That is the reason for studying unsteady open channel flow in irregular geometries through the development of numerical simulation tools.  the main objective of this work is generating mathematical modelling tools for unsteady open channel flow in irregular geometries, as natural rivers are. The developed numerical schemes are aimed to be able to properly simulate discontinuous flows (front waves, hydraulic jumps, transcritical flows) as occurs during a real flood in most rivers, especially those in mediterranean areas. Explicit numerical schemes, based on the finite volumes technique, for the resolution of the saint venant equations in conservative form, are developed. This shock capturing schemes are most suitable for the simulation of flows with discontinuities. The developed schemes are high resolution schemes: second order precision away from flow discontinuities, no spurious oscillations and no extra dissipation (as with first order schemes) around them.  flow patterns in rivers depend on their geometry. When there exists a predominant flow direction a one dimensional approach can be used, but other times (river confluences, flow around structures, compound channels, river channel overflow) a two dimensional approach is needed. This last one is more expensive as needs more topographic information, model development is complex, and computational time is greater. New methodologies for one and two dimensional modelling are developed, but also both approaches have been integrated in order to be able to model big areas using a one dimensional approach when it is enough, and a two dimensi<\/p>\n<p>&nbsp;<\/p>\n<h3>Datos acad\u00e9micos de la tesis doctoral \u00ab<strong>Modelacion del flujo en lamina libre sobre cauces naturales. analisis integrado con
