satellite HUB through private access configured. It is conditioned to be within range of the
network operator on the installation point.
Radio communication between Stations: These stations are close together and each of them
has a device, one being the main device, that link all the stations and the main device is
responsible for transmitting the whole data pack to the CECU using the system Vsat
Communications between CECU located in Ourense and satellite hub located in Madrid are linked
through two connections, running one as backup in case of fall of the other link. In Miño-Sil SAIH
the main link is done via optical fiber and the secondary through satellite communication as a
normal SAIH station.
1. WFD MONITORING SYSTEMS IN MIÑO-SIL RIVER BASIN AUTHORITY. PROTECTED AREAS (WFD)
DVB-RCS network of Miño-Sil SAIH provides four integrated services within the same system:
 Data transmission service
The stations send data collected by the sensors, every 5 minutes, to the operator HUB. From here
are sent to CECU (main terrestrial channel or double jump satellite subchannel).
 Remote Service
Two-way communication between SAIH Basin Center and control stations. Remote control and
remote management of tasks.
 Phone Service
Supports IP voice communications through the switched network, which is capable of multiple
bond between all points (control stations and basin center), so that either of them can connect to
the rest. The available bandwidth enables the establishment of two simultaneous voice sessions
between SAIH Basin Center and any of the monitoring stations.

MODELING AND DECISION SUPPORT SYSTEM (SAD)
The hydrologic modeling system implemented in the Miño-Sil watershed, comprises a series of hydrologic,
hydraulic and meteorological models. The models that are developed and run periodically are:

METEOROLOGICAL MODELS

RAINMUSIC. Hydro-meteorological model which uses a Bayesian technique to merge rain gauge and
meteorological radar data to produce a distributed estimation (both in spatial and quantitative terms) of
rainfall fields with a lower uncertainty.

Model inputs: Rain rate measured at the SAIH’s weather stations and radar data supplied by AEMet
through an ftp server.

Model outputs: The model generates new spatially distributed imagery of rainfall fields throughout the
Miño-Sil watershed, with a spatial and temporal resolution of 2kmx2km and one hour, respectively.
2. WFD MONITORING SYSTEMS IN MIÑO-SIL RIVER BASIN AUTHORITY. AUTOMICAL MONITORING
SYSTEM.
MODELING AND DECISION SUPPORT SYSTEM (SAD)

HYDROLOGIC MODELS


ASTER: snowmelt runoff model which enables the quantification of water volumes, stored as snowpack in the
Spanish high mountain environments, and water flow evolution yield by snow melting processes.

Model inputs: Initial conditions are set on the basis of rainfall and temperature areal data (from SAIH’s
records); rainfall and temperature forecasts (HIRLAM) are used for stream flow prediction along the
following 72 hours.

Model outputs: Simulated and predicted stream flow at the monitored points; snow water volumes at
the monitored points; and a grid of simulated and predicted snow accumulation.
TOPKAPI: distributed, physically based, hydrologic model which performs an input rainfall balance on a cell by
cell basis, propagates the result according to physical flow equations and estimates both surface and
subsurface runoff. Physical soil parameters (soil depth, saturated hydraulic conductivity, saturated residual
content, and saturated water content), runoff parameters (surface roughness), and channel parameters
(channel roughness) have been calibrated for the Miño-Sil River basin.

Model inputs: Rainfall, temperature and flow rate recorded by SAIH’s stations are the basis to set the
initial soil moisture conditions. Stream flow prediction uses the weather forecast supplied by AEMet
(HIRLAM) for the next 72 hours.

Model outputs: Simulated stream flow for the initial conditions fitting stage, and forecast stream flow
at the SAIH’s flow gage locations for the next 72 hours.
2. WFD MONITORING SYSTEMS IN MIÑO-SIL RIVER BASIN AUTHORITY. AUTOMICAL MONITORING
SYSTEM.
MODELING AND DECISION SUPPORT SYSTEM (SAD)

RESERVOIR MANAGEMENT MODEL (MGE): reservoir management model for flood simulation, based on four
probable cases of reservoir maneuver:
Case 1: Using the Volumetric Evaluation method (Girón).
Case 2: Assuming the closure of every spill element during the whole flood or analysis period.
Case 3: Assuming the initial position of flood control elements during the flood period.
Case 4: Assuming the full opening of flood control elements during the whole flood or simulation period.
 Model inputs: Stream flow predicted by TOPKAPI model constitute the inlet hydrograph of the reservoir.
 Model outputs: Reservoir discharge according to the four defined management cases.

MODELING AND DECISION SUPPORT SYSTEM (FEWS)

HYDRAULIC MODELS



HEC-RAS: hydraulic model freeware developed by HEC-USACE (Hydrologic Engineering Center of the United
States Army Corps of Engineers) which is able to perform one-dimensional, open channel , hydraulic
calculations.

Model inputs: Stream flow predicted by TOPKAPI model at the monitored sites in Lugo.

Model outputs: Water stages associated with maximum flow rates yield by TOPKAPI at the monitored
sites in the town of Lugo.
SOBEK: hydraulic model aimed to simulate the hydrodynamic behavior of floods in open areas. This software
enables the simulation of the flood hydrographs and predicts the water stages reached along a channel (1D
model).

Model inputs: Stream flow predicted by TOPKAPI model at the monitored sites in Lugo.

Model outputs: Maximum water stages associated with the flow hydrographs yield by TOPKAPI at the
monitored sites in the town of Lugo.
IBER: bi-dimensional hydraulic model which is able to simulate flood flows in rivers and estuaries, promoted
by Centro de Estudios Hidrográficos of CEDEX. The model comprises a hydrodynamic module which solves the
bi-dimensional St. Venant equations (also known as Shallow Water Equations-SWE).

Model inputs: Stream flow predicted by TOPKAPI model at the monitored sites in Sarria.

Model outputs: Maximum water stages associated with the flow hydrographs yield by TOPKAPI at the
monitored sites in the village of Sarria.
