1 EARLY WARNING AND PREVENTION IN HYDROLOGIC WATERSHED
National Institute of Water Resources EARLY WARNING AND PREVENTION IN HYDROLOGIC WATERSHED Havana, February 15, 2012

2 I. PARTY CENTRAL WATER ALL ALONG THE MAIN ISLAND TO DETERMINE THE FORMATION OF SMALL WATERSHED AND SHORT RIVERS. 85% of rivers length of 40 km and basin area no larger than 200 km ². Characterized by sudden flood of short duration Of the 652 surface water basins, 117 (18%) are regulated. These are related to more than 100 major underground hydrogeological units. Close and dynamic relationship between surface water - groundwater - coastal marine waters

3 HEAVY RAINS AND HURRICANES
II. VULNERABILITY OF OUR CONDITION ARCHIPELAGO LOCATED IN THE HUMID TROPICS EXPOSED TO IMPACT OF EXTREME WEATHER EVENTS HEAVY RAINS AND HURRICANES DROUGHT

4 FLOOD AREAS OF THE PROVINCES OF CUBA IN%
Pinar del Río Isla de la Juventud Matanzas Villa Clara Las Tunas Granma Sancti Spiritus Camagüey Ciego de Avila Cienfuegos La Habana Ciudad de La Habana Santiago de Cuba Holguín Guantánamo Between 15 and 25% of floodplain + 25% floodplain Less than 15% of floodplain

5 III. OUR DEPENDENCE OF WATER RESOURCES, THE BEHAVIOR OF PRECIPITATION AND NEED TO MEET SUSTAINABLE WAY, THE CLAIMS OF THE ECONOMY, SOCIETY AND THE ENVIRONMENT.

IV. CLIMATE VARIABILITY WHICH IS REFLECTED IN DIFFERENT WAYS, INCLUDING THE CHANGE IN THE SYSTEM OF RAIN MÁXIMO DE LLUVIAS: mm Pico “El Toldo”, HOLGUÍN New Map of Cuba Isoyético Historic Print Media mm MÍNIMO DE LLUVIAS: 400 mm San A del Sur, GUANTÁNAMO Behavior of rainfall from 1901 to 2009

7 V. IMMINENT NEED OF APPLICATION OF ADAPTATION AND REDUCTION OF VULNERABILITY TO CLIMATE CHANGE.

11 SERVICES AND PRODUCTS S H N
Daily evaluation of the Rain (Special Information Network) and reservoirs. Hydrological Bulletin Monthly (Rain, reservoirs, groundwater) Hydrological studies and evaluations Analysis and monitoring of the results of observational networks of the hydrological cycle Extreme rainfall events and monitoring, analysis and evaluation of drought.

12 CAPACITY BUILDING AND DEVELOPMENT OF EARLY WARNING AND PREVENTION HYDROLOGICAL
Program to repair damaged water works by attacks of extreme events Inspection and maintenance of hydraulic structures and channels in order to control and manage the avenues Annual Establishment of reservoirs regulations on "Hydrological Prevention“ Gate operating system and watershed management Development of early warning systems Automation and transmission of real-time alert

14 AUTOMATION PROGRAM FOUR WATERSHED REGION IN THE EAST AND A CENTRAL
The incidence in the eastern region of the heavy October rains and Tropical Storm Noel in November 2007 provided the opportunity to access funding support of UNDP pop a value of USD and EUR 39,307, for the project Caraibe Hycos. These financings were for the partial automation projects (by the scope of funding) Cauto basin, Sagua de Tánamo, Guantanamo - Guaso, San Pedro and Zaza, which sees the location of level sensors, rain, quality of water and communication media for transmitting data in real time. With this level of automation control is achieved through remote terminals 39 distributed representatively, monitoring of rainfall, water levels in streams and reservoirs, and their quality.
