The occurrence of large floods has increased, contributing to the failure of numerous small dams in Burkina Faso and the Sahelian zone of Africa. Usually, the small reservoirs created by these dams are the only water sources available during the dry season for many villages. Standard approaches for managing large dams do not apply to these small structures, and the purpose of the paper is to review appropriate approaches for selecting the design and flood risks of these dams, and to propose low cost solutions for improving their hydrological safety.

The civil engineering is a great profession. At the present time it is in an uncertain crossroad, and it should confront important future challenges that it is necessary to transform into opportunities. For it, the "Asociación de Ingenieros de Caminos, Canales y Puertos" organized a cycle of round tables on "Challenges and opportunities of the Spanish Civil Engineering" that took place from February to June of 2011. The objective of the cycle was to contemplate and to discuss on the current panorama and future of the profession. The activities of the civil engineering under diverse focuses were presented: from the analyses of the diverse sectors that constitute the marrow of the profession (Public Administration, Construction and Consultancy), the growing importance of the international activities, the necessity to improve, beyond Bolonia, the bases of the knowledge and the formation, the imperious demand of having an engineering more sustainable and innovative, until the demands of improvement of our professional image, making better engineering into the framework of the society. In this communication, the development of the round tables and the synthesis of the reports and discussions, based on three basic axes: Current Topics, Challenges and Strategies, is presented.

This paper summarizes the design philosophies, construction methodologies and essential characteristics of the 28 RCC Spanish dams that are currently in operation (27) and under construction (1). The authors describe their cross sections, their main structural aspects and the basic characteristics of the mixtures used in their construction. Source

Dam Protections against Overtopping and Accidental Leakage - Proceedings of the 1st International Seminar on Dam Protections Against Overtopping and Accidental Leakage | Year: 2015

Burkina Faso is a landlocked country located within the Niger River bend in the Sahel area of West Africa. The total population of the country is around 18 million inhabitants and the main activity is agriculture occupying 80% of the population. The country is located in a semi-arid zone of Africa. The rainfall season is between April and October in the South and June to September in the northern part of the country. Only three rivers are permanent, one with a long duration of very low flow during the year. The country is characterized by a high seasonal and inter-annual variation of rainfall and river flows.Water storage in Burkina Faso is a prerequisite for any human live and activity. Since the 1920’s more than one thousand small dams and around 20 large dams have been built to store water (5.5 billion m3 storage capacity) for multipurpose uses. Due to some weaknesses in the studies and construction and considering the impact of very large floods around 10 dams per year are experiencing overtopping or internal erosion leading to some cases of failures. The profession is trying to address the situation with the improvement of design criteria, construction techniques and the promotion of some low cost technologies to increase the resilience of these structures to resist to large floods. The paper will present the recent developments in design criteria and low cost technologies. © 2015 Taylor & Francis Group, London. Source

The Spanish National Committee on Large Dams (SPANCOLD), the Chinese National Committee on Large Dams (CHINCOLD), the European Club of ICOLD and the Spanish Institute of Cement and its Applications (IECA), in collaboration with the Spanish Ministry of Agriculture, Food and Environment, and ICOLD, will host the 6th International Symposium on Roller Compacted (RCC) Dams, which will be held in Zaragoza, Spain, from 23 to 25 October 2012, prior to HYDRO 2012 in Bilbao. The post-Conference study tour will end in Bilbao, to facilitate attendance of both events. Source
