydrologic
The network works mainly with a radio network.
They manage primary stations (they are
distributed per basin).These primary stations transmit the data to the
regional division which transmit them to the general direction where the
data are loaded in a big computer system.
They manage 241 main stations, among which
141 are equipped with transmitter/receiver.

The objectives of the flood forecasting
network are :
The means :
the protection of the floodable zones. These
are very sensitive not only for protection of the soils but also for inhabitants,
the management of the hydraulic works,
the management of the hydrometrical network.
The network is made of primary stations
(one station on the dam and one climatological station) and of direction
The headquarters are located in Rabat.
The flood forecasting network has 141
The equipment must be maintained in good
conditions of functioning.
The equipment of the primary stations
is automatic recorders on charts, secondary stations are equipped with
Operation of the network
The network works as follows :
The observations that are done at the primary
and main stations are rainfall at rain gauges, reading at staff gauges,
the classical climatological data and specific observations are made at
Routine regime (4 records a day at 8, 11,
15 and 18 h., they measure rainfall, water level and atmospheric pressure);
Prealert regime that runs as soon a rainfall
Alert regime that runs as soon as a flood
Serious regime that runs when the dams are
There is a hierarchy to respect in the
transmission of data. An observer lives near the station and transmits
the data. The decision of the passage from the routine regime to the prealert
one or from the prealert to the alert regime or from alert to serious regime
is taken by Rabat.
Maintenance of the equipment
The automatic water level recorders, the
rain gauges and the radio transmission equipment are regularly maintained.
