CATÁLOGO DE INUNDACIONES HISTÓRICAS

1983: The National Commission for Civil Protection provides the Technical Committee for Flood Emergency (CTEI), with the participation of the organs of state administration competent in this field.

1983-86: We do the work of the CTEI, highlighting the historical flood studies (2,588 flood detected) and potential risk areas (1,036 localized areas).

Comisión Técnica de Emergencia por Inundaciones (CTEI),http://www.inforiesgos.es/es/info_interes/otra_informacion/

1995: Floods catalog Segura Basin (DGPC, UPC of the Government Delegation in Murcia, Segura basin and Territorial Meteorological Centre of Murcia). 1996: It is the State Coordinating Committee (referred to in the Basic Guideline Flood), which established the Working Group on Flood Risk Analysis in Spain. The DGPC presented a technical proposal to address risk assessment studies). 1997: The first phase of the proposal was the elaboration of the National Catalogue of historical floods. To do this, from the experience gained in the Segura basin, develop a methodological guide and promoted, by Circular 4 / 97, the constitution of the various Working Groups basin. 1999: The DGPC compose a work program and convenes a meeting to be made to all agencies involved in the project

GENERAL COMMENTS

Flood Type: field empty (CNIH includes all the flooding that had consequences for the population, regardless of its cause).

- Location: we have included the provinces concerned to make it more homogeneous.

- - Riverbasin: we have included only the most important, yet may be excessive, but there are floods in Spain with more than 30 rivers overflowed.- Fatalities: the social impact data easier to find, although there may be major differences between sources of information.- Injured: insignificant information.- Affected: we considered the field CNIH evacuees (which also include the rescued).- Homeless: has been obtained from the destroyed homes and homeless families and in both cases has multiplied by 5.- Economic impact: there has been no estimate of damages, which generally reflected the damages are real and significantly lower than those produced (for lack of information.) The most comprehensive data from the special committees of the Senate, but only accounted for twice.- Cultural Impact and Ecological Impact: not included this information (in the CNIH is included but not specifically).

PROPOSALS

1. EM-DAT criteria: modified for a European Base Flood Impact.

2. Sources of information: use to very recent events provided official data sources and remote episodes at least two different sources.

3. Flood Type: consider all types of flooding (with its specific characteristics).

4. Location: set the level of detail for harmonizing concepts. We propose the minimum level administration.

5. Fatalities: obtain this information only one source of official data (and add bibliography).

6. Affected: establish criteria and define concepts and their descriptions.

7. Economic impact: establish a procedure requiring a responsible institution in each country to collect this information.

8. Include the following information: Number of affected municipalities; River basin concerned; Data on maximum rainfall, peak flows (associated with the corresponding return period) and area flooded; Houses affected; Damage to agriculture, industry, infrastructure and basic services.
